An Overview Of CCTV Security Systems
Thursday, August 25th, 2011Ensuring the security of any property be it a commercial or residential building, has never been so important. With police funding being slashed, and disorder on the streets rising, the importance of comprehensive CCTV systems has never been so great. If you are planning to invest in a number of surveillance cameras, it is important to know how to choose the right designs.
First of all, you should assess your actual needs. Before you invest any money, you need to consider such factors as what should be monitored, whether cameras need to be installed indoors and out, how many cameras would be required, what type of technology should be used, and the actual area or space that needs to be monitored. Only through a careful needs analysis would you be able to ensure that your money is spent constructively as opposed to being wasted.
The technology that is used in CCTV surveillance cameras has evolved considerably over the years. Whereas a decade ago, most systems were wired, today there is the option of wireless designs, as well as cameras that can be connected to a local area network or even the Internet. The latter are the latest options. They have a dedicated network IP address that allows them to be hooked up to a home or business router and accessed remotely.
The cheapest option would be a wired system, but these are also the easiest to tamper with. Wireless systems are easy to install, as they do not require any cabling to be used, they are flexible and can be repositioned to get the maximum coverage as and when needs dictate. When checking out various products, make a note of whether they are powered by mains electric or battery, this would have a bearing on where they are used.
Another important consideration is the resolution of the camera. The higher the resolution, the more detailed and focused the images will be. Today, the cost of high resolution cameras has come down in price, it makes sense to spend slightly more on a camera with a good resolution as these would be able to provide a clear image of anyone involved in dubious activity.
If the system is to be used in a business setting, it can be of value to opt for cameras that can be panned, tilted, and zoomed. Such features can provide the optimum deterrent as they can cover a large area, and also focus in on an individual who is behaving suspiciously. A camera that has the ability to pan, tilt, and zoom can be identified by the acronym PTZ.
On a final note, if you want to install a camera outdoors, opt for a design specifically made for this purpose. It should be both tamper proof and weather proof. There is the option of choosing a hidden camera, though retail establishments rather than homeowners mostly use these cameras.
As long as you compare a number of different designs, you should not have too much difficulty in choosing a CCTV security system that does enhance the security of your building. Savings in property insurance can often recoup the cost of the equipment and the installation.
