Halo Collars only issue fence preventions if its GPS location is next to or over the fence boundary, the dog (and collar) are moving away from safety, the collar is in high GPS mode, and the collar is not on the charger. When a dog wearing the collar comes inside, the collar should transition to show a low GPS status (via the pet card) as it will begin to receive weaker GPS satellite signals. When showing a low GPS status, the collar will pause its position on the map at its last reported location, which is sometimes away from the house and occasionally closer to or over the fence boundary. If the collar were to pick up stronger satellite signals while in the house, which often can occur around windows, upstairs, near exterior walls/doors, and in garages, then it will transition into medium or high GPS mode. While in these two modes, automatic fence feedback can occur if the collar's position on the map is still near or over the fence. Some drifting of the collar's backend GPS position can naturally occur when indoors and stationary for long periods, but indoor feedback should not be an issue if the collar is staying in low GPS mode.

While working to fix this issue, you should turn fences off when your dog is in the house to prevent erroneous corrections. Make sure that you turn fences back on before letting your dog out again.

1. Ensure your collar's firmware and the app are up-to-date
   
   • Check your collar’s firmware version using this article
   • If your Halo Collar downloads and applies a firmware update, you may be prompted to take the collar outside to allow it to re-calibrate to GPS signals. For more information on this re-calibration process, check out the article "How to optimize GPS accuracy"
   • Check that your Collar has up-to-date satellite position data by checking on Settings->Collars->Advanced Settings->Satellite Position Data
2. Ensure the perimeter of your Halo Fence is at least 15 feet (4.6 meters) away from your house
   • Edit your fence using this article
   • This can help create a greater buffer area around your house to help prevent indoor feedback so the bigger the better.
   • Adjusting the fence perimeter should also be done to allow your dog ample room to roam within the fence's safe area without getting too close to the boundary once optimum accuracy has been reached. 
3. Utilize beacons set to Ignore Fences mode
   
   • While a beacon is set to this mode, a collar that is within range of the beacon will not have any fence prevention feedback issued to it.
   • This is a very effective option if your indoor issue consistently occurs in the same location inside your home or even outside inside your fence.
4. Check the collar's current position on the map.
   • If it is showing that it is near the fence then you can take the collar in hand and bring it outside in high GPS mode so that it can update its position. Just make sure to slightly shake the collar so the sensors can be triggered which will allow a location update to be issued.
   • It helps to open the Halo app and to view the pet card when your dog is heading indoors or before you place the collar on them when going outside.
     • Viewing the pet card will allow for real-time location updates to the server and app which will place the collar in a closer position to you or your house once it transitions into low GPS mode.
     • Checking the pet card before placing the collar on your dog when going outside will allow the collar to have a more accurate starting position as the collar naturally would need to recalibrate itself some after being indoors and stationary for long periods. 
       • The collar must have a strong or medium GPS status in order for its position on the map to update. What do the lights on the collar mean?

   • You can hand-test the collar by using the instructions in this article

5. If outside with the collar and it is issuing feedback even though the collar is not physically near the fence boundary, then check the app to see where the collar thinks it is. 
   • Make sure that if the collar has not been used in some time or recently had a firmware update you allow it to calibrate out in the open.
   • Further time outside and movement by the collar will be required in order for the collar's accuracy to increase.
   • Taking your dog on a walk with the collar or bringing the collar in the car with you should greatly increase collar accuracy quickly due to the continuous and substantial movement. 
6. Adjust GPS Signal level settings (indoor/outdoor configuration) so the collar's Low/Strong GPS signal detection will be better optimized for your environment.
   • Set this so the right slider (upper threshold) is in an area that allows the collar's GPS signal to consistently be greater than the value on the slider when the collar is being worn. The left slider (lower threshold) should be set to a value that will mostly show the GPS signals that are making it to the collar are less than the threshold you set for it, when the collar is being worn.
     • The low, medium, and high GPS modes are only relevant when the collar is being worn
     • Allow a buffer area in between the two thresholds for medium GPS, which will allow the collar's position on the map to move when motion is detected but will only issue a return whistle if it thinks it is over the fence boundary. 
       • Decided whether you would rather see the medium GPS mode lean more towards indoors or outdoors. Personally, I would rather see the collar occasionally go into medium GPS mode when it is worn indoors or semi-outdoor environment than when outside as I would rather see full fence preventions when outside in the open in an area with a clear view of the sky.
   • This process can be performed more than once. If it appears performance is getting worse, reach out to customer support for further assistance. A screenshot or screen recording of the issue can be helpful. 
     • If you need assistance with adjusting your levels then we ask you to share a date and time frame for when the collar was being worn by your dog and was indoors moving around and then went outdoors and moved around for about 5 minutes in both locations. Follow along from the GPS level setting page so you can view the changing signal strengths and more data can be transferred to the server. Please mention if the collar is going near large windows, garages, patios, or upstairs when doing this as these areas will naturally allow for stronger signals to reach the collar. 

We're here to help, so don't hesitate to reach out to our virtual Dog Park if you have any questions. We suggest including a screenshot or screen recording, with the audio, of what you are seeing on the map along with the description of your issue as this will help us research it further.
