Glossary in the field of network video monitoring

Web camera

A video camera is usually used to chat via QQ or MSN. Web camera usually uses CMOS for photoelectric conversion. signals are transmitted through the USB interface, which can be decompressed, without dedicated video processing chips.

IP camera

IP camera can be simply understood as a camera with an IP address, or IPC for short. IPC is a complete embedded hardware and software application. Common IPC has CMOS/CCD, general CPU, graphics and image processing chip DSP, and Ethernet network interface. The SD card interface and WiFi module are also advanced. IPC has become popular in recent years. With the intelligence, networking and miniaturization of monitoring equipment, IPC is undoubtedly the representative of this wave of trends.

DVS

Digital Video Server. Digital Video Server. It can be viewed as a server dedicated to digital video signal processing. Generally, it has powerful video processing capabilities and can process multiple video signals.

The video server provides embedded web services. After a video server is deployed at a monitoring site and connected to the camera, you only need to log on to the video server over the network to view the monitoring images. Because of the TCP/IP architecture, the video server is very convenient to use. Any monitoring site only needs an IP address and can be configured with a fixed IP address to install the video server.

A standard video server also requires RS232, rs422, or RS485 control interfaces and level input/output interfaces. The serial port can be used to conveniently implement remote control of cameras, cloud platforms, and other peripheral devices. The level input/output interfaces can be used to achieve smoke, temperature, and other alarm input and linkage output, quickly responds to abnormal conditions of monitoring sites. The video server has been widely used in remote monitoring systems and has gradually replaced the Remote Monitoring System of analog optical transceiver.

DVR

Digital video recorder. Digital video recorder. Developed from traditional monitoring recorders. A large-capacity DVR can be used to record real-time surveillance videos for dozens of days. In some DVR products, the video server function is integrated to provide web services for remote monitoring while implementing multi-channel image recording.

Megaeyes/Global eye
