This is a great little monitor for the price. At one time it could have been used for a TV. We are selling them as set-up monitors. This is a 2.5 inch diagonal color monitor for use with analog DVRs and cameras. The included AV cable will connect to the SSC-758HQ-N in order to view the settings and also will allow you to position your camera on location without guessing. It can operate from 4 AAA batteries ( not included) or it will operate from the included AC power supply.
