ANPR (automatic number plate recognition) and LPR (license plate recognition) cameras are deployed in very different ways: fixed lanes, solar powered remote points, and temporary or mobile positions. Each deployment changes the camera requirements, power and network design, and reading accuracy you can expect. This guide compares the main ANPR and LPR camera deployment models.
Fixed deployment for lanes and gates
Fixed ANPR cameras are mounted over a specific lane, gate, or checkpoint where vehicles pass at a known speed and angle. They typically use mains power and a wired or local network, and they can be tuned for plate size, mounting height, and trigger zones. Fixed installations give the most consistent reads because the capture geometry does not change.
Solar and remote deployments
Solar powered LPR cameras bring plate reading to locations where no power or network exists: construction site gates, remote yards, temporary checkpoints, and mobile surveillance points. They combine an LPR camera with a solar panel, battery, and cellular link, so the unit is self-contained and can be relocated when the operation moves. Read accuracy still depends on correct mounting angle, distance, and lighting at each new location.
Mobile and temporary deployments
Mobile LPR systems are used by rental fleets, security teams, and events that change location frequently. A mobile unit may be a trailer or a pole-mounted camera with its own power. The key requirement is fast deployment and repeatable positioning, because the camera must be aimed correctly every time it is set up.

What affects read accuracy
- Mounting height and angle relative to the plate.
- Distance and vehicle speed at the capture point.
- Lighting and weather, including night and low-light operation.
- Camera resolution and lens selection for the lane width.
Choosing the model for your deployment
For fixed checkpoints, choose a dedicated ANPR model with the resolution and read-speed rating that matches your lane. For remote or changing sites, choose a solar powered LPR camera with cellular connectivity so the system is not tied to site power. SZGOING’s ANPR range covers both, from 3MP fixed units to solar capable models for remote monitoring, with integration outputs for barriers, displays, and access control systems.
Frequently asked questions
Can ANPR cameras work at night?
Yes, with suitable low-light or IR illumination. Lighting is a key part of deployment planning because plate reflectivity varies.
Do solar LPR cameras read plates as reliably as fixed units?
Solar units use the same recognition technology; reliability depends on correct mounting angle, distance, and lighting at the deployment point rather than the power source.
Can an LPR camera trigger barriers or alarms?
Yes. Many models provide plate-event outputs that can be connected to barriers, LED displays, and access control or video management software.
