Standalone Digital Video Recorder (TWSR-908/909H)

Main Functions
* It uses built-in 32bit micro processor, real-time operations system which guarantees the system's efficiency, reliability and stability.
* Nine channel synchronized recording of video and audio.
* Optional input/output format (PAL/NTSC),
* Each channel's index of video and audio can be set separately.
* Four different recording ways (manual, timing, moving and alarm)
* Easy and quick video replay and indexing. Support quick forward, backward and replay of single frame.
* Support 1/4/9 screen and PIP real-time surveillance and recording replay, which means the replay of recorded video and real-time surveillance can be conducted at the same time.
* The operation and control to the server can be conducted by pressing the buttons on the server, infrared remote controller, and connected PC.
* The standard FAT32 document system enables the recording file can be read on the PC system. The video can also be played with the built-in software.
* It is installed with 4 IDE channel which can support eight hard disks over 200G.
* Strong hard disks management which support the hard disk format and partition.
* It supports TCP/IP and UDP protocols. Through the PC client software and LAN, the user can setup the system's parameters, real-time supervise the video and audio, check the system status, or record the video stream and backup the stored recording and remote control the cradle camera.
* Video moving dynamic check. Each channel can set 64 dynamic checking areas with 10 degrees of sensitivity.
* Video shield function. Each channel video can set 64 shielding areas.
* It provides a RS-485 interface which can realize the real-time control of the camera and cradle controller. The system has several built-in communication control protocols.
* It supports network software update which makes it easy for user to the upgrade maintenance and function expansion.
* Security safeguard functions like system lockout, password check and user authorization.
