Network Video Recorder (NVR)

Where Caution Blends with Technology!

A Network Video Recorder (NVR) is a digital device that sits on your IP CCTV network to receive live image/video streams and record them digitally to a hard disk.

An alternative to PC/server-based recording, the NVR offers a less complex installation, is easier to set up and has a user-friendly interface for day-to-day use. As the NVR is solely designed for IP CCTV surveillance, the embedded operating system is optimised to handle the maximum number of cameras the unit supports. This means that you can be confident that the NVR will be reliable, stable and perform as intended, unlike a PC/server based approach which has many variables that could affect performance.

Multi-site installations are simplified with the use of NVRs. If your organization spans multiple locations you can centralize the security monitoring to one location by linking an NVR at each location to managment software. Most NVRs today offer live video monitoring too and also allow remote access so a number of people can log in and view their cameras on the same machine simultaneously using secure logins.

What is a Security NVR?

Let’s first understand what an NVR is. A network video recorder popularly called NVR is a software program that enables recording surveillance video in a digital format to a disk drive, USB flash drive, memory card or other similar mass storage device. An NVR doesn’t have any dedicated video capturing hardware. However, the software uses a dedicated device, most often than not with an embedded operating system. Alternatively, in addition to help support increased functionality and serviceability, standard Windows operating systems and Linux are used with standard Intel processors and video management software. An NVR is typically deployed in an IP video surveillance system. NVR home security systems are generally wireless, they 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.

5MP HDCVI Security System
Each kit includes a security NVR, IP cameras, and all the accessories needed to run the security camera system. With a pre-installed HDD (hard disk drive), your recordings are stored locally on the NVR and are easy to access.
video converters

Converter Devices

Both IP or analog types of cameras work well in either commercial or residential security. IP cameras use UTP cabling (at least Cat5), and analog cameras can use either coax or UTP (at least Cat3). The video converters allow video from analog CCTV cameras and HD security cameras to be used on devices other than a surveillance DVR. For example, if you want to directly connect and display video from an analog camera on a VGA monitor, you can use a BNC to VGA converter. You can also connect an HD security camera (such as AHD, TVI, HD-SDI, or CVI) directly to an HDMI TV monitor by using an HDMI converter.
