Suggestions for a DIY perimeter alarm system?

Dear JD,

Thanks for getting back. I used to have an Arlo (old one) setup in the past.

What I really want is a system with zero cloud dependency. I was looking into integrating some IP cameras with software like Sighthound which can differentiate between motion and people.

I want smth that can trigger an alarm ONLY IF a human is seen in the perimeter.

I am looking at 6 cameras so cost is another consideration, apart from local operation.

I have seen the Blink XT and the Netatmo welcome.

Thanks for letting me know about the PIR motion sensors.

Please get back with any thoughts/suggestions.

Thanks a lot

Most Devices designed for outdoor use use zigbee, not zwave, because zigbee travels somewhat better through rain, snow, and high humidity because of the type of signal modulation it uses. (DSSS vs FSK). Or they use other frequencies altogether. So there just aren’t many outdoor security systems based on Z wave.

Add to that that these days most outdoor security cameras have their own built-in motion sensors which will work much better then separate inexpensive PIR sensors for a number of technical reasons, and I think most people would just approach this problem differently. You select the cameras that you want and choose a system with built in motion sensors and sirens. And maybe you add additional inexpensive motion activated lights as well.

But I don’t see many people using standalone motion sensors outdoors these days. They just get too many false alarms.

One of the most popular DIY camera systems is the Arlo and there is an option with a siren.

But there are a number of other brands as well. So I would start from the cameras and I think you can find a combination of features that you want that way.

If you really want to look into outdoor motion sensors, there is an FAQ in the forums with a lot of discussion about many different options.

I am looking for outdoor motion sensors to monitor my yard. I bought a pair of the Aeon Labs Aeotec Z-Wave Multi-Sensor and am quite unhappy with them. Even on the lowest sensitivity setting it randomly sends alerts, some perhaps due to clouds changing the lighting (even though PIR is not supposed to be susceptible to this) and others I can’t explain at all. With several false alerts a day this thing is just useless. The Smartthings Motion sensor works great, I have some in my house, but it is indoor rated only. The Schlage / Nexia motion sensor is also indoor use only. I am hoping someone has come across an outdoor rated motion sensor they have been able to pair with the Smartthings hub.

But if you want cameras anyway, I’d just start by looking at cameras. [:sunglasses:]
