4K frontSupercapacitorCPL included

The V1-4K is Rexing's long-running budget single-channel camera and it is the heat-tolerance outlier of this catalog: Rexing rates its supercapacitor from -4 to 176 degrees Fahrenheit, matching BlackVue's flagships at a fifth of the price. In a car that sits in an unshaded lot in Arizona or Texas, that number is worth more than most of the specifications above it. The camera records 3840x2160 at 30fps on a 170-degree lens, which is the widest here alongside the Redtiger and gives about 23 horizontal pixels per degree. A CPL filter is included. What Rexing does not publish is the image sensor, which means the 4K claim cannot be checked against a part number the way it can on the Sony-sensor cameras here - a meaningful caveat given how many budget cameras upscale. There is no HDR, GPS is an accessory module rather than built in, Wi-Fi is 2.4GHz, and parking mode requires Rexing's smart hardwire kit.

Best for

A car that bakes in an unshaded lot, on the smallest sensible budget.

The description and the pros and cons above are written from published specifications, not from owner reports. Owner sentiment, where we have it, is in its own section below.

What the numbers mean here

The front camera records 3,840 horizontal pixels across a published 170-degree field of view, which is 22.6 pixels per degree — plate-legible a few lengths ahead. There is no rear channel on this model. How this is calculated, and what it does not tell you.

It runs on a supercapacitor rather than a lithium cell, so there is no battery to swell in a car parked in summer sun — the classic way a windshield-mounted camera dies. The maker publishes an operating range of -4°F to 176°F. Supercapacitors and heat.

Records continuously at a reduced frame rate, or only once motion or an impact is detected. You get context, at one to three frames a second. The hardwire kit is a separate purchase, which is the line item people forget when budgeting. What each parking mode records.

Features

3840x2160 at 30fps on a 170-degree lens
Supercapacitor rated -4 to 176 degrees Fahrenheit
CPL filter included
2.4-inch screen and a suction mount
2.4GHz Wi-Fi, microSD to 512GB
Optional GPS logger module

Where it is strong

176 degrees Fahrenheit is the joint-highest heat rating in this catalog, at a fifth of the price of the cameras that match it
CPL filter in the box on a hundred-dollar camera
512GB card support and a screen, both unusual at this price
The suction mount makes it easy to move between vehicles or take inside

Where it gives way

Rexing does not publish the image sensor, so the 4K claim cannot be verified against a part number
170 degrees gives about 23 px per degree, so it resolves less per degree than several 1440p cameras
No HDR, so a low sun or a tunnel mouth will blow out
GPS is a separate module, and Wi-Fi is 2.4GHz only
A 2019 design still sold at its original price

What owners say

Summarised from public owner discussion. Nothing here is our own testing.

The V1-4K is a long-lived budget camera and the owner record reflects both halves of that. It has been maintained - a firmware update fixed a recording fault for at least one owner - and the hardwire kit works across the Rexing range, so people who upgrade keep their wiring.

Almost everything owners raise is about living with it day to day. App playback is the loudest: two or three seconds of video then nearly a minute of buffering, which owners have tried to fix with firmware updates, holding the phone closer and third-party apps, without success. Files with blank thumbnails and 'unable to play video' errors turn up, and memory errors mean periodic reformatting is part of ownership. The windshield mounting clip stops holding after a couple of years and is not sold separately.

The install trap is worth flagging: the hardwire kit ships with standard-size fuse taps, and many modern cars use mini or low-profile fuses. Owners have ended up soldering adapters onto the kit to make it fit. Check your fuse type before you start.

What owners like

A firmware update has fixed reported problems for owners, so Rexing does maintain the model
The hardwire kit works across several Rexing products, so an owner upgrading within the range keeps the wiring
Owners with two large batteries run it in parking mode for about five days without trouble
Cheap enough that owners equipping several cars price it per vehicle including card and hardwire kit

Common complaints

Owners find the camera plus its hardwired parking-sensor box takes up an unreasonable amount of windshield
Sun glare gets picked up in recordings, which is what the included CPL filter is supposed to prevent
App playback buffers for nearly a minute after two or three seconds of video, and owners have tried firmware, phone proximity and third-party apps without fixing it
Files with blank thumbnails and 'unable to play video' errors turn up, with memory errors requiring periodic reformatting
The windshield mounting clip stops holding after a couple of years and cannot be replaced separately
The hardwire kit ships with standard fuse taps that do not fit many modern cars, so owners end up soldering on mini or low-profile adapters

What owners of the Rexing V1-4K ask

Why does app playback buffer so badly?

Owners describe two to three seconds of video followed by nearly a minute of buffering, and report that firmware updates, holding the phone next to the camera, disabling cellular data and third-party apps all fail to fix it. Pulling the card and playing files on a computer works fine - that is the route owners settle on.

Will the hardwire kit fit my car?

Check your fuse type first. The kit ships with standard-size fuse taps and many modern vehicles use mini or low-profile fuses, so owners have had to solder on the right adapters. Buying the correct fuse taps separately before you start saves an afternoon.

The mounting clip stopped holding. Can I replace it?

Owners report the windshield clip losing its grip after a couple of years and finding no separate replacement available, which effectively ends the camera's life for some of them. A third-party suction or adhesive bracket sized to the camera is the only workaround people find.

Why do I keep getting memory errors?

Owners describe reformatting the card periodically as part of ownership, with blank thumbnails and 'unable to play video' appearing between reformats. A high-endurance card helps but does not eliminate it. Copy anything important off the card the day it happens rather than trusting the camera to keep it.
