Digital CCTV, or Digital Closed Circuit Television, is the technology used in modern surveillance systems. Modern Digital CCTV Systems can be operated on site or remotely via a pc or mobile phone, can monitor various locations and can be monitored from wherever there is internet or GPRS Access. Currently the majority of CCTV systems use Digital technology. Digital CCTV Surveillance uses current PC technology to digitise the CCTV camera images and compress them into a PC friendly format. These digital images can then be stored onto a standard PC Hard Disk Drive.
As the digital CCTV images are stored onto a PC Hard Drive it is possible to store digital footage and access it speedily and easily using a LAN/WAN connection or remotely over broadband using a PC or Mobile Phone.
We specialise in the installation of sophisticated network digital recording systems with audio capability and an internal DVD/CD-RW Writer. The Hard Disc Drive(s) can record images either continuously, by alarm trigger or via VMD, (video motion detection). Email notification upon motion detection is just one of the many features possible.
Each Camera input record rate (frames per second) can be individually programmable and you can search for data by means of event, location or time/date simply by the click of a button. Each PC connected upon an internal LAN connection can view the CCTV Cameras and retrieve data. Connections are password protected and logged for added security.
Digital CCTV Video Recorders, (DVR), are stand-alone units that are capable of saving analogue CCTV Camera inputs to internal HDD storage.
Typically, up to 32 Analogue CCTV Cameras are connected to the back of the unit via standard CCTV Camera connection referred to as BNC. By connecting a CCTV Monitor to the DVR you are able to view your CCTV Cameras in different screen divisions (single camera, 2×2, 3×3 etc) and also playback footage at the click of a mouse. Our DVR’s & NVR’s allow you to view live and retrieve previous recordings from anywhere in the world using a PC, Tablet or Mobile Phone.
Almost all DVR’s now have built in VMD, Motion Detection Technology. This means that digital footage is only recorded when someone or something walks/moves in front of your CCTV Camera.
HD stands for High Definition, and SDI stands for Serial Digital Interface – a family of standardised, broadcast quality digital interfaces using BNC connectors.
Because of its origins in broadcast, the definition and picture quality of HD-SDI footage is noticeably higher than a standard analogue signal. Because it has been designed with the sole purpose of providing Megapixel, High Definition footage over standard co-ax cable, it is perfectly suited to CCTV, where the majority of existing systems use RG59 Coaxial Cable.
HD-SDI DVR’s typically have all the benefits of Analogue DVR’s but can easily be used in tandem with existing analogue & HD cameras.
IP based cameras are the future and offer high definition images starting at 1.3 Mega Pixel upwards depending on your budget. They work by turning images and audio into data then transmitting this data over a network or Internet connection. The ultimate benefit of this over analogue CCTV systems is greater flexibility, better performance and easier installation. Whilst IP CCTV has been available for over 10 years now, it is only in the last few years that the technology has matured, leading to the developments in Megapixel IP and due to demand, reduced in cost.
IP CCTV systems communicate using IP, allowing them to integrate and co-exist on the same network/cabling as other IP based systems, such as Access Control and IP Phone Systems etc… Integration also means that these different systems can work together, for example an IP camera picking up movement will be able to transmit images of that movement to an IP Video Phone automatically. IP systems also allow the direct use of IP-based services as standard such as e-mail or image sending via FTP.
CCTV Remote View & Playback
We can network your existing ADSL Router for Remote CCTV Viewing via the Internet using a PC, Laptop or Mobile 3/4G device.
Our current range of Analogue, HD DVR’s & IP NVR’s allow you to not only remotely monitor your CCTV Cameras, but also playback previous recordings, from anywhere in the world. Take Snapshots or Video Clips of the remote playback and email on to a third party all from your PC, Laptop or Mobile 3/4G device.
You do NOT require a static IP address with our range of DVR & NVR’s as we will configure your connection through our Dynamic DNS Server.
