Network camera is a combination of traditional cameras and the new generation of network camera technology, images can be transmitted through the network side of the globe, and the remote browse Who do not need any professional software, as long as a standard Web browser (such as "Microsoft IE or Netscape) to monitor their image. Webcam to convert images based on TCP / IP network standard data packet, so that the camera images taken by RJ-45 Ethernet or WIFI WLAN radio interface directly to the network, the network canRemote monitor screen. Using the most advanced camera technology and network technology, with powerful features. Built-in software enables true plug and play, allowing users to remove the re-Complex network configuration; built-in high capacity memory storage alarm is triggered before the image; built-in I / O port and communication port to facilitate the expansion of external peripherals such as: access control systems, infrared Sensing devices.
Features
1. for IP network remote video transmission products using MJPEG hardware compression technology, the LAN / WAN on a maximum 30 frames / sec real-time transmission of high-quality Video image.
2. using TCP / IP standard protocol, built-in WEB server, support for web browsing, easy to operate.
3. Support VGA / QVGA / QQVGA three resolutions in support of the video quality level, video display, the use of environmental and other video parameters.
4. comes with infrared light, when the outside is dark, the lights automatically turn on infrared lighting.
5. support through the private network to adapt to more network environment.
6. manufacturers for each device is assigned a unique device serial number, device password and Dynamic DNS (already burned into the device, and record label in the trailer), you do not need any Set when the device connected to the Internet, you can access the device using the domain name.
7. manufacturers offer free client software IPCMonitor, can multi-screen viewing, long time recording, alarm detection.
