IP intercom adopts leading IPAudioTM technology to transmit audio signals in the form of data packets on LANs and WANs. It is a hands-free intercom system for pure digital transmission. The traditional intercom system solves the problems of limited transmission distance, susceptibility to interference, and the like.
1, the sound quality is clear and smooth, not interfered with by external electromagnetic waves, the occupied bandwidth is only 34kbps, and the latency of LAN calls is less than or equal to 30 milliseconds.
2. The transmission distance is infinitely extended. With the intercommunication of the network, intercom and multi-party calls can be realized, and a wider range of information communication systems can be constructed.
3, using digital audio processing technology, with echo cancellation and noise suppression, full-duplex calls, multi-party calls and zone broadcast can be easily achieved;
4. Confidential call, special audio coding format, encryption processing to prevent eavesdropping;
5. It is easy to adjust the communication scale, and the expansion of the system can be completed by adding terminals.
6, can also be used as an alarm system and broadcasting system (compatible with Shibang IP network public broadcasting equipment).
Spray gun is a kind of equipment that uses liquid or compressed air to quickly release as power. There are two types of spray guns: normal pressure type and pressurized type. The spray gun also has a pressure spray gun and an automatic recovery spray gun.
The spray gun includes a gun body and a gun head, the gun body and the gun head are connected by a connecting mechanism; the gun head includes a nozzle with a number of metal round steel plug welded inside the nozzle; the connecting mechanism includes a flange and a chain pin, The nozzle is made into a flat shape; its replacement is more convenient, the cost is lower, and it can effectively prevent the gun tip from falling off and wearing.
