I got a sony handycam dcr-trv19e and when its on and not recording it will turn off after a couple of mins to save the battery which is good but sometimes i plug it into the tv and place the camera near my pool so i can watch the kids or facing my front yard to watch if anyone comes to the door, almost like a easy security camera and was wondering if it was possible to make it stay on and not turn off after a couple of mins
