If your CCTV system uses a DVR, it may be time to consider upgrading to a Network Video Recorder (NVR). This newer technology is now available in a price range that makes better video surveillance accessible. Here we will review the changing technology that brought us to where we are in current CCTV systems, and the advantages we now have with this technology.
Original Analog Technology
Analog was the original technology for CCTV systems and it served a purpose, recording activity on the property for future access and review. It did not, however, broadcast live information which is how we now use CCTV for monitoring purposes. Analog picture quality was low and often unusable for identifying individuals; it also relied on staff changing the tapes regularly.
The Digital Difference
Digital systems revolutionized the way we use CCTV for security. A live broadcast is now available for monitoring from either an onsite or remote location. The footage is transferred to a computer or server for storage. Digital technology allows CCTV to be used for live security monitoring.
Digital provides faster retrieval, as you can rapidly search events by time, date, location and camera. You have options for archiving important information with your digital system, including HDD, CD-R, or DVD. You can also save space by setting your system to record only when motion or other pre-defined events are detected.
All digital surveillance technology provides higher resolution than analog. Within digital, there is also a difference in resolution. DVR’s provide a digital resolution of 1080, which we are all familiar with from our TVs. While this is an improvement from the pixilated analog video previously used, NVR-based systems have megapixel cameras which provide much clearer images which can show detail and have the ability to zoom in on facial details.
Technology End of Life
Low-definition analog systems are reaching the end of their lifespan due to competitively priced, better quality digital systems. It’s not just the camera quality either, digital systems provide better system back-up options and less maintenance.
Digital CCTV also have a longer lifespan as most systems have upgradeable software. However, DVR is being phased out for IP based systems. NVR systems have much higher resolution cameras and are now competitively priced with older cameras.
Don’t keep your security system in the past. Secure your people and assets with the most current technology available.
