Computer based DVR system
PC based DVR contains all the usual stuff (motherboard, network card, video board, hard drive and memory) but it also includes DVR capture card. This DVR capture board can have 4, 8, 16 or 32 video inputs. The video inputs receive analog signals from the cameras and are converted to a digital format and then compressed using mp4 compression. The compressed video is stored as data on the hard drive for archiving and playback. PC based DVR’s provide far better video recording clarity over time lapse and are generally more flexible than standalone DVR’s. DVR’s have off-site viewing functions that allow you to view your cameras and recordings from anywhere in the world over internet connection.
Stand-alone DVR System
A stand-alone DVR is a computer board built on one complete circuit board. It looks very similar to a VCR, but it has the entire components that a regular computer has. The system runs on an operating system that is built into a chip / flush memory. For that reason Stand-alone DVR’s are extremely reliable and very easy to install and use. They are usually managed and configured by a remote control like a VCR.
In general PC-based DVR’s have much more advanced features than stand-alone models and their processing power is stronger giving them the ability to process images faster and better. They also are better suited for upgrades and system expansions, and for this reason most large institutions such as banks, malls, and airports utilize PC-based models rather than stand-alone DVR’s.
