Thanks very much for your reply Ban...even if you only have a tortoise
Cheap >1mW lasers are inoffensive to the eye in way that the
natural reaction of closing eyelid (even for Sasha,my cat! ;-) ) is
well fast enough to prevent any damage. For infrared, i when it
comes to intense light...i just preffer to be able to see the light so i
know exactly where it is. That's why i'm more scared by a class1
IR ,very narrow beam angle, laser from a CD player than a class2
visible red laser. You're right for wireless room monitor, i admit that
they're more popular than my idea...lol
For your focussed infrared led suggestion...i bet it would be considered
here the only safe solution by our provincial health and safety
administration. In Quebec, when it's about to child safety, whe are 1st!
:-) But curiously, abused, beaten child are in most cases left with their
parents! That's safety!
