Power Supply

Powered by Type-C Power Adapter (5V, 3A)

Note: If the default power cable length does not suit your application, please add a Type-C extension cable and ensure the length of extension cable matches the formula below:

$R * 3 A \leq 5 V - 4.2 V$

Where:

R—Cable Resistance in Ω, refer to Wire Resistance Calculator.

Installation Location

Installation Height: 2.3~3m.

Installation Location: Ensure the center of radar placed in the center of detection area. Take a room without any objects as example, place the device on the ceiling with the center of radar matching the center of the room. The long side of the device should align with the longer dimension of the room, while the short side should align with the shorter dimension of the room.

Note:

If the centered position of the room ceiling is not suitable for mounting the device, find a proper position that is at least 1 meter away from the wall.
Ensure the installation location of the device is flat and stable to avoid tilting or instability.
Avoid installing the device near ceiling fans or chandeliers.
Minimize the accumulation of cabinets or clutter within the device's detection range, and avoid the presence of large metal surfaces, mirrors, or other reflective objects nearby.
The room size, installation height, and detection height should be accurately measured using tools such as a rangefinder or tape measure before setting.

Installation Steps

Ceiling Mount

Step 1: Drill two 6 mm holes aligned with the screw positions of the device, then insert wall plugs into the ceiling.

Note: If you need to hide the power cord inside the ceiling, drill an additional hole for the wire.

Step 2: Cut a side wire hole according to the mark on the device, and thread the power cable through the side wire hole.

Note: If the DO wiring is going to be used, please connect the DO wiring to the device, then pass it through the side wire hole.

Step 3: Fix the device to the wall plugs using the mounting screws.

Step 4: Align one edge of the T-shaped Spirit Level with either edge of the device and adjust the device until both water bubbles are centered, ensuring that the device is perfectly parallel.

Step 5: Install the silicone plugs.

Cutout Mount

Step 1: Drill a hole with a diameter of 76.3~80mm in the ceiling.

Step 2: Fix the spring clips to the device with screws.

Step 3: Cut a side wire hole according to the mark of the device, and thread the power cable through the side wire hole.

Note: If the DO wiring is going to be used, please connect the DO wiring to the device, then pass it through the side wire hole.

Step 4: Insert both spring clips vertically into the ceiling hole by hand.

Step 5: Align one edge of the T-shaped Spirit Level with either edge of the device and adjust the device until both water bubbles are centered, ensuring that the device is perfectly parallel.

Step 6: After the device is completed, install the silicone plugs.

Access the Web GUI

VS373 provides user-friendly web GUI for configuration access via Wi-Fi. Users need to customize the password when using the device for the first time. The default settings are as below:

Wi-Fi SSID: Fall Detection_XXXXXX (can be found on the device label)

Wi-Fi IP: 192.168.1.1

Enable the Wireless Network Connection on your computer, search for corresponding Wi-Fi SSID to connect it, then type 192.168.1.1 to access the web GUI.
