As a dog owner, I recently installed the T800Pro 4-in-1 Invisible Dog Fence, which integrates an invisible fence, remote training, bark control, and dog status monitoring. However, during the setup and usage, I encountered some signal issues that led me to explore ways to optimize the signal coverage to ensure my dog's safety and freedom within the designated area.

Radius Distance and Signal Stability
The radar-based invisible dog fence transmits signals horizontally, which can be easily disrupted by obstacles. The main objects that affect the signal include metal objects, large solid materials, and electronic devices. To ensure signal stability, I took the following measures:
-
Avoid Obstacles: Ensure that there are no metal objects, large solid materials, or electronic devices within 3 meters of the transmitter.
-
Adjust Transmitter Position: If there are large metal objects between the transmitter and the receiver, they can directly block the signal. Therefore, I placed the transmitter in an open area, avoiding any objects that might obstruct the signal.
-
Optimize Fence Layout: When there are two walls or large solid materials over 20 cm thick, the signal weakens. In such cases, I set the fence radius between 64 to 80 feet.
-
Test Signal Strength: In open areas, the maximum radius can reach 120 feet (F900 series) or 280 feet (F910 series). Before setting up the fence, I conducted multiple tests to ensure the signal was stable at the boundary.
Signal Loss and Fence Effectiveness
During testing, I found that signal loss or intermittent signals within the boundary do not affect the fence's effectiveness. As long as the signal is stable at the boundary, the fence will work properly. Therefore, before putting the fence into use, I conducted a detailed test to ensure the signal was stable at the boundary.
Testing Methods and Precautions
When testing the signal, I noted the following:
-
Dwell Time: Stay at the test point for a longer period to verify the long-term stability of the signal.
-
Avoid Sleep Mode: If you place the receiver at the center and move the transmitter to test the boundary signal, ensure the receiver is not in sleep mode.
Reasons for Fence Ineffectiveness
If the fence becomes ineffective during use, it could be due to the following reasons:
-
Signal Testing Issues: Ensure that the signal is tested at the boundary before putting the fence into use.
-
Mode Switching: Check if the system has been switched from test mode to operational mode.
-
Equipment Issues: If the system is still not giving proper warnings in operational mode, it might be an equipment issue.
Tips for Optimizing Signal Coverage
To optimize signal coverage, I took the following steps:
-
Raise Transmitter Position: In a forested area, hanging the transmitter on a tree works better than placing it on the ground. In sloped areas, placing the transmitter at a higher elevation provides better results than placing it at a lower elevation.
-
Adjust Transmitter Angle: If you cannot avoid solid walls, placing the transmitter at an angle works better than placing it at a right angle.
-
Choose the Right Location: In a rectangular space, placing the transmitter in the center works better than placing it on any side.
