Installation

Step 1: Install the Dash Camera

Adhesive Mount: Place the 3M tape on the mount and properly orient the mount square to the roof and hood line of the vehicle. Firmly press the mount onto the windshield. Wait at least 20 minutes before mounting the camera. Orient the mount as shown.

Suction Cup Mount: Remove the protective plastic from the suction cup, clean the mounting area of the windshield with rubbing alcohol, and wipe dry with a lint-free cloth. Clean the back of the suction cup with rubbing alcohol and wipe dry with a lint-free cloth. Apply moisture to the suction cup to create a better seal and mount the suction cup to the windshield. Wait approximately 30 minutes for it to dry. Once dry, attach the device by fitting the tab on the top of the mount into the slot on the top of the device.

Step 2: Insert the memory card

The Rexing R4 Plus accepts Class 10/UHS-3 or higher Micro SD memory cards up to 256GB. You will need to insert a memory card before recording. Before inserting or removing a memory card, ensure the device is powered down. Gently push the memory card in until you hear a click; the spring release will push the card out.

Step 3: Power on the Camera and Format the Memory Card

Power the camera by connecting the charger to the car cigarette lighter and camera. Before using a new memory card, you MUST format it within the camera using the format function. Always back up important data stored on the memory card before formatting.

To format the memory card: ensure your memory card is inserted, turn on the device by connecting to a power source. Press OK to stop recording. Then press the MENU button twice to enter the Menu.

The dash cam automatically searches for the GPS signal once connected to the power source. Press the MENU button once and go to Video Settings. Toggle the GPS setting and select your preferred speed unit.

Parking Monitor (Parking Surveillance Mode)

Parking monitor provides surveillance on your parked vehicle. When the engine is off, the hardwire kit provides continuous power and protects your car battery from being discharged.

Option 1: Vibration Detection

To enable the Parking Monitor, connect it with a Rexing Type-C Smart Hardwire Kit (sold separately).

Illustration description: Wiring diagram for the Rexing Type-C Smart Hardwire Kit, showing connections to Battery, ACC, and Ground.

This feature allows the dash cam to switch to parking mode automatically if the vehicle's engine turns off and switch back to normal recording after the vehicle's engine turns on.

Gravity Sensing Record:

Gravity Sensing detects significant or sudden movement (such as an impact or collision), triggering an event recording. Rexing suggests setting "Gravity Sensing" to High sensitivity for Parking Mode Recording.

Note: If you do not use the parking mode function, change the Gravity Sensing sensitivity to low. Otherwise, videos may be locked and cannot be deleted by the loop recording function, leading to a full memory card of locked videos and potential recorder malfunction.

DO NOT ENABLE the Parking Monitor function without connecting a smart hardwire kit, as this may cause a malfunction.

Option 2: Motion Detection

To use this feature, connect it with a Rexing Type-C Intelligent Hardwire Kit (sold separately). Ensure that the Parking Mode is turned off on your dash cam, otherwise it may cause a malfunction.

Once the sensor detects MOTIONS, the intelligent hardwire kit will power up the dash cam automatically and start recording until the MOTION is cleared.
