A Hybrid DVR (Digital Video Recorder) is commonly used for surveillance that allows its user to connect both on analog and IP camera to the existing or new surveillance system and store, manage and view videos. Network IP cameras or IP camera enable viewing of live video through the digital packets over the Internet. Analog or traditional cameras capture content that cannot always be broadcast for remote access without using the means of an analog to the digital conversion process. Hence it cannot be accessed from one remote location instantly.

Today’s IP video systems have best-sophisticated analytics and megapixel cameras. Today also, around 60 percent market of video surveillance cameras still uses analog cameras, which are connected to the standard digital video recorders (DVRs), thanks to the availability of Hybrid DVRs that has boosted migration from standard analog to IP system.

There is one more concerning factor for companies who want to add Internet Protocol cameras to their already existing analog systems. Earlier, IP cameras needed Network Video Recorder (NVR) or Video Management Software (VMS). To manage and view all the footage on the same system itself, firms also needed encoders (video servers) that allow digitizing analog cameras’ signals.

However, today Hybrid DVRs become mainstream that allows direct connection on both IP and analog cameras while allows storing, viewing and managing videos. These systems enable remote viewing along with good user interface and analytic that can integrate with remote storage, third-party setups, and access control systems.

Choosing the best Hybrid DVR:

Selecting the best in Hybrid DVR requires a few considerations that are: The need for camera count. A standard Hybrid DVR usually supports around 8 IP and 16 analog cameras. For a big space more than three to six hybrid DVRs are required, and for the small area, even one is enough. But with big spaces, one central server and encoders can be used. The advantage of this system is: Instead of logging into each device, manage everything on one single system. If there are more than 50 CCTV cameras, it will be beneficial to shift on encoders. Even the frame rate affects when more cameras are used with a hybrid box. For example, if one hybrid unit is supporting 24 cameras, then the frame rate will be less than the standard 30 frames per second.

While all DVR retailers have hybrid DVRs to offer, not all VMS retailer offer hybrid NVRs. That’s why while choosing VMS that doesn’t support hybrid form, going for encoders will be the best option. Also checking which IP cameras work with hybrid DVRs is the must.
