Why Does My Kangaroo Motion Sensor Keep Triggering False Alarms From My Pets
- Sensor mounted too low for pet immunity
- Pet size exceeds sensor pet immunity rating
- Sensor aimed at pet traffic areas
Problem Description
Your Kangaroo motion sensor triggers alarms when your pets move around the house. You get constant false alerts from your dog or cat, making the motion sensor unusable while you are away. Disabling the sensor defeats the purpose of having security coverage.
Symptoms
- Motion alerts every time pet walks by sensor
- Cannot arm system due to pet triggers
- Constant false alarms when away
- Large dog triggers but small cat does not
- Pet triggers sensor even when sleeping nearby
- Motion sensitivity already at lowest setting
Recognize these? Here's what usually causes it.
Common Causes
- Sensor mounted too low for pet immunity
- Pet size exceeds sensor pet immunity rating
- Sensor aimed at pet traffic areas
- Sensitivity too high for pet environment
- Multiple pets creating larger heat signature
- Warm-blooded pet in cold room increases detection
Most fixes happen in the first 3 steps.
Masking or blocking the sensor lens voids any warranty and may create security blind spots. Use this method only as a last resort and test thoroughly.

Step-by-Step Solution
Raise Sensor Mounting Height
Most PIR motion sensors can ignore pets when mounted at the correct height and angle. Mount the Kangaroo sensor 6-7 feet high, angled down at 30 degrees. This creates a detection pattern that starts a few feet off the ground, above where most pets walk but still catching standing humans.
Redirect Detection Away from Pet Paths
Identify where your pets commonly walk and aim the sensor away from those paths. If your dog walks along the wall, mount the sensor on that wall so it looks across the room instead of down the pet pathway. The sensor detects movement across its field better than toward it.
Adjust Sensitivity Settings
In the Kangaroo app, check if motion sensitivity is adjustable. Lower sensitivity requires larger heat signatures to trigger, helping ignore smaller pets. However, this may also reduce detection of humans at the edges of coverage. Test at different levels.
Create Pet-Free Detection Zones
If your home layout allows, set up motion sensors only in areas where pets do not roam, such as an upstairs hallway or home office with a closed door. Use door/window sensors for pet-accessible areas instead, which detect entry but not pet movement inside.
Consider Sensor Masking
Some users apply masking tape to the lower portion of the sensor lens to block the bottom detection zone. This creates a DIY pet immunity area. Test carefully to ensure you still detect crouching or crawling intruders. This is a workaround, not a perfect solution.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
Pet immunity works best with pets under 40 lbs. Large dogs are difficult to distinguish from humans in heat signature. Consider alternative coverage strategies for homes with large pets.
False alarms cluster in two windows: the first two weeks of installation, and years later as sensors age. Rarely anything in between.
