Then a complete set of wireless bridge monitoring system needs some equipment. Here's a brief introduction:
Assuming demand conditions:
(1) The signal of a 2 million network HD camera needs to be transmitted at the front end;
(2) The antenna is mounted on the signal tower with a distance of 20 km between the two stations;
(3) The distances from the two antennas to their respective bridges are respectively 2m;
(4) The equipment communicates via the 5.8G frequency band;
Required equipment:
(1) 1 set of 2 million network HD cameras;
(2) Concentrate and re-launch the signals of the front-end 31 network HD cameras;
(3) 1 pair of wireless bridges (with a bandwidth of 300M and a power of 1W);
(4) Two outdoor directional antennas (5.8G27db);
(5) 7/8 feed pipe (feeder is generally within 5M, the longer the feeder is, the greater the attenuation is);
(6) adapter;
(7) adapter cable;
(8) Special arresters for wireless bridges (5.8G), two network lightning arresters, and four antenna lightning arresters;
(9) Ground;
(10) Cement;
(11) waterproof tape (large volume);
(12) Two waterproof boxes (one for the front and one for the rear)
(13) 1 network hard disk recorder;
