REDTIGER F7NX 4K Front and Rear Dash Cam: features, specs and who it suits

The REDTIGER F7NX is a two-camera dash cam that records the road ahead in 4K and the view behind in 1080P. It has a 3.18-inch touchscreen, built-in Wi-Fi and GPS, and a 128GB memory card in the box. Here is what its main features mean.

Front and rear recording

The front camera records at 4K and the rear at 1080P, with a 170° wide-angle view. REDTIGER lists a Starvis sensor, WDR (wide dynamic range) and an f/1.5 aperture with a six-layer glass lens. In general terms, a wide aperture lets in more light for night footage, and WDR balances very bright and very dark areas in one frame, such as a tunnel exit or headlights at night. A 4K front view gives more detail for reading registration plates and road signs than lower resolutions, though results still depend on conditions.

Wi-Fi, app and voice control

The camera has built-in 5.8GHz and 2.4GHz Wi-Fi and works with the REDTIGER app on iOS and Android. REDTIGER says you can view and manage recordings on your phone and share clips. The 5.8GHz band typically transfers large video files faster than 2.4GHz, which matters with 4K footage.

For hands-free use there are 12 voice commands, and a 3.18-inch touchscreen replaces most physical buttons. REDTIGER says this lets you stay focused on the road.

Loop recording and storage

Loop recording means that when the card is full, the camera overwrites the oldest footage so it keeps recording without you clearing space. A 128GB card is included. How many hours it holds depends on the resolution and the rear camera, since 4K files are large. Events such as a sudden impact are normally locked so they aren't overwritten; the listing refers to a G-sensor, so check the manual for how it protects clips.

Parking mode

REDTIGER describes two parking-mode options: time-lapse recording, which condenses long periods into less footage, and collision detection, which starts recording when an impact is sensed. The listing notes that an additional hardwire kit is needed for parking mode and the G-sensor feature to work, so factor that in if you want recording while the car is off.

Mounting and warranty

The camera attaches with a 360° suction cup mount with strong adhesive, which REDTIGER says suits tilted or vertical windshields. The listing mentions an 18-month guarantee and phone and email support, with replies promised within 24 hours. The listed dimensions are 3.1 x 1.6 x 2.4 inches (about 7.9 x 4.1 x 6.1 cm).

Who it suits

A dual-channel dash cam suits drivers who want a record of events ahead and behind, such as commuters, rideshare drivers and anyone parking on the street. The built-in GPS can add location information to footage, depending on the settings.

What to check before you buy

• Local rules: laws on windscreen mounting and on recording vary by region. Check what applies where you drive.
• Fit: make sure the front unit and rear camera cable can be routed neatly in your vehicle.
• Parking mode: confirm you have the hardwire kit and a suitable power source if you want it.
• Card care: memory cards wear with constant recording; check the manual on formatting and replacing them.
• Rear view: think about where the rear camera will sit and whether the cable reaches.
