According to the functionalities, LPR cameras can be divided into 3 types.
License plate camera: it is the entry-level LPR camera that improves vehicle image quality and help users to manually view license plates in recorded videos. The lens and camera sensor are optimized to generate a very clear vehicle image including the license plate, it can also improve light conditions by equipping with white LEDs. But it does not support automatically license plate capture or recognition. It relies on NVR or VMS software to provide license plate recognition.
License plate capture camera: It will automatically capture license plates and save images locally or upload to cloud, but it does not support license plate recognition, so it will not record license plate numbers in the system. Users can be notified with clear vehicle images and read license plates manually. It does not support video search by license plate numbers.
License plate recognition camera: this is the most advanced LPR camera. It will not only capture license plate but also recognize the plate numbers and record into the system. It can be working indepedently, since the recognition software is built-in the camera. Users can define whitelist or blacklist database and set triggers when unauthorized vehicles are coming.
