Prepare for the first drive.
Secure the mount
Clean and dry the windshield, apply the electrostatic sticker and fit the 3M mount as illustrated. Position the camera behind the mirror without blocking your view.
Insert the memory card
Power off before inserting or removing the card. Use Class 10 / UHS-I or higher microSD up to 128GB. The REV05222025 guide lists a 32GB card in its package.
Power and format
Connect the supplied charger and USB-C power cable. If the camera displays a format prompt, press LOCK to confirm. Back up files first: formatting erases the card and may take a few minutes.
Connect nearby. Keep the footage.
Join the camera Wi-Fi
Wi-Fi enters standby automatically when the SC4KS is powered on. On your phone, join SC4KS_XXXXXX using the displayed details; the guide lists the default password 12345678.
Open Rexing Connect
Open the app and select Connect. Stay on the camera Wi-Fi if your phone reports no internet. The camera’s Wi-Fi indicator turns green when the app is connected.
Review and download
Open Video Playback from the app home screen. Hold a clip to select it, then use Download to save it. Review the unlocked, locked and parking-video lists.
Use app controls
The app home screen provides Start/Stop recording, capture, settings and photo/video access. Complete setup while parked.
Check time and date
The SC4KS syncs its date and time with the phone when connected through the app. Check the displayed time before relying on a recording’s timestamp.

Match the kit to the mode.
Vibration detection
The guide specifies the included OBD Smart Hardwire Kit for this mode. Correctly connected, it switches the camera to parking when the engine stops and back to normal recording when it starts.
Motion detection
Use the Rexing 360° Intelligent Hardwire Kit, sold separately. Keep Parking Mode off on the camera; the kit powers it when motion is detected.
Power protection
Follow the exact kit’s installation and battery-protection instructions. Parking recording cannot continue after the kit stops supplying power.
A clearer next step.
Wi-Fi connects but the app does not
Stay connected to the SC4KS network and return to Rexing Connect. Confirm you selected Connect. Some phones need another attempt; do not switch to a different Wi-Fi network during setup.
Why is the recording indicator yellow?
The guide identifies flashing yellow as a locked current clip, flashing red as recording, gray Wi-Fi as standby and green Wi-Fi as app-connected.
Which format instructions apply?
SC4KS uses a LOCK-button confirmation when a format prompt appears. Use the SC4KS guide here rather than another model’s MENU-button instructions.
