The Smart DVR mobile app is your personal video surveillance remote control, turning your smartphone into a fully featured monitoring and configuration center. It is designed for instant connection to a wide range of dashcams and hybrid devices through their built-in Wi-Fi modules, with no extra cables, adapters, or complicated network setup. The intuitive interface gives you full control over video recording in real time: start manual or emergency recording, activate motion detection, and quickly adjust microphone sensitivity and exposure settings. The built-in player lets you play saved files without delay, while fast export allows you to download the clips you need directly to your device's photo library in seconds. There is no need to remove the memory card or connect the dashcam to a computer. Camera settings are especially flexible: adjust video resolution, frame rate, bitrate, white balance, contrast, and saturation to suit any lighting conditions, from bright sunshine to deep twilight. Changes take effect immediately and are saved in the device's memory, making it easy to get the recording quality you need. Smart DVR also includes convenient file management: sort recordings by date, time, and event type, protect important footage from accidental overwriting, and use batch downloading to save data and time when transferring large amounts of footage. Supported devices: - KARADAR SRECORDER R102
