What Is a License Plate Recognition (LPR) Camera? What Are Its Benefits?

Nowadays, technology in every field is advancing by leaps and bounds, and security is no exception. Most people are already familiar with CCTV cameras installed to record footage of various events, but today another cutting-edge innovation deserves recognition: the license plate reading camera, or LPR camera. For anyone wondering what an LPR system, or License Plate Recognition camera, actually is and how useful it can be, let's explore the details together.

What Is a License Plate Recognition (LPR) Camera?

A license plate reading camera, or LPR camera, is a type of CCTV camera developed primarily to function as a license plate reading program. It works together with computer software for analysis and an automatic entry-exit barrier system to read license plates and open/close the entry and exit gates of housing estates as well as various buildings, greatly improving convenience, speed, and security. It can read and record data for both cars and motorcycles, covering standard white plates with black characters, auction plates, red plates, yellow plates, and green plates, as long as they were issued by the Department of Land Transport. This license plate reading camera can operate with an accuracy level of 95-98%.

How Does a License Plate Recognition (LPR) System Work?

The license plate recognition camera system, or LPR, stands for License Plate Recognition, meaning a camera that reads vehicle license plates. It is another highly interesting technology. The way the LPR system, or license plate detection system, works is as follows: when a car or motorcycle drives up in front of the entry-exit barrier, the camera automatically captures an image of the vehicle and identifies the position of the license plate, then forwards it to the installed program for analysis, evaluation, and data extraction using Optical Character

Recognition (OCR) technology, which is a system for recognizing characters through light, converting them into numbers, categories, letters, and province, right down to the vehicle's make and color. This greatly facilitates the use of vehicle entry-exit data for other purposes as well.

In cases where the camera works together with the entry-exit barrier, once the license plate reading program has finished analyzing, evaluating, and extracting the data, the barrier will be raised immediately, within no more than 3-5 seconds. However, this system usually requires the vehicle to be pre-registered with the project or the security service provider in question, such as being a resident of the housing estate or an employee working in the office building. Visitors go through the same system as well.

In addition, here is a bit more information about using the LPR license plate detection system. In cases where the camera encounters a license plate that is faded, peeling, damaged, or has numbers or letters that are not visible, has gold plating or stickers covering it, or uses a counterfeit plate that was not legally issued by the Department of Land Transport, the camera will not be able to read that license plate.

What Are the Benefits of a License Plate Recognition (LPR) Camera?

Now that you know how a license plate detection camera system works, let's summarize the great benefits that everyone gains from choosing to use an LPR camera, making it easier to decide whether to install one for your own project or to choose a property management company whose services include an LPR system. Let's take a look.

• 1. Convenience for everyone involved

  A license plate reading camera creates convenience for both vehicle drivers and security staff by being a fully automated system. Analysis, evaluation, and approval of data take no more than 5 seconds, and the driver can simply continue driving through. This means staff no longer need to bother exchanging cards or manually raising the entry barrier.

• 2. Greatly enhances security for the location

  A license plate reading camera helps raise the level of security for a given area, especially in places that require a high degree of privacy, such as housing estates and condominiums, because only vehicles that have been specifically registered are allowed through. In addition, if the camera detects a fake license plate or plate cloning, it will issue an alert and will not allow that vehicle to pass.

• 3. Recorded data can be used for other purposes

  The data captured by the license plate reading camera, or LPR, can also be used for other purposes, such as serving as evidence for police officers, or as statistics indicating peak periods of vehicle entry and exit so that more staff can be scheduled during those shifts. Users can also download this data as an Excel file or a PDF file.

• 4. Usable at all times, with high accuracy

  An LPR camera can be used at all hours, both day and night, thanks to its WDR lens, which effectively enhances image clarity, as well as its ability to see through headlights and taillights, ensuring clear recording in every situation regardless of the time of day. On top of that, its clarity and accuracy level remain very high, averaging 95-98%.

• 5. Can be used together with other devices

  Besides functioning as a camera for detecting license plates, a license plate reading camera can also work together with other devices, further enhancing modernity, convenience, and speed. Examples include entry-exit barriers (as described above), parking fee calculation systems, and parking duration recording systems.

How Should a License Plate Recognition (LPR) Camera Be Installed, and What Locations Is It Suitable For?

For anyone interested in installing a license plate reading CCTV camera, these days LPR cameras are not expensive at all. You can choose a quality brand, such as the Hikvision license plate reading camera, for excellent performance. That said, here are the key principles for installation.

• Mount the camera at a level where the license plate and the entire vehicle can be clearly seen

  In case the driver's face needs to be used as evidence, or other additional vehicle details such as make, model, and color are needed, this camera height will help capture complete data on every vehicle excellently.

• Connect the system to the security guard booth so staff can provide additional oversight

  In the event of something unexpected, such as the camera being unable to read a faded license plate, security staff can manually open or close the entry-exit barrier to keep things moving, or check that vehicle for anything unusual.

• Always install it in front of the barrier, on the side the vehicle will pass through

  Nothing should ever be allowed to obstruct the camera's range, to ensure that images are captured accurately and precisely, preventing problems or incorrect data recording later on.

Many people may still have further questions about what kinds of locations this license plate reading camera should be installed at. Simply put, it can be installed at virtually any location with parking, whether that's a condominium, housing estate, hotel, mall, hospital, government office, office building, private parking lot, factory, or other locations, as long as there is a parking area or a clearly supervised parking spot.

An LPR system, or license plate reading camera system, is a technology that can capture the license plate image of every vehicle passing through a designated area and store the data for later verification. Nowadays, license plate reading cameras are very affordably priced and are not difficult to install.
