Why Digital Cctv?
When setting up a CCTV system for your property or your business there are many different options and things to consider and this can sometimes make it hard to choose just one CCTV system out of the large selection.
The majority of people looking to install cameras in their property no matter what the nature of that property is, will be looking for digital cameras. There are many reasons that people gravitate towards digital cameras, and these include the fact that they are higher definition both temporal and spacial meaning that they have more pixels for a crisper image and they have a higher frame rate. A digital CCTV system will also be preferable for most people as the data it saves goes directly to a memory card or to online storage and this then means that it doesn’t have to be physically ‘stored’ such as that data kept on a VHS (which you get with analogue cameras). Perhaps most importantly of all, a digital CCTV system allows you to record from multiple ‘tracks’ or that’s multiple cameras simultaneously. This then makes you far less likely to miss any important action through recording from the wrong camera at the time anything happens.
At the same time, a digital CCTV camera can benefit from many other functions and additional bells and whistles. This is because the data is digital meaning that it can be manipulated in a number of ways. With a motion sensor for instance you can ensure that you don’t waste space recording static footage, whereas with video analysis you can make sure that you only record when there is human activity being picked up. These are highly useful as they allow you to record much less footage which not only saves memory on your storage device, but also means that you won’t have half as much footage to sift through in order to see if anything happened during the night. This also then means that you can tie your CCTV system in to your other security such as an alarm. This way you can then trigger the alarm to sound when human-looking movement is picked up on the camera.
Using an IP CCTV system (Internet Protocol) you can even broadcast the footage across a wireless connection to be watched remotely. Further more, using VoIP (Voice Internet Protocol) you can even set it to record sound and transmit it so that you can ask who’s there when your alarm sounds without having to actually be present in the room. Here you have almost achieved omnipresence…
Another benefit of IP CCTV is the fact that it doesn’t need wires. The fact that it uses a wireless internet connection means that there is no call for cables running through the walls or suspended ceiling which of course is a great advantage allowing you to place the cameras wherever you want them without restrictions and meaning that you can move them quickly and easily without having electrical contractors come around and dig out the insulation in your walls.
