Car & Driver's Road Patrol Touch Duo boasts an impressive array of features, including an OLED touchscreen interface and flexible camera setup. However, some annoying quibbles spoil the experience, and some features don't work as well as they should.

Nevertheless, with decent image performance and an all-in-one package for most camera requirements, the Road Patrol Touch Duo is a worthy all-rounder. [The Road Patrol Touch Duo is available from Costco.com for $139.99.

The design of the Road Patrol Touch Duo is nothing to write home about. It looks like a half clamshell, with a red C-shaped LED around a volumetric lens. The unit itself, however, feels cheap, light, and plasticky.

The wide display on the back corresponds to a rather thick bezel, and the housing forms a secondary border, giving the unit a much larger off-screen area.

This is not to say that large displays are not welcome. However, the combination of the large unit, the removable rear camera module on the underside, and the tall mount means that this dash cam occupies more windshield area than we would like.

In addition, the Road Patrol Touch Duo offers a surprising number of other features and add-ons, including a bundled 16GB microSD card and a choice of adhesive or suction mounts.

Next, a parking warden monitors the perimeter 24/7 (if there is a hardwired connection) and starts recording when an accident is detected. An on-board G-sensor also activates after a collision, automatically protecting the current footage.

The Road Patrol Touch Duo has a touchscreen feature that many dash cams lack. This model also has a 3-inch OLED screen.

If this is not enough, the Touch Duo has a driver assistance mode with lane departure and collision warning detection systems. When we tested both of these functions, the lane departure system worked quite well, but the latter proved to be too sensitive, sending incessant rasping alerts, especially in city driving, and quickly ran out of patience. Moreover, there is no way to turn off one function and leave the other on. Believe me, you're better off leaving it off.

The Road Patrol Touch Duo's touch screen makes setup a breeze. You can tweak the time and date settings, recording duration, etc.

The rear camera module is also versatile. It can be attached directly to the main unit to make a cabin camera, attached to a mount to make a rear camera, or tied to the rear headrest with a rubber band to make a blind spot camera or baby monitor.

Despite being a mid-budget model, the Road Patrol Touch Duo offers impressive 1080p image quality. Whether during the day or at night, images are generally crisp and clear.

Contrast is also excellent, allowing the camera to capture roads, clouds, and the sky clearly without any white noise. Also, at night, Road Patrol provides a clear view of the vehicle tag, road, and surrounding area, where other dashcam sensors may struggle in bright light or dark night (headlights often obscure the vehicle tag).

Additionally, the rear camera, while not as sharp as the front camera, makes a good effort. The performance is surprisingly excellent for a camera in this price range.

Sound is also decent on the Road Patrol Touch Duo, but the warning tone is sometimes too loud during playback. There is also a faint but unmistakable digital whine during playback that can be distracting.

The Road Patrol Touch Duo has a lot to offer, including flexible camera placement and touch screen functionality. Nevertheless, it is hardly a home run for Car & Driver, as some features are not worth turning on.

Other dash cams may look better and offer more standard features such as WiFi connectivity and GPS, but the Road Patrol is a solid mid-range unit with image quality that trumps many products.
