Analog security camera systems have had a stranglehold on residential and small business surveillance applications for many years. Users have cited various reasons for preferring analog over IP technology, including cost of equipment, installation and maintenance, as well scalability. These reasons could have been valid in the past, but with time, IP technology has advanced and made IP security systems the number one choice. Below is a comparison between these two technologies.
Analog vs. IP Security Systems
Initially, analog security camera systems were offered in pre-packaged camera and DVR kits. The kits were offered at different pricing levels, thus making them appealing to residential and small business clients. However, analog systems have no future. Therefore, investing in such systems will only offer a short-term cost saving, but end up being expensive in the future.
Technically speaking, analog technology is obsolete. For this reason, it makes no financial sense to invest in an analog security system, which will require replacement after a few years. IP technology on the other hand, has great prospects in the years to come, and thus guarantees homes and businesses future proof security solutions.
IP technology has a great impact, not just on security camera systems, but other business systems as well. Unlike the analog cameras, IP security cameras can integrate seamlessly with other modern systems, including access control and alarm systems.
Purchasing analog camera kits might have been cheaper many years back. However, the challenge with these kits came in when the need to expand the system arose. The size of the analog camera systems is determined by the number of channels (cameras) that the DVR supports, and is usually in multiples i.e. 4, 8, and 16 channels. IP based surveillance systems do not have this shortcoming. When time to expand comes, users can buy any number of IP security cameras for their surveillance system, starting with one camera.
Analog technology cannot support extended functionality such as remote access and viewing. IP security cameras enable users to access live surveillance video over the Internet, and using a wide variety of mobile devices.
