Buyer’s Guide: What to Consider

Choosing the right parking sensor kit for your work van involves a few key factors. Here is what to consider before you buy.

• Sensor Count and Coverage: Four sensors cover the rear; eight add front protection. For vans, front sensors help avoid low curbs and walls in tight spaces.
• Detection Range: Look for at least 1.5 to 2 meters. Longer range gives earlier warnings, crucial for long vans with slow reversing speeds.
• Weatherproofing: Sensors must handle rain, mud, and road salt. Check for IP ratings or explicit waterproof claims to ensure durability.
• Installation Type: Wireless kits save time and avoid cable routing. Wired kits are often more reliable but require more effort. Consider your comfort with DIY.
• Extra Features: Tow-bar recognition, self-test functions, and adjustable volume add safety and convenience. These are valuable for vans with rear protrusions.

Conclusion

Parking sensors are a smart investment for any work van. They prevent costly bumper damage and improve safety in tight spots. The best choice depends on your van’s needs: simple rear alerts, full front and rear coverage, or wireless convenience.

For most van drivers, the ELSNU 8-sensor system offers the best all-around protection. If you have a tow bar, the Promata PS02 is the standout. For a quick, wireless install, the EKYLIN cordless kit is hard to beat.
