Digital Video Recorders

Listing ID #2068965

We are offering premium digital video recorders. We offer a range of digital video recorders that is widely required for intense surveillance. Digital video recorders that we offer is procured from reliable manufacturers in the market. Digital video recorders, provided by us, is based on real time operating system that enhances their functionality delivering superior visual output. Clients can use cctv digital video recorder for several purposes. Digital video recorders provides the best monitoring and can also be used for both entertainment as well as commercial purposes. Digital video recorder is vastly used for quality surveillance and for recording operations. Our digital video recorder configured for physical security applications record video signals from closed-circuit television cameras for detection and documentation purposes. Many are designed to record audio as well. Digital video recorders have evolved into devices that are feature rich and provide services that exceed the simple recording of video images that was previously done through vcrs. A digital video recorders cctv system provides a multitude of advanced functions over vcr technology including video searches by event, time, date and camera. There is also much more control over quality and frame rate allowing disk space usage to be optimized and the dvr(digital video recorders) can also be set to overwrite the oldest security footage should the disk become full. In some dvr, security systems remote access to security footage using a pc can also be achieved by connecting dvr to a lan network or the internet. Some of the latest professional digital video recorders include video analytics firmware, to enable functionality such as 'virtual tripwire' or even the detection of abandoned objects on the scene. Security dvrs may be categorized as being either pc-based or embedded. Pc-based digital video recorders architecture is a classical personal computer with video capture cards designed to capture video images. An embedded type dvr is specifically designed as a digital video recorders with its operating system and application software contained in firmware or read-only memory. hardware features of security digital video recorders vary between manufacturers but are not necessarily limited to

• designed for rack mounting or desktop configurations
• single or multiple video inputs with connector types consistent with the analogue or digital video provided such as coaxial cable, twisted pair or optical fiber cable. The most common number of inputs are 1, 2, 4, 8, 16 and 32. Systems may be configured with a very large number of inputs by networking or bussing individual dvrs together.
• looping video outputs for each input which duplicates the corresponding input video signal and connector type. These output signals are used by other video equipment such as matrix switchers, multiplexers, and video monitors.
• controlled outputs to external video display monitors
• front panel switches and indicators that allow the various features of the machine to be controlled.
• network connections consistent with the network type and utilized to control features of the recorder and to send and/or receive video signals
• connections to external control devices such as keyboards
• a connection to external pan-tilt-zoom drives that position cameras
• internal cd, dvd, vcr devices typically for archiving video
• connections to external storage media
• alarm event inputs from external security detection devices, usually one per video input
• alarm event outputs from internal detection features such as motion detection or loss of video

• hard disk support : sata 40gb-4096gb
• compression : h.264, high definition
• channel : 4, 8, 16, 32, 64
