Why you need to upgrade that DVR

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.

Better Video Surveillance: Upgrading is easier than you thought

Video surveillance is an integral part of any security plan.

It can be intimidating to upgrade technology, but upgrading your CCTV system is easier than you may think.  Network-based IP CCTV systems have become more affordable as the technology has become more common, so that now better quality video surveillance is cost-effective. If you haven’t upgraded your system to a Network-based IP CCTV system now may be the time.

Traditional CCTV Set-up

Traditional systems are arranged with cameras with a separate power source, and stored on a DVR. A DVR then converts the images to digital and broadcasts them on a monitor for instant viewing. The digital footage can also be sent out from the DVR, through a firewall/router and modem over the internet to remote devices for viewing.

Network-based IP CCTV Set-up

Unlike early digital cameras, IP cameras do not need a separate power source, they may derive their power from the same cable that transmits the video images. The signal is sent to a POE Switch (Power over Ethernet), and from their it can be delivered to multiple devices including a network video recorder (NVR) which does not have to be housed on-site and transmits the signal to monitors for immediate viewing, a local PC, and out, through a router/switch, and over the internet to remote devices for viewing.

The main differences here are: 1. the single cabling for power and video to the IP cameras, instead of separate cables required for power and video; and 2. No need to have an onsite storage device. This may not seem like much of a difference, but if your system is still based on older technology and you are worried about making the switch to newer and better technology, below are a few items to think about.

  1. Ease of Installation

A common misconception is that Network Video Recording-based installations are much more complex than DVR-based. While that may have been true in the past, advances in technology have included features like plug-and-play camera recognition which make NVR installations as simple as possible. New IP cameras also have ease of installation as a primary feature.

  1. Existing Infrastructure Use During Upgrade

If you have a CCTV system already in place, then you might want to transition your system slowly. There are solutions for this that will allow a slower migration so that you can replace components one at a time, either when they start to fail or have reached their end of life. This transition allows you to maximize your initial investments and provides the flexibility of funding your video surveillance upgrade over time.

  1. Cost-Effectiveness

As technology advances, IP cameras and NVR deployments are becoming more cost effective. The price of IP cameras continues to drop, and they provide significantly improved capabilities. The DVR is no longer cheaper to purchase, and the NVR operates as more than just storage – it can manage the video surveillance requirements while also operating as the foundation for the overall storage and data management needs for a work group, remote location, or stand-alone business.

  1. Scalability

If you are expanding your current CCTV system, utilizing IP cameras is the most logical choice to cover new areas. Network-IP cameras can be added to an installation that uses existing cameras. If you are expanding and ready to move away from the outdated technology of a DVR system, then this is a good place to start your system migration.

  1. Reliability

IP video surveillance systems have proven to be faster, more reliable, and every bit as durable as the older systems which utilize DVRs and analog cameras. When you consider all the inherent advantages of NVRs, the move to NVRs combined with IP cameras makes even more sense.
