Systems: 10 Mistakes that Most People Make

Important Information You Need to Know Before Buying CCTV Cameras

CCTV or Closed Circuit Television cameras are necessary tools installed in a specific area for monitoring. There are modern CCTV systems that consist of several parts used simultaneously for proper monitoring and detection, like DVR, cameras, hard disk drive, cables, monitor and power supply. Each of them play specific functions and you need to know each of them before buying your own system.

Digital Video Recorder (DVR) is regarded as the heart of the CCTV system. Available in various forms, it records, plays back and controls your cameras. Here are the common DVRs that you can select from.

The Full D1 is a type of DVR with the highest resolution to deliver among the many forms that you can find. Once you combine this with high specs CCTV cameras, you will certainly have the best CCTV system. It is commonly used for industrial purposes with tight security and settings where facial identification is vital. This one costs way higher than other types of DVRs, but the difference in picture with its counterparts is extremely minimal.

The Half D1 Half CIF is already good enough for small businesses or for environment that is not so tight. Nowadays, this is the most commonly used DVR as it is extremely affordable and offers high quality pictures. The name means that merely half of the number of installed cameras in the DVR can reach the maximum resolution while the other half can only manage to provide a lower resolution than the others. This is frequently chosen because of its less expensive price while still producing high quality images.

The CIF is an additional type of DVR but the disadvantage is that it produces the lowest quality among them all. This is already acceptable to some people, particularly to those who do not even notice the difference between various types. However, those who have background knowledge on CCTV systems or those who have very clear eyesight will definitely not pick this kind. It does not produce high quality pictures, knowing the price, so it is the most rarely used. Moreover, it is the oldest model as well of all the available DVRs in the market today.

On account of the availability of modern types of DVRs, recordings and play backs can already be extended to months rather than just days. The equipment can also be connected to the internet for easy access to your CCTV cameras even in remote places or from another location using your computer or mobile phones. Such convenient features can help people in appropriately running their business though they are not actually in the premises. The more sophisticated systems even comprise motion detection, power loss alarm, video loss alarm, manual and scheduled recording, and other options for extra protection and security.
