Some CCTV systems extend over a very large property and may include a large number of cameras. This is done in order to have complete coverage of the property. This means that large and extensive cabling is required to connect the CCTV cameras to the monitoring and storage systems. It can be an expensive exercise to do this. You don’t only require the cabling, it will also take longer to install, and so the costs are passed onto you the consumer. If you want to monitor a large piece of land, then the easier option would be to get a wireless CCTV system. A wireless CCTV system requires fewer cables, hence there are fewer costs to be passed onto the consumer. It must be kept in mind, however, that wireless cameras are not entirely wireless. Most wireless cameras do require a power cable, so some cabling is required. A wireless system is more useful than your non-wireless systems as non-wireless systems sometimes have both a wireless cable as well as an ethernet cable. This makes it more difficult to install.
With some wireless cameras you do have the option of getting a battery powered version. And since these cameras are also wireless, a battery powered camera is a fully wireless option. The one drawback is that you will be required to change the batteries from time to time, which may be a hassle. But, if your cameras are carefully maintained this issue can be made easier to deal with.
Usually a wireless camera system will be bought in conjunction with a receiver. What happens is that the wireless camera will be setup in a certain location. Then a receiver will be placed in an appropriate location where it can receive the cameras signal. The receiver then sends its data to your storage and monitoring CCTV equipment. The signal which a wireless camera sends is a radio signal. So there is the potential for other appliances to interfere with the signal sending. Also, a wireless signal is better used in open spaces, or in areas where there is direct line of sight between camera and receiver.
