Search by LPs

With search by LPs, you can find the recognized license plates in the archive, as well as filter them according to specified criteria.

To search by license plates, do the following:

1. Set a search interval (see Setting a search interval).
2. Select the detector from the list by the events from which you want to search.

3. Enter the license plate that you want to find. You can enter either a full license plate or a part of it using the ? character (any character in the license plate) and the * character (any number of any characters in the license plate). For example, a search query ?20* shows all vehicles with license plates containing 2 and 0 in the second and third positions, respectively. License plates can contain any number of characters.

   Note

   To search by all recognized license plates, enter * (asterisk).
