night vision for camcorders?

Q. so i found out that not all cameras can use a IR light source to record in dark
i have panasonic tm700 but i dont think it will be compatible
so is there a list of cerating models of camcorders and DSLRs that will be able to use a IR light to record in pitch black (full HD recording) (preferablt at 1080/60p)
and is the sony a65 going to have support to use ir as a light source


or is there any way to make my camera compatible with IR

A. the CCD sensor itself if highly sensitive in the IR band. so much so that all good quality cameras use an IR blocking filter to prevent false coloring in normal outdoor pictures. no dSLR will have IR capability because they are sold to the photo perfectionist market. Sony camcorders with the "night shot" and "super night shot" feature combine IR with slow shutter, 1/8 second for night shot mode and 1/4 second for super night shot. that is why they have a lot of blur unless tripod mounted. The reason for the slow shutter is because IR has to illuminate the subject, and the only IR illuminator is the little LED on the front of the camera. Some camcorders on the grey market from China (not meant to be sold outside China) have no IR filter and no slow shutter. they work but require a humongous size IR illumination source, like the kind they had on M60 tanks to view at a reasonable distance. and any camcorder can be hacked to remove the IR filter, but one mistake and you have a ruined camera not good for anything. I certainly hope you don't do that to a TM700, but if you are game get something really cheap on eBay and get out the saw. you can find instructions on the net.
Another possibility is to find a camcorder with a poorly performing IR filter. Go to the store and point an IR type remote control at the camera, if you see a light then that is a candidate. Remember you will need an over-sized IR illuminator to go with the camcorder.


For HD camcorders, does 60p mean 60 fps?
Q. 60p = 60fps? They're the same thing?

A. 60p means 60 progreassive while 60 fps means 60frame per second
