I pushd a button on my tv remote while facing it in my web-cam.

You can see it flashing

At some remotes if you look at the IR LED wean pushing a button you may see a red spot flashing(in the dark uf course)


PS:
I one time wean i was trying to film a static spark i allmoust blu out my web cam! :? (thank godnes)

This is because unlike our eyes, your webcam sensor (probably cmos) is sensitive to IR wavelengths.

 

You dont need to tell me that some cameras detect IR!

 

Sweet!

 

This has been a standard way of checking IR remotes for years in TV shops - simply point at a CCTV camera and look at the monitor screen.

 

Back in the late 70's when I was still in the service, we used several remotes together to make what we called, "a poor man's night-vision scope". It was brand-new stuff then, but still it was cheaper than the military versions. Just use a high-power remote like a flashlight while peeking through the camera eyepiece. It won't work with all camcorders, so play around with it. On a dark night, very little is more fun than sneaking up on your girlfriend's cat...

HAHAH...awesome...have to give that a try :lol:

 

i've also known noticed that aiming the camera at a tv allows you to see the tv screen refresh!!

The camera seems to translate the IR wavelength into visible light.

The chip in the camera is sensetive to electro-magnetic energy.Linght is just a part of the electro-magnetic spectrum!In there is infraren,gama,microwaves,radio waves...

Or for those that know more abaot electronic than science:

A camera is just a plate of mini LDR whith a lens in front(LDRs detect IR too)

 

The CCD (Charge Coupled Device) in cameras not contains LDR-s....
BTW: all old camera tubes can see the IR e.g. orticon,iconoscope,plumbicon, and vidicon.

 

Well i nont know exatly what is that chip caled.

PS:
I ment all those stuf:
LDR,Light sensitive diodes and transistors...

 

LDR = Light Dependent Resistor, too slow for camera applications.

 

I have the "TRUST SPACEC@M 350 PORTABLE"

 

Aiming the camcorder to the TV, and having the TV connected to the camcorder gives a WOW effect. Try it...
