I have a very unusual situation occurring in my back yard and I need a good, high-resolution security camera that can identify someone at up to about 30-35 feet. I would prefer a wireless system because I don't want to spend a great deal of time installing it. I would appreciate any recommendations that are based on personal experience. Thanks! . | ||

A trail cam might be a good option if you have a defined area you want to cover. __________________________ | |||

I've got an Arlo system around my house. Works very well, 7-day automatic / free file storage, decent night vision. NRA Life Member - "Fear God and Dreadnaught" | |||

Thanks, Any particular models or brands that you would recommend? . | |||

Thanks. Do you have an idea about how far away your camera can make a solid identification on a person? . | |||

This review outlines pros and cons you can vfc weigh together with actual user reviews on Amazon, Cabelas, etc. https://best.offers.com/best-t...auI15NRoC9zEQAvD_BwE __________________________ | |||

It's going to be a question of focal length, resolution, and sensor size. For example: Here's a UPS delivery guy on a 2MP camera with a 1/2.8 in. sensor and a focal length of 2.7mm at ±35 ft.:  Not really recognizable as anything other than a white, male (probably), UPS guy. Double the focal length and/or the pixel density and you'd probably have a recognizable face. Double them both and you'd certainly have face i.d. Then you have to consider lighting. This was during moderately bright, even daytime lighting. If that'd been nighttime, he'd mainly be blurry shades of grey. Focal length would help with that. Pixel density not so much because, as pixel count goes up, so does noise, and noise is a killer in low light. That's a ±$200 "kind of pro-grade" camera, btw. And not wireless.

^^^ you can't even see what kind of gun he's got in that black holster  Agreed night is tough, and high res wireless and battery won't cut it. even if you could just get power there, then at least you could shine IR out there for better night vision. If you need to know when a person shows up, could you make use of a driveway sensor type of thing ? Then you could just look out the window. . | |||

| Thank you Very little  |
how about motion triggered spot lights to light up the area big time, if you don't have power, solar spot lights up in the trees, add a couple of game cameras to get multiple angles so you can get decent images. | |||

Certainly not at 30-35 ft.
At 30-35 ft. it would have to be a very powerful IR flood. And even then you're still only going to get shades of grey.
Our RAB motion-sensing floods easily trigger on movement at a good deal better than 30-35 ft. for human- and deer-sized targets, out to ±25 ft. for dog-/coyote-sized targets, and 15-20 ft. for cat/skunk/opossum/groundhog. But, even with 3000+ lumens of illumination, those latter animals are only distinguishable on-camera from one another at 25-35 ft. due to their different body shapes and movements. Faces would be indistinguishable. "America is at that awkward stage.

The lights would be good to get a IR camera to flip back to daylight/color and get a better ID. Had a burglar a few years ago, all the outside lights came on, he looked right at one of the cameras and proceeded to spend 45 minutes in my garage, left with a bunch of power tools. He dropped his phone at a neighbors. It wasn't password protected so we just flipped through it until we found his address. Got all my stuff back. Since then I've put in a couple battery powered wireless IR sensors where I have no cameras. There's a box on my nightstand that sounds off a different tone depending on which sensor is tripped. | |||

Do you have a make/model for these? I'd love to get some for my side yard. thanks . | |||

Based on Professional experience. From the limited info given a few more details would be helpful. 1. What time of day is the coverage? 2. What is the level of resolution (this is a highly misused term but will go with that for now? 3. What is the complexity of the "scene" aka busy, quiet, etc? 4. How "wide" of area are you covering? 5. Unmentioned but what are your recording requirements or it just a "live" monitor scenario (unlikely I know)? * Light is the most important factor of all, daytime everything looks great, nighttime or dust the requirements cannot come close to daytime. IR lighting or the use of external non IR lights need to be deployed. Low Light cameras are very beneficial especially in dusk/dawn and even the use of standard lighting. ** Camera "facial recognition" standards are approximately for bare minimum 45 ppf (pixels per foot) and in reality are closer to 100 ppf. The closer you are the higher the pixel count, of course the opposite for distance. *** If your scene is very busy or lots of traffic then this can affect the bandwidth as well as the storage requirements. **** The wider the area of coverage has the same effect as distance on resolution requirements. ***** Combine all of these factors the recording time and space are affected, using compression will reduce this requirements. Current compression standard is H265 and used and configured properly the resolution is minimally affected. Note: Wi-Fi cams are not effective for these scenarios. Find your requirements here: IPVM Calculator Then find a camera based on those specs here : Camera Finder Tool Your going to find that a consumer Wi-Fi cam is most likely inadequate. | |||

Guardline Wireless Driveway Alarm w/Two Sensors Kit Outdoor Weather Resistant Motion Sensor/Detector, $149.00 on Amazon. I've had them for two years and not had a problem. Not changed the batteries yet but probably should. | |||

If you go with a driveway motion type detector, I have a Chamberlin brand on my driveway and have had excellent luck with it. Less than $50 on Amazon for one sensor. The only issue I have (after tweaking where to mount it) is that when it’s windy the bushes on the other side of the driveway will trigger it. It alarms if a car drives up or if someone walks up to my front gate. The unit is around 300 feet from the sensor and picks up great. ------------------- "Oh bother", said Pooh, as he chambered his last round. | |||

I found those sites a few years ago and they're awesome! Concur with the Wi-Fi. All the cameras I have are POE, a bitch to run the cable but worth it. A few words to anyone considering outdoor home surveillance ..... there's a lot of junk out there. There are a couple consumer brands that are pretty good like Hikvision and Dahua but be wary of the gray market versions. Also it's best to stick with one brand for compatibility reasons. As far as operating your system there's software called Blue Iris, cheap, stable and VERY user friendly. The coder is easy to contact and he updates frequently. | |||
