Digital video recorders connect with video surveillance cameras, enabling you to record what the surveillance cameras see, and play it back at a later date. With remote viewing, all DVR security systems enable you to view security footage from a computer, your smart phone or tablet.

DVR security systems are available with 4 ,8and 16 channels, enabling you to connect up to 16 video surveillance cameras. Dependent on the DVR system these can record at night, outdoors and in HD quality.


CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features such as motion detection and email alerts.

More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.

Surveillance DVRs are designed for continuous operation as part of a 4-channel DVR, 8-channel DVR, and 16-channel DVR security system. All digital video recorder options feature H.264 compression and motion detection recording to maximize the amount of surveillance video you can store. They also feature multiplex operation so you can live view, record, play back, and back up your video simultaneously. Our security DVR recorders can be viewed remotely over the internet and via a free smart phone app so that you can keep an eye on your business or home from anywhere.

A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware. However, the software is typically run on a dedicated device, usually with an embedded operating system. Alternatively, to help support increased functionality and serviceability, standard Linux and Windows operating systems are used with standard Intel processors and video management software. An NVR is typically deployed in an IP video surveillance system. Network video recorders are distinct from digital video recorders (DVR) as their input is from a network rather than a direct connection to a video capture card or tuner. Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing.

Hybrid NVR/DVR security systems exist which incorporate functions of both NVR and DVR; these are considered a form of NVR.

NVR home security systems are generally wireless, tend to be easy to set up, can be accessed through a web browser, and allow the user to be notified by email if an alarm is triggered.

Video cameras are either analogue or Network, which means that they work on the basis of sending analogue or digital signals to a storage device such as a Digital Video recorder or servers.

Internet Protocol (IP Cameras) used by most Local Area Networks (LANs) to transmit video across data networks in digital form. IP can optionally be transmitted across the public internet, allowing users to view their cameras through any internet connection available through a computer or a3G phone. CCTV is used for, Monitoring, Crime Prevention, Industrial Process, Transport Safety, Control on retail, etc…
