Compensating for narrow IR lighting

[Kevin Michaels]

I suggest you go with Starlight camera, so you will see the whole image at night are much more brighter expert on Dahua and Hikvison Product, if you need more detail information , feel free to let me know

I already have Starlight cameras, as I said in my original post. The IR on the Starlight is what's causing the problem. And I don't think your statements about IR range are correct. There are many products out there for illuminating large areas.

Wondered where that "uninformed" post went

Okay, pretty much solved my problem with this IR illuminator. I also turned off the onboard IR lighting. Attached are before and after photos. The lighting still isn't uniform, but the edges of the image are brighter than they were before.

So I was checking out the IR light on amazon and noticed it said on the back of the unit "Keep the photocell downward to avoid sun exposure". Does sunlight wear the cells down? The spot I'm looking to place this is pretty much in direct sunlight most of the day.

Big improvement Kevin, where is the external IR mounted relative to the camera?

Also have you checked to see if there is more wash out of people/faces with the external IR vs the onboard?

I haven't done a comparison with faces, although I probably should. I was just pleased that I could see more detail in the margins than before.

The external IR is mounted two rafters in front of the camera. You can just see it in the upper left corner (note how the rafter tail was illuminated before and is in silhouette now. The light is the bump on the bottom of it.) One more thing I'm going to try is tilting the camera down just a bit more to eliminate the hotspot on the beam over the deck. Hopefully that will help even out the exposure.

There's probably plastic over it and it would help keep water out.
