The security monitoring is an independent complete system constituted from camera to image display and recording by using various transmission channels to transmit the video signals in a specific environment. It can reflect the monitored objects vividly and realistically and in a real-time manner. It can realize the long-time monitoring by replacing the manpower in a harsh environment so that the supervisors can see all actual situations occurred at the monitored site and record them through a video recorder. Meanwhile, the alarm system device will alarm for any illegal intrusion. The alarm signals are input into the alarm host, while the alarm host will trigger the monitoring system to video and record it. Due to anti-terrorism and smart production rapid development, the security monitoring industry has also been rapidly developed.

The security monitoring industry has a relatively high signal bandwidth requirement for the transmission path because it transmits the high-definition video images. The traditional security monitoring solutions use the optical fiber and coaxial cable and other wired methods to transmit the signals. However there are problems such as difficulty in wiring and high cost. The security monitoring industry changes from wired transmission mode to wireless one.

4G LTE module is suitable for security monitoring industry due to its characteristics of high transmission rate. GosuncnWelink’s ME3630 4G LTE modules adopt the
Qualcomm’s MDM9607 industrial-grade chip solutions, with downlink transmission rate of 150 Mbps and uplink transmission rate of 50Mbps, which can meet the demand of the security monitoring industry for wireless transformation.
