“The lens is measured in focal length (mm or angle). PTZ cameras are dome-shaped and allow the user to remotely control the camera so it can pan, tilt and zoom in/out, providing an effective means for surveillance.Īccording to a recent blogpost by Kintronics, a PTZ camera’s lens zoom and resolution are important factors to consider. Dome cameras are more vandal-resistant as well.
Like bullet cameras, dome cameras’ field of view cannot be changed however the direction the camera is pointing to is typically not immediately noticeable, and this can be an advantage. Unlike bullet cameras, they are more low-profile and offer a more discreet way of keeping premises under surveillance. Capable of easily blending into a facility’s internal environment, they are usually placed inside on a ceiling, although they can also be attached directly to a wall. However they may not be as vandal-proof as the other types, so placing them at less reachable places may be ideal.ĭome cameras are so named due to their dome-shaped body. Additional benefits include easier installation and cheaper prices, compared to domes and PTZs. They are typically indiscreet in the way they are installed, and as a result they serve as an effective visual deterrent for criminals. They have a fixed or variable focal length and point at one direction at a time so they can be useful in targeting a specific area of the property. Before purchasing an IP camera, though, several things need to be considered, including which type – bullet, dome or PTZ – to get.īullet cameras are shaped exactly like a bullet. Needless to say, security cameras are more and more moving towards IP, which carries various benefits, including higher resolution, integration with other IP systems and ease of installation using PoE where both data and power are delivered.
Understanding their benefits and limitations, therefore, is important in helping the user decide which one to choose. The primary ones are bullet, dome and PTZ which can be confusing to users.
