The security DVR system has evolved as a surveillance tool which is appropriate for residential as well as commercial surveillance needs. These systems have replaced the VCRs and multiplexers due to the advantage of being technologically advanced. They record the video footage on a hard drive-based medium which eliminates the requirement of a videotape. A security DVR system is available in two different types' namely- PC-based models and Stand-alone units. The PC-based models are equipped with several unique features including face recognition, unattended object detection, and more. Security DVR systems have rapidly gained popularity and are preferred over VCR's as they are efficient enough to manage multiple cameras at the same time. Apart from this, these systems can also record and playback the video locally as well as via internet. In the stand-alone units, the user is provided with the facilities like simultaneous viewing, back up and recording. These systems are considered as one of the best surveillance solutions as the recorded video by them can be easily viewed by operating a simple push button. The need of PC is eliminated in this system. While in the PC based security DVR systems, analog signals are converted into digital signals and then later compressed. The compressed signals are stored on a hard disk for further processes like archiving and playback. This system provides the users with a facility to search and retrieve images and videos of anytime. Security systems provide the users with ability to record video for a longer time period. Besides being easy to install, these systems are easily affordable and highly efficient.
