Both homes and businesses need to know how to protect themselves. Setting up a surveillance system is therefore important. If you are a business that has a lot of dealings with the public, such as a restaurant or a retail outlet, it is vital to make sure that you have some kind of CCTV system put in place. When it comes to surveillance systems, you will find that there are a lot of choices. A lot of the time, these security cameras will be hooked up to a central system via wires. However, wires cannot always reach all parts of you infrastructure. To counter this, wireless and outdoor cameras are available, and these can end up being a lot more efficient.
Why Use Wireless Cameras?
Wireless cameras are useful for a number of reasons. A wireless security camera can be placed almost anywhere. While you will sometimes have to use a wire for power, the “wireless” part means that information is sent through a radio band. There are cameras that you can get that will be powered by batteries, however. A lot of the time, these can be used at the likes of festivals where there is no power outlet to hook them up to. Both analog and digital wireless cameras exist. With digital wireless cameras, the transmission signals are encoded as digital packets over a specific bandwidth. There is also a wider transmission available. Quality of video and audio is also a lot higher.
For analog cameras, a transmission range of three hundred feet or ninety meters is available. Theoretically anyone with a wireless receiver can receive the signals. But wireless cameras and receivers have a number of security measures including encoding to ensure only the designated receiver is able to get and view the signals. Others receiving the signals will only see noise. Wireless transmission of video could be affected by other wireless signals in the atmosphere, but technology has advanced far enough to make this moot now. Wireless cameras, for short distances, can transmit very clear videos.
Using Outdoor Cameras
Outdoor cameras are frequently wireless and will often only have a cable that allows the transmission of power and energy. Outdoor cameras are also designed to be durable and withstand a wide range of different types of weather. If you plan on getting surveillance cameras for your home or your business then you need to take a look at whether or not it is water proof. Even if you do have some kind of shelter protecting the camera, you need to make sure that other forms of damage cannot occur. There is no telling what kind of elemental extremes may end up causing problems for your outdoor camera.
Useful Applications with Camera Systems & DVR
Wireless cameras, particularly those that rely on battery power, are more portable and versatile. While the recording time will be a lot shorter, you will be able to use analog and digital security cameras for a range of different purposes.
It is always a good idea to protect your business and this is one of the best ways of doing so. You will always be able to track those who come in and out of your property. You will also have something that can provide you with evidence should a court case happen to occur.
