DVRs: The Workhorse of the Hybrid Digital Video Surveillance

April 1, 2008
SPECO’s DVRs are representative of the new breed of cost-effective digital video processing devices which are redefining video surveillance and security.

The video surveillance market has never been hotter. The challenges placed upon locksmiths and video system dealers are greater as the diversity of applications widens and end-user expectations increase.
The good news is that video technologies are both creating the demand by presenting more functionality, and meeting the needs with more products at lower cost.
The bad news is that the industry is experiencing an upheaval in which conventional wisdom may place a locksmith at a disadvantage, and the new technologies make it essential for security professionals to learn the new video sciences.

Certain brand names which stood for decades as benchmarks for reliability and performance are being suddenly supplanted by a market driven by price. The performance of video systems has always been somewhat subjective as to what exactly constitutes good video.

The market is now filled with new technologies, each of which claim to be the best and some which are totally unproven.

Locksmiths and their customers do not always have the luxury of time or budget to gain a full appreciation of which products and techniques actually represent the best value for their application.
Digital Video Recorder (DVR) is a generic term for a device that is similar to a VCR but records television data in digital on a hard drive as opposed to a VCR tape.To facilitate adoption of DVRs by the market place, DVRs are designed to look like VCRs and have all of the same functionality of VCRs (recording, playback, fast forwarding, rewinding, and pausing).

To say that a DVR “does more” than a VCR is an understatement. The SPECO DVR-4TN we evaluated for this article includes numerous functions and features which far surpass those possible with the VCR.
These days, the influx of imported video and security equipment is no less than a tsunami which threatens to flood the market with unknown entities. Because video equipment has become a mass produced appliance, the video market has become price driven, and competition is fierce.

When you select a piece of video equipment, you are also selecting a partner. You are investing your time and money buying and learning how to use the DVR and putting your reputation on the line with your clients. The DVR manufacturer becomes the locksmith’s partner and ongoing resource, so selecting wisely is critical.
