TurretCam HL

Camera names may include the abbreviations HL, VF, and HLVF.

HL means hybrid light: the camera can switch between infrared (IR) and white LED illumination to capture color footage at night.

VF means varifocal: the camera is equipped with a lens that has a variable focal length, allowing users to adjust the focal distance and magnification.

If the camera name includes both HL and VF, it features both hybrid light and a varifocal lens.

The acronym DORI stands for Detection, Observation, Recognition, and Identification — standardized criteria that define the levels of detail a surveillance camera can provide at a specific distance, based on pixel density.

• Detection: The image quality is sufficient for detecting a person or vehicle within the scene.
• Observation: The image quality provides enough detail to observe characteristic features, such as clothing or shape.
• Recognition: The image quality is sufficient to recognize whether a person or vehicle in the image is someone or something the viewer has seen before.
• Identification: The image quality is sufficient to identify both the person and vehicles.
