Frequently Asked
Questions

Metrici is a 100% Romanian software solution. It was at first a license plate recognition solution and now it integrated many more offers and features addressing parking lots, transport businesses, retails, industrial parks, local authorities, police etc. We are also specialist in custom AI projects where we train DNN models to recognize any object or situation a client needs.

Our basic solution is specially meant for this type of installation. One can have special attention when setting the features of the software, e.g time to ignore a license plate when viewed twice.

Metrici LPR can work with any type of IP cameras, but for best results, we recommend using specialized IP cameras designed for license plate recognition.

No, you don't. When we talk about camera designed for LPR, we refer to camera with the technical characteristics for LPR. There is no need for LPR on camera. However if you have such a camera, you can use it with Metrici, not a problem whatsoever.

No, it doesn't. The software is an artificial intelligence example that can adapt itself to many situations but has limitations. There are standards for placing the detection cameras so as not to affect the quality of the recognition. Also the quality of the hardware used can compromise the detection. Please read the manual for best installation.

Metrici LPR can work with any access control gates and can command any type of device for an action.

See section case studies and inspire from there. Only your imagination can be the limit of where to use this software solution. Besides the installation already made, one can use this solution for car counting, clients awarding, employee tracking (time spent on the route), traffic flow, data management.

License plate recognition systems (LPRs) use optical character recognition (OCR) algorithms to allow computer software to read vehicle license plates. The systems are also known as automatic license plate recognition systems, or ALPR, automatic number plate recognition ANPR.

Go to downloads section of our support site and see the last saved version, download and install it.

This is a security feature. Once a camera began recording events it can no longer be deleted from the interface.

Check if you added camera to locations. Have you noticed the authkey and ID generated? Fill them in Metrici Control Panel camera settings. See the manual for better understanding.

Check if you have set a detection window and if the number is inside that window, check the dimension of the plates. Is the image focused? Is the fps right for your scenario?

Are you having enough bandwidth? Check and change.

First of all, you should consult the manual and read it carefully. It has all the information needed to operate successfully this software solution. If you continue having problems, please write us with the specific troubles you have. We periodically give training to integrators.

The best solution for you is to contact one of our distributors. They will be able to offer you a personalized offer depending on the complexity of your installation and location. As for installation you can find all the useful data in user guides.

Read the manual regarding the camera. For best results, the camera should not have an inclination of no more than 20 degrees from the vertical/horizontal.

More explanations can be found in the detailed user guides in section downloads.

Car license plate numbers size must not be less than 200 px. Or generally speaking, a car must take up at least 1/3 of the total area of the screen. Truck - at least 1/2.

This feature depends on camera settings and capabilities. The most important are the focus and shutter speed. With a good camera and a good placement, detection is possible at even 250 km/h. But the key here is a good camera placement and settings, otherwise you will have distorted images even if the car is parked. For this please read the manual regarding camera settings.

We are always ready for the client wishes and many of today's features were introduced at clients' requests.

Yes. The system is working properly even at night with proper IR or illumination.

Metrici works under Linux. Starting with version 4.0 from February 2026, Metrici works on Ubuntu.

You can find this information in datasheets, in download section. The requirement depends on number of cameras used. As a general rule, Metrici requires a GPU in the latest developments.

No. The license is only for one computer. In case of reinstallation you will need another license key.

By purchasing the program, you will grant access to all the upgrades that will be released within 1 year from your purchase. After this time the updates will cost 10 percent of the price of the acquisition program.

Whilst CCTV cameras can record events, they are not designed to capture specific information for any given setting. LPR cameras are designed to read and capture number plates at varying distances and then refer that information back to a software system. Generally, LPR cameras are meant specifically for this type of monitoring. As we stated before, no need for dedicated LPR on-camera.

The system does not take photos of the driver and does not record such data.

These type of cameras are a niche market and require higher pricing because of their additional features.

As we stated, the latest developments require a dedicated video card for using Metrici. If you acquired the servers from Metrici, most certainly you will have one installed.

Our software systems require tight contact between the end-user and the direct installer of the product.

Due to the fact that most users are not experienced IT-sector specialists, many of them experience a large number of questions connected with the initial installation and set-up of the program software and integration with the hardware: cameras, loops, triggers, lasers, Infrared lighting, sensors, cables and many more.

In order to increase the satisfaction of our end-users, we deploy a network of regional partners.

In general, the weakness of the License plate recognition comes from the technical issues and settings and not from the software itself. In ideal condition of installation, detection rate comes close to 100%. But there are weaknesses that tend to undermine their effectiveness. Some of these include poor resolution of the captured images because of the quality of the cameras used or the distance of the vehicle; blurry images because of high speed motion; lighting or contrast problems because of shadows, overexposure and reflections; obstruction in the line of sight of the camera such as other vehicles, a tow bar or dirt in the plate itself;

Metrici LPR special software can overcome most of these problems, but this is why one needs to pay special attention when installing the system

The system is designed around data protection: all data is stored in your own infrastructure — locally or in your own cloud — and never on Metrici servers. The system does not take photos of drivers and does not record such data.

No. Metrici can be deployed on your own local server or in the cloud, depending on your infrastructure and needs. In either case, the data stays under your control.

Yes. The web interface is responsive and can be accessed from any device connected to the network.

The number depends on the server hardware. All cameras and locations can be managed from a single interface.

Yes — unlimited number of locations, with reports per camera, per zone or for the entire location.

Yes. Metrici supports license plates from many countries, with dedicated syntax and optimized recognition for each one — including EU, UK and other international formats, with the list growing with every release.

Vehicles (make, model, color, class), people, boats, parking occupancy, area and line counting, container codes, QR codes, temperature (thermal), red light infringement, speeding — and custom objects for special projects.

Yes. Vehicle classification covers car, SUV, van, bus, small truck, big truck, tram and utility vehicle.

Yes — access control and barriers, payment machines, VMS platforms, LED displays and third party software via API. Many integrations are built on request.

Yes — request a live demo of any Metrici solution and our team will show the software on your use case.

Our network of regional partners handles installation and on-site support, with full documentation and user guides provided.
