LPR cameras: what are they?
Specialized security cameras called license plate recognition (LPR) cameras are made to recognize, record, and identify license plates on moving automobiles. With the use of this in-demand function that can detect, and scan license plates, users or law enforcement may rapidly identify any car on the scene. The technology is known by various names: License Plate Recognition (LPR), Automatic Number Plate Recognition (ANPR), Automated License Plate Readers (ALPR), and Number Plate Recognition (NPR). Regardless of the name, it is evident that this powerful tool is something many should consider integrating into their video surveillance systems.

LPR cameras are used where?

• Parking lots are the most common application for LPR cameras; thus, it makes sense. This is the first area you should keep an eye on since this is where the majority of the onsite cars will be arriving, parked, and leaving each day.
• Toll booths and gates: These are additional locations where video surveillance ought to be installed already. LPR capability only serves to increase safety and provides a better means of reviewing and comprehending issues when they may emerge. This technology can also be used by local and state authorities to detect infractions and automate the process of making amends.
• Drive-through businesses should always have security cameras in place in case of an incident and having license plate recognition guarantees you have additional information to review and, if needed, give to the police.
• Car Washes: Of course, one of the many small companies that can profit from having LPR cameras on site is car washes. In addition to improving security, having a better grasp of who is coming and exiting may open up new possibilities for determining customer frequency and amount of time spent on site.
• Parking garages are a natural location for strategic deployment because they meet the same requirements as parking lots. Here is where it’s important to maintain constant watch over who enters and exits your building.
• Gates and Entry Stations: You may obtain most of the information you require about which vehicles have entered a site by just keeping an eye on the points of entry and departure. When looking into a normal event, the records generated here, which include times and plate numbers, can be all you need.
• Stop and Go Traffic Areas: Any area where there is stop-and-go traffic is a good candidate for LPR-capable device monitoring. Such environments might provide issues due to their dynamic patterns; it may be helpful to have identifiable data while investigating an incident.

What are some LPR camera installation considerations?

When installing LPR cameras, it is important to consider the following: the number of lanes the camera will cover, the appropriate lens for the desired recognition distance, the installation height and pitch angle, the angle between the vehicle’s direction and the camera, and the pixel requirements for plate and vehicle recognition. Additionally, ensure the camera is focused and zoomed in on the target area, and consider combining LPR cameras with regular Day/Night mode cameras for optimal effectiveness.

• Location: For effectiveness, license plate reader cameras ought to be situated in areas with high vehicle traffic. Ideal locations are choke points such as entrances to parking lots, junctions, and one-way streets, where vehicles pass slowly through a set point. A property survey is necessary prior to installation to identify these optimal choke points.
• Dimensions: Cameras should be mounted at an optimal height and distance from the vehicles. Typically, mounting them approximately 5 meters above the ground and angling them at 30 degrees towards the designated choke point is advisable. However, conducting tests to verify the accuracy of the setup is essential.
• Settings: Contemporary LPR cameras are equipped with specialized software that aids business and property owners in customizing settings to match their specific installation needs. These settings typically encompass exposure, zoom, and focus, with the possibility of additional features such as specialized day and night modes. It is crucial to adjust and rigorously test these features before they are put into regular operation.
• Maintenance: It is crucial for stakeholders to acknowledge that plate reader cameras require regular assessment and upkeep. Accordingly, these units should be positioned where staff can safely reach the physical hardware, yet hidden to minimize the risk of vandalism. In certain cases, it may be beneficial to opt for LPR cameras equipped with anti-vandalism features such as tamper-resistant lens covers and pressure alarms.
