Difference between "select camera" and "camera on"

So, I've created some macros, but I'm wondering what is the difference between "camera on" and "select camera"? If they are set up in a camera group, it will automatically turn the selected one on and the others off. Currently I'm using camera on, and then when I get an off command from the sensor, I stop still recording and turn the camera off. Is there really any need to ever turn them off? Does it hurt for the last active camera to be left on for an unknown amount of time?

it is a good idea to turn them off!
I have a very old wired x10 cam that suffers from image burn in!
I'm not sure how long it took for this to happen but it now has a ghost image that appears when I pan it to a new location!

Must be very old. Phosphorus cameras did suffer from burn-in; the new CMOS types should not.

Yep one of the first few sold!

True but best to play it safe, also if your using cams with IR the lights will last longer!

For what it's worth...
While you can turn off the wireless signal, you can't turn off the wired signal from a Sentinel camera unless you cut power to it.

I agree with you that it is always wise to save power. And any electronic device will last longer with a lower duty cycle. It's very hard for an electronic device to fail when it's turned off.

But IR LEDs should last between 50,000 and 100,000 hrs. (that's 5.7 to 11.4 years) even if left on constantly.

Should is the majic word, one of my Astak cams is down to 3 or 4 lights working from 12

It may be the LEDs like you say, but it could even be something else, i.e. failed solder joints (from temperature cycling). I've seen failures like that before.

HI. Jeepr

How do you select camera on?
