Compact video recorder and CVBS converter designed for FPV drones and RC model vehicles. Fast startup, flexible video format support, and builtin encoding and decoding make it a practical onboard DVR and field monitor tool. Key benefits Fast readiness: system starts in 3 seconds so you can begin recording quickly. Wide video compatibility: switchable NTSC and PAL input formats support most analog video sources. Builtin decoder and encoder: accepts CVBS signal input and provides CVBS output for playback and external display without extra converters. Recorded files are standard AVI with MJPEG compression for easy playback and editing. Flexible recording options: choose VGA 640x480, D1 720x480, or optional HD 1280x720 resolution, with cycle recording set to 10, 20, or 30 minutes. Portable power and clear status: micro USB charging at 5V DC 500mA maximum and a builtin 3.7V 400mAh LiPo battery delivering about 1.5 to 2 hours per working load with a level 4 battery power indication for accurate remaining runtime. Multilingual interface: 11 menu languages for international use and easy setup. Standout features Lowlatency 30 frames per second recording for smooth video capture. MJPEG compression in AVI format preserves usable frames while keeping files straightforward to handle. CVBS input impedance 75 ohm typical for standard analog camera connections. Audio input via 3.5mm AV jack with option to record sound or mute as needed. Video playback directly through CVBS output to an external display for immediate review in the field. Optical frequency selectable at 50Hz or 60Hz to match lighting conditions and reduce flicker.

FPV drone onboard DVR: connect an analog FPV camera to the CVBS input and capture flight video in AVI format. Use the HD option when higher resolution is needed or select D1 for a balance of quality and file size. Review footage on a field monitor via CVBS output after landing. 2. RC model racing car recording: mount the unit in the car to record races at 30 fps. Cycle recording keeps file sizes manageable and enables continuous capture during long sessions. Battery level indicator helps plan run times between charges. 3. Field testing and setup: use the builtin encoder and CVBS output to play back recorded clips on a display and verify camera alignment, wiring, and signal quality on site. Switch optical frequency to match local lighting and avoid flicker. Compatibility and installation notes Designed for FPV drones and RC model vehicles with analog CVBS camera systems. Use a speed Class 10 micro SD card for recording stability. Memory card sold separately. Connect power using a standard 5V DC micro USB source for charging. This device is a straightforward solution for capturing, converting, and reviewing analog video in hobby and field applications where fast startup, simple file formats, and onboard playback are required.
