Great deal: 4K car camera with decent image quality and GPS module discounted to under 3 thousand!

A dash cam in a car has become essentially a necessity in the last few years — insurance companies increasingly welcome it when resolving accidents, and in case of a dispute with the other party, the recording is invaluable. The NAVITEL R99 4K is available on Alza for 2,792 CZK after applying the code ALZADNY20. From the original 3,490 CZK, this is a drop of 700 crowns, and in the segment of 4K cameras with a GPS module and Wi-Fi, it is one of the most affordable options.

Quick summary:
✅ Makes sense if you need an affordable camera with quality 4K image. The Sony IMX415 sensor and integrated GPS module with radar alerts are good value at this price point.
⚠️ Consider that according to many reviews, the camera has a poor app and extremely slow transfer of recordings via Wi-Fi. Downloading a five-minute video to your phone typically takes 10 minutes, so if you want to transfer videos to your mobile, keep this in mind.
💡 For 2,792 CZK you get a Sony IMX415 sensor, 4K (3840 × 2160) at 30 fps or 2K at 60 fps, 140° viewing angle, 3.18″ IPS touchscreen display, integrated GPS module, Wi-Fi, support for microSD cards up to 256 GB, parking mode (requires a separate NAVITEL SMART BOX MAX), G-sensor, supercapacitor instead of a battery, and a free one-year license for Navitel Navigator navigation.

What the camera does well

The main advantage — quality image day and night. The Sony IMX415 is a proven sensor for dash cams, and reviews repeatedly state that it reads license plates well even in motion and in poor lighting conditions. The seven-layer glass lens with an infrared layer helps at night, where the camera can distinguish details even in city traffic with mixed lighting. If you prefer fluidity over detail, you can switch to 2K at 60 fps or Full HD at 120 fps — for situations where you want to capture fast maneuvers.

The second useful feature is the integrated GPS module, which, in addition to recording location and speed, reports approaching speed cameras and average speed zones. The database contains many locations in the Czech Republic and neighboring countries, although several reviewers point out that the accuracy is not 100% — sometimes it reports radars that are not there, other times they are missing. In Austria and Hungary, according to users, the database is very poor.

The third strong point — supercapacitor instead of a battery. Classic lithium-ion batteries cannot handle summer heat in a car, where temperatures behind the windshield reach 70 °C and more. A supercapacitor has no problem with this, so the camera should easily survive several years of operation. The design further helps by replacing the battery with it — thus, there is no component that could swell or stop holding capacity.

The 3M adhesive pad holds firmly according to reviews, the touchscreen display is relatively intuitive, and the package includes a car charger with a second USB-C port for charging a phone — a small detail, but practical.

What to expect

There are a few things here. First — the NAVITEL DVR Center app is systematically criticized in reviews. Reviewers describe it as “retarded,” “like a school project,” or “from 5-year-old software.” The main problem is the extremely slow transfer of videos via Wi-Fi — a five-minute video takes 10 minutes to download, and a two-hour journey is practically impossible to transfer. If you absolutely need the recording on your phone, most people choose to remove the card and copy it to a PC via a card reader.

A second problem, pointed out by users of Octavia 4 and similar modern cars — the camera has a USB-C port, but it does not work with a double-sided USB-C cable. It requires a USB-A cable and a USB-C adapter. This means that if you only have a USB-C socket in your car, you need an adapter. A silly design flaw that reviewers repeatedly mention.

Third thing — the camera heats up. Essentially all reviewers mention this, and several of them are concerned about summer operation. The manufacturer claims it’s within safe parameters, but after a year of use, a few reviewers reported a malfunction or inability to start the device.

Minor caveats — the camera angle cannot be adjusted smoothly, only in steps. The audible alerts for speed cameras and speed limits are quite loud and annoying at default settings, but can be turned off. Parking mode only works with the separately sold NAVITEL SMART BOX MAX — without it, the camera will not record anything when the car is parked. And the package does not include a memory card.

Do you have a dash cam in your car, or do you currently rely on witnesses and the insurance company?
