Wireless Security Camera

Cameras are an effective way of maintaining security in a remote location. While they are small and inexpensive, installing cables for them can be very expensive. Wireless security cameras get around this problem by using radio signals instead of cables. There are infrared models that can see in the dark and small pinhole models that are difficult to detect. Affordable packages containing everything required to setup a wireless camera system are available from most retailers that sell consumer electronics.

Wireless security cameras can be easily identified by the small aerial sticking up at the back of them. Typically, each cameras is powered by a nine volt battery, but some models can also be powered by an adapter plugged into a nearby wall socket. Outdoor models have a sealed housing that is waterproof and corrosion resistant. Infrared models are surrounded by rings of tiny infrared lights that turn on automatically when the ambient light level drops.

The main reason to buy wireless security cameras is to avoid the trouble and expense of installing cables. The cables often have to be run through walls, roof spaces, and wall cavities. It is a lot of hard work to install them yourself and it costs a lot of money to pay someone to install them. The cables can also be run along the insides of a building, but this looks very unattractive and is not really suitable for a home. Wireless cameras can also be quickly moved to another location, something that takes a while to do for wired cameras.

Wireless security cameras can be divided into two groups. One group is the infrared cameras that are mounted on a bracket, out in the open for everyone to see. These are used for monitoring a particular spot in all lighting conditions. The other group are the pinhole cameras that are concealed from view and can only see when there is light. They are used for covert surveillance, when it is legally permissible to do so. Both groups of cameras have several features in common.

The technology used by wireless security cameras to send video and audio back to a receiver is based on the same technology used in cordless phones and notebook computers. It has a range of about 100 feet indoors but can reach nearly 300 feet outdoors, when there are no walls or other obstacles in the way. It is important not to mount the cameras on or near metal objects because this can disrupt their signals. A switching receiver can be used to show the views from up to four cameras, by quickly cycling through the signals from the cameras.

There are several important features to look for when choosing wireless security cameras. They should have a high resolution and a wide angle coverage, and the infrared cameras should have a good range in the dark. The cameras should also be energy efficient so that their batteries last longer. Outdoor cameras must be able to operate in all weather conditions and not be affected by extreme heat or cold. An adjustable bracket is useful for when the cameras need to be pointed in another direction.

There is a wide range of options for purchasing wireless security cameras. There are packages that include just one camera and a receiver, as well as packages that have many cameras. Each package contains everything required to setup the cameras, including mounting brackets and screws for the larger cameras. Some packages even contain a handheld monitor that is powered by a rechargeable battery. Finally, it should be noted that pinhole cameras may need some work done to the building structure to properly conceal them from view.
