Type, brand, affordability and quality are some of the features that are sought when purchasing Security Cameras. This is because of the many types of security cameras available in the market. Some of them are Infrared (IR) Monitoring Cameras, Dome Cameras, Pro Box Cameras, Pan Tilt Zoom Cameras, and Hidden Cameras. Then again there are analogue monitoring cameras and digital monitoring cameras. When buying a surveillance camera it is prudent to first decide what type of security system is sufficient to meet the objectives. This article briefly describes some of the aspects of each type to help in the selection. Infrared Security cameras can capture pictures in high resolution around the clock. They ideally capture motion in low light or in total darkness. They also can shift from colour focus to black and white. Furthermore, the infrared security cameras are not affected by hot or cold temperature without extra covers on them. They can produce clear pictures indoors irrespective of the lighting conditions where they are located. Dome Security Cameras are available in different styles. Some of them are infrared domes, outdoor domes, pan tilt zoom controllable domes, indoor domes and vandal proof domes. By setting a system of Smoked Dome Cameras, property owners can put unauthorized personnel who enter the place in real trouble, because these type of cameras are hardly visible to the human eye. On the other hand, pro box camera lens angles can be changed by users so as to get clearer views. They can switch from colour to black and white as the day progresses. They can also capture pictures in total darkness. But the infrared camera is more suitable for capturing pictures in total darkness than pro box cameras, which can take pictures more clearly at day time. Pan tilt zoom cameras can be controlled via DVR, joystick or remote controllers. They can rotate and focus on every direction and zoom pictures. They can be set to monitor one or certain areas. Large casinos, airports, super markets, and other similar places are fixed with this type of Security cameras because they can be set to operate in many ways. However, Pan Tilt Zoom Cameras are more expensive than other types. An additional cable called A CAT5 cable is needed with fixed Pan Tilt Zoom Cameras if they are to be controlled via the internet. Of the lot, hidden Security Cameras may be the most effective in surveillance. The categories of hidden camera locations include motion detectors, fake smoke detectors, sprinklers, clocks, EXIT signs and so on. However, in low light, the hidden camera picture quality is poor. Most of them are not weather proof as well. However, there are many advanced Security Cameras amongst the already mentioned types. Therefore, those who need to purchase Security Cameras should do so from reliable companies or agents. Even by looking at catalogues, buyers may not understand technical terms. This may lead to faulty installation of Security Cameras resulting in critical errors in the entire security system of the positions they are fixed.
