Wireless PIR triggers?

Recommended Posts

So I've installed the 8 Channel SWANN Costco special. I've moved the motion sensitivity as low as it will go and made the detection area tiny (three boxes total on at least one camera). I'm still getting flooded with 100+ emails per night and I am interested in PIR triggers.

 

The cameras can be triggered from alarm inputs on the DVR, but I have never implemented PIR triggers on a CCTV system before. A few questions:

 

1. I see a lot of "wireless" home security products out there. I know they are less reliable, but I am wondering if it possible to use one of these wireless PIR sensors with some kind of receiver co-located at the NVR to trigger the cameras?

 

2. If not, do the alarm inputs provide any kind of power to the PIR device if it is wired? I would assume the PIR device would need some kind of external power input?

 

If you've done this before and can recommend specific PIR products, I'd greatly appreciate it. Thanks.
