The Bluetooth module in the intelligent security system needs to have characteristics such as low power consumption, high security, stable connectivity, suitable transmission distance and penetration, small size and easy integration, multi device connection capability, anti-interference ability, and fast response. The SKB369 Bluetooth 4.2 low-power module from Tiangong Measurement and Control is suitable for devices with strict cost and power requirements, such as Bluetooth door locks, sensors, etc; The SKB501 Bluetooth 5.0 module is suitable for intelligent security scenarios that require high transmission distance and performance, such as large venue security monitoring, remote intelligent door locks, etc.
The Bluetooth module in intelligent security systems usually needs to have the following characteristics:
1. Low power consumption
The devices in intelligent security systems usually require long-term operation, so the low-power characteristics of Bluetooth modules are crucial, which can reduce the energy consumption of devices, extend battery life or reduce energy costs.
2. High security
The security system involves the safety of personnel and property, and the Bluetooth module needs to have a high degree of security to prevent data leakage and illegal intrusion. For example, supporting data encryption, identity authentication, and other functions to ensure that only authorized devices can connect and access the system.
3. Stable connectivity
To ensure that the Bluetooth module can stably connect various devices in the security system, such as cameras, sensors, door locks, etc., to avoid connection interruptions or signal loss, in order to ensure the normal operation of the security system.
4. Transmission distance and penetrability
According to the specific application scenarios of the security system, the Bluetooth module needs to have appropriate transmission distance and penetration capability. For example, in larger places or environments with obstacles, Bluetooth modules need to be able to stably transmit signals within a certain distance and penetrate objects such as walls, doors, and windows to achieve effective coverage of various areas.
5. Small size and easy integration
Security equipment usually has certain limitations on space, so Bluetooth modules need to have the characteristic of small size in order to be easily integrated into various security equipment without occupying too much space.
6. Multi device connectivity capability
Being able to connect multiple security devices simultaneously, achieving interconnectivity and collaborative work between devices, and improving the intelligence and management efficiency of security systems.
7. Anti-interference ability
The environment in which the security system is located may have various wireless signal interferences, and Bluetooth modules need to have strong anti-interference capabilities to ensure stable operation in complex electromagnetic environments.
8. Quick response
In security systems, such as access control systems, alarm systems, etc., Bluetooth modules need to be able to respond quickly to achieve timely unlocking, alarm and other functions, improving the real-time and reliability of the system.
