  • The CDR-520 is our commercial Black Box type DVR system that supports up to four cameras for simultaneous recording around the vehicle. The CDR-520 will activate when the ignition system is powered up and activates all four cameras to start recording. The DVR system will continue to record as long as the ignition is on. It also has a series of trigger inputs that will allow the system to activate and start recording on designated camera inputs.

  • The CDR-520 uses up to four 32GB SD cards (128GB max) for recording storage making it the largest DVR system in our inventory in terms of memory capacity. When the ignition cycles on, the DVR system will power up all four cameras, or how ever many are plugged into the system and will begin recording. When one SD card is full, the system will begin storing recordings onto the next one until all SD cards are full. The system has a cyclic recording feature so when all SD cards are full, the system will automatically begin re-writing over the oldest recorded file. The CDR-520 also supports a USB connection to allow recordings to be backed up onto a flash drive instead of leaving all the recordings stored on the SD card. The user can go into the system and select which recordings that want to be saved and back them up onto the USB device.

  • The CDR-520 gives you full control when it comes to custmizing your recording options. Not only does it simply record on all four cameras when the ignition is on, but you can also set the system for timer recording as well. The user the program each individual video input to start recording any time of day on any day of the week. This is perfect for vehicle owners who thing that there vehicle is being vandalised or burglarised. The timer can also be set to record for any length of time the user designates whether it be ten minutes or three hours. The recording quality can also be programmed by the user as well. Each camera input can be programmed to record in a certain file type (AVI, FLM, MSV) and the recording time length can be set to allow the DVR system to record files to a certan time length. This will prevent the system from recording too large of files and make it easier to review when playing back the recordings. The frame rate can be adjusted between 30 FPS for NTSC and 25 FPS for PAL TV systems and the audio recording rate can also be adjusted from low to high quality. Brightness, contrast, hue and saturation san also be adjusted individually between each camera input. This way if you have a camera that is on the inside of the vehicle and the picture needs to be brighter to see inside, you can adjust the picture quality on that specific camera without affecting any of the other channels.

  • Other useful features of the CDR-520 are the built-in G-Sensor which forces the system to begin recording to an accident. When the G-Sensor is triggerd, the recordings are autmatically write protected and cannot be deleted over-written until the user manually deletes them from the system or backs them up onto the USB device. The G-Sensor sensitivity can be increased or decreased to allow the unit to start recording based on how high or low the G-forces are. The system also has motion sensing to allow automatic recording is any motion is detected on any of the cameras. A speed sensor input to clock the vehicles speed during the recorded events. With the speed sensor hooked up, the user can set the syetem to record based on constant speed and distance. The system also has an "Overspeed" setting which allows the system to start recording if the vehicle travels over a certain speed. Last the CDR-520 system has a series of alarm triggers which can trigger the system to activate and begin recordng with the door trigger, turn signals and brake pedal.

  • The CDR-520 comes includes with a full-functional remote control to navigate and change the settings of the system. It also includes a viewer software to download onto you computer. This viewer will allow the user to view the recordings on their computer when the SD card is retrieved from fhe system. The viewer not only shows the recordings from the system but also displays the G-Sensor and Speed Sensor information from the system as well.
