5. Operation Guide

5.1 Dashboard

After logging into the web GUI, you can view live video and configure parameters. The dashboard displays data like Total In, Total Out, Children In/Out, and Staff In/Out.

5.2 Rule

Draw Detection Lines

Users can draw detection lines to record people entering or exiting. Click 'Draw Detection Lines', then left-click to start drawing, left-click again to change direction, and right-click to complete. Lines can be adjusted. Up to 4 broken lines with 4 segments each are supported. To delete a line, click 'Draw Detection Lines', select the line, and click 'Clear This Line' or 'Clear All'.

Note: The arrow direction indicates the counting direction. Ensure targets pass completely through the line. Perpendicular lines to the In/Out direction are recommended. Leave a redundant identification area on both sides of the line for stable recognition and tracking.

Rule Configuration

Users can set rules for accurate counting:

• Deployment Parameter: Installation Height, Max. Target Height, Min. Target Height, Child Filter Height.
• Counting Strategy: U-turns Filtering, Draw U-turns Areas, Children Distinction, Staff Detection, Input Enable Count Externally (PoE Version).

Note on Target Height: Due to ToF measurement error (0.035 m), Max Target Height should be pedestrian height + 0.035 m, and Min Target Height should be pedestrian height - 0.035 m. For example, for 1.6 m to 1.8 m height, set Max to 1.835 m and Min to 1.565 m.

5.3 Communication

6. Installation Instruction

Parameter Definition

6.1 Installation Height

The maximum installation height is 3.5 m. The minimum installation height is h_max + d + Δd. For example, with a maximum pedestrian height of 1.8 m, the minimum installation height is 1.8 + 0.5 + 0.035 = 2.335 m.

6.2 Covered Detection Area

The detection area depends on the field of view angle, installation height, and target height. The length (x) is approximately 2.300 × (H - h_min) and the width (y) is approximately 1.678 × (H - h_min).

Example table showing detection area for different installation heights (assuming minimum pedestrian height of 1.7 m).

6.3 Environment Requirements

Black floor/carpet may affect the depth map and cause noise but does not impact people counting. Avoid 940nm light which can cause incorrect counting. Mirrored reflections of sunlight on the ToF sensor should be avoided.

6.4 Installation

Ceiling Mount

1. Ensure ceiling thickness is > 30 mm. Attach mounting sticker and drill 4 holes (6mm diameter). Drill a wire hole if needed.
2. Fix wall plugs into ceiling holes.
3. Remove device cover, connect wires, and pass them through the wire hole or side opening. (Note: For VS133-P alarm I/O, connect a multi-interface cable).
4. Fix the device to wall plugs using mounting screws. Adjust mounting direction for detection area requirements.
5. Replace the device cover.

Ceiling/Lintel Mount (with Optional VB01 Multifunctional Bracket)

1. Attach the mounting plate to the device with 4 screws.
2. Fix the pole to the mounting plate.
3. Adjust pole length and 3-axis ball direction.
4. Drill 3 holes at the mounting location, insert wall plugs, and fix the bracket base with screws. (Note: Drill a wire hole if extending wires into ceiling/wall).
5. Remove device cover, connect wires, and pass them through the pole. (Note: For VS133-P alarm I/O, connect a multi-interface cable).
6. Fix the pole to the bracket base with screws and nuts.

Installation Notes: Avoid tilt installation; ensure the device front is parallel to the ground plane. Keep the device at least 30 cm from the short side wall and 50 cm from the long side wall. Ensure no objects block the ToF light within a 30 cm radius. For swinging doors, keep the door normally open. If normally closed, install on the other side of the door, at least 30 cm away from door movement.

6.5 Factors Affecting Accuracy

• Wearing hats or carrying boxes can prevent target recognition as they alter the human-like depth map.
• Handheld humanoid dolls can be mistaken for people due to their human-like appearance.

7. Communication Protocol

7.1 LoRaWAN® Version

Uplink Data

The VS133 reports sensor information and people counts periodically. Decoder examples are available at https://github.com/Milesight-IoT/SensorDecoders.

Note: If children distinction or staff detection is enabled, counts are adjusted (e.g., accumulated in counter = total in counter - children in). Example data formats are provided.

Downlink Command

VS133 supports downlink commands for device configuration. Application port is 85 by default.

Note: Changing LoRaWAN® parameters requires the device to re-join the network. Examples for disabling Wi-Fi, setting channel mask, rebooting, and setting reporting interval are provided.

7.2 PoE Version

The VS133-P posts people counting data in JSON format to HTTP URL or MQTT broker. Data includes Periodic Report and Trigger Report, with detailed JSON structures provided for event, device info, time info, period data, and trigger data.
