Optical Zoom vs Digital Zoom
The video below is a good example of using both optical and digital zoom. It was made with a 3K camera equipped with a long-range optical zoom lens. The reason we can easily read the license plates is because the optical zoom lens was used to target a specific area about 40 feet wide where the vehicles plates consistently pass. Then after recording, digital zoom is was used to zoom into the 3K image allowing us to capture the plate.
How to Capture License Plates with Security Cameras
One of the most common requests our customers have is the ability to identify vehicles on or near their property. This can be achieved if you follow the rules and recommendations we detail below.
- Speed of the Car
The average speed that vehicles will be traveling is an important factor to consider when selecting the camera. It is best to select a targeted area that requires the car to reduce its speed as much as possible. If the car is traveling faster than 30mph, you will require a specialty license plate camera that has the ability to adjust shutter speeds so that the image does not blur. If the vehicle is traveling under 20mph, the task becomes much easier.
All of our ProVue IP and Cyber-Secure cameras have the ability to increase the shutter speed. This is needed if you plan on capturing plates at speeds above 20mph, for best performance increase the shutter speed as the vehicles speed increases. This will increase the clarity of any object at high speed.
- Camera Location
The location of the camera to the car's path is very important. If the camera is placed at too much of an angle from the plate's path, it will not produce the desired results. The best location for a camera is one that allows the camera to view the plate perpendicularly (as close to straight on as possible). The easy way to test the camera location is to simply park a car at the location you plan to capture plates, and then stand at the camera location. If you can clearly read the plate, the location should work.
- Dedicated Camera
The most common mistake made is to ask one camera to do the work of two or three. Often a customer will expect their camera to simultaneously view their driveway, see a person's face in a car and read the license plate. This is not possible. Each one of these tasks requires a different field of view (or focal length). Usually the camera is set to a wide viewing angle to see as much as possible, completely eliminating the ability to capture the detail needed to read a license plate. So here is the Golden Rule: One camera must be dedicated to ONLY reading license plates! This will allow you to adjust the field of view specifically for this task, assuring success.
- Glare
At night, cameras have the difficult job of balancing between the darkness and the intense lights of an oncoming car. The solution for capturing plates at night is to have the ability to adjust the cameras built-in WDR (Wide Dynamic Range), backlighting and image options. The cameras have backlighting adjustments which eliminates the glare. Most HD cameras can easily capture plates during the day, but there is no guarantee of successfully capturing plates at night.
- Selecting the Right Camera
There are two distances that matter when choosing the right camera for your application:
A) The distance from the camera location to the location you expect to capture the plate
B) The horizontal viewing distance at the location of the plate
Both distances can be accommodated by using a camera with a manual or motorized zoom lens. The manual zoom allows you to mount the camera and then zoom the camera's field of view in or out until the maximum horizontal distance is achieved.
As the chart below indicates, using a 2.8 to 12mm lens will allow you to mount the camera 60 feet away from the plate location and still achieve a horizontal field of view of 18 feet.
The green chart below indicates lens viewing distances.
The following MAXIMUM horizontal distances should be followed for best performance:
Cameras Mounts
Certain camera mounting locations require a back box or mounting box when the cable connections cannot be protected from the weather or tampering. This usually occurs when mounting to brick, concrete or poles. Anywhere you need to protect the cable connections.
We recommend ordering a back box for any outdoor location if you have not verified the cable connections will be protected. The boxes can be returned for a full refund if they are not needed. Not sending the back box with the initial install kit can mean a 3-5 day hold on installation as a mounting box is sent out to the site of the system. Interior cameras usually do not need a box because the cable connections can be pushed up above a ceiling or back into a wall and the camera mounted directly over the hole.
Most cameras have specific mounting box options. The boxes are not included with cameras but offered as an add-on option. If you are using one of the few cameras without an assigned mounting box, we recommend using our patented product, the M5 Universal Camera Mount. This unit supports any outdoor camera installation. Installers love them because they solve several problems that are common with other mounting boxes.
While the M5 is a superb product we still recommend using the factory mounting box provided for the camera. There are several ways to locate the correct box for each camera. The video below explains.
Below is a reference chart for the mounts available for the Cyber Secure Cameras.
