re: Infrared lights for surveillance cameras

I just assumed any IR light would work.

Any IR light will work, but only if they are day/night cameras.

Regular daytime cameras need an IR filter in front of the sensor, otherwise it'll pick up infrared light and distort the colors in the image during the day, but this prevents them from seeing infrared at night. Day/night cameras flip the filter out of the way at night so they can see infrared when they need to. They usually switch to black/white mode too so the image is more clear.

Already have cameras. ...I'll have to run a motion light in the dark area.

How many cameras are we talking about? It it too much trouble and too expensive to replace them, assuming they are in fact daytime-only?
