    Almost all standard dual-channel (front and rear) dashcams operate using a two-cable layout at the vehicle level: one power cable supplying the main front camera (via a cigarette lighter adapter or hardwire kit), and a single interconnecting cable running from the front camera back to power and feed video data to the rear camera.

    In other words, the rear camera itself never needs a separate independent connection to your car's fuse box or power supply —it relies completely on that one single tether running from the main front unit. Popular and reliable models featuring this single-wire rear connection include:

    • VIOFO A229 Plus / Pro : Uses a very slim, coaxial rear connection cable running from the main unit to the back window for both power and high-resolution video.
    • Redtiger F7N / F9 : Standard dual setup where a single rear cord plugs directly into the front camera port.
    • Garmin Dash Cam Tandem / 67W with rear accessory : Compact setup configurations utilizing centralized front power routing.

    To help narrow down the exact model for you, could you let me know:

    • What is your target budget?
    • Do you prefer a discreet stealth shape or a smart screen/mirror dashcam format?

    I will provide a tailored recommendation based on your preferences.

    If you want a dashcam with a rear camera connected by one cable that carries the rear-camera video signal, I'd focus on dual-channel systems with a single coaxial cable or combined power-and-video cable. That means you don't need to run a separate power cable all the way to the rear camera.

    One important distinction: the rear camera's connecting cable is separate from the power cable that supplies the front dashcam. Most wired dual-camera systems still need both connections.

    Best options to consider

    What must the cable do?

    One cable carries both power and video to the rear camera

    One thin cable connects the rear camera to the front unit; separate front power is fine

    No cable running to the rear camera at all

    Budget

    Under $150

    $150–$300

    $300+

    Where will the rear camera go?

    3. 3VIOFO A229 Pro 4K+2K

    Virtually all dual-channel (front and rear) mainstream dashcams operate on this exact principle: the rear camera connects to the front main camera using a single interconnecting cable , which supplies both power and video data. The front camera then plugs into your car's power source (cigarette lighter or fuse box).

    Top-tier, highly reliable options featuring this clean, single-cable rear setup include:

    • VIOFO A229 Pro / Plus (or A129 Plus Duo ): Widely praised for exceptional video clarity using Sony STARVIS 2 sensors . The rear camera connects to the front unit via a single slender, easy-to-hide coaxial cable.
    • Thinkware F200 Pro or U3000 : Excellent for reliability and clean discreet styling, utilizing a single proprietary video/power cable running from the rear glass to the main front camera.[1][2]
    • Vantrue N4 Pro / N2X: A 3-channel or 2-channel powerhouse that routes the rear camera feed into the primary front unit through one single rear-camera wire.

    If you'd like to narrow this down, let me know:

    • Your budget range
    • Whether you prefer 4K resolution or are happy with 1080p/2K
    • If you need parking mode (requiring hardwiring)

    2. 2VIOFO A229 Pro 4K+2K

    Yes. If your goal is a clean installation with a rear-facing camera and only one cable plugged into the front dashcam, there are a few good options. The key distinction is that most dual-camera systems use one cable to power the front camera and a second cable to connect the rear camera. A smaller number of systems use a separate recording module to keep the front camera's wiring cleaner.

    1. BlackVue DR970X-BOX-PLUS 2CH

    (Best for a clean install)

    Premium · 4K front camera

    This system places the recorder in a separate, lockable box that can be hidden in the glove compartment or under a seat. That allows a cleaner setup at the front camera, with the rear camera connected to the recording unit.

    Best if you want minimal visible wiring near the windshield.

    2. VIOFO A229 Pro

    High video quality · 4K front, 2K rear

    A strong conventional dual-camera option with HDR and excellent low-light sensor technology. The rear camera connects to the front unit by cable, but the front unit also needs its own power connection.

    Best if image quality matters more than having a single plug at the front camera.

    One quick clarification

    When you say “only one cable,” which arrangement do you mean?

    A. Only one cable plugged into the front camera total — no separate power cable.

    B. One cable running from the front camera to the rear camera, carrying both power and video. A separate front power cable is fine.

    C. No cable running to the rear camera — wireless rear camera preferred.

    [Find the best match]

    That distinction matters because option A is much more restrictive than option B, and I want to recommend a system that actually meets your wiring requirement.
