The Alro Pro 3 is a top-notch choice for smart home security. features Simple to install and use Easy upgrade for existing Arlo owners Minor performance issues with multiple 2K streams Advanced features require subscription. This review was last updated by Digital Trends editor John Velasco on 8 11 2020.
Since its early days as a quirky offshoot of Netgear, Arlo has found its rhythm with a superb selection of wire-free and weatherproof smart cams. The high-definition Arlo Pro 2 tops our list of 2019 s best outdoor security cameras, and it s a fine choice for indoor monitoring, too. In April 2019, Arlo s Ultra 4K arrived, marking the first shot fired in a next-generation battle for UHD smart cam supremacy.
It boasts superior image clarity and impressively wide vistas, but a 300-per-camera price tag and a restrictive upgrade path for existing Arlo owners meant it wasn t quite a slam dunk. While it lacks Arlo Ultra 4K s headline-grabbing UHD resolution, it offers a broader suite of enhancements that make it arguably a better choice than Arlo s priciest kit.
There s been fierce competition in the space of late but Arlo s outstanding track record has given consumers confidence that this one should succeed. The Arlo Pro 3 499 for a 2-camera kit, with add-on cameras priced at 199 each sits squarely between the two. Arlo Pro 3 review A smart security choice. In fact, its security camera line continues to broaden with recent entries such as the Arlo Pro 3 Floodlight and Arlo Essential helping to diversify its lineup.
Terry Walsh Digital Trends. This new model boosts image resolution ranging from the Arlo Pro 2 s 1080p to a sharper, more vibrant 2K 2560 x 1440 pixels with support for high dynamic range HDRwhich promises better video quality in very dark or bright areas. A 160-degree field of view may be narrower than the Arlo Ultra 4K s generous 180 degrees, but it s a noticeable step up from the 130-degrees offered by the outgoing model. Other features are lifted directly from the Arlo Ultra 4K.
An integrated spotlight allows Arlo to claim support for color night vision, while noise-canceling two-way audio and an on-camera siren further reinforce the Arlo Pro 3 s security credentials. A better choice for Arlo upgraders. It also benefits from the neat magnetic charging system we met in April, which promises up to six months of camera battery life between charges. Visually, the Arlo Pro 3 s cameras and supporting SmartHub look identical to those we encountered when reviewing the Arlo 4K Ultra.
That s not a bad thing as Arlo s much-copied design is one of the more compact and attractive systems around. The curvy, all-plastic chassis is robust enough to weather the elements, while the installation is simplified by a strong magnetic mounting system a screw-mounted option is also available. A partially flattened base also allows the camera to be placed indoors on a shelf or desktop.
In short, you can install the Arlo Pro 3 anywhere. Arlo s much-copied design is one of the more compact and attractive systems around. Also included here is Arlo s latest SmartHub VMB4540which provides network connectivity between the cameras and your router. Again, it looks identical to the slimmer device introduced with the Arlo Ultra 4K, but a closer examination reveals important differences. External video storage for camera recordings is available, but on this model, it s enabled by a single USB 2.
That s good news for surveillance video hoarders, who will benefit from storage capacities up to 2 TB. The Arlo Pro 3 s lower-resolution video also allows the system to operate with reduced bandwidth requirements. 0 port rather than the microSD slot equipped on the Arlo Ultra. This SmartHub operates on 802.
11 b g n Wi-Fi rather than the faster AC standard supported on the Arlo Ultra 4K. Perhaps the best news is that owners of some older Arlo systems can add Arlo Pro 3 cameras to their existing network and receive the benefit of enhanced 2K video streams without the need to replace their SmartHubs. Arlo Pro 3 owners can even add Ultra 4K cameras to their systems at a later date, with no loss of functionality. That makes the Arlo Pro 3 a better upgrade option than Arlo s top-tier kit.
Setup s a cinch. As was the case with every Arlo system we ve reviewed, getting up and running with Arlo Pro 3 is really easy. Arlo recently introduced a new version of its smartphone app, which does a great job of guiding you through installation. Where cheaper smart camera systems can switch between direct Bluetooth and Wi-Fi connections during setup, Arlo s wired SmartHub handles installation smoothly. Hardware installation is equally simple, with screw and magnetic mounting options available in the box.
Arlo s newer, concave magnetic mount is fabulous, balancing strength and versatility. Cameras smartly snap to the mount at the rear and can be angled precisely, despite the firm connection. For more ambitious mounting, the included adjustable security mount can be screwed into walls, fences, ceilings, trees, and so on. It supports 360-degree rotation and 90-degree tilt.
In use, the Arlo Pro 3 s 2K image quality is a noticeable improvement over the previous-generation camera and a huge leap from the 720p supported by the original Arlo system. While it doesn t have quite the clarity you ll get from Arlo Ultra 4K or wired Nest Cam IQ models, it s still very good indeed. The enhanced resolution allows you to take advantage of the camera s 12x digital zoom without images immediately disintegrating into a blurry mess. Arlo Pro 3 is equipped with a smart Auto Zoom and Tracking feature, which is handy for security monitoring.
Push beyond 3x zoom, though, and quality will noticeably degrade. Sadly, as we found with the Arlo Ultra 4K, when the feature is enabled, the camera s resolution is dropped to 1080p. Night vision provides greater sharpness and clarity than many competitors. We found daytime image quality to be balanced, with accurate colors and good contrast.
A step up in video quality. Arlo s Auto HDR feature makes it one of the few smart cameras we ve tested indoors that avoids overexposure near bright windows, which means you ll capture images of anyone peering through your windows to see if you re home. The 160-degree field of view is wide enough to cover all but the most expansive rooms or huge gardens, and fish-eye distortion is negligible.
At night, Arlo Pro 3 s color night vision feature requires the camera s integrated spotlight to be illuminated. The resulting images are certainly more natural than the standard, spooky monochrome pictures produced by competitors. However, while range is good, color night vision suffers from the blurriness and noise typically associated with high ISO photography.
With the spotlight disabled, the camera reverts to a standard night vision setting. Again, the illuminated range is good, and while monochrome images are also a little noisy, Arlo Pro 3 s night vision provides greater sharpness and clarity than many competitors. Piercing alarm, integrated spotlight. While the Arlo Pro 3 isn t necessarily competing with the likes of Simplisafe or Nest Secure as a full-fledged smart home security system, it s equipped with a number of overlapping features that make it worth considering while we await the arrival of the upcoming Arlo Security System.
The piercing alarm from Arlo Pro 2 s SmartHub has been shifted to the cameras themselves, with an option to trigger when motion is detected. The resulting racket is certainly sufficient to scare off an intruder and, combined with the camera s bright, integrated LED spotlight, it forms an effective first line of protection for your home. The Arlo app supports a number of configurable modes to arm the system. Alongside a manual toggle, you can choose to enable monitoring using a timed schedule or geolocation setting.
Each mode can be customized with simple IFTTT rules covering motion detection, video recording, and the integrated alarm, or you can quickly build a custom mode to fit your preferences. It s all very simple. Simple to use, but under the hood, it s super smart. Elsewhere, we found the updated Arlo app easy to get along with. There are only a few ways to tweak camera settings, but they include useful options like brightness, low-light settings, and video quality controls.
Navigating, reviewing, and sharing video clips from the library is simple. A standard daily timeline view is ably assisted by filters that help users zoom in on the action from specific cameras, or review clips based on the type of alert triggered or object detected. Our only criticism with the app is that we found connecting to a camera s livestream could take a while, even on the local network.
On some occasions, we were viewing live video within 5 seconds. Other times, we d experience a delay of up to 30 seconds. With both cameras simultaneously livestreaming 2K video, we did see some temporary performance issues during stress tests. Every 20 seconds or so, both streams were replaced with a black screen for a second, before the livestream was restored.
With 2K local streaming disabled, performance improved, although we continued to see a flicker once in a while. With both cameras reporting a good signal, we can only assume this was a network bandwidth issue or a processing bottleneck. Perhaps retaining Arlo Ultra s 802. 11ac connectivity would have been a better choice.
Intelligent features locked behind a paywall. While Nest often takes the plaudits for smart cam A.the Arlo Pro 3 is equipped with an admirable array of enhancements that add real convenience and utility. Sadly, most are locked behind an Arlo Smart subscription service, priced from 3 per month. A 3-month free trial is available on setup, so you can try out the features and see if the upgrade makes sense. They include advanced object detection, which helps the camera to differentiate between people, vehicles, animals, and packages the latter is currently in beta.
Smoke and carbon dioxide alarm detection sends you a smartphone notification when a camera detects an audible alert. subscribers also get the benefit of an e911 feature, which allows you to call emergency services with a single tap on your smartphone. We loved Arlo s rich notification feature, which adds a thumbnail to the smart notifications sent to your phone. When a person is detected, you ll see a frame captured by your camera. Many smart cams do the same, but Arlo also darkens the image and clearly highlights the person in the frame.
While it s simple to use, Arlo is super smart under the hood. A quick glance and you can check whether the camera s detected friend or foe. With everyday features like custom activity zones and 30 days cloud of video recording also included, Arlo Smart s features work iqoption tournament. Only you can decide whether they re worth the additional outlay. While the Arlo Ultra 4K captured the headlines with its flashy UHD video resolution, we think the Arlo Pro 3 is a more worthy and economical successor to our favorite smart cam for the last two years, the Arlo Pro 2.
It s certainly not cheap, but the Arlo Pro 3 s enhanced image quality, integrated security features, and simple app controls make it a fabulous choice for home surveillance. features that make the Arlo Pro 3 one of the smartest systems around. If you iqoption tournament happy to invest in a monthly subscription, you ll benefit from an extended suite of useful A.
Meanwhile, owners of first- and second-generation Arlo systems have a reasonable path to upgrade their cameras and or SmartHubs. We ve been waiting for a competitive smart cam to knock Arlo Pro 2 off its perch perhaps it was inevitable that the Arlo Pro 3 would do the job. Few smart cameras offer Arlo s winning blend of ease, quality, and versatility, but there are plenty of cheaper systems available if your budget is limited.
The Swann Smart Security Camera 129 is a solid budget pick, with similar wireless connectivity and weatherproof protection to Arlo, as well as 1080p HD imaging. At the premium end of the market, the Arlo 4K Ultra 599 for a 2-camera bundle definitely beats the Arlo Pro 3 on video quality, but you should be aware you ll need to invest in new cameras and a replacement SmartHub to take advantage of UHD video. Elsewhere, Nest Cam IQ Outdoor 399 and Nest Cam IQ Indoor cameras 299 are accomplished top-tier performers that lack the Arlo Pro 3 s versatility and value.
Arlo Pro 3 is built to withstand Mother Nature s fierce temper, with operating temperatures between -4 Fahrenheit -20 Celsius and 113 degrees F 45 Cso expect the hardware to be robust. As for software, Arlo continues to release enhancements and tweaks for all Arlo systems, so we d expect owners to enjoy a long and happy life with the Arlo Pro 3. It s an investment, but the Arlo Pro 3 is a fabulous choice for those considering their first smart home camera system.

It s also worth noting that Arlo has expanded its line recently, introducing new models like the Arlo Pro 3 Floodlight and Arlo Essential.
Artificial Intelligence in Service. Artificial intelligence AI is increasingly reshaping service by performing various tasks, constituting a major source of innovation, yet threatening human jobs. We develop a theory of AI job replacement to address this double-edged impact. The theory specifies four intelligences required for service tasks mechanical, analytical, intuitive, and empathetic and lays out the way firms should decide between humans and machines for accomplishing those tasks.
Rust, University of Maryland, 3451 Van Munching Hall, College Park, MD 20742, USA. The theory asserts that AI job replacement occurs fundamentally at the task level, rather than the job level, and for lower easier for AI intelligence tasks first. AI first replaces some of a service job s tasks, a transition stage seen as augmentation, and then progresses to replace human labor entirely when it has the ability to take over all of a job s tasks.
The progression of AI task replacement from lower to higher intelligences results in predictable shifts over time in the relative importance of the intelligences for service employees. An important implication from our theory is that analytical skills will become less important, as AI takes over more analytical tasks, giving the softer intuitive and empathetic skills even more importance for service employees.
Eventually, AI will be capable of performing even the intuitive and empathetic tasks, which enables innovative ways of human machine integration for providing service but also results in a fundamental threat for human employment.

4mm tag meant to be attached to anything you may lose in your daily life. Vishak tipped us about the iFind Kickstarter campaign, a 1. recycles electromagnetic energy and stores it in a unique power bank. However the antenna was quite big and very little power was extracted. 2uA 30uW in a normal home environment. Our very bad maths indicate that if one would like to extract power from a typical Wifi router located 2 meters from you emitting 0. 5Watts of power in a perfect vacuum environment with a 32 27mm 864mm 0.
000864 4 pi 2 2 8. It is therefore too bad that we can t see in the presentation video what is inside the iFind, nor more details about the patent pending technologies involved. The closest thing that comes to our minds is the Allsee project, a simple gesture recognition device that uses existing wireless signals TV and RFID transmissions to extract any movement that occur in front of it. We hope that our dear readers will enlighten us in the comments section below. The word you are looking for is lose.
220 thoughts on Ask Hackaday Can Battery-Free Bluetooth Item Locating Tags Exist. Anything you may LOSE. ninja edit thanks. 000864m tag you d only be able to get 0. I think I understand this enough to respond like so Yes, it s possible; no, I don t think the amount of power required is feasible. A quick Google search let us know that Bluetooth Low Energy solutions usually consume an idle current of around 10uA.
As you can guess, this particular claim intrigued the Hackaday team given that we never featured so small energy harvesting devices. Unless it also harnesses ambient sound for energy. Imagine never having to charge it up again, but only having to talk. The time is coming soon enough. The very successful Sticknfind campaign which promoted the same battery-enabled product claimed a one year autonomy with a CR2016 battery and a 100ft range, leading to a.
2uA idle current. As we re not expert on the subject, we would like to ask our readers if they ever came across such energy harvesting performances 3V 10. Wish I could be a part of it, but I don t have the time or skills. Those guys managed to get 220uW from a fairly large antenna. Okay, so these tags have a much smaller antenna but they also have lower energy requirements. The paper I linked shows running a clock thermometer that requires 25uA 1.
Speaking of which, I m really excited to wait for the first voice-POWERED bluetooth headset. 5V with occasional peaks of 50uA. So 10uA is the idle current for BTLE, but does it need to be idle the whole time. Since they don t state how often they check if a tag is in range it might only pair once every five or 10 minutes. It s interesting.
Between those times it could be unpaired and completely powered down. RF EM harvesting is tough in the real world because of the environment various, EM field big different even in the same house, direction of wave and receiving antenna, limited antenna size and matching networks for wide-band, antenna gain and signal loss, etc. The energy storage is another issue due to size and density. Some new technology may not available for use with extra thin, and may causing cost too high.
I m following the energy harvesting technology for a while, but not real EM RF harvesting products in the real world for powering RF transceiver, especially for consumer. Current Cymbet CC3150 is 50uAH at 3V, it can t power BLE for half day if you set BLE adverting to 1000mS. The lowest power BLE chip in the world should be Dialog, which avg sleeping current is about 1.
9uA at 1000mS sleep interval. The TX RX averaging over this period about 2uA, then you can calculate without any extra leakage and power consumption. So, I m very interesting for iFind solution which can be used everywhere. Hope to share more from you all. Voice powered should be doable. Voice powered phone systems are still used as emergency comm systems on military ships.
In the early days of telephone systems some quite long runs were done with voice power, then powered repeater amplifiers were added. Need lot of things to learn. Eventually centralized phone system power obsoleted the old tech. If you have an ordinary old phone that draws all its operating power from the phone line, you can still have phone service for a while after a power outage.
Telcos have large battery banks to keep their systems running for several hours. If you have a cordless phone or a phone that does anything that requires it to also be plugged into a power outlet, it ll be useless in a power outage. So if you re a prepper and have kept your landline phone service, you d best get yourself an old school phone. Because the aliens are comin I tell yer.
stores it in a unique power bank Report comment. if i entered a meeting with an investor and dropped that line without further explanation on exactly how it works i would have been escorted out, don t even let me start with an employer Report comment. That s the thing, you re neither to them. But LG would demo it in the store for you wouldn t it. Give, for instance, LG a call and ask them for detailed info on how their LCD screens are manufactured, let us know what they say ;- Tell them your thinking of pre-ordering their latest model but don t believe it works, ask them for a schematic and a detailed report on how they wish to acheive 4k in a 1mm panel let us know how it pans out.
com help guidelines are very clear about No product simulations. It s the dragon in my garage problem. Now LG would gladly and are required to give the customers the power requirements of their TVs Apple will also gladly specify the charger requirements for their products, or back in the day sony wouldn t hide how many AA were needed for a walkman Likewise is no big deal to ask for the Electromanetic Irradiance W m 2 or any apropriate radiometry units needed to power such a device indefinitely so that customers can check if this is realistic with their intended operating environment wouldn t you agree stevetyson2014.
As for power requirements, I agree there too, yes they are obliged to publish these but they are generally quite useless when trying to reverse engineer a product or prove its viability. As soon as they provide credible evidence I will personally get in line and endorse as well as help spread the iqoption tournament in favor but for now the evidence just isn t there. The thread is about whether it can work and howI believe it can, but, only under certain conditions.
They give very little insight into what lies beneath. Their description seems to state it will work ad infinitum which is a little less believable. W m 2 would be useful, not sure how many customers would be able to measure this though. Just to be clear, I haven t found anything to totally dismiss their claims but, like you, would love to see a demo.
If their claims are true then it could be a very long demo. I hate to be that guybut I m with you on this one either they re sitting on something faaar bigger or there are some magical unicorn farts in the mix. It will be interesting to see how this pans out. They don t need unicorns, they figured out zero-point energy. It s like a unicorn but less fun to pet.
Although if we do have unlimited energy and the first use was to find a remote I m hopping on the first super-shuttle off this galaxy. The unique power bank sounds like some sort of super capacitor. super caps are far too large at this point to do anything like this. Not really, they come in all sizes these days. but not in the size required to fit in a package that small while having the necessary current capacity. Don t they have quite some leakage current as well.
I think the supercap capacities of graphene can be laid flat in a very small space with a huge capacity. I could envision radio waves, which are energy always available in the air ,being harvested as a voltage and stored in a supercap. There are supercaps that could do this and with very low leakage current ie 1 μA loss 120 hours. However putting them plus everything else on a device selling for 16 is challenging. Either way they will be using a boost converter so the rechargeable battery tech is a moot point.
Supercaps and to a lesser extent LiPols are considered leakybut the leakage is proportional to capacity internal surface area, more directly. This would most likely be using ambient RF harvesting of some kind Google WISPeither assuming some signal of opportunity HDTV, Wifi or with the Tx device spamming the air with packets, and the tag responding every 1000th packet or so whenever it has saved up enough juice for a single response packet.
The internal power source would only need some mJ of energy, enough to cover one Tx packet and overcome any quiescent usage self-discharge for the power-saving duration between replies. Extraordinary claims require extraordinary evidence. I think it s the claims which are vague yes, it may never need a battery replacement but that must only apply to their idea of normal operating conditions which aren t stated. Yes, it could harvest enough power to do stuff a certain number of times per insert time frame here.
Without normal operating conditions or some, published, assumed usage scenario then it could appear to be a perpetual motion machine and we all know about those, right. Maybe it has its own flux capacitor. Most likely this. Or one of several forms of thin-film battery Cymbet, whoever liquidated InfinitePowerSolutions, etc.tiny LiPol or tiny polyacene cell would do the job. Replying just to say I m using uses quantum top hats to explain unrealistic technology to people now. A 16 ghz ten core processor that uses less than 5 watts of power, and will do your laundry for you.
How did they make that work. Uses quantum top hats, obviously. hahaha i made it up on the spot im glad you like it XD. Yeah that was a badass joke quantum top hats. Really like it too p. The discrediting kickstarter thing is getting a bit tedious. We know it s a cheap way of getting incoming links and page views for hackaday but there IS NO HACK ELEMENT. Come on guys, get it sorted.
Even without the hack element I find it quite interesting to see the method they use to try to prove disprove a concept. Ok, I agree, LG would be able to demo unless you pre-ordered an item which wasn t yet ready for release like pre-ordering a new ipad version. My money is on a small, rechargeable coin cell or LiPo cell. This energy harvesting topic seems quite interesting, actually.
And I m sure a lot of hacking goes into designing something like that if it actually works. Either way, it s something to think about but if you rather yawn, well. There are government imposed limits on the elecomagnetic field strength that the population should be exposed to, to avoid frying their brains and other more subtle problems. The limit is something like 1 mW square cm so, just maybe, it s possible to get enough power in populated areas lots of transmitters of all types.
The problem would be efficiently capturing the energy. If you attached a few tv antennas, a couple of fm antennas, a long wire and ground system plus a microwave dish or two it should work fine. In general, receiving antennas aren t very efficient. B-but muh circlejerk. Speaking as someone just cutting their teeth in the hardware world, it s actually a bit interesting to hear experienced electronics experts discuss How they might go about making this technology work, or why they think it s totally impossible.
You re right, however, that there is no hack here. And this isn t StarterBustersADay. Maybe this sort of content is best left for the forum. Ha, totally tried that fake website. I very much enjoy the technical discussions these bring up, the term Hack is so mislabeled these days anyways. MAKE is more appropriate these days. As long as they churn out 1 Hack Day I feel I m getting more than I deserve.
Yeah hack is an antiquated term. I didn t know we could count on that loophole Good lookin out. There most certainly IS a hack element. They re potentially exposing HACKS here. Just a different usage of the word, that s all. HAD, don t stop these articles. They are great despite what this muppet says. These replies are awesome other than detailless replies and some are actually trying to solve the problem or at least ask questions about the most difficult areas. I must have missed all the other times HaD dismissed kickstarters as dubious.
That s quite impressive of me. I did notice a lot of very dubious projects on kickstarter though, things that get plenty of funding and then never anything is heard again. or they make a billion from selling out to facebook. But without HAD highlighting them, I wouldn t know about these products. And if I don t know about them, I can t laugh at them. They are doing a public service here.
Come on, everyone comes for the hacks, but we stay for the flame. supercap and a mini dynamo. The Dialog DA14580 BLE SoC runs on about 0. 5 μA at 3V in deep-sleep mode. Granted transmit mode is 5 mA 3V note the mbut I guess if they do it very very briefly and then go back to deep sleep it might be possible. Add a supercap and Bob s your uncle. The device just needs to send an advertising packet anyway, nothing fancy. That said they sure look tiny for an RF harvester. May be a embedded coin cell baterry in the tag.
This would give him some time to get the money until the people realized that doesn t harvest anything except his money. ; in spanish we say pelotazo maybe shot in english. Sounds like the shake lights that in the legitimate versions use a supercap about the size of a coin cell battery. The fake ones use a battery, and consequently they work for a few days then poof. Also reminds me of the irritating motherboards with the CMOS battery soldered on.
i see them in those solar powered dollar store lights, i m sure you can find them for smaller. Yes you can use ambient energy in the air to power your BT device, however you just need your ambient power to be high. IE near a radio-station, near a power line. Really you will not have enough power to actually do any real data passing, but if you harvest energy for several days, and only use it for a few seconds.
I have no reason to believe it cant work. that being said there is not a big enough antenna to be broad band enough to actually harvest meaningful amounts of energy. The narrow band power an average device is around is so low you would never be able to gather meaningful amounts of energy, but the power across the spectrum may be enough. when collected over a few days. My opinion with respect to power the radio off BT power Impossible, you are talking about using -40 to -80 dBm of BURST rf power at duty cycles of Report comment.
What about the a c in house power lines. The problem is that the antenna for energy harvesting would need to be quite large. Ideally, yeah. In practice, no. The 50Hz is so prominent that without proper filtering it gets everywhere in electronic Ccts, regardless of their size. A full wavelength antenna at 50Hz would be 5995 Km 3725 miles. I was thinking about inductive coupling, you dont need a huge amount of energy to make this work, but you do need more then is available via the packets you are receiving.
In the near field a transformer coil is sufficient. Even in the far field a tuned-loop can do. But I m not sure there is actually that much noise energy down in this range in comparison to that which comes from intentional radiation. why couldn t they use a coin cell rechargeable. Impressive statement but any antenna picks up all frequencies it is only the filters that take unwanted frequency energy out and feed it back to ground while isolating the wanted group of frequencies.
So with tuned circuitry this can be picked out and channeled to a cap quite easily. Wavelengths that are too long for the antenna will only pick up with greatly reduced power. Teeny antennas only pick up very high frequencies, on which nothing is transmitted at very high power. Yes the signals are still there but at a much much attenuated power level. And if you had a tuneable filter or filters and could tune to highest RX sig strength and harvest from that then you re onto a winner.
With a wideband fractal antenna plus a bank of tuneable filters which are have their frequency pulled by a uC it could work. A uC can be extremely low power and you could have some passive signal strength monitors at common frequencies. Kind of like how antenna diversity is implemented but swap antenna for frequency ie.
dynamically choose the frequency which has the highest rssi and use that for harvesting. I hope to god you are not using enough power to generate strong enough magnetic fields to be useful for this application. i am thinking that you would need several KV and and sever a huge amount of current to make this work I am not saying it is feasible, what i am saying is it is possible to harness enough energy from the air to do things, if you are in a place that has a huge amount of energy in the air.
They don t need much energy and it s all around us, much more than they need. People have been harvesting it for years, the only question I have is what antenna they use and how it s tuned to get the best power transfer at the best frequency and the right time. Just a heads up of the latest comments of this project.
I purchased 3 of the StickNFind location stickers. They did not work very well. Many times the connection was lost and many times they could not be found. I am very disappointed in the product. these StickNFind buttons do not work as advertised. They constantly make false separation alarmseven when the button is within 12 inches of the iPhone it is paired with. have never felt more robbed. this campaign is the reason i would never fund another tech indiegogo campaign.
The shape is too suspicious.
