Security Camera Systems - IP Vs Analog
CCTV security cameras have come a long way since being first introduced into the market in the late 1960's. There are all types of CCTV cameras now such as dome cameras, bullet cameras, IR cameras that can see in the dark and even tiny little pen cameras like the James Bond. The security camera industry has become one of the fastest growing industries in recent years since September 11th. Analog and IP cameras are the two types of CCTV cameras available currently on the market. And while though analog CCTV cameras are still the most widely used type, the features and flexibility that consumers & businesses can gain by using IP CCTV systems versus analog are immense. Some features include, cameras that run on power over Ethernet (POE).
What this means is that the camera can be powered and transfer video feed all with one Cat5 cable, rather than running a power cable and a separate video cable the way that analog cameras do. Another perk of using IP CCTV cameras is that the resolution that can be achieved far surpasses the video quality that can be delivered while using analog technology. IP cameras resolution is measured in digital megapixels instead of TV Lines (TVL) as traditional analog cameras do. What this means to the consumers is a sharper, crisper, and more detailed picture than what is achieved with analog. With the launch of IP cameras there came another method of recoding and storing footage taken by CCTV systems. The Digital Video Recorder also known as a DVR is used to take footage or video taken by a security camera and storing it as the name says, digitally, onto a hard drive.
Now owners can view up to a month's worth of footage on a DVR without having to change old VHS tapes for certain days as was done in the past. IP cameras also known as Internet Protocol cameras use Network Video Recorders to record footage which can then be viewed remotely from anywhere that has an internet signal. Currently people can even view a CCTV feed via their internet enabled smart phones, with this feature consumers can have more freedom and a better sense of security knowing they can view their CCTV system anywhere. But with all the perks that IP CCTV camera technology can deliver there is a downside; because IP technology is still new to the industry the cost of installing an IP security system is still significantly higher than going with an Analog CCTV System. With the rate of how quickly technology improves in today's age, analog cameras are still very capable of delivering the convenience, safety, and security that consumers have come to expect at a lower cost than IP.
The surveillance industry has even given the convince that comes with the IP CCTV security system to analog users by allowing them to also view their systems remotely from any computer or smart phone. In the end there are pros and cons with either analog or IP systems, but when it all comes down do it, not every CCTV security camera system's application is the same for every consumer. So using the power of the world wide web, one should look for what type of system is best suited for the application at hand. If not then it could end up costing more than what is really needed for the situation, and who really wants to pay more something especially something that won't be used.
