Analog Vs IP Security Camera Systems – What’s the Difference?

A CCTV system allows you to monitor activity on-site, and can be used as both a surveillance tool and as a method of identifying and prosecuting thieves. But when it comes to choosing the type of system it can become a little confusing. This blog highlights the main differences between the camera systems:

What is an Analog Security Camera System?

The analog cameras are the more traditional systems of the two, they capture an analogue video signal and transfer that signal over coax or UTP cabling back to the digital recorder (DVR). The DVR converts the analog signal to digital, compresses it, and then stores it on a hard drive for when the video is required. Most modern DVRs can be accessed remotely from LAN, or with the proper configuration, from across the WAN or internet and can add password protection and other features. When broadcasting over the internet, the video for all of the cameras is transmitted as one stream (one IP address). Therefore, it is very efficient. There are no tapes to change as the video is kept on the hard drives, typically on a FIFO basis so there is always a rolling video archive of the pas x number of days.

What is an IP Security Camera System?

IP stands for Internet Protocol and refers to a digital video camera that can send and receive data via a computer network, as opposed to sending a feed to a DVR. Each network camera captures an analog image but immediately converts it to digital inside the camera. The digital video stream is broadcast over the local area network (LAN) using Ethernet cable. The Ethernet cable for each camera is plugged into the switch which feeds into the network hub. Video footabge is stored on new or existing network RAID drives as directed by the network video recorder (NVR) software.

IP systems offer high resolution images and are currently available above 5 mega pixels, whereas analog cameras max out on a resolution at about 580 TVL which equates to about 0.4 mega pixels.

What is a Hybrid Camera System?

This system is a combination of both IP and analog video. It can be a good was to transition an analog system to IP without the need of new cameras. A lot of the NVR boxes are in fact hybrid as they work with analog cameras and IP cameras and then combine them on to a single platform for the user.

The Verdict

Although IP systems are likely to be more expensive, they are worth it. The video is of a much higher resolution making it a more powerful system. The ability to digitally zoom in on recorded video makes identification easier.
