After you have decided on the installation location of the doorbell security system, you can choose the type of camera design. There are several types of construction. Let’s take a look at them and find out which type is more suitable for your video surveillance system.
Cylindrical chamber
The barrel chamber is easy to install and set up without the need to open the chamber. Also, when the camera is properly installed, there are no wires left outside that could be cut by vandals, because the wires are led to the camera inside the holder. The directionality of most bullet cameras is easy to manually adjust once the camera is installed thanks to the movable 3-axis mount. The adaptive view makes these cameras ideal for outdoor installations and surveillance from long distances. Compared to domes, bullet cameras offer stronger optical zoom and more powerful IR for night vision.
Dome camera
The dome camera is more difficult to install, but due to its non-demonstrative design, this camera will be an ideal solution for a home or restaurant. The dome shape does not allow you to immediately determine where the camera is directed. To correctly adjust the lens position of the dome camera, you need to open it. While it can be assumed that dome cameras are primarily designed for indoor installations, many of these cameras are also vandal and weather resistant. If the camera is installed correctly, the wires are hidden. Already installed dome cameras are difficult to remove and rearrange to another location. In the fixed focus segment, dome cameras typically offer wide-angle lenses that provide a larger field of view. If you need an unobtrusive security camera, especially for your home, then a dome camera is ideal. At the same time, it is wrong to assess the degree of suitability of a video surveillance camera for outdoor use by the type of execution – cylindrical or domed. It depends on the level of climate protection of a particular camera model.
Dome camera with turret lens
Turret cameras, also called eyeball cameras, combine the advantages of dome and bullet cameras. The Eyeball camera lens can be mounted at almost any angle, just like a bullet camera, while the turret camera is as compact and vandal resistant as the dome camera. Consider turret cameras if you’re looking for a discreet, vandal-proof camera that’s easy to point in almost any direction, just like a bullet camera.
Pan/tilt zoom camera (PTZ)
The angle of the video recorded on the PTZ camera (Pan – pan, Tilt – tilt, Zoom – zoom) in real time can be adjusted by changing the direction (in azimuth and elevation) and the focal length of the lens. This is done using a control joystick, NVR or even from a smartphone. PTZ cameras are more expensive than other types of cameras, but they offer more features.
The PTZ camera can be switched to the scanning mode, which allows you to conduct dynamic video surveillance according to a given pattern. Some PTZ cameras have the function of automatically tracking objects entering a certain area. Consider a PTZ camera if you are going to actively monitor a large area, such as a parking lot, in real time with the ability to increase the level of detail using optical zoom.
Conclusion
After reading about all the specs and types of security cameras, make sure you choose the right ones accordingly as per your need.
