Rapid advancement in computers has led to major changes in the security industry, such as the development of digital security systems. A digital security system makes retrieval of data more consistent and faster. Faster processors allow for faster frame rates. The frame rate of a digital security system is the number of frames/pictures a unit can record per second and are shared by the number of cameras. A digital security system uses a hard drive to store video to. A digital security system features far more advanced resolution.

Analogue security systems feature a VHS recorder, which is usually the lowest resolution part of the system. If a camera digital security system's camera has 480TVL- we want to be able to match that high resolution all the way through to the hard drive. The digital security system also archives video that holds up far better over time, it is virtually showing a new image everytime an image is played back. It is not likely to degrade over time. Somewhere along the line a analogue camera must present a digital image to be recorded, this is usually done by the recorder.

Many digital security systems use recorders that are designed to record video onto a hard drive or series of hard drives built into a machine. Storing this video directly to the hard drives, managing the files, images can be much less complicated because of built-in software in the digital security system. This is allows the digital security system to transfer video onto CD or DVD burners which can be networked by pc or externally attached. Some digital security systems have these built-in. When the hard drive on a digital security system becomes full, it starts to rewrite the oldest video first and record in a continuous loop.

Motion detection is also built-in to the digital security system and managed by the digital video recorder. A digital security system can email you upon motion detection and prompt you to remotely monitor. This is achieved by connecting the DVR to an Ethernet connection. Digital security systems are advancing rapidly and we pride ourselves on serving up the very latest digital security system technology available.
