DVR-470Q network digital video recorder is an excellent digital surveillance product. It uses the embedded MCU and real time operating system, combining the most advanced technology in Information Industry such as video and audio encoding/decoding, hard disk record and TCP/IP. The firmware is burned in the flash, more stable and reliable.

DVR-470Q device has both the features of digital video recorder (DVR) and digital video server (DVS). It can work stand alone, also be used to build a powerful surveillance network, widely used in bank, telecommunication, transportation, factories, warehouse, irrigation, etc.
