2. Parking Management Configuration

Enable Detection, select your country, and then draw the detection regions for Channel 1 and Channel 2 separately. Each space draw one region accordingly.

Note: Three vehicles can be detected on each channel （side）, for a total of 6 vehicles.

Note：Motorcycle Detection (new PM3322-E PI_61.8.0.5 above)

Scenes where motorcycles and motor vehicles are parked together. You can enable “motorcycle detection”; once detected, the vehicle_type will be reported as “Motorbike.”

3.Highlighted Features

3.1Indicator lighting settings

There are three parking space statuses: Free, Full, and Special. You can also choose different colors to represent each status. 

The "Special" status is user‑defined. Simply check the box for a parking space to mark it as "Special"，then the indicator color will accordingly match the space.

The light behavior for this product is as follows:

Example: Free --> Green; Full --> Red; Special --> Blue  

① All 6 parking spaces are occupied, display Red  

② Only 1–6 regular parking spaces are available, no special parking spaces available, display Green  

③ Only 1–6 special parking spaces are available, no regular parking spaces available, display Blue  

④ Both regular and special parking spaces are available, display Green

3.2 Linkage audio setting

You can enable audio and add audio file.

Then when a car pulls into/out , if you want, you can choose to play audio.

3.3 Detection Event (new PM3322-E PI_61.8.0.5 above)

1.Parking Across Spaces

An alarm is triggered when the proportion of the vehicle body covering the adjacent parking space exceeds this threshold.

2.Abnormal parking space occupancy

When a foreign object is detected occupying a parking space, an event is reported to facilitate precise cleanup by operations and maintenance personnel. Prerequisite: Foreign object detection is performed only when the parking space is determined to be “vacant”; if both a vehicle and a foreign object are present, the system prioritizes the vehicle as occupying the space (to conserve performance and prevent false positives).

5.Data transmission

5.1 Report Settings

For old PM3322-E（firmware below PI_61.8.0.5），only support report setting like below

The camera can be connected to the backend platform via TCP, HTTP, or MQTT. The indoor parking space camera first reports its account and password to the server. Whenever a parking space is occupied or released, it immediately pushes the update; periodic batch reporting is also supported. The report is in JSON format and includes time, parking space number, occupancy status, license plate, vehicle type, color, brand, and vehicle position.

Support trigger reporting and periodic reporting. You can find the detailed report content here.

5.2 Data transmission

For the new PGC models (firmware PI_61.8.0.5 or later)，a dedicated section titled “Data Transmission”

Regarding data transmission, we support three methods: HTTP, TCP, and MQTT. 

There are three types of reports: Trigger Report, Periodic (Interval) Report, and Timeout Report.

1.If you want to receive real‑time push notifications, once you check the "Enable" box, it will trigger a Trigger Report and push the data to the HTTP, TCP, or MQTT address you have configured.

2.If you want to receive notifications at scheduled intervals, you can enable the Periodic Report and set the desired time interval.

3.If you want to receive reports when the vehicle stop exceeds a certain duration, you can enable the Timeout Report here and set the desired time period.

Note：You can check the "Import File" option in the Data Settings to configure the format and data items for each report type.
