Can't you set the recorder to do motion or continuous at the relevant times required?

i wouldnt advise powering down the nvr like that, it will kill it eventually.

I thought it a little unconventional . . .

OK - thanks for the advice.

 

In that case I'll just leave the NVR powered up continuously and connect the IP cameras to a small POE switch powered from the Ion OP as suggested by Datadiffusion.

 

The maximum power draw will be 30W with 4 cameras connected.

That should be better. In any case, it will almost certainly be a 'soft start' from the PoE router.

 

As I say, crashing the NVR off probably not a good idea

Bear in mind that when the cameras come online the DVR will detect 'movement' by virtue of going from black screen (no input) to picture restored. When the power goes off you'll get more 'movement' detected.

Maybe not what you're intending.
