I already have one of these and just needed a 2nd one so I'm very familiar with it's operation. Camera works great. I'm very happy with the camera and the price. This camera depending on the recording time can record continuously for 61 hours on long playing (LP) which makes it a great daytime surveillance camera. The other recording times for high definition (HD) is 20 hours and 30 minutes and standard speed (SP) 29 hours. BUT MAKE SURE IT IS PLUG INTO THE WALL for these long recording times.
