Product Overview

The AXIS APS401B is a versatile 4-sensor parking system engineered to provide comprehensive parking assistance for passenger vehicles through audible proximity alerts with unique customization options addressing individual preferences and vehicle aesthetics. The system uses four ultrasonic sensors mounted across the bumper providing full-width coverage that detects obstacles and triggers an audible buzzer with selectable volume levels (70-110dB) allowing users to adjust alert loudness for their hearing comfort and vehicle noise environment - quieter settings for sensitive hearing or quiet cabins, louder settings for noisy work vehicles or hearing-impaired drivers. The innovative dual mounting system offers both traditional in-bumper installation requiring 18.3mm holes and under-mount installation that attaches sensors beneath the bumper edge eliminating visible drilling for owners wanting factory appearance preservation. The flexible DIP switch configuration allows installation on either front or rear bumpers with front mode extended detection to 1.5m providing earlier warning during low-speed manoeuvring compared to standard systems.

Important Notes:

Professional Installation Recommended: Both mounting methods and electrical connections require automotive experience. Professional fitting ensures optimal sensor positioning and performance.

Mounting Method Selection: Choose in-bumper (drilled) or under-mount (no drilling) based on appearance preferences and bumper design compatibility.

Paintable Sensors: In-bumper sensors should be painted to match bumper colour. Under-mount sensors remain hidden beneath bumper edge.

4 Sensors for Front OR Rear: System includes four sensors for comprehensive single-bumper coverage (front OR rear only).

Extended Front Range: 0.3-1.5m front detection range longer than standard systems providing earlier warning during parking manoeuvres.

Frequently Asked Questions

Q: What's the difference between in-bumper mount and under-mount installation?

A: In-bumper mount is the traditional method requiring drilling four 18.3mm holes in your bumper face with sensors visible (but paintable to match). Under-mount installation attaches sensors beneath the bumper edge using brackets, eliminating visible holes and maintaining factory appearance - sensors remain hidden below the bumper lip. Choose in-bumper for maximum flexibility and standard appearance, or under-mount if you want no-drill installation preserving resale value or lease return requirements. Under-mount effectiveness depends on bumper design - some bumper shapes may not accommodate under-mount properly. Professional installer can advise which method suits your specific vehicle best.

Q: Why would I want to adjust the buzzer volume, and how loud is 110dB?

A: The selectable 70-110dB volume range accommodates different users and environments. Lower 70dB setting suits quiet vehicle cabins, sensitive hearing, or drivers who find standard parking sensors too loud or annoying. Higher 110dB setting benefits noisy work vehicles (diesels, commercial vans), hearing-impaired drivers, or vehicles with poor sound insulation where standard volume might not be audible. For reference, 70dB is similar to normal conversation volume, while 110dB approaches maximum comfortable listening levels. Most users start at mid-range and adjust based on preference. The adjustability makes this system suitable for diverse users from elderly drivers needing louder alerts to younger drivers preferring subtle warnings.

Q: What's the advantage of the extended 1.5m front detection range?

A: The extended 0.3-1.5m front detection (compared to standard 0.3-0.9m systems) provides significantly earlier warning when approaching obstacles during forward parking or low-speed manoeuvring. The extra 0.6m warning distance gives you more reaction time to stop, particularly useful when parking in tight spaces, approaching parking barriers that might damage low bumpers, or detecting low obstacles like parking bollards or concrete wheelstops. This extended range is especially valuable for vehicles with limited forward visibility, drivers new to their vehicle's dimensions, or situations requiring millimetre-perfect parking positioning. The system still detects close objects (0.3m minimum) while providing advance warning much earlier than standard systems.

Q: Can I install all 4 sensors on one bumper for maximum coverage?

A: Yes, the APS401B is designed with all 4 sensors intended for installation on either front OR rear bumper (not split between both), providing comprehensive full-width coverage eliminating blind spots on that bumper. Most users install all 4 sensors on the rear bumper since reversing typically requires more assistance due to limited rearward visibility. The 4-sensor configuration detects obstacles across the entire bumper width, significantly superior to 2-sensor systems that may miss objects between sensors. For complete front AND rear protection, you would need two APS401B systems (8 sensors total), though most drivers find single-bumper coverage adequate with primary installation on the rear.

Q: Does the under-mount installation work as well as drilling into the bumper?

A: Under-mount installation can work effectively when properly installed on compatible bumper designs, though in-bumper mounting is generally considered optimal for sensor performance. Under-mount sensors detect obstacles from beneath the bumper edge which slightly alters the detection pattern compared to forward-facing drilled sensors - you may experience marginally different detection angles or ranges. Success depends heavily on your specific bumper shape, ground clearance, and sensor positioning. Some bumpers with complex curves, excessive ground clearance, or inward-angled lower edges may not suit under-mount installation. Professional installers can assess your vehicle and recommend the most suitable mounting method. Many users successfully use under-mount achieving excellent results without visible bumper modifications.
