Signal converter, video switcher
The signal converter is used to convert the signal of the indirect networked host into an intermediate network device of the networked signal. When a host has a network line interface, a dedicated signal converter product is not required. The video switcher is used to switch the unit video signal to the network bus video line when the individual system is connected to network, so as to better improve the point-to-point transmission quality of the networked video signal.
Host selector
If a doorway has multiple entrances and exits that need to be installed at the doorway host, if the selected doorway host itself does not have a multi-door machine parallel function, the signal switching function of multiple door-to-door masters can be realized through this device; The door host itself has a multi-port machine parallel function, so the device does not need to be used.
Network aggregator, hub, digital signal converter, optical transceiver
When a large-scale cell is connected, the signal is attenuated or interfered in the transmission, and there are many wirings. Through such devices, the distorted signal can be restored to the greatest extent to meet the long-distance transmission, and the individual analog signals need to be transmitted over long distances. TCP/IP converters or optical transceivers transmit for better results.
Electric lock
Its internal structure is mainly composed of electromagnetic mechanisms. The user can press the electric lock button on the extension to energize the electromagnetic coil, so that the electromagnetic mechanism can drive the connecting rod to control the opening of the gate.
door closer
It is a special automatic closed door linkage. It has a regulator that adjusts the acceleration and force, making it easy to use and flexible.
