Types of Security Cameras
Security cameras come in various types, each with its own set of features and capabilities. Some common types of security cameras include:
1. Dome Cameras
Dome cameras are named for their dome-shaped housing, which makes it difficult for intruders to determine where the camera is pointing. These cameras are commonly used in indoor settings.
2. Bullet Cameras
Bullet cameras are long and cylindrical in shape, resembling a bullet. They are typically used for outdoor surveillance and have a long-range view.
Other types of security cameras include PTZ cameras, wireless cameras, and thermal cameras, each serving specific surveillance needs.
Facial Detection vs. Facial Recognition
Facial detection and facial recognition are two distinct technologies used in security cameras and other surveillance systems.
Facial detection refers to the ability of a camera to detect the presence of a human face in a video feed. It is a basic feature that allows the camera to recognize that a face is present in the frame.
Facial recognition, on the other hand, takes facial detection a step further by identifying and verifying the identity of the person detected. This technology matches the detected face with a database of known faces to determine if the person is a known individual.
| Facial Detection | Facial Recognition |
|---|---|
| Recognizes the presence of a face | Identifies and verifies the identity of the person |
| Basic feature | Advanced technology |
| Used for general surveillance | Used for access control and security purposes |
