Uniview 4MP LPR Bullet Camera, 2.8-12mm Varifocal Lens with IR and Warm Light
The Uniview 4MP LPR bullet camera is a dedicated licence plate recognition camera for vehicle monitoring and access control. It is built around a 4 megapixel image sensor and a varifocal lens with a focal length range of 2.8mm to 12mm. The varifocal design gives installers flexibility to set the viewing angle and distance so that number plates are captured clearly at the point where vehicles pass.

Why a varifocal LPR camera matters
Licence plate recognition depends on the plate being large enough in the image and sharp enough for the software to read the characters. A fixed lens forces the installer to choose one distance and one field of view. A varifocal lens such as the 2.8-12mm range covers a wider span of situations, so the same model can be set up for a narrow lane at close range or a wider entrance further away.
Infrared and lighting
The IR function allows the camera to capture images when ambient light is low, including at night. Infrared illumination is invisible to the human eye, so it does not dazzle drivers. The warm light version is the configuration named in this product listing. For the exact illumination distance, light colour behaviour and switching method, refer to the manufacturer’s documentation before installation.
Typical applications
- Car park entry and exit monitoring
- Gated residential and commercial access points
- Site perimeters and vehicle checkpoints
- Loading bays, depots and yards
- Roadside and traffic monitoring where plate capture is required
- Logging of vehicle movements for access or reporting purposes
Installation considerations
Mount the camera at a height and angle that gives a clear, near-frontal or slightly angled view of the number plates. Avoid pointing the lens directly into headlights or strong sunlight, as glare reduces plate readability. Setting the zoom and focus carefully during commissioning makes a large difference to recognition results. Ensure that the mounting location is stable so the view does not drift over time.
Working with LPR software
The camera captures the images, but plate reading is performed by LPR software, either on a server or on compatible devices. Confirm that the software you plan to use supports the camera model and the video stream settings you intend to use. Keep the camera network connection stable, as dropped streams can cause missed reads.
Who this camera suits
This model suits installers, system integrators and site managers who need a dedicated LPR camera for vehicle identification. It is less suited to general surveillance of people or open areas, where a standard CCTV camera with a wider field of view would be more appropriate.
