CCTV over IP

If you are looking to replace your existing Co-axial based CCTV system or time-lapse recording software. Or considering a completely new CCTV system for your office / building / factory we have the skills and expertise at hand to help bring your project to life. Not only do we have experience with voice and video quality our IT expertise allows us to implement extremely well designed and thought out security systems that encompass all the vital components of a CCTV system but can co-exist with existing IT infrastructures.

Advantages of IP over regular CCTV

The table below illustrates the main differences between the two camera technologies.

IP camera-based system Analogue camera based system
Access As open or closed access as needed. Remote access to live images and remote administration of a network camera are possible from anywhere using a standard Web browser on any PC. Closed circuit. No possibility for remote access.
Ease of use You can administer and view the images remotely using a standard Web browser on any PC.Images can be recorded on a hard disk, enabling easy search possibilities, easy storage and no image degradation or wear.The hard disk can be located at a remote location for security purposes. Remote administration or monitoring is not possible.Images must be stored on videotape cassettes, which require constant changing and lots of storage space. The quality of recorded images deteriorate over time.The video cassette recorder must be located near the camera. This could potentially enable unauthorized persons to have access to the videotape.
Quality A digital picture is created using Motion-JPEG. Once created, the image is free from degradation. Each frame within a video stream is sharp.Digital images do not lose quality in transmission or storage.MegaPixel cameras offer as much as 10 times the resolution whilst recording bigger areas. Images are digitised when used with DVR technology thus reducing noise and image picture degradation.Image quality is lost when using long cables and the resolution of a magnetic tape is normally quite low. In addition, the quality of the recorded video deteriorates over time.Analogue cameras correspond to just 4.0 mega pixels at DI or 4CIF.
System requirements Everything needed to stream live video over networks is included in the network camera. Simply connect the network camera to a network. View, record and administer from any networked PC (located anywhere). Connection to a coaxial cable, to a multiplexer, to a video or time lapse recorder, and to a locally placed CRT (cathode ray tube) monitor.
Installation Simply connect a network camera to the nearest network connection and assign an IP address. Attach a coax cable to each and every camera and connect to the multiplexer.
Scalability Adding more network cameras to the system is easy. Very difficult. Each analogue camera requires its own cable. Image quality is lost when using long cables.
Cabling One standard UTP (unshielded twisted pair) network cable can forward images from hundreds of network cameras simultaneously.

Integrated PTZ control and alarm transmission reduces telemetry, video and alarm cabling

One cable can transport video signals from only one camera at a time. If you have two cameras, you have to have two cables. This often means large cable trunks filled with thick and sensitive cables that are connected to a locally placed control room.
Cost A high quality network cable typically costs 30 to 40 percent less than a standard coaxial cable.A network cable can also support hundreds of network cameras and other devices.An IP-based network infrastructure is often already in place, which means the cost is reduced to that of the network camera(s).PoE reduces installation costs and provides benefit of power back up. Expensive coaxial cables. A classic RG59 75 Ohms coaxial cable typically costs 30 to 40 percent more than a high quality network cable.In addition, more cable is required. Each analogue camera requires its own cabling.High labour and maintenance demands, plus cost of the analogue camera(s), video tape recorder and videotape cassettes.
Security Secure encrypted video
Extras Integrated audio with lip syncIntelligence at the camera empowers a much more productive method of surveillance than analogue systems Not all analogue systems support audio
