Significant Information You Ought to Know Ahead of Buying CCTV Cameras

CCTV or Closed Circuit Television cameras are important tools installed in a certain 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 have specific functions and you have to know each of them prior to buying your own system.

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

The Full D1 is a kind of DVR with the highest resolution to offer among the many types that you can find. When you combine this with high specs CCTV cameras, you will absolutely have the best CCTV system. It is frequently used for industrial purposes with strict 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 acceptable for small businesses or for environment that is not so strict. These days, this is the most commonly used DVR because it is extremely affordable and offers high quality pictures. The name indicates that just 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 usually preferred because of its cheaper 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, especially to those who do not even notice the difference between several 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.

Because of the availability of modern types of DVRs, recordings and play backs can already be extended to months instead of just days. The equipment can be connected also to the internet for easy access to your CCTV cameras even in far-flung places or from another location using your computer or mobile phones. Such convenient features can help people in running their business properly even 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.
