How to Mount Gen 4 Pro Wildfire Sensors for Satellite Connectivity (Permanent and Temporary Methods)

Proper mounting of Silvanet Gen 4 Pro Wildfire Sensors is critical to ensure accurate environmental monitoring and reliable fire detection. This guide provides step-by-step instructions for both permanent and temporary mounting methods, helping your team deploy sensors safely and effectively. Following these methods will maximize sensor performance while minimizing impact on trees and the surrounding environment.

Before Mounting the Sensor

General Requirements for Satellite Installations

The following requirements apply to all sensors using Satellite connectivity, regardless of mode:

• Select a mounting position with a south-facing orientation at the planned sensor location before starting installation.
• Ensure the sensor has a clear line of sight with an angle of approximately 20–30 degrees to the horizon.
• The sensor must not be installed indoors or in locations surrounded by large buildings, as this may obstruct signal transmission.

Additional Requirements for Weather Station Mode

When deploying a sensor in Weather Station Mode, the following additional considerations apply:

• Where possible, select a semi-shaded location to support the most accurate environmental measurements.
• In areas with strong and continuous sun exposure, a north-facing orientation is recommended to help minimise potential impact on environmental readings.

Note: See our article Best Practices for Deploying Gen 4 Pro Sensors in Weather Station Mode for Further details of deploying in Weathr Station Mode.  

Permanent Method: Mounting with Treenails

Installation using the provided wooden nail and an 8 cm spacer.

1. At the planned sensor location, select a healthy tree with suitable installation space approximately 3 m above the ground and with a south-facing orientation.

2. Clear any excessive bark from the installation area to create a flat mounting surface, taking care not to damage the tree.

3. Drill a 6–7 cm deep hole using a 10 mm drill bit.

   • For hardwoods, begin with a smaller drill bit before switching to the 10 mm bit.

4. Using the Silvanet Deployment App, scan and register the sensor within your site. 

5. Insert the treenail through the sensor loop and the 8 cm spacer.

6. Carefully hammer the treenail into the drilled hole.

7. Ensure the sensor hangs freely, vertically, and without tension.

Why the Spacer Matters:

• Ensures optimal satellite connectivity 

• Helps keep the sensor protected from tree sap 

• Reduces direct contact with the tree surface for improved long-term stability

Temporary Method: Garden Wire

1. At the planned sensor location, select a healthy tree branch with suitable installation space approximately 3 m above the ground and a south-facing orientation.

2. Cut the garden wire to approximately twice the circumference of the tree branch.

3. Feed the wire through the loop at the top of the sensor.

4. Using the Silvanet Deployment App, scan and register the sensor within your site.

5. Loop the garden wire snugly around the branch, forming an “X” shape for maximum stability, then twist the wire securely to fasten it in place.

6. Ensure the sensor hangs securely and remains stable after installation.

Why the sensor stability Matters:

• If the sensor is too loose, it may lead to inaccurate detection and environmental readings.

Note: Garden wire can damage tree growth and should only be used for temporary installations or testing purposes.
