In the past, the main surveillance systems seemed to be the closed circuit television system, that broadcast its signal in analog format. The signals did not reach that far, and the images would have to be recorded, and then watched at a later date on a video recorder. This was not only a pain, but images were not in real time. This system was fine as long as you were in the house, however, how about when you are away?

Over recent years, the internet has brought us many new, and exciting technologies, one of which being the ability to watch our house, through a webcam, via the internet 24 hours a day, seven days a week as long as you have a connection. Movements in your house can be sent, via the internet, to your laptop for you to watch in real time.

With home surveillance you have the option of having cameras in numerous rooms and can watch the images all at the same time, and recently, more and more companies have installed digital surveillance to cut down on theft and vandalism.

Nowadays, the are several surveillance packages available or, indeed, you may want to build your own. When buying your cameras it is important that they are discreet and blend in with the surroundings as much as possible and most importantly of all do not cut on cost. The more you spend the clearer the images will be.

If you are creating your own surveillance system, then there is various software available, that can alert you by phone, email or text when an intruder enters your home, which is very helpful if you are out of the house for a long time and unable to access the internet.

Unlike the old analog videos, these days images recorded in a digital format are much more defined and retain their quality however many times they are played back. Compressing the files also enables you to save and file them much easier than a pile of video tapes.

There are many advantages to digital surveillance systems and these days systems are relatively inexpensive and simple to install and operate.
