A car black box is a device that monitors and records important driving data and stores it in case of an accident. Typically, it monitors and records the image in front of and inside the car, the time and date. The dvr4d-2 black box is used to record video and audio in a continuous loop. It can record data from up to 4 cameras and microphone at the same time. The signal from the microphones must be amplified by a preamplifier. If the vehicle is involved in an accident, collision, or other events, the event is marked and stored on one of the two SD cards. It is then possible to analyse the data, find the causes, replay the scene and determine the acceleration, vehicle speed, direction and location of the event thanks to the built-in GPS. Video and audio are continuously recorded from the moment it is switched on. If the memory is full, the oldest recordings are overwritten by the most recent. The card is locked under the vault door and cannot be tampered with without keys. If an unusual acceleration or deceleration occurs and the built-in G-Sensor detects that the set limit has been exceeded, the operator manually activates the record button or the alarm wire is triggered, the recorded video is stored in a separate folder. The saved data will not be deleted if recorded to SD card, the user can delete the data after reviewing the SD card. The recorded data can be played back using the playback software.The SW is stored in the manuals section. (After installing the SW, you need to change the Record type to Unencryption in the settings). The cameras are not included in the package. For AHD resolution it is necessary to use a special camera with AHD transmission, e.g.: SVC502ccdAHD (AHD10 cameras cannot be used).
