10-50km Remote Outdoor COFDM Transmitter for Wireless Surveillance System

1

Common video interfaces, connect to an ordinary analogical camera directly. 

2

Water-proof, AC 220V (can be ordered 12-24V for solar power interface), adopted different cores in order to distinguish from other interfaces, prevent from destroying the equipment by accident. 

3

Use with 24dBi directional antennas. Transmit 35-50km in the general urban environment, 80 km on sea-level.
