Wireless monitoring camera technology to lead off the market for civilian control - civil, control, family - smart home industry
HC intelligent home network Need a monitoring system where a lot of variety of cables laid. The one hand, consumes a large amount of manpower, it also consumes a lot of copper and plastic. Labour life is really a waste of money, waste of resources, contrary to the principle of environmental protection. It is expected that a more simple audio and video transmission. With video compression technology and wireless network technology matures, wireless surveillance camera came into being, making giant strides toward the market.
Wireless surveillance camera is the wireless receiver embedded into the network of new surveillance cameras inside the camera. It uses the WIFI channel, consistent with IEEE802.11B / G standard protocol. WIFI is from the AP (AccessPoint), and wireless network composed of wireless network card. AP commonly referred to as network bridge or access point, it is as a traditional wired LAN and wireless local area network as a bridge between, so any one PC with wireless network card can be shared through the AP to the wired LAN contact or wide area network resources, it works the equivalent of a built-in wireless transmitter in the HUB or routing, and wireless network card is responsible for receiving the signal emitted by the AP CLIENT-side equipment. With the AP, as a general cable network switch or router, generally, the wireless station can quickly and easily with the network.
In short, when one end of the switch connected to the wireless AP or wireless router, wireless AP / wireless router signal coverage, install one or more wireless cameras, make up a simple wireless video monitoring system The audio and video display and management through local area network (wireless network access within or switch) of the computer to achieve, PTZ control via wireless to transmit the same signal. If the wireless AP or router access to the Internet, wireless camera for dynamic DNS and port mapping, the remote audio and video can be monitored.
Wireless signal strength depends on the wireless AP / router, the size and power transmission capability, wireless surveillance camera with no necessary connection. So do the wireless surveillance camera monitoring system will often consider the circumstances at the scene to determine the multi-power wireless AP, or not to add the wireless antenna and the need to increase AP by bridging signals. Even in the more complex environment, as long as these measures can always make a stable wireless LAN, wireless LAN in this, people are free to install wireless surveillance camera has. And in wireless LAN, we do not need to worry about speeds are not enough, because the minimum bandwidth of the wireless LAN is 11M, easy to reach 54M, the next generation of WIFI even reach 540M.
Some people worry that the wireless radiation, which is not necessary. IEEE802.11 provides the transmit power should not exceed 100 mW, the actual transmit power of about 60 to 70 milliwatts, which is what kind of concept? Phone transmit power of about 200 mW to 1 W, the hand-held radio up to 5 W, and wireless networks such as mobile phone usage is not direct contact with the human body, is absolutely safe.
Wireless surveillance camera is a very convenient very green high-tech products, and can sometimes save costs, can not be overlooked is the freedom of wireless surveillance cameras and mobile nature of this workshop on the remote management of liquidity very valuable. Wireless surveillance camera, like other network cameras, is rich in appearance and function. The market has started to launch a wireless home camera, wireless bolt, wireless hemisphere, wireless ball machine products, and accumulated a wealth of wireless Local Area Network and wireless video solutions. Wireless surveillance camera has been successfully applied to the family, school, hotels, construction sites and mines, etc., which fully proved that wireless surveillance camera technology has been very mature.
The use of wireless surveillance cameras, monitoring system, remove the wiring of the cumbersome and heavy, and thus become extremely flexible and lightweight. Wireless surveillance camera surveillance in the field will become the main characters, leading up surveillance market to take off again.
