Just as the name denotes, surveillance DVRs come in various models and configurations. They are not limited in scope to the number of cameras they can support but their efficiency is determined by their functionality laden features as well.
Depending upon your specific requirement, you might need a very simple ''Stand Alone' Digital Video Recorder that can support four cameras and give enough coverage for the outer periphery of your house or alternatively, secure your small retail store enough to deter a wood be shop-lifter for fear of being caught on camera.
For more specific requirements, you can select from a very wide array of specialty surveillance DVRs that offer multi-function capability.
These DVRs are available in 'triplex', 'quad', 'pentaplex' as well as 'hexaplex' models. If you only require a simple DVR that can record, store and playback, the Triplex would be an ideal choice. If you need simultaneous record, store, playback and additional features like network access and remote messaging capabilities in your DVR then a pentaplex or hexaplex DVR would be your ideal choice.
Another determining factor for a DVRs price is its storage capacity (the size of built-in Hard drive) as well as functionality to see how long the hard drive can record. The main recording functions can be selected in terms of: Continuous, Motion Detection, Sensor Triggered, Time Schedule.
One of the latest trends in Surveillance DVRs is the advent of H-264 compression technology. This particular advancement goes a long way in identifying the perpetrators, in case a crime has been committed against the facility where these DVRs are properly installed. H-264 compression gives you sharper image, at a higher resolution and you can also connect it to your high definition television through DVI interface.
