What is a Tamper-Proof Case for Dash Cams?

Designed for BlackVue dash cams

Protecting Your Dash Cam

From fender-benders to vandalism and unexpected road incidents, having a dash cam installed inside your car promotes truth and accountability.

Therefore, as the use of dash cam footage for legal, insurance, and professional purposes grows, so does the necessity to protect the device itself, especially from improper handling or theft. In this article, we will take a look at a dash cam accessory designed to keep your footage, and your dash cam safe and secure — tamper-proof cases.

What is a Tamper-Proof Case?

While your car needs a dash cam, your dash cam needs a tamper-proof case.

A Tamper-Proof case is designed to safeguard the key components of your dash cam through a base and cover piece securely held together by metallic screws. Two manufacturers that have Tamper-Proof cases are BlackVue and VIOFO.

This accessory is essential if you are needing to protect the recorded video data captured by the dash cam, as it protects the micro SD card slot, prevents unplugging of power and rear cable connectors, and secures the dash cam mount itself.

If you have a commercial fleet of cameras and drivers are not permitted to remove footage from the cameras, a Tamper-proof case can prevent unauthorized access to the dash cam's micro SD card. This is also applicable in securing your dash cam’s SD card to keep your footage private.

BlackVue & VIOFO Tamper-Proof Cases

The BlackVue Tamper Proof Case includes a special Allen key to fasten or loosen the device, and comes in two parts - the left piece and the right piece that perfectly fit your screenless, tubular BlackVue head unit. For X Series dash cams, the Tamper-Proof case also allows locking the angle of the front camera.

Meanwhile, the VIOFO Tamper Proof Case is exclusively available for the A139 and A139 Pro models. It comes in two packages: one with just the screw bracket for locking the memory card and the hardwire kit, and another including the rear and interior wires for three channel installations.

Wait, is there a dash cam with a built-in tamper-proof case?

While the standard BlackVue dash cams like the DR770X and DR970X series require a separate tamper-proof case, the 2023 BlackVue DR770X Box triple-channel dash cam system has this essentially built-in.

BlackVue developed the DR770X Box dash cam differently, including three small cameras for the front, interior, and rear, as well as the major event - the Box. This box is created independently of the cameras and houses the BlackVue dash cam's processor, WiFi connection, and memory card. Aside from the cameras being so small, the Box itself can be hidden in the glove compartment or under the seat.

The DR770X Box cannot be easily slid off of the mount, as the mount itself is firmly fastened and locked to the unit with a special Allen key included. Beyond that, the power cable and SD card slot are not accessible either, with its own tamper-proof locking cover, covering both. It features tamper-proof solutions on the main unit, and all cameras with the SD card hidden inside the box and locked behind its own unique key - so your dash cam security? Totally worry-free.
