Are you ever worried about your property whilst you are away from home, at work, on holiday or just out for a coffee? A modern and fairly discreet home CCTV system with remote access could be just the answer. View you property whilst at home or out and about via a remote computer or more simply via a smart phone (internet connection required).

A CCTV system can not only give you peace of mind that your property is being watched and recorded but is also an excellent visual deterrent for opportunist thieves and burglars who would notice the presence of cameras watching their every move and think twice about violating your property.

A typical home CCTV system could consist of a DVR unit (digital video recorder) or a NVR unit (network video recorder) and between 1 and eight cameras trained on the vulnerable and most significant areas of your property. Modern units record images on demand where clever software motion triggers activate the recording to a HDD (hard disk drive) and automatically overwrite the oldest previous events. This economical recoding method means you can rest assured that your CCTV system is recording the important activity and not simply hours and hours of nothing making it much simpler to view recorded events to pin down and view a particular incident should it happen.

So what is the difference between a DVR (digital video recorder) and a NVR (network video recorder)? Well the word digital in the case of the DVR refers to the recording medium being digitally compressed data usually recorded to a hard disk drive rather than the early CCTV system recordings being made to video tape. Although the recording element is digital the rest of the camera system in essence is analogue. There have been vast improvements in camera image sensor capabilities over the past few years with 1MP and 2MP (mega pixel) cameras giving the capability of 720P HD and 1080P full HD image quality recordings over the analogue transmission system. But progress hasn't stopped there. Further advances in image sensors giving 3MP and 4MP have gone past the physical capabilities of conventional analogue signal delivery systems. This is where network video recorders (NVRs) significantly come into play.

A NVR would be connected with IP (internet protocol) cameras and the camera's hardware processes and converts the image into data to then be transferred over a network cable or even via a wireless network bridge. As the data being carried can be compared to that of any digital media such a a DVD or even a data file downloaded or streamed the image quality capabilities are almost limitless only limited by the available bandwidth available and that of the image sensor in the camera itself.

Network video recorders function in a very similar way to their counterpart DVRs with a maximum number of connectable cameras, video output usually in a couple of formats (VGA and HDMI) and recordings being made to data storage. The biggest difference is how the cameras attach to the system, either via a network connection and / or by individual connections on the back of the unit. These connections are POE (power over ethernet) connections not only accepting the incoming data stream but also powering the IP cameras via the ethernet cabling to each camera. This type of versatile connectivity can lend itself perfectly to certain types of installation where the conventional analogue transmission system would be costly and particularly intrusive.

Naturally a more advanced NVR system with higher resolution recording ability does come with a higher price tag than a DVR system but at the point of installation consideration should be given to future upgrades with the correct cabling used.
