Some explanations. What some features bring?
The concept of border cameras refer to the ones that are allowed to introduce and exit cars (add and subtract and calculate cars inside report) from a parking lot when a number plate is detected. The other cameras will only act as sensors and will do an action if set but they will not decrease or increase number of vehicles in the parking lot. The new version comes to solve some challenges for the customer: in fact, the border camera setting is meant for a parking lot that has more areas where one is transited in the way to another, so only one camera will have the functionality of adding or subtracting numbers of vehicles from the parking lot.
Crop
Crop is a special setup in Area Counter where only the defined areas are cut out of the image and analyzed independently. In comparison, the “full” setup means the defined areas are also analyzed but all at once, not individually. Crop will analyze each detection area as it would be an independent frame, for a better accuracy.
Microscope
Also, the Microscope feature means a single image frame is cut into very small areas (tens for each frame, but depends on the resolution of the image) which are analyzed individually. This will lead to better detection for very small objects in the image but a very slow speed, usually up to 10 seconds for each frame. You can see as such people which are very small in a high resolution camera watching a big square, for example. In fact the engine does the same as in the Crop feature. Each “image cut” is analyzed independently as it would be a normal frame. Then the entire image is recomposed, the duplicates are eliminated (if an object happens to be at the intersection of a cut) and a final result is delivered with the output of the detection.
The better the resolution, the better the results, but also the speed will decrease, as the image is split in tens of other small parts which are analyzed one by one and this is where the slow result comes from.
Anti-passback
Anti-passback is a feature that can be used to prevent users from passing their access credentials back for another user to borrow and to stop users entering an area. When a vehicle/access card is detected and this feature is activated, Metrici is searching in its database to see if it is already registered as in the parking or out of the parking. If that's the situation as this particular number plate /access card is registered at that moment as being “inside”, the action set for that particular number plate will not be taken. This feature will prevent the habit of borrowing access cards for multiple accesses in a parking lot. It aims to prevent consecutive entries for one access card, or prevent multiple people from using the same access card. It is a security protocol that prevents cardholder credentials from being used for improper access.
Other features in the launch
Tenants and Groups import and export are meant to easy the work of our clients, who have a better possibility to manage parking with tens or thousands of users. For any import, you have the option to eliminate and replace the old list or to add only the new entries. On the other hand, the show groups number plates button is useful in situation of import and exports actions when only new cars can be imported which do not belong to neither groups or tenants. So you can manage the groups individually.
The import and export for groups and tenants allows also to change one to another if one wants to. For example, you export a created group and you can import it as tenant. Or the other way around.
Comparing to the group, the tenant has the possibility of managing its own plate and add as many number plates as it wants, but can only enter a parking with the maximum number of vehicles allocated to it.
You can have 20 cars in the list, but only two parking spots, so this is the maximum number of cars permitted to be inside simultaneously, at any given time. One goes out, then another can enter and so on.
Also, the tenants action list and number plates will have a distinct entry in the Interface and will not be visible in LPR menu. This allows managing plates which are not included neither in group or tenants with import and export options, among other settings.
