How to Install and Use the Haloview BT7 with TPMS Sensors and Axle Temperature Sensors: A Complete Guide for RVers
Whether you're heading out for rally season or logging thousands of miles towing across the country, keeping tabs on your tires and axles isn't just smart—it's essential. A tire blowout or overheated bearing at highway speed can turn a great trip into a nightmare in seconds.
That's why we installed the Haloview Byte Tango BT7 on our rig, complete with TPMS (Tire Pressure Monitoring System) sensors and the new Axle Temperature Sensors (ATS). Here's our full rundown on installation, setup, and real-world use.
What Is the HaloView BT7?
The Haloview BT7 is the world's first integrated wireless backup camera and RV tire pressure monitoring system. It combines two critical safety features into a single 7-inch touchscreen display:
- 1080P wireless backup camera with Wide Dynamic Range (WDR) technology for clear video in all lighting conditions
- Built-in TPMS that monitors up to 32 tires in real time, displaying pressure and temperature data on a single screen
The system operates on a 2.4 GHz wireless frequency with up to 984 feet of line-of-sight transmission range, making it suitable for rigs up to 65 feet. It powers through either a standard 12V cigarette lighter or a USB Type-C 5V port, giving you flexible mounting options in the cab.
What's in the Box
- 1x BT7 TPMS 7" touchscreen monitor
- 1x BTC128W rear camera (with WDR technology)
- 4x TPMS sensors (additional sensor packs available in 1, 2, or 4-packs)
- 2x signal boosters (repeaters)
For the Axle Temperature Sensors, you can purchase them in a 2-pack (single-axle) or 4-pack (tandem-axle). Each ATS includes a CR1632 battery and an anti-slip adhesive heat sink mat.
Installing the TPMS Sensors
Step 1: Prep Your Valve Stems
Haloview strongly recommends brass metal valve stems for their TPMS sensors. If your tires have rubber, plastic, or aluminum alloy valve stems, have your tire dealer swap them out before installation.
Step 2: Thread On the Sensors
Each TPMS sensor threads directly onto your tire's valve stem—no tools required beyond hand-tightening. Sensors include anti-theft lock nuts and are waterproof and rated for all weather conditions.
Step 3: Mount the Monitor
Secure the BT7 on your dashboard using the included suction cup mount or optional mirror mount. Connect to power via the cigarette lighter adapter or USB-C cable.
Step 4: Pair the Sensors
Two pairing methods are available: AUTO Learn (one-click, the monitor detects nearby sensors automatically) or Manual ID (enter each sensor's unique ID code through the on-screen keyboard).
Step 5: Install the Signal Boosters
For longer rigs, hard-wire the included signal boosters to a 12V or 24V source on your trailer. This ensures consistent readings even on a 40+ foot fifth wheel. The system comes with 2 repeaters; I also added one in the front bay.
Step 6: Set Your Alerts
Customize pressure and temperature thresholds for each tire position. The BT7 alerts you for: high/low pressure, high temperature, fast and slow leaks, lost sensor signal, and low sensor battery.
Installing the Axle Temperature Sensors (ATS)
The ATS clamps directly onto the axle near each wheel to monitor bearing and spindle temperature in real time — catching overheating from dragging brakes or failing bearings before it becomes a catastrophic failure.
Compatibility
- Designed for: Straight axles, MorRyde IS systems, and Curt TCS systems
- May work on: Some torsion axle systems, depending on available clearance
- Compatible monitors: HaloView BT7 TPMS, BT7 TPMS Solar, and BT10 TPMS
Step 1: Find Your Mounting Position
Clamp each ATS sensor onto the back of the axle as close to the wheel as possible. Look for a smooth, flat spot on the axle tube.
Step 2: Secure the Clamp
Tighten the included clamp hardware and apply the anti-slip adhesive heat sink mat between the sensor and axle for better thermal contact.
Step 3: Pair with Your BT7
ATS sensors must be paired manually (AUTO Learn is not available for axle sensors). Enter each sensor's ID code through the monitor's TPMS menu.
Step 4: Set Temperature Alerts
Under normal towing conditions, axle temps typically run 15–20°F above ambient temperature. If a bearing starts to fail or a brake is dragging, you'll see that number climb — and the BT7 will alert you with a red warning and audible alarm.
Installing the Rear View Camera
The Haloview backup camera is a direct replacement for the Furrion backup camera — the screw holes even line up in the same place. My camera paired to the head unit immediately. If needed, there is a pairing button on the bottom of the camera.
Real-World Performance
After running this full setup on our rig, here's what we've found:
- TPMS accuracy is rated at ±1.5 PSI and ±6°F — in our experience, spot-on
- Pressure range of 0–218 PSI covers everything from light-duty to heavy commercial trucks
- Real-time overlay on the camera view cycles through each tire's pressure and temperature every 5 seconds
- Axle temps during multi-hour tows stayed consistent and closely tracked tire sensor readings
- Wireless signal remained solid throughout thanks to the boosters — no dropouts
- Battery life on sensors is approximately one year; CR1632 batteries are user-replaceable
Why This Matters for RV Safety
Tire failures and bearing breakdowns are among the most common — and most preventable — causes of RV roadside breakdowns. The HaloView system gives you continuous, real-time data right on your dash while you're driving — when it matters most.
Tips and Best Practices
- Check sensor batteries annually. Mark your calendar — CR1632 batteries are inexpensive and easy to replace.
- Use brass valve stems. Don't skip this step. Wrong material can damage the sensor and rim.
- Install signal boosters on your trailer — even on shorter rigs, they improve reliability.
- Set conservative alert thresholds. An early warning beats a late one every time.
- Inspect ATS clamp tightness periodically. Road vibration can loosen hardware — check during pre-trip inspections.
- Keep a spare sensor and batteries in your tool kit for mid-trip replacements.
Final Thoughts
The Haloview BT7 with TPMS and Axle Temperature Sensors is one of the best investments we've made for towing safety. Having real-time tire pressure, tire temperature, and axle temperature data all on one screen — alongside a 1080P backup camera — means we can focus on enjoying the road instead of worrying about what's happening behind us.
Regular inspections and routine maintenance keep you off the side of the road. Adding a monitoring system like this takes it a step further — it keeps you informed between those inspections, every mile of the way.
