Does the camera need to be wired in order for motion detection to work?

[Warpped88]

I'm considering the purchase of the Pro 2. It has all the features I'm looking for, but I'm unclear about motion detection.

 I want a wireless outdoor camera that detects motion. Does the camera need to be wired in order for motion detection to work?

Thanks

On the Pro2 the cameras use a PIR device ( detect infrared, much like a floodlight outdoor sensor  ) .

It does not need to be wired ac to work ( self contained battery ) but if it is you get a "3 sec lookback" feature as it is recording all the time and adds the prev 3 secs to the triggered file.
