Analog NTSC camera and IR lumination?

[videobruce 0]

My cameras are Bosch analog. I need to provide nighttime illumination for one of them. Will a IR light fixture work?

Hi. It depends on the camera your using 

to use ir with a camera it needs to be day night …. IR only works when your camer switches to black/white a filter either needs to be operated electronically or buy a fixed coated lens

Thank you for the reply, I would of responded sooner, but I didn't get notification of as reply.

Let me ask this; is it because the IR spectrum is out of the visible range, the camera has to be changed over to the IR range from the visible range? Doing so electronically gives the same results as a IR lens  filter or is there a trade off between the two methods?
