License Plate & Vehicle Surveillance
How to Choose a License Plate Recognition Camera
A general security camera and a license plate recognition camera do not necessarily perform the same job. General cameras are usually positioned to provide broad situational awareness. LPR cameras are selected and positioned specifically to capture vehicle license plates within a defined area.
Successful plate capture depends on more than camera resolution. Vehicle speed, camera distance, viewing angle, lane width, lens selection, mounting height and available lighting all affect results. For that reason, planning the installation is especially important when choosing an LPR system.
What Is a License Plate Recognition Camera?
A license plate camera is a specialized surveillance camera designed to capture readable images of vehicle license plates. These cameras are commonly called LPR cameras, license plate recognition cameras or license plate capture cameras.
Some compatible systems may also provide additional license-plate-related search or analytics capabilities, depending on the specific camera, recorder and software being used.
LPR vs. Standard Security Cameras
License Plate Cameras
Designed around a specific vehicle capture zone where the primary goal is obtaining useful plate detail as vehicles pass through the monitored area.
General Security Cameras
Designed primarily for broader surveillance of people, activity, buildings, parking areas and property rather than a dedicated plate capture zone.
Best Locations for License Plate Cameras
Driveway Entrances
Capture vehicles entering or leaving a residential or commercial property.
Parking Lots
Monitor defined vehicle lanes rather than trying to capture every plate from a distant overview camera.
Gates
Controlled access points can provide predictable vehicle speed and positioning.
Commercial Entrances
Record vehicle activity entering warehouses, businesses, campuses and other controlled properties.
Camera Angle Matters for License Plate Capture
The camera should be aimed toward a defined section of roadway or driveway where vehicles predictably pass. Extremely steep horizontal or vertical angles can make plate capture more difficult because the plate appears distorted or occupies fewer usable pixels within the image.
A well-designed LPR installation generally focuses the camera on a narrower capture zone rather than using the camera as a wide-area overview. A separate general security camera can be used when broader vehicle context is also required.
Vehicle Speed and LPR Camera Performance
Vehicle speed is another major consideration. Capturing a slowly moving vehicle at a gate or driveway can be very different from capturing a vehicle traveling quickly through a road or large commercial entrance.
Choose the camera and installation design according to the expected speed and distance of the vehicles being monitored rather than assuming one camera configuration will work equally well in every environment.
License Plate Cameras for Day and Night
License plates can be difficult to capture after dark because headlights, reflective plate material and changing outdoor lighting can create challenging exposure conditions. A camera designed for vehicle and plate capture can be configured to prioritize the plate area rather than the overall brightness of the scene.
Nighttime performance varies by camera and installation, which makes camera distance, lens selection and lighting conditions especially important.
PoE License Plate Recognition Cameras
A PoE license plate camera uses IP networking and compatible Power over Ethernet infrastructure. Ethernet can provide network connectivity and power to compatible cameras, helping simplify installation and provide a wired connection to the surveillance network.
PoE LPR cameras are especially useful when license plate surveillance needs to be integrated with a larger professional IP security camera system.

Record License Plate Cameras to an NVR
Compatible IP license plate cameras can record locally to a network video recorder along with your other surveillance cameras. This gives the system one central location for video storage, playback and camera management.
Using local NVR storage also allows standard surveillance recording without requiring a monthly cloud-storage subscription.

Use LPR Cameras with Other Security Cameras
The strongest vehicle surveillance design often uses an LPR camera together with one or more general security cameras. The LPR camera focuses on capturing the plate, while a wider camera records the vehicle, occupants and surrounding activity.
This approach provides both identification detail and situational context without forcing one camera to perform two very different jobs.

License Plate Recognition Camera FAQs
What is an LPR camera?
An LPR camera is a specialized security camera designed to capture useful images of vehicle license plates within a defined surveillance area.
Is an LPR camera different from a normal security camera?
Yes. General security cameras are usually intended for broad surveillance, while an LPR camera is optimized around a specific vehicle and plate capture location.
Can license plate cameras work at night?
Yes, compatible LPR cameras can be used at night, but performance depends on the camera, vehicle distance, speed, angle and lighting conditions.
Where should an LPR camera be installed?
Good locations include gates, driveway entrances, parking-lot exits and other areas where vehicles pass through a predictable capture zone.
Can LPR cameras record to an NVR?
Compatible IP license plate cameras can record locally to an NVR along with other compatible security cameras.
Do license plate camera systems require monthly fees?
A system that records locally to an NVR can store standard surveillance video without requiring a monthly cloud-storage subscription.
Should I use a second camera with an LPR camera?
Often yes. An LPR camera can focus on the plate while a second overview camera records the vehicle and surrounding activity.
