Good to know before you buy
!
The 24 hour parking monitor needs the ROVE Ultimate USB Type-C hardwire kit. The kit is sold apart from the camera and wires to the fuse box. Add it if you want the camera to watch the parked car manual.
!
The rear camera is made to mount inside the car. ROVE states that it is not waterproof. Fit it on the inside face of the rear window, over the electrostatic film manual.
!
There is no internal battery, so the camera stays plugged in. A supercapacitor holds charge for about 2 seconds, enough to save the last file. Use ROVE's car charger or a 5V 1.5A USB charger, and never wire the camera straight to the battery manual.
!
Connect the rear camera while the front camera is turned off. ROVE warns that plugging it in with the front camera on may damage the rear camera manual.
!
Format the card in the camera before the first drive. ROVE asks for this to prevent errors, and suggests a fresh format every 3 months manual.
Before you start
ROVE says a camera that freezes, lags or stops recording points to the memory card, not the camera.
How the Rove R2-4K Dual compares
Rove R2-4K Dual vs Rove R2-4K Pro
The Dual adds the rear camera, a bigger screen and the STARVIS 2 sensor. The R2-4K Pro covers the road ahead with a 2.4 inch screen and the earlier STARVIS IMX335 sensor ROVE.
Both are front and rear cameras built on a Sony STARVIS 2 sensor, with 4K front and 1080P rear video. REDTIGER lists a wider 170 degree front lens, a 3.18 inch screen and card support up to 256GB REDTIGER.
Does the Rove R2-4K Dual record when the car is off?
Yes, with the ROVE Ultimate USB Type-C hardwire kit fitted. That kit feeds the camera from the fuse box after the engine stops, which is what the 24 hour parking monitor runs on manual.
ROVE offers three parking modes in Video Settings›24HR Auto Parking Mode. Time lapse records at 1 frame per second, motion detection records when something moves in view, and collision detection waits with the camera off. In every mode, a hit above your set G-sensor level saves a locked 1 minute video in the Events folder.
The parking G-sensor has 9 levels, where 1 reacts to the smallest knock and 9 waits for a larger one. Next time you start the car, the camera says "parking mode got activated while you were away".
Will the Rove R2-4K Dual drain the car battery?
The hardwire kit watches the battery voltage and cuts power to the camera at the level you pick hardwire kit manual. For a 12V battery the four settings are 12.4V, 12.2V, 12.0V and 11.8V.
The kit detects a 12V or a 24V supply on its own and carries a 2A fuse.
Note
ROVE says to wire the kit to the fuse box, never straight to the battery terminals.
Does the Rove R2-4K Dual record audio?
Yes. The camera has a built in microphone and speaker, and Record Audio is on by default manual.
Press UP while the camera records to mute or unmute the microphone. Set Record Audio to off in the video settings for silent video every time.
Does the Rove R2-4K Dual have GPS?
Yes, the GPS module sits inside the camera, so nothing lives in the mount ROVE. It writes your route, location and speed into the video, and drives the live speed and compass on the home screen.
Four stamps sit at the bottom of the picture, and all are on by default: date and time, speed, GPS location and logo. Speed shows in MPH by default, and KM/H is in the same menu.
ROVE's free GPS Player for PC and Mac plays the video beside the route on a map, with the speed, the direction and the G-sensor trace manual.
How do the Wi-Fi and the ROVE app work?
The camera makes its own Wi-Fi network for your phone, so it pairs the way a speaker pairs over Bluetooth manual. Hold Emergency Lock for 2 seconds to turn Wi-Fi on, then join the network named ROVE_R2-4K-DUAL_****** with the password 12345678.
Install the ROVE Dash Cam app for iOS or Android and register a free account while your phone still has internet. The app then gives you live preview, settings, playback, downloads and over the air firmware updates.
The 5GHz band is the default and carries files faster. ROVE lists 2.4GHz for older phones, and a range of about 10M.
Is the Rove R2-4K Dual good at night?
ROVE builds the night picture around the Sony STARVIS 2 IMX675 sensor and an F/1.5 front aperture. ROVE says the sensor improves low light clarity, for sharper night details such as license plates and road signs ROVE.
High Dynamic Range is the second half of it, and it is on by default. HDR merges an overexposed and an underexposed frame, which widens the range of light held in one picture manual.
