The thing they wanted to see was tiny. A plate on a car already three lengths ahead. Whether the light was amber or red. Which lane a van started from.\n\nThat is the case for 4K at the front. More pixels across the same view give you more to work with when you pause and zoom. This guide walks through what this 4K dash cam front and rear offers, what the maker leaves unsaid, and how to decide whether it suits your car.\n\nTwo cameras, two jobs\n\nThe set has a front unit and a rear camera, and they record together. The front camera records 4K, also written as 2160p. The rear camera records 1080p.\n\nThat split makes sense. The road ahead is where you need to read detail at a distance. The view behind is mostly about what was close to you and how it moved. A 1080p rear camera handles that well and keeps file sizes down.\n\nThe product details list lens angles of 160 and 155 degrees without saying which lens is which. Either way, both are wide enough to take in the lanes beside you.\n\n5GHz WiFi without the jargon\n\nA dash cam's WiFi is not for the internet. It is a short link between the camera and your phone, used by the app.\n\nMany dash cams use the 2.4GHz band for that link. It works, but it is slow with big files, and 4K files are big. This camera uses 5GHz. The maker states transfers of up to 8 MB/s and says that is up to four times faster than a 2.4GHz dash cam.\n\nIn daily use, this decides whether you bother with the app at all. With a slow link, people end up pulling the card out and finding a reader. With a faster one, you stand by the car, download the clip and go.\n\nTwo practical notes. Your phone needs to support 5GHz WiFi, which most recent phones do. And 5GHz WiFi has nothing to do with 5G mobile data. There is no SIM card and no data plan.\n\nThrough the app, the maker says you can watch a live view, change settings and download recordings.\n\nSensor, lens and WDR\n\nThe maker says the camera uses a Sony IMX sensor, with a lens of six glass elements and an f/1.6 aperture. No sensor model is given, so take that as the maker's description.\n\nWDR is the more useful term to understand. It stands for wide dynamic range. Singapore roads throw up hard contrast all day: deep shade under a flyover with bright sky beyond, the mouth of a tunnel, wet tarmac reflecting headlights after an evening storm. WDR balances the bright and dark parts so both keep some detail.\n\nThe product details also list 30 and 60 frames per second. The maker does not say which resolution each applies to, so check the settings when the camera arrives.\n\nLoop recording and the G-sensor\n\nYou should never have to manage a dash cam's storage. Loop recording takes care of it by replacing the oldest videos when the memory is full.\n\nThe risk with any loop is losing the one clip you needed. The 3-axis G-sensor is the answer to that. It senses an unusual shock in any of three directions and saves the clip from that moment so the loop cannot delete it. The feature list calls this automatic event detection.\n\nStill, make a habit of it. If something happens, download the clip to your phone that day.\n\nThe memory card: please confirm the size\n\nA microSD card is included, which is welcome. The size is where the maker's own details disagree.\n\nThe contents list names a 64GB card. A later note from the maker says that from 9 June 2026 the included card was changed to 32GB. We cannot tell you which one will be in your box, so please confirm the card size with us before you order.\n\nWhatever arrives, the camera supports cards up to 256GB. If you drive a lot, a larger card is a sensible upgrade, because 4K fills a small card quickly.\n\nNo battery, and what that means\n\nThe maker is direct about this. The camera has no built-in battery, and it turns off at once when it is disconnected.\n\nFor daily driving this is no problem. The included car charger plugs into the 12 V socket, and the camera runs whenever the socket has power. It does mean two things. Do not unplug it to charge a phone and forget to plug it back in. And do not expect any recording after the engine is off unless you add the hardwire kit.\n\nThere is an upside in a hot climate. Batteries dislike heat, and a camera without one has one less part to age in a car parked under the sun.\n\nParking mode needs extra kit\n\nParking mode is a real feature here, but it is not ready out of the box. A separate hardwire kit is required.\n\nWith the kit fitted, the maker says the camera switches to parking mode by itself after you park. You choose between two modes. One records only when a shock is detected. The other is time-lapse, which records all the time at a low frame rate so that many hours fit on the card.\n\nA hardwire kit connects to the fuse box. If you park in a busy multi-storey car park every night and want that coverage, budget for the kit and for an installer.\n\nThe small things: screen, voice and sound\n\nThe front unit is 2.5 x 5.1 x 7.6 cm, silver, with a listed weight of 300 g. It has a 1.5 inch screen. That is a status display more than a viewing screen, and the product details give the app as the control method.\n\nVoice prompts are listed, though the maker does not say in which languages. A built-in microphone is listed too, so the camera can record sound. The manual is included, but the maker does not promise an English version.\n\nFitting it in a Singapore car\n\nSingapore drives on the left, with the driver on the right. Mount the front unit high on the windscreen, behind or beside the rear view mirror, where the wipers sweep. A camera looking through a patch the wipers miss is not much use in a monsoon shower.\n\nThe adjustable bracket lets you tilt the lens after it is fixed. Use the app's live view to level it. The wiring tool in the box helps push the cable under the roof lining and down the pillar towards the socket. The rear camera cable runs to the back along the roof lining. The maker does not state its length, so ask us if you drive a long vehicle.\n\nSetting it up on day one\n\nDo the setup in a covered car park, out of the sun, with the engine running so the socket has power. Plug the camera in before you fix anything. Join its WiFi from your phone, open the app and bring up the live view.\n\nNow hold the front unit in place and look at the phone. You want the horizon level and roughly in the middle of the frame, with a thin strip of bonnet at the bottom. Check the rear camera the same way before you commit to a spot.\n\nNext, set the date and time, choose the resolution and look for the microphone setting. Format the card in the camera. Then fix the bracket, tidy the cables and take a short drive. Download one clip over the 5GHz link when you get back. If that clip plays on your phone, the whole chain works.\n\nHeat and care\n\nThe maker gives no operating temperature. Park under cover when you can and use a windscreen shade in open lots. Wipe the lenses with a dry microfibre cloth, and clean the inside of the glass too. Reformat the card in the camera now and then, and replace it if you start seeing errors. Cards wear out with constant writing.\n\nOne more thing. Recording other people is covered by Singapore law, including the PDPA.\n\nWho should buy it\n\nIt suits drivers who care about front detail, who want quick downloads to a phone, and who like a camera with no battery to worry about. The listed vehicle types are saloons, SUVs, trucks and mini vans.\n\nLook elsewhere if you need GPS, which the maker does not state, or if you want parking recording without fitting extra hardware.\n\nThe short version\n\nA 4K front camera, a 1080p rear camera, 5GHz WiFi for fast downloads, WDR, loop recording and a 3-axis G-sensor.
