Full digital control
When the security market to launch digital control, front-end equipment has been fully entered the full HD mode, but did not open the whole digital model. The back-end region free dvd storage equipment, what should we do? Hard disk video recorder family of three brothers launched a fierce dialectical, how to use, which is used in the field as the brother several hot debate. We have not said, or have a look they say.
Video three brothers elder brother is digital hard disk recorders, it gave himself an English name is DVR, it sounds very modern, this product in the security industry is " the old ". Since the beginning of contact security products, DVR attention was gradually increasing trend. It is a collection of video, image segmentation, PTZ control, alarm, transmission and other functions in one.
In the product application, eldest brother seems to have an unusual presentation. Don't look at it have a name in the " D ", in fact, and it matches the front camera is the simulation equipment. For analog camera, whether products or internal technology has been very mature; in the design, the various manufacturers of DVR similar, if you really want to segment words, then to see whether it supports audio transmission and HDMI high-definition interface.
The DVR also features the largest is and what it with analog camera, a camera connected to a video input port, XX DVR represents its support for the maximum number of front-end equipment; big brother said, don't know to monitor people can take it as a home DVD, only behind the interface into BNC, the remaining functional everything. When with the front-end equipment is switched on, using the VGA interface access display that can see in the image.
Regardless of the choice of three brothers who, most concerned about is the image resolution. DVR is not related to network bandwidth, so it can support the multiple video images, but for multi-channel playback can sense is not the same. Big brother is not old spirit, Zone Free DVD dab6d28ck can support 1 D1@25fps image playback, the remaining channel maximum support real time CIF. I can responsibly tell you, general D1 effects should be fully able to meet most of the demand for monitoring.
With the boss character, listen to the words of the little brother. In a front-end equipment to open the whole network era, VCR 's second child was born, red wine in the name of making a small change in -NVR. Network product mix is a network monitoring cameras, but also with simulation is different, is not it BNC replaced by LAN network; compared to DVR, NVR in building monitoring system is a necessary equipment - switch.
