Rexing Dash Cam Placement and Power Guide

Power Options Explained

Rexing dash cams support three main power methods. Each has different trade-offs in installation effort, reliability, and parking mode support.

Mini-USB Power: DC 12V–24V (depends on your vehicle), 5V/1.5A typical, Mini-USB cable included with most models. Best for basic installs and temporary setups. Limitation: power cuts when the vehicle is off; no parking mode.

OBD Port Power: Direct from your vehicle's OBD-II port (12V–24V), 5V/2A typical, OBD-II cable (model-dependent). Best for clean installs on vehicles with accessible OBD ports. Limitation: not all vehicles have accessible OBD ports; some models need OBD-specific hardware.

GPS Hardwire Kit: 12V–30V (hardwire kit rated), 5V/2A via hardwire module, hardwire kit with fuse tap or direct battery connection. Best for parking mode, continuous recording, professional installs. Limitation: requires fuse tap installation; check your specific Rexing model's manual to confirm kit compatibility.

Electrical specs above come from current Rexing product information. Always confirm details on the Rexing product page or in your owner's manual before installing.

Step 1: Choose Mount Location

Recommended: center of the windshield, just behind the rearview mirror. Alternative: passenger-side A-pillar (less obtrusive). Avoid: airbag zones, defroster lines, areas that create camera blind spots. Mount types: suction cup (removable) vs. adhesive mount (permanent). Trade-off: adhesive holds better in heat; suction is easier to reposition.

Step 2: Connect Power

Mini-USB: plug the included cable into the dash cam, route it along the windshield edge, and connect to your vehicle's cigarette lighter or USB port. OBD: plug the OBD cable into the vehicle's OBD-II port (usually under the dashboard near the steering column). The dash cam should power on automatically. Hardwire: install the hardwire kit using a fuse tap (recommended) or direct battery connection. Follow the kit instructions for fuse selection. Check your vehicle manual to confirm the correct fuse rating.

Step 3: Position and Secure the Camera

Adjust the angle to capture the road ahead without excessive sky or hood. Tighten the mount securely. Test by gently pulling the camera — it should not shift. If using an adhesive mount, wait 24 hours before driving to let the bond cure.

Step 4: Install SD Card

Insert a microSD card (U3, Speed Class 10, microSDXC UHS-3 recommended) into the dash cam's card slot. Format the card in the dash cam settings before first use. Important: SD card capacity, endurance, and device-specific support vary by model. Check your specific model's product page before buying.

Step 5: Configure Settings

Set date and time (critical for evidence quality). Enable parking mode if using a hardwire kit. Choose resolution and frame rate based on your model's capabilities. Test recording by driving a short distance and reviewing the footage.

Accessory Compatibility

Rexing dash cams support several accessories. Compatibility varies by model. Use these rules to pick the right accessory. For model-level shopping context, start with the Rexing front/rear dash cam comparison, then confirm the accessory on the current Rexing merchant page.

Mount Accessories: suction cup mounts are universal fit for most Rexing models with a standard mounting base. Adhesive mounts are model-specific — recommended for permanent installation. 3M tape mounts are compatible with models that have a flat mounting surface.

GPS Loggers: GPS logger compatibility is model-dependent. Check your specific Rexing model's product page or manual for compatibility. GPS loggers add location metadata to video files for evidence enhancement.

Hardwire Kits: hardwire kit compatibility varies by model voltage requirements. Confirm the kit's voltage rating matches your dash cam's hardwire input specification.

SD Cards: recommended microSDXC UHS-3 (U3, Speed Class 10). Maximum capacity varies by model — check your product page for limits. Not all cards handle continuous recording — use cards rated for dash cam use.

GPS Logger and SD Card Guidance

GPS Logger: adds geolocation data to video files. Requires a compatible GPS logger module (model-dependent). Mount near the GPS logger module for best signal reception. Provides timestamp and location data for insurance claims.

SD Card Requirements: minimum U3, Speed Class 10. Recommended microSDXC UHS-3. Format in the dash cam before first use. Capacity varies by model — verify against your product page. Not all cards handle continuous recording — use cards rated for dash cam use. Capacity, endurance, and device-specific support claims vary by model. Always check your specific model's product page before purchasing.

Troubleshooting: Camera Won't Power On

Check the power cable connection at both ends. Verify the vehicle is on (engine running or accessory mode). Try a different power outlet (cigarette lighter, USB port). Test with a known-good power cable.

Troubleshooting: No Recording

Check the SD card is properly inserted and formatted. Verify recording is enabled in settings. Try a different SD card (known-compatible model). Check for firmware updates.

Troubleshooting: Poor Video Quality

Clean the lens with a microfiber cloth. Adjust the camera angle to reduce glare. Check the focus ring (if applicable). Verify resolution settings in the menu.

Troubleshooting: GPS Not Logging

Ensure the GPS logger is properly connected. Check GPS signal — requires clear sky view. Verify GPS logger compatibility with your model. Restart the dash cam after connecting the GPS logger.

Troubleshooting: Parking Mode Not Working

Confirm the hardwire kit is properly installed. Check the fuse rating — consult your vehicle manual for the correct rating. Verify parking mode sensitivity settings in the dash cam menu. Ensure the vehicle is locked (some models require a door lock signal).
