What is a DVR System?

IP Surveillance Revolution

The IP Surveillance Revolution
The IP Surveillance Revolution Traditional analog surveillance technology (often referred to as Closed Circuit Television or simply CCTV) has now been around for over 20 years. Despite obvious deficiencies the functionality and price point for this basic technology has proven attractive and popular for use within security and industrial markets. However, with the recent introduction of IP Surveillance technology these industries and others can imminently expect to experience the benefits of a technical revolution.

What is IP Surveillance?
IP is the abbreviation for Internet Protocol, the most widely used protocol for communication over computer networks and the Internet. With 90 percent of today's networks now IP enabled, IP Surveillance technology is founded on a well proven yet future communication technology. It creates digitized video streams that are transferred via a computer network, enables remote monitoring as far away as the network reaches and enables viewing/monitoring from any remote location over the Internet. Its scalability makes it attractive not only for enhancing or revitalizing existing surveillance and remote monitoring applications, but makes it enticing for a vast number of new applications as well.

The True Cost of a System
In considering the relative merits of installing a completely new traditional analog surveillance system (CCTV) verses the development of a modern digital IP Surveillance system; the reasons for proceeding with the former remain few and far between. Because the choice between high resolution digital images that can be viewed and stored anywhere in the world over a computer network, against low resolution images with restricted viewing access and volatile storage media that deteriorates with age, becomes obvious very quickly. To arrive at the Total Cost of Ownership (TCO) for any system it is important to consider all of the affordable advantages and cost reductions over the expected life cycle for the system. Advantages and cost savers that are relevant to IP-Surveillance systems include:

  • Remote Accessibility - Improved access over an intranet or Internet provides quicker and more immediate access to digital quality images. Additional savings include reduced travel costs to and from the monitored site location. The images can be stored at remote locations (i.e. the Internet Camera Solutions server) for added security and convenience.
  • High Image Quality - Using digital cameras, processing, and storage means that picture quality will always be high. There is no degradation of image quality as when using analog equipment.
  • Simplified User Interface - The playback and search capabilities are far superior to those of analog systems, allowing users to instantly search and archive by events. Video alarm events can even be scheduled and immediately sent to any email receiving device for playback.
  • Lower Maintenance Costs - No need for swapping tapes since digital video is stored on hard disk. Because IP Surveillance systems include no moving parts, the repair and necessary service costs associated with analog tape drive systems are completely eliminated.
  • Future Proof - Your investment in IP-Surveillance is a long term investment. IP Surveillance is built on a technology which is quickly gaining recognition in the security industry. It also uses open standard protocols and networks for communication, which means that equipment from several manufacturers can be integrated in the same system. It also makes it possible to implement a larger IP Surveillance system step by step over time.
  • Cost Effective/Versatility - While IP-Surveillance systems can function independently, they can also work with any existing analog system. Through parallel connection, an IP-Surveillance system can be configured to receive the same video and alarm signaling as the resident analog system. With both systems capable of independent operation and no immediate need to dispose of functional legacy equipment, IP Surveillance technology offers a progressive step towards a digital imaging system without demand for huge installation and equipment costs.
  • Capacity For Integration - IP Surveillance technology has the capacity to be integrated into other functions and services within a continually developing system. Digital video feeds are easily distributed into other networked systems; such as access control systems, company intranets, alarm systems, etc.

DVR stands for Digital Video Recorder. View and Record 24 hour surveillance of your home or business from anywhere in the world.

DVR is a tool to record movies on a computer equipped with a video DVR card. It can record and compress data in real time, using recent codecs like MJPEG or MPEG4. DVR has a Graphical User Interface (GUI) in order to choose parameters of recording.

A DVR (Digital Video Recorder) which will work best for your needs depends on 2 factors

1) The # of cameras that you will need
2) The Frames Per Second (FPS) that you will need.

The Number Of Cameras That You Will Need

It is important to purchase a DVR system that will support the number of cameras that you will need now and in the near future.

The Frames Per Second (FPS)

As a benchmark, a television show is broadcasted at 30 FPS which provides crisp clean motion. In security systems a full 30 FPS is only necessary when you need to monitor close activity like a cash register where cash will be counted or in casinos where fast action is taking place. For example, a 4 camera system with 30 fps would give you about 7 fps per camera which is more then adequate for most security needs. With all of our units, you will be able to set the frame rate per camera.

DVR Systems

  • 16 CHANNEL DVR CAMERA SYSTEM (perfect for large home use or demanding business use.)
  • 8 CHANNEL DVR CAMERA SYSTEM (perfect for home or business use.)
  • 4 CHANNEL DVR CAMERA SYSTEM (perfect for home or light business use)

DVR Cards vs. Complete DVR unit

DVR cards are great if you have a spare computer that meets our System Specs and if you are capable of installing the unit and software on your own. It can save you money but will require time on your part to install and troubleshoot if needed.

The DVR complete factory built unit is simply a matter of plugging in the cameras and turning the unit on. If you are short on time and computer technical skills then the complete system is right for you.
