A dual-lens security camera is a new type of security camera that has two separate lenses to capture video and a great flash memory storing people’s counts’ data with 3D digital noise reduction. PRAMA India has a 2mm lens and a 4mm lens. In addition to the dual-lens, the camera also has two separate image sensors inside and they share the same Source. As the leading security solution provider PRAMA India’s dual-lens camera PT-NCX618PC with amazing features like dual CPU, support stereo views, Flash memory, people counting data, 3D digital noise reduction, and many more.

Dual lens security cameras are not panoramic cameras, because conventional panoramic cameras use either a fisheye lens to capture panoramic video or use more than 2 pieces of a lens to capture the panoramic view. A dual-lens security camera does not offer a panoramic view.

The dual-lens can help the camera to support optical zoom, this is a significant improvement over hardware, however digital zoom can not retain image quality and details. This disadvantage can be overcome by optical zoom.

Dual lens Vs Motorized zoom lens

As we know motorized zoom lenses also can provide optical zoom. Based on the mechanical optical structure has limited the zoom speed of motorized zoom lenses. In some AI functions such as face detection and face capturing, in order to capture the face in the video, the optical zoom should be super fast.

The dual-lens has two board lenses with a fixed focal length, the camera can switch between two sensors with super fast speed. Dual lens therefore can provide a fast zoom experience, also improve the performance of AI functions such as face detection, face capture, and pet recognition. The dual-lens camera is equipped with the new advanced technology and sensors providing you with an analysis of the most visited area in a particular time frame.
