There are plenty of CCTV systems in the market; technological advances have resulted in significant price reductions which have made them affordable to a wider market segment. But not all CCTV systems are the same. While the current trend is to switch to IP video technology, many companies are still doing well using analog surveillance systems. CCTV systems are also being used to deter criminals in public areas.
Comparing The Benefits And Drawbacks of Analog Surveillance Systems
Some companies who already have analog cameras and recording equipment may hesitate to transition to IP video equipment. Others who may opt for analog equipment may be on tight budgets; analog equipments are significantly less expensive. For the most part, one should not dismiss analog camera systems outright. In fact, with the right digital video recorders you should still be able to use analog cameras while migrating to digital surveillance systems.
Aside from lower cost, analog CCTV systems capture images better in low light conditions; this is an area where digital cameras are still in the process of catching up. Using analog surveillance systems, it is also easier to mix and match different camera, recording and surveillance equipment from different manufacturers.
Among the weaknesses of analog CCTV systems is the use expensive cabling which is hard to install and sometimes poses maintenance problems as well. Many new features of digital systems such as video analytics, digital zoom, and higher resolutions are not offered by comparable analog CCTV systems.
That said, if you have a small facility to cover, and you are on a tight budget, an analog CCTV system might not be such a bad idea. But for larger applications you may have to go digital.
Choosing Components Wisely
Cameras are available in a wide variety of resolutions. If you need to identify people involved in the incidents you are monitoring, you will need high definition (HD) video cameras. The lenses installed on cameras also differ in terms of viewing angle, which starts at about 20 degrees up to more than 90 degrees. There are also cameras whose views can be manipulated. These are known as pan tilt and zoom (PTZ) cameras. For deployment at outdoor locations you may want to cameras which are weather proof. For monitoring dark areas, there are video surveillance cameras with low light capabilities.
There are several types of camera mountings such as tubular, dome type, and multiple camera pods which cover as many as four directions at once.
For recording equipment there are DVR’s and even tapes you may choose from. There is even an option of having a security company monitor your security and store video surveillance footages offsite, sometimes direct to a secure cloud-based server.
Monitors can be any type of screen, although at least a flat screen is recommended. The size of the monitor would depend on the number of camera footages you want to view at the same time. And the best option, mainly for ease of use, is an interactive screen.
Whether you use the latest technology or just the simplest CCTV system, the most important consideration is always whether you get adequate protection from perceived threats. And that varies from one situation to the next.
