These security cameras are dome shaped & can be used for indoor and outdoor security applications. They can have IR LED's, a vari-focal lens, fixed lens, vandal rating which starts with IK, weather rating which starts with IP and they can have other functionality.
You usually see dome cameras in homes and where security needs to meet aesthetics. Domes are less obtrusive than bullet cameras or box cameras cased inside bulky housings. The dome disguises the direction the camera is pointed in, therefore the criminal won't know which way the camera is pointing.
These are vandal security cameras
This image above and to the left is a Nuvico Dome Camera. It has IR LED's & day/night functionality.
The next camera to the right is a cnb vandal dome camera with no IR LED's. If the camera has a low lux rating it will see in low light conditions. It will not however display video in pitch black. One major benefit of not have IR's is low power drain. This is providing power to a camera from distances over 350 ft. Whereas a camera with IR LED's will typically draw .5 amp to 1 amp, meaning it would have to be powered within 250-300 ft max.
The third camera on the right is a Nuvico vandal dome camera. This camera has flex pvc conduit going from camera to the weather proof box. Conduit is not necessary at every location.
These are indoor dome cameras-Typically when manufacturer writes indoor dome camera as part of the description that means it should only be used indoors. This is because it's not made to be outside, which means water and moisture will get inside and ultimately destroy the camera.
Flush Mount Dome- The first camera to the left is a flush mount camera. They look really nice when installed because only the dome and the white dome cover is exposed. The rest of the camera is above the tile/sheetrock. When installing these you have to cut out the sheetrock or the ceiling tile. Keep this in mind when ordering a flush mount dome camera.
The second camera is an indoor pelco camera with IR leds.
The third camera to the right is a Geovision indoor dome camera with no IR leds. The image below has this camera mounted to a drop ceiling during construction.
A dome camera can be an IP or an analog camera. A dome is simply the type or style of the camera. The camera can use a cat 5, cat 6 or an RG 59 cable. If the dome is an IP camera then it is usually ran on a cat 5, cat 6 or fiber, if it's an analog camera it is usually ran on an RG-59 Cable. For longer distances cat 5 or cat 6 would be recommended if you can power the camera close.
A dome camera can be installed on a ceiling or a wall depending on the camera itself. Some domes may only be mounted on a ceiling and not a wall. You must check the cameras axis gimble before purchasing the camera. It's up to the integrator to provide the right camera for the application. Most dome cameras have the option to come as "vandal proof" or "vandal resistant". This means the camera is more heavy duty, can take a rock or a hammer direct hit. The encasing is usually made out of a hardened acrylic plastic, allowing it to withstand rocks or other things thrown at it.
