System function
* image using point-to-point transmission technology, effectively avoid at a high level image ghosting or fuzzy phenomenon
* the system can be applied to large intelligent visual networking community, system capacity with 9999 extension, 99 buildings, each building unit 9, 9 fence machine, a management machine, about 89901009 households; Connected to the Internet using RS485 communication; Strong anti-interference ability, stable work
* the host/extension/machine/management of walls, any two parties can be implemented
* an extension with emergency function
Camera host * USES backlight compensation function, effectively avoid bright light, abnormal image distortion, at the same time, the camera using standby loss of control electric circuit protection, effectively protect the camera, in order to reach the purpose of extended product life
* short circuit protection, each extension adopts neighborhood, fault isolation, and in extension system failure will not affect the normal operation of the whole system
* support extended one more machine function, support for multiple access at the door
* engine room number only within the extension
* extension with calling a secret, every are independent of the unlock password, the password can be set
* keys have noctilucent function and dark environment conducive to the operation
* the host has electricity mortise lock, electromagnetic locks, electric control lock unlock function
* the host can do ID, IC entrance guard function
* aluminum metal shell design
