The compact indoor scanner, EF701 is ideally designed for use with compact CCTV cameras. Using plastic steel construction and heavy-duty roller, this easily installed indoor scanner offers excellent durability. It scans automatically or it can even be manually controlled (controller EF702) from left to right up to 360 degrees. The indoor scanner is an excellent solution in places where a stationary camera is not able to view the whole area. If the indoor automatic scanning isn't enough and you would like to be in control of the where you camera is looking at, than the EF702 controller is your perfect solution. The EF702 controller is fully compatible with the EF701 scanner. It gives you the ability to control the scanners movement left to right manually by a press of a button.
