Dear Rooney, I have sent an email to RSA, including the specifications and the diagram. Regards, Andy.

I have browsed for more than 50 sites to look for my requirements of Long Range Wireless Survellance System. However, they all look like "toys" for my requirements. Some companies only sell one or two that meet my requirements, but not a "turn-key solution". Could anyone help me to find companies who are in this kind of business? Please find the following specifications: 1. Four cameras. Each is equipped with tele zoom lens capable of 1000 meters of optical zooming range, at minimum. 2. The cameras and transmitters use solar power or any other power sources, but not from an electrical outlet (still need to be plugged in to an electrical outlet) 3. The transmission capability between the transmitters and the receiver must be 500 meters at minimum (taken into account blocking objects/line of sight problem). 4. The cameras can be controlled wirelessly. It includes setting the direction, zoom, etc. 5. Receiver (at least 4 channels). 6. Recording device. Thanks, Andy.
