"Front + rear" dashcams such as the BlackVue DR750S-2CH do not have both lenses built in to one module. If the second camera lens is not built in to the main camera body, this 'remote' secondary lens may be placed just about anywhere throughout the vehicle, in most cases being mounted in the rear windshield and pointing out towards the rear (to capture events that occur behind the vehicle). This type of dashcam setup with a wide angle front-facing lens and wide angle rear-facing lens would give near 360 degree video coverage around your vehicle, for a truly comprehensive backup eyewitness. Please see the following diagram for where the two dashcams of a "front + rear" dual-lens dashcam system are typically placed in your vehicle:
Who might want to use a "front + rear" dashcam?
Being able to capture footage of the front and rear exterior of your vehicle is a huge benefit to those involved in in traffic accidents. In an insurance claim, being able to provide video documentation of what actually occured can be the difference between winning and losing. These dashcams are also great for the adreneline junky or the racecar driver to capture high-quality footage of the fun! Even if you're parked, you can keep an eye on your vehicle when it's bumped or vandalized. Whether you're a hobbyist or you simply want an extra layer of security on your daily commute, a "front + rear" dashcam can give you what you need.
