Anyone who has spent much time in the aisles of a department store will surely recognize the standard dome camera. This ceiling-mounted surveillance camera can move 360 degrees, tilting, panning, and zooming to provide a comprehensive view of the area. "Dome cameras" themselves are not actually shaped like a dome, but are so named because they are housed in a rounded plastic bubble, which makes it impossible for those in the store to see where the lens is looking at a given time.
The dome camera is one of the most popular security camera styles in use today. Using cameras for surveillance is commonplace in retail stores and other public businesses, and also has many applications outside of this environment. If you're looking for round-the-clock surveillance for your home, for example, you might want to consider a dome camera.
While many are designed for commercial applications, there are also many other styles that are appropriate for home use. Those on a budget, whether homeowners or business owners, may opt for a dummy dome camera. This device takes advantage of the dome style to trick passerby into believing that there is a camera watching them, when in reality it is the opaque dome with no cameras or electronics inside. This option looks just like the real thing, but does not transmit a recording and is less expensive than installing a real surveillance camera. Because these cameras operate on the idea that if potential criminals can't see where the camera is pointed, they will avoid the area, it makes no difference whether the camera inside is pointed towards them or there isn't even a real camera there at all.
Nowadays, it is not uncommon to find dummy or real dome cameras mounted in a wide array of environments. In addition to their traditional uses inside shopping malls, large stores, government buildings, banks, hospitals, and other public places, dome cameras may also be seen mounted on nearly any other flat surface, for example to watch activities in your backyard. The surveillance camera can be installed on the ceiling or on a wall. Some models even offer different dome color options to better blend in with the surroundings. While most dome cameras are hard-wired into the building, today more and more surveillance systems can be accessed wirelessly.
If you are purchasing a dome camera, consider its use and where it will be installed before choosing a camera. Dome cameras have a wide variety of ranges and styles; make sure that the camera you choose has a wide enough range to see activities in the surrounding areas. Compare pan, tilt, and zoom capabilities to find a camera capable of covering all angles. These features may be abbreviated as PTZ. A stationery dome camera may be a good choice for those looking to protect a relatively small area with a small budget, while those that can rotate and zoom are better for covering larger spaces. Installation should be planned carefully to ensure that the camera offers the views you need.
There are styles designed for use during the day, such as most retail surveillance cameras, in addition to cameras with infrared or night vision for more specialized uses. Look for one with a sturdy case that will withstand the efforts of vandals. A secure covering is particularly important when the camera is to be installed outdoors, where it may be subjected to the elements.
