Outdoor surveillance cameras are the most important part in a home security system as it is equally important in business security. Outdoor surveillance cameras are different from the indoor cameras in many ways. The indoor cameras are competitively having low covering range and mostly work in bright lighting condition. This may be little different if we are talking about commercial indoor use; however, they all have the same goal.
On the other hand, the outdoor surveillance cameras have to cover a larger space in most cases. They have to have a powerful lens to capture every single details as well as every face that crosses the path. To get the best use, many features are installed with these cameras. First of all, these cameras are designed to capture better video and audio signal and transmit it to a distance. Both wired and wireless cameras can be used, but the first one cost much less than the later one. The recording quality is good enough to detect the face or other evidence in case of any invasion. Nowadays, this technology has become digital and the recording video is saved in hard disk at first and later in a compact disk.
A very important fact about the outdoor surveillance cameras is they are usable in both day and night. Many cameras come with an infrared feature that allows them to keep monitoring at night in low lighting condition or even without having any lights on at all. Some even have a motion detector and can monitor the movements of the intruder. In some high quality camera, you may find the feature where the camera can zoom itself to capture the face and activities more clearly if they detect any illegal entrance.
Because of their exposure state and outdoor service, these cameras need to be placed in a secure place where it can be safe from water, dust, strong sunray or any other natural disturbance. If it’s a wired camera, you have to make sure that the wires can have easy path and does not have any vulnerability to an outside person who can just cut it to stop the surveillance. In the wired security cameras, walls or trees can put obstacles in transferring the data to the recording room. So you need to place them in such location that there is nothing between the camera and the signal receiver. The controlling of the camera must be excellent and the user should be able to control the camera any way he wishes. For example, the on and off feature, zoom option, panning or tilting etc. should be done from the control room.
