I had a DCMA 2500 Wireless Motion Transmitter and receiver Kit installed and was a bit concerned as it is on a steep sloped driveway in the tropics with lot of trees and was afraid it might not be very effective. It has been extremely effective and I would recomment this company and product to anyone needing something like this. The company rep was extremely helpful on the phone previous to final purchase and everything he told me was 100% accurate.

Approximate cost: $400.00
