WL15 vs WL40 – Key Differences

---

️ How It Works

Both models use a non-contact millimeter-wave radar sensor mounted in the PTZ dome to continuously monitor the distance to the water surface. The difference is how far the radar can reach:

• WL15 is suitable where the camera is installed relatively close (e.g., mounted 3–8 m above the water).

• WL40 is suitable where you need to measure deeper bodies of water or place the camera higher, up to 40 m above the surface.

Both retain:

• ±1 mm measurement accuracy

• Configurable thresholds

• Real-time alert triggering

• Environmental protection (IP67/IK10)

• 4G or wired network support

✅ Which Should You Choose?

✅ Installation for Flood Detection

1. Choose the Right Location

• Mount the camera above the water body (e.g. culvert, river, stormwater drain, retention basin, etc.)

• Position it directly over or adjacent to the target detection area (vertical or angled is acceptable as per radar specs).

• Ensure clear line-of-sight to the water surface — no tree branches, debris, or reflective surfaces that may interfere with the radar.

2. Mounting Requirements

• Mount the unit securely on a fixed pole, bridge, overpass, wall bracket, or gantry. The radar needs to remain stable and vibration-free for accurate readings.

• Recommended mounting height is based on anticipated flood levels + safe offset, typically:

  • 3–5 metres above normal water level

  • Still within the 15 m radar range (this model detects between 0.5–15 m)

• Use brackets rated for the dome’s weight and environmental exposure (IP67 / IK10 housing will withstand tough weather).

3. Power and Network

• Connect 12V DC or 24V AC or PoE (if applicable) – check power draw for low‑power deployments.

• Insert SIM card for 4G LTE operation if remote area (ensure signal strength at the site).

• Alternatively, use LAN if available.

• Setup remote connection to your VMS, NVR, or HikCentral if applicable.

⚙️ Configuration for Water Level Alerts

Step-by-Step Configuration:

1. Access the Web Interface

• Log into the camera via browser (default IP) using admin credentials.

• Navigate to Configuration > Radar > Water Level Detection.

2. Enable Radar Functionality

• Turn on the millimeter-wave radar and perform calibration:

  • Define the reference point (zero level) – typically the normal water level.

  • Use the built-in calibration wizard to auto‑detect the base level.

3. Set Alert Thresholds

• Configure the threshold level where you want to receive alerts.

  • E.g., if normal level is 2 m, set flood warning at 3.5 m and critical alert at 4.5 m.

• You can set multiple zones (e.g., low, medium, high) and trigger different actions per zone.

4. Configure Alarm Actions

• Go to Event > Smart Event > Water Level Detection.

• Set up alarm linkages such as:

  • Email notification

  • Push notifications via Hik-Connect or Hik-ProConnect

  • Trigger output relay to activate a siren/strobe

  • Upload snapshot/video to FTP

  • Pop-up window on VMS or mobile app

• You may also configure custom audio warnings if connected to a speaker.

5. Test the System

• Simulate increasing water by aiming radar at fixed targets at known heights.

• Confirm correct triggering of alarms when the threshold is exceeded.

• Review logs, images, and event recordings to verify operation.
