In an effort to increase our gate security we just implemented a new camera system at our gate. This allowed us to place a camera that faces the rear of the car to capture license plate numbers to go along with our current WiFi intercom. Since our gate is around 1500 feet away from the building this proved to be a challenge to find a system that would handle this distance. We contacted IntercomsOnline.com and they recommended their wireless video transmitter and receiver which has two access points and a high-definition camera that can be focused towards the rear of a car.
The system is working great!
