- To remove, gently push the card in until it springs out.

Operating Instructions
Basic Operation
Automatic Start Recording
The device is designed to automatically start recording when the vehicle's ignition is turned on and power is supplied. Recording will stop when the ignition is turned off.
Loop Recording
The dash cam records video in continuous loops. When the memory card is full, the oldest unlocked files will be overwritten by new recordings. You can set the loop recording duration in the settings menu.
Emergency Recording (G-Sensor)
The built-in G-sensor (accelerometer) detects sudden impacts or rapid acceleration/deceleration. When triggered, the current video segment is automatically locked and saved to prevent it from being overwritten by loop recording. This ensures critical incident footage is preserved.

Parking Mode

Night Vision
Equipped with a GC2053 sensor and 4-layer glass lenses, the Navitel R250 DUAL NV provides high-quality recording and clear images even in low-light conditions, enhancing visibility during nighttime driving.
