Direct answer: If the resolution, mounting angle, location, and night lighting are suitable, existing cameras can theoretically be evaluated; however, since general-purpose security cameras usually lack the shutter speed, synchronized IR lighting, and optimized lens that LPR software requires, installing a dedicated ANPR (license plate recognition) camera is recommended for most sites.
Why are general cameras usually insufficient?
General-purpose CCTV cameras are designed to monitor a wide area; license plate recognition, on the other hand, requires capturing a narrow region (the plate area) with high detail and precise timing. These two needs create different optical and electronic requirements, so the assumption that "any camera can read plates" usually doesn't hold up on site.
Criteria checked for suitability
During the site survey, the following are evaluated: the camera's resolution density on the plate area (pixels per character), the mounting angle and distance, whether a shutter speed suitable for the vehicle speed can be set, whether synchronized IR support exists for nighttime use, and whether the camera has an output (IP/analog) that can feed a live image to the software.
Is partial use possible?
In some sites, an existing camera can be used with limited accuracy alongside an additional plate-recognition module or software; however, this is generally an interim solution preferred for low-traffic, non-critical points. For paid parking, corporate entrances, or security-sensitive points where high accuracy is expected, a purpose-built ANPR camera is recommended.

| General CCTV camera | Optimized for wide-area monitoring, usually insufficient for plates |
|---|---|
| ANPR (license plate recognition) camera | Optimized for the plate area, speed, and night conditions |
| Evaluation criteria | Resolution, angle, shutter speed, IR sync, output type |

Frequently asked questions
Can existing security cameras be used for license plate recognition?
They can be evaluated if resolution, angle, and location are suitable; suitability is examined technically during the site survey.
What is the difference between a general CCTV camera and an ANPR camera?
ANPR cameras are built specifically for plate reading with a high shutter speed, synchronized IR flash, and optimized lens; general CCTV cameras usually lack these features.
