Turning On Vehicle Recognition

Vehicle recognition is off by default. When it is on, vehicles and license plates are recognized on every camera in the place.

Caution: license plates are processed With vehicle recognition on, the plate number, a photo, and an appearance signature are stored for every vehicle the cameras capture. This data is stored only on the device.

A plate number becomes personal data when combined with other information such as a name (Korea PIPA, GDPR, and others). Signage, use limited to the stated purpose, and retention limits are required, and automated plate recognition is restricted or prohibited in some regions. You are responsible for verifying and complying with the regulations that apply at the installation site.

On the Settings tab, click the Vehicle recognition row.
Turn on the switch at the top. A license plate processing notice is shown.
Review the notice and click Agree and turn on.
If needed, choose values for the settings below. The defaults work for most sites.
Click Save on the save bar at the bottom of the screen.

The Vehicle recognition screen in Settings — Settings > Vehicle recognition. While the switch is on, the detection and plate recognition settings are shown.

Setting	What it does	When to change
Detection accuracy	The precision of the analysis that finds people and vehicles.	Accurate when the device has headroom
Threshold	How confident detection must be to count an object as a vehicle.	Strict if things that are not vehicles are detected
Plate type	The format of the plates to read.	Korean plates in Korea, International plates anywhere else
Plate recognition accuracy	The precision of the analysis that reads plates. Higher precision puts more load on the device.	Accurate if plates are often misread
Plate threshold	How confident the reading must be to be accepted as a plate number.	Strict if many plates are misread, Loose to read blurry plates too
Registered plate matching	How closely a read plate must match a registered plate.	Exact match if other vehicles are mistaken for registered ones

Note Detection accuracy shares its value with person recognition; changing it on one screen changes it on the other. With vehicle recognition on, Vehicles appears on the History tab and the Registry tab appears in the sidebar (in the tab bar at the bottom on a phone).

Options and defaults for each setting

Detection accuracy: Fast, Balanced (default), or Accurate.
Threshold: Loose, Normal (default), or Strict.
Plate type: Korean plates or International plates (A–Z, 0–9). The default depends on the display language (Korean plates when the language is Korean).
Plate recognition accuracy: Fast (default) or Accurate.
Plate threshold: Loose, Normal (default), or Strict.
Registered plate matching: Up to 1 character off (default) or Exact match. With the default, a registered vehicle is still recognized when one character is misread.

Which plates each plate type can read

Korean plates reads these formats:

Single-row plates with 7 characters (e.g. 12가3456) or 8 characters (e.g. 123가4567)
Commercial plates (e.g. 11바9876) and electric vehicle plates
Older plates that start with a region name (e.g. 서울12가3456)
Two-row plates (e.g. 경기28바5489)

International plates (A–Z, 0–9) reads plate numbers made of capital letters A to Z and digits 0 to 9, up to 10 characters. Characters in other scripts, such as Arabic or Thai, are left out of the plate number.

It uses an open model (fast-plate-ocr) trained on plates from the 65 countries below. Accuracy has not been verified for plates from countries that are not listed.

Turning vehicle recognition off

Items with a vehicle condition pause, and the list on the Actions tab shows Stopped: vehicle recognition is off. Turning it back on restores them.
Registered vehicles and saved records are not deleted.
At least one of person, face, vehicle, and animal recognition must stay on, so the switch cannot be turned off while vehicle recognition is the only one on.
