In today's society, security monitoring systems have become an important force in safeguarding public safety. Whether on bustling city streets or peaceful rural paths, surveillance cameras are like silent guardians, constantly guarding our homes.

However, in the face of the challenges posed by nature, how can we ensure that security monitoring systems are not only "visible", but also "clear" and "long-lasting"? Based on years of work experience, Shanghai Lei Mao engineers suggest the following: starting from the early stages of design, EMC forward design should be carried out. In order to cope with challenges such as lightning strikes and electrostatic discharge, corresponding TVS electrostatic surge protection devices should be configured on the power and signal lines to ensure that the security monitoring system can be seen for a long time.

The security system diagram drawn by Shanghai Lei Mao engineer is as follows:

From the above diagram, it can be seen that in this complex control system, we need to implement electrostatic surge protection for each module and interface, so that the entire system can achieve airtight protection. Engineers are divided into two parts for sharing: 1. Sensor and interface protection, and 2. Power interface protection.

1、Shanghai Leiditech suggests protecting sensors and interfaces in security monitoring，

This section lists the specific ESD protection device part numbers that need to be placed on the interface. If there are any interface protections not mentioned in this table, please contact the Shanghai EMC team for consultation.

2. Shanghai Leiditech provides protection for the power interface of security monitoring systems

Proper surge protection for power interfaces is as important as filtering, sterilizing, and disinfecting the water in a reservoir at its source. Only with proper protection for power interfaces can the backend circuits operate safely.

The recommended part numbers for the power interface are as follows. The specific selection of TVS power and voltage depends on the circuit situation. If you need consultation, you can contact EMC.

2. Shanghai Leiditech recommends MOSFET for security monitoring

 For the power control and driving components MOSFET used in security, engineers have also listed the advantageous components.
