DNA DVR2CHS-4G 2K Front 4G Dash Cam with 3" IPS and 1080P Rear Camera

DNA DVR2CHS-4G 2K 4G Dual Dash Cam with 3" IPS and 1080P Rear Camera

A fully connected dual-channel dash cam with 4G LTE, GPS, remote live view, and parking mode alerts, the DVR2CHS-4G delivers 2K front and 1080P rear recording with smartphone access from anywhere.

Product Overview

The DVR2CHS-4G is DNA's 2-channel 4G LTE dash cam, combining a 2560x1440 front camera and a 1920x1080 rear camera with built-in 4G LTE connectivity, GPS tracking, and a 3-inch full-colour IPS display. The 4G LTE connection allows live footage to be viewed remotely, recordings to be accessed and downloaded, and real-time alerts to be received on a smartphone via the dedicated app, regardless of where the vehicle is located. The 2K front camera captures detailed footage at 2560x1440 at 30FPS across a 143° viewing angle, while the 1080P rear camera provides simultaneous dual-channel coverage at 1920x1080 at 30FPS across the same 143° field of view, connected via the included 8-metre extension cable with trigger wire.

Parking Mode monitors the vehicle when stationary. If motion or an impact is detected, the dash cam records automatically and sends a real-time alert to the owner's smartphone via 4G. The built-in G-Sensor detects sudden impacts and locks the associated footage to prevent overwriting during continuous loop recording. GPS records driving speed, route, and location data alongside video for full contextual evidence in the event of an incident. The 3-inch IPS display provides clear playback and settings navigation on the unit. A 32GB TF card is included and the system supports cards up to 256GB. A 12V hardwire kit is included for continuous parking mode power, and a 12V accessory power adaptor is also supplied. Note that a SIM card is required for 4G LTE connectivity and is not included.

Features & Benefits

4G LTE Connectivity for Remote Access: The built-in 4G LTE module allows live footage to be viewed remotely, recordings to be reviewed and downloaded, and real-time alerts to be received via the dedicated smartphone app from any location. A SIM card must be sourced separately and inserted into the onboard SIM card slot to activate 4G connectivity.

2K Ultra HD Front Camera: The front camera records at 2560x1440 resolution at 30FPS across a 143° wide-angle field of view, capturing number plate detail and road hazards with greater clarity than standard 1080P dash cam footage.

1080P Full HD Rear Camera: The rear camera records simultaneously at 1920x1080 at 30FPS across a 143° viewing angle, providing complete dual-channel coverage of both front and rear surroundings at all times during driving.

3-inch Full-Colour IPS Display: The 3-inch IPS screen provides sharp, colour-accurate playback and live view directly on the unit, as well as straightforward navigation of settings and recording modes without requiring a smartphone.

Real-Time Vehicle Status Alerts: Instant smartphone notifications are sent when the vehicle is turned on or off, providing awareness of vehicle use and an additional layer of security when the vehicle is unattended.

Parking Mode with Smart Alerts: When the vehicle is parked and powered by the hardwire kit, the dash cam monitors for motion and impact events, automatically recording triggered footage and sending real-time alerts to the owner's smartphone via 4G.

Built-in GPS Tracking: GPS records driving speed, route, and location data embedded alongside the video recording, viewable remotely through the app or alongside playback for a complete picture of any driving event.

G-Sensor and Emergency Lock: The built-in G-Sensor detects sudden impacts and automatically locks the associated video segment, preventing it from being overwritten by continuous loop recording so that collision footage is always preserved.

Continuous Loop Recording: When storage is full, the dash cam automatically overwrites the oldest unlocked footage, ensuring uninterrupted recording without requiring manual management of the memory card.

Hardwire Kit Included: The included 12V hardwire kit connects the dash cam directly to the vehicle's fuse box for continuous power supply, enabling parking mode without draining the vehicle's battery through the accessory socket.

32GB TF Card Included, Up to 256GB Supported: A 32GB TF card is included for immediate out-of-the-box use, and the system supports high-capacity cards up to 256GB for extended continuous recording time before the oldest footage is overwritten.

Frequently Asked Questions

Does the DVR2CHS-4G include a SIM card?

No. The DVR2CHS-4G includes a SIM card slot and built-in 4G LTE hardware, but the SIM card must be sourced separately. A compatible 4G LTE data SIM from a supported carrier is required to activate remote live view, real-time alerts, remote playback, and parking mode smartphone notifications.

What does 4G LTE connectivity allow me to do that Wi-Fi alone cannot?

Wi-Fi connectivity on a dash cam typically only functions when the smartphone is in close physical proximity to the camera, such as when parked next to the vehicle. The DVR2CHS-4G's 4G LTE connection allows remote live view, real-time vehicle status alerts, and parking mode notifications to be received and acted upon from any location with mobile coverage, making it suitable for fleet monitoring, vehicle security, and remote access when the owner is away from the vehicle.

How does parking mode work with the hardwire kit?

The included 12V hardwire kit connects the dash cam to a constant live fuse in the vehicle's fuse box, providing power to the camera while the ignition is off without drawing from the accessory socket. While in parking mode, the dash cam monitors for motion or impact events using the G-Sensor and motion detection. When an event is detected, the camera begins recording and sends a real-time alert to the owner's smartphone via 4G LTE.

What is the maximum recording capacity supported?

The DVR2CHS-4G supports TF cards up to 256GB. With a 256GB card and dual-channel 2K plus 1080P recording, the system can store a substantial amount of continuous footage before the oldest unlocked segments begin to be overwritten by loop recording. The 32GB card included in the box provides a practical starting capacity for most users.

Does the G-Sensor affect normal driving or bump detection while driving?

The G-Sensor sensitivity can typically be adjusted in the dash cam settings to reduce false triggers from minor road bumps and vibrations during normal driving. Setting the sensitivity appropriately for the vehicle and road conditions prevents normal driving inputs from unnecessarily locking large volumes of footage, which would reduce the effective loop recording storage available.
