Good read. This reminds me, is there an external IR illuminator review? This topic has come up more and more lately especially as we talk to municipalities.

Nothing recent, mainly because their use has generally been on a downtrend with integrated IR so prevalent. Are you looking for especially long range or?

Understandable. Specifically I’ve started to see LPR at short and long distances where lighting isn’t great and the camera doesn’t have IR (but does have an IR cut filter). I wonder also if AI in general might be able to take advantage of it.

I can also see applications where they aren’t going to do distance security lighting but would like to see basic items at a distance. I’ve seen good IR at distance in built-in PTZ but not on other form factors.

Coincidentally last night I had a customer who is trying out a n Axis Q1700-LE. Reading the material I saw this:

In pitch darkness the camera captures license plate images at up to 50 m (164 ft) and up to 100 m (328 ft) with the optional accessory AXIS T90D20 IR-LED Illuminator.
