Differences between Analog and IP Cameras

Businesses that are looking to implement surveillance camera systems have to select between the analog cameras and IP security cameras.
In making a choice, one must consider the benefits of each system, such as its functionality and price. This also helps in determining the suitability of a system, with regard to the individual business needs.

Understanding Analog vs. IP Surveillance Technology

Analog security cameras capture video in traditional baseband format. The analog signal is then transmitted through coax cabling to the video recording system, which might consist of either time-lapse VCR-based recorders or DVRs.

IP security cameras on the other hand, come with powerful video processing software, which enable them to capture analog video and convert it internally to digital video formats. The digital signal is then transmitted down UTP cabling to network video recorders, for storage on network drives or viewing in real time.

The Advantages of IP Surveillance Systems


In the past, analog security camera systems were the obvious choice for both homes and businesses. However, the introduction of IP surveillance systems has seen analog technology become obsolete. Below is a look at how these two security camera systems differ.

Hardware: IP surveillance systems enable users to discard most of the outdated hardware such as time-lapse recorders, CCTV monitors, and switching units, and replace them with the powerful software-based NVRs.

High Resolution: IP security cameras offer sharp, crisp video images, as compared to analog systems. This is because IP Cameras capture and immediately, convert the video into a digital stream before transmission. The digital signal ensures that the quality of video doesn't degrade with time or distance.

Remote Viewing Capability: IP technology allows users to view surveillance video from any geographical location. Each security camera is treated as an independent network device, with a unique IP address. As such, users can access individual cameras from within their local network, or over the internet.

Future-proof Investment: Investing in an analog camera system is a waste of resources since the technology is already obsolete. IP surveillance systems on the other hand, are largely software based. As such, the software can be upgraded easily from time to time
