Prevent camcorder power-downs in video applications Apps
This is a hint that I found on my own since it is information which is *not* in the manual. If you've tried to use your standard digital video camera with iChat, you may find that it shuts itself off after five minutes. Many camcorders include this feature (I have a Canon ZR10) to prevent wear and tear on the mechanisms.

On most cameras, to prevent the auto-power-off, all you need to do is take the tape out and it will stay on. The reasoning is that if a tape is inserted and the camera is on, the video head is spinning which both uses the battery and wears on the tape. If there is no tape, the camera is programmed not to turn off because it is using less battery with fewer mechanical parts working, and no wear to a tape is occuring.

[robg adds: I ran into this while trying to get EvoCam set up; my Sony kept shutting down! After much digging on the net, I found the same answer, and it worked as described.]

Prevent camcorder power-downs in video applications
Authored by: network23 on Jul 03, '03 10:58:24AM

If the camcorder doesn't sense a tape, it assumes that you must be recording to an external deck using the signal out ports. Reasons for this could be the need to record for longer durations or in a different tape format.

Back before there were camcorders, video cameras were two-piece affairs, one huge camera and one massive tape recording deck. When the two units merged and became much smaller, there was still a need to record out to an external deck. I believe that is the main reason why camcorders do not shut down when no tape is detected.

My solution was to record the video onto a tape. This way it knew it was recording. I will have to try this method. I don't think I want to keep rewinding this tape...

Another workaround that solves the problem on some cameras (particularly Sony models) is to switch the device to "Memory" mode (where you would usually take still photographs). This seems to prevent the camera timing out.

Oh, thank you so very much, kind sir!

I was experiencing this on my Canon ZR60 while using iChat AV, and was under the impression that it kept thinking my batteries were failing. I was about to call Canon for tech support, but then I stumbled upon your submission. Thank you very much!

There is one problem with this way. Sometimes on some cameras not all, because my friends doesn't, the camera goes into demo mode, and cannot be turned off. So, while you are talking with your friends on iChat, the camera displays all of its functions, which can be very annoying. But all in all this is still the most effective way for those who have a video camera w/ a firewire port and don't want to shell out the cash for an iSight.

Well, at least I know my Sony TRV-103 has a menu for its functions, and one of them shuts off the demo mode.

Thanks for the hint. I tried it on my Panasonic video camera and it worked!

There is another method of preventing camcorder power-downs.

Instead of removing the tape completely, just set the tape to a non-recordable state... i.e. engage the SAVE mode rather than the RECORD mode on the actual tape.

This works fine on a Canon MV530i camcorder here, and saves a little wear and tear on the tape eject mechanism on the camcorder.
