4K Dash Cam vs Kustom Signals Police Rear-View Mirror Dash Cam: Which to Choose?

Deciding between a $34.98 4K front/rear dash cam with WiFi and a $185.99 used Kustom Signals rear-view mirror bundle? Here's how to pick.

Last updated Aug 15, 2026

Choosing a dash cam for your car often means choosing between two very different designs: a compact new camera designed to record in both directions, or a used camera lot. The two options come from opposite ends of the dash cam spectrum, so your decision depends on which trade-offs you're willing to accept. Both are worth considering depending on your priorities.

Quick Verdict

The 4K Dash Cam is the straightforward pick if you want a new, compact camera and a lower price. The Kustom Signals lot is the specialist choice if you want a used unit and are willing to spend more.

Where Each Product Wins

  • Kustom Signals lot: Wins on the all-in-one nature of the lot. The camera unit comes with more than just a single camera.
  • 4K Dash Cam: Wins on price and the breadth of the feature set offered for that price.

The Kustom Signals lot is for drivers who want a ready-to-go package. The 4K Dash Cam is for drivers who want a fresh, compact camera and care more about keeping costs down. Think about which trade-off you care about more: a used unit that comes as a complete package, or a brand-new camera with a full set of modern recording options. That distinction is the core of this comparison.

Product Notes

Kustom Signals Lot Dash Cam Police Rear View Mirror

This is a pre-owned lot from Kustom Signals in "Very Good Pre Owned Condition," including a set of accessories. If a rear-view mirror-style camera is what you're after-a unit that sits where your mirror normally goes-this bundle is built around that design. The included accessories are a notable part of the deal, giving you more than just a single camera. The limitation is that you're buying a used unit. If you want a mirror-mounted dash cam and don't mind a used unit, this lot gives you that specific setup with extras included.

4K Dash Cam Wifi UHD 2160p Front Rear Dual Camera

This DXcam unit is brand new and comes with a 3-inch screen, a 4K front camera, a 1080p rear camera, built-in WiFi, loop recording, and a 170-degree field of view. It also supports memory cards up to 256GB, but the memory card is not included-you'll need to provide your own. The compact size (just 2.36 inches wide and 2 inches high) means it doesn't take up much windshield space. The limitation is that it doesn't have a rear-view mirror housing, so if you specifically want that mirror-style look, this won't give it to you.

Final Choice by Use Case

Choose the Kustom Signals Lot Dash Cam Police Rear View Mirror if you want a used unit and you're comfortable spending more. Choose the 4K Dash Cam Wifi UHD 2160p Front Rear Dual Camera if you want a new, compact camera and a lower price is your priority. For most drivers, the 4K Dash Cam offers the simpler path to reliable daily recording.
