HD10 Infrared

Just a little off the wall subject. I found out today by accident that the HD10 and possibly the HD1 are able to see IR. To most people this may mean nothing, but to those wanting to shoot night shots you can throw a medium size IR emitter on it or hold one and shoot in complete darkness. I don't know if anyone else realized this but just thought I would toss it in.

Cool! Yes it does see IR!

Here's the easiest way to check it (No dark room required):

- Grab some IR remote, press a button, and look at its emitting diode. You won't see anything.

- Do the same thing with the HD10 pointing at the diode. On HD10's monitor, you'll see that the emitter is blinking brightly!

Have you tried it with an IR emitter? It may not be able to see anything.

The DVX100 can see IR as a red light, so people speculated that it could see in the dark as well. But it can't. I broke out my old Sony HVR-IHL (I think that's the part #), which is an infrared light that lets the Sony NightVision system see about 100' away. Tried it in a pitch-dark room with the DVX, and got flat-out nothing. Just the tiniest weak red glow from the light itself.

As I understand, most cameras have a filter to prevent the IR spectrum from entering the picture. I'll bet the JVC is the same way. Try it with an infrared light emitter, I'll bet that at most all you'll get is the faintest red glow from the IR light, and nothing illuminated by the light.

I haven't used a large emitter yet but I have used a small emitter and pointed it at a close object and got light bouncing back. I plan on trying to use a larger emitter soon and I'll post the results.

Sure, It'll see IR, but it still has a filter to get rid of 95% of the IR. When you video a bright IR source like an LED, it will show up.
The night shot cameras flip the IR filter out of the optical path when in night shot mode, so they can see much better.
