A qualified expert will also help you understand the confusing terms used to explain various technologies such as Analog and Digital systems. Others things that you should take into considerations at the onset of your project include how you want to use the data from the system and for how long you are going to keep it.

Analog CCTV system is the oldest technology in safety and security monitoring while Digital systems was developed to offer more benefits.


Understanding the Technology behind Analog CCTV System and Digital CCTV system

An Analog system basically records in the moment activity for future access as it does not allow viewing of actual live information and thus, not suitable for monitoring live activities. In most occasions, picture quality in analog systems is also of lower quality as compared to digital systems. With the digital CCTV systems, the camera views the scene and broadcasts it live to the server or computer through an internet connection. The actual capability of a digital system is based on the software used but most will record, display and transmit. Some advanced IP CCTV software allow advanced data analysis tasks to be done such as customized monitoring of a specific item.

It is also important to know that an IP CCTV System offers more intelligent data mining and information retrieval making it suitable for situations where security is an issue. An IP based system offers data encryption, which protects against image manipulation. The majority of the recent HD IP CCTV systems are also designed with in-built web servers eliminating the need for external servers and thus, improving security.

Simply, the major difference between IP based CCTV systems and Analog CCTV systems is the way in which video signal is transmitted. Analog systems turn video signal into a format that can be viewed on a monitor, television or a VCR. However, IP systems are able to digitize video signal using specialized encoder making it possible to view the captured details on the system network as well as on browsers through internet. However, it is necessary to remember that every system has its benefits and shortcomings.

Should you install an Analog or IP based CCTV System?
