A question on how to use a PIR sensor.

[Jeroen1000 0]

Hi there,

 

I'm trying to improve detection so I want to connect a PIR sensor to a Dahua SD42212SN-HN and have it start recording when motion is detected. So I don't want to use image detection any longer

 

Can someone point me in the right direction as I'm still in the basic stage of understanding.

 

- How do I power the PIR sensor? The camera is powered by POE+ (= IEEE 802.3at)

- What is the camera expecting as an input alarm signal? Is every PIR sensor compatible (don't want to ruin the camera)

- Is the detection range (width and length) adjustable? I want to detect an area of 30 meter deep to 15 meter wide

- Will it all go wrong if it is in the sun as the sun gives off infrared too, or more general, can PIR sensors be easily subverted by a burglar?

 

 

And in stage two, I want my floodlight to go on at the same time. It would be nice if that can be done with one PIR sensor. Sorry if these all look like stupid questions
