The IMX678 is a high-performance image sensor developed by Sony for advanced 4K imaging applications, known for using stacked STARVIS 2 technology to improve image quality and reduce noise, even in low-light conditions.

The sensor features higher resolution, enhanced HDR (High Dynamic Range) capabilities, and fast autofocus performance, making it suitable for use in devices like smartphones, security cameras, and dash cameras.

eMMC 5.1 (Embedded MultiMediaCard) is a type of internal storage commonly used in smartphones, tablets, but F77 innovatively uses it as a built-in storage for dash cam.

It integrates both flash memory and a flash memory controller in a single package, making it compact and efficient.

eMMC 5.1 is much higher than traditional SD cards in various parameters. Some key parameters of eMMC 5.1 include:

• Sequential read speeds: up to 240 MB/s, 10x faster than SD card.
• Sequential write speeds: up to 160 MB/s, 10x faster than SD card.
• Lifespan: up to 100,000 Read/Wirte,
  10× more durable than SD cards.
• Capacity: typically ranges from 16 GB to 256 GB.

No, the F77 comes with 128GB/256GB of free built-in storage, just like when you purchase a 128GB/256GB phone or tablet. In principle, the F77 does not require an additional SD card.

However, the F77 has an SD card slot, which is useful for customers who need to transfer recorded videos to a SD card as backups, and it also supports reading and playing videos from the SD card.

Please connect the included Hardwire Kit to your vehicle's fuse box. This allows the Dash Cam to protect your vehicle while parked without draining your battery.

Please refer to this blog for instructions on installing your Hardwire Kit:

No, the 4K rear camera of F77 is not waterproof, so please install it inside the of the car, usually on rear windshield.

The F77 host can use the power cable of other models of redtiger dashcams (such as F7N series products), but their rear cameras are not compatible. This means that if you directly replace the originally installed dashcam with F77, the 4K rear camera will not be available. We recommend that you re-arrange the cables.

Sure, the front and rear dual cameras can record and display the images on the screen at the same time.

Installing the Hardwire Kit is a prerequisite for you to activate the parking monitoring function. If you do not install the Hardwire Kit, the parking monitoring function will not work. If you find it difficult and troublesome to install, you can go to a car repair shop and ask a professional to install it for you.
