I was saying that I recommend 940nm or so because I know that that wavelength can be seen by most digital cameras, even cheap ones. There is no need to use an IR filter from most cameras, you should be able to see the IR on the screen without taking a picture. An IR filter is used by people to turn a camera into a night vision camera during the daylight, but if you're trying to use your camera at night you shouldn't need one. However, I bought an IR filter lens for my camera a couple years back for ~$5 off of ebay.
Wavelength doesn't effect safety, except that visible light is safer than invisible light. Safety is primarily effected by the power (brightness) of the laser, which is the mW rating.
