When you are seeking to integrate a home security system in your place of residence, it is important that you are aware of the different options and their respective advantages and disadvantages. One of the main distinctions between different security camera systems is the way in which the camera receives and transmits data to the server. This is especially important to consumers because of the effects it has upon the way the system works as a whole and the overall set-up process. As it turns out, there are two main categories of information transfer within the field of security surveillance. One is known as a closed circuit television system (commonly referred to as CCTV). The other is an internet camera, or IP camera system. Understanding the difference between these two categories will help you make your decision when it comes to which home security system you will end up purchasing.
When an individual or a business owns and operates a closed circuit television system, they utilize a system which is more traditional than an IP camera. These cameras transmit an analog signal to a specific, designated location. The footage recorded is broadcast to a limited set of monitors and―as the name would suggest―it runs on a closed circuit. Because of the bulky and archaic nature of these systems, they are not often employed in the area of home security. These cameras are most often seen put to use by large businesses that occupy a good deal of space, such as airports, casinos, and hotels. There have been a few advances in the industry which have lead to the integration of IP components in closed circuit systems, but even with these advances, they are still generally impractical for home use.
The Home Security Internet Camera
Like a closed circuit system, internet cameras (also known as Internet Protocol, or IP, cameras) transmit data to a specific location. But in the case of these systems, the difference occurs in the channels taken during this data transmission. When an IP camera records footage, it is most often directly routed to a home or business computer via the internet or wireless digital transfer through a computer system. Within this category of security cameras, there are two main sub-categories for consumers to consider. These categories include Centralized IP cameras and Decentralized IP cameras. Both have advantages and disadvantages that may cater to, or detract from, a user’s objective.
Centralized IP Systems
A centralized IP camera requires a separate component in order to record and manage the functions of the security system in conjunction with the camera. This additional component is known as a network video recorder (NVR). This part of the system is used to handle the recording and saving of security footage and manage the alarm systems.
Decentralized IP Systems
An IP camera which is part of a decentralized system does not require a separate network video recorder. These cameras come complete with all the necessary components to record and transfer the captured surveillance footage.
