CCTV has fast become a desired security system for homes with the ability to play back footage or view in real time on most smart phones anywhere in the world at any given time. It truly is the ultimate security gadget. With CCTV, like most things in life, there are a couple of points to consider before jumping in and buying a system.
Recorder: The DVR (Digital Video Recorder) or NVR (Network Video Recorder) is the part of the equipment that controls and records all footage. There are three main options to consider when deciding what DVR is best for you.
Image Quality This essentially comes down to what image quality you desire, for example IP systems will have a better image quality and are more aimed at the future however with most new technology costs are still high whereas analogue is tried and tested, provides great video image and is very reasonably priced.
Channel Size (how many cameras it can control) Unfortunately many people think "I only want one camera it can't be that much" however the DVR is the equipment you are investing in and they do not come in every size. The channel sizes are 4, 8, 16, 32 and 64 so if you only want one or two cameras at the front of a property you would still need a four channel DVR.
Storage This is the easy question, how long do you want to record for? We set our cameras up to record on motion detection so most customers get one to two months recording with four cameras. This factor mainly concerns commercial customers requiring 12 months plus of recording. However, it should be noted that with more cameras in place and recording there will be more storage requirements of the recorder.
Cameras: The options with cameras are less complicated as the concerning factors are image quality and appearance. The cameras we recommend are anti vandal day/night dome cameras as they are more subtle but still a visible deterrent as well as offering a clear image even at night.
