Bright and sharp 5 in. IPS display mirror dash cam with a backup camera. Comes with all-weather compact camera that can be mounted at the back of your vehicle. Rear camera not only helps you when you’re backing up, but it also records the road behind you. DR 3302 mounts atop of original rearview mirror with rubber band fasteners in a few seconds. Its built-in shock sensor can detect impacts, hard breaking or rapid acceleration to lock current segment. Locked segments never get overwritten so the evidence will stay on your memory card even if you continue driving for a long period of time. With parking monitoring on, DR 3302 turns on and starts recording if it detects the car was hit. After taking short video, it turns off again to conserve its battery. Two cameras help identify offender in hit-and-run or vandalism cases, even if intruder approached from the rear. Excellent low-light performance, dual lens, powerful features and discreet appearance make DR 3302 an obvious choice for enthusiast and professional drivers.
