CCTV with infrared and light with pir

[75pete]

Can I ask, is the light being actuated at night by the infrared given off by the CCTV.
My new set up is, CCTV that has infrared for night vision and a light that has a pir built in, both are in an Inclosed porch.
The light comes on and then off and back on again within seconds when it night. Can this happen, or is the light on its last legs?
The CCTV sits behind the light and throws its infrared onto the porch walls if this helps to explain the setup a bit more.
Thanks for any info.

Probably some IR bounce back.

You need to reposition or mask off the lights PIR.

Some info.

I was thinking along these lines but thought I would just ask the question.

Right, I removed the light that has a pir and fitted a light that's fed from a pir that lives and controls a couple of lights either side of the front garage. Bit of messing about but we wanted to keep the CCTV and light in the porch.

That should have sorted it.
Repost if you could tomorrow to tell us the outcome.
It would be good if others found this in a search.

Thanks

Just returned from a night shift and checking my mail and as I sit drinking a cup of tea before going to bed, saw this from Alarm.
Well it's too light for the the need for the light to be activated so I will check it this night and repost to update.

Well, both the CCTV and the porch light now work without any problem. So, now I have a pir light that I will have to find someplace to fit it, or more like, keep it to use as a replacement for one that fails. Just goes to show as Alarm pointed out, bounce back was the problem.
