There are two primary types of cameras used in video surveillance systems: analog and internet protocol (IP) cameras. Each camera operates differently. Many security camera systems are a hybrid system, incorporating both analog and digital components.
After you review the following attributes of each type of security camera, you may be able to determine which system is right for your needs.
Analog security cameras have been used in the security industry in CCTV systems for more than 30 years. Originally, analog cameras transmitted a signal via a cable to television and VCR, where the video was recorded on a tape to be watched later.
First developed in 1996, internet protocol (IP) security cameras capture and digitize analog images and has gained more popularity in recent years. The camera contains an encoder and a web server. Digital processing compression and motion detection also occurs within the camera.
It’s obvious from the above comparisons that the IP cameras are more robust, secure and reliable than the analog ones. You should weight whether you really need that level of security.
You’ll also need to weigh costs. An IP camera system is more expensive, especially the initial investment. But it's important to remember that a single IP camera can take the place of three or four comparable analog cameras due to the increased coverage area, so while a single unit may cost more, you're ultimately buying less cameras.
