In today’s fast-moving world, vehicle safety and monitoring have become more important than ever. Whether you manage a fleet of trucks, run a public transport service, or just want complete peace of mind for your personal vehicle, having a reliable mobile video recording system is essential.
One of the best solutions available today is the 4G MDVR & 4G SD Card MDVR with LAN connectivity that allows you to connect up to five cameras at the same time. This system is built to record high-quality video, store it securely, and even transmit it live using 4G technology.
In this blog, we’ll explore how this powerful 4G MDVR works, its key features, benefits, and why it is an excellent choice for anyone who wants real-time, reliable, and flexible vehicle monitoring.
What is a 4G MDVR?
A 4G MDVR (Mobile Digital Video Recorder) is a special type of video recording device designed for use in vehicles. Unlike standard DVR systems that are used in buildings, an MDVR is built to handle the vibration, temperature changes, and power fluctuations that happen inside moving vehicles.
The 4G in its name means that the MDVR can connect to mobile networks, just like a smartphone. This allows it to send live video, GPS location, and alerts to a remote server or a mobile app. You can check your vehicle in real time from anywhere in the world, as long as the MDVR has a 4G SIM card and a data plan.
When paired with multiple cameras, a 4G MDVR can record every angle around your vehicle—front, rear, sides, and even inside the cabin.
What is an SD Card MDVR?
An SD Card MDVR is simply an MDVR that can store its recordings on an SD card. This is very useful because SD cards are small, easy to replace, and don’t require complex installation like a traditional hard drive.
In many cases, an SD Card MDVR will also support a hard disk drive (HDD) or solid-state drive (SSD) for larger storage, but having an SD card option means you can quickly remove and replace the card when you need to back up or review footage.
For fleet managers and drivers, this makes it easy to keep track of video data without needing to remove the entire recording unit from the vehicle.
Why Choose a 4G SD Card MDVR with LAN Cable Support?
This particular 4G SD Card MDVR has an extra advantage—it supports LAN (Local Area Network) connectivity through a cable. This means you can connect it directly to your network or other devices for fast, stable data transfer.
Here are some reasons why LAN connectivity is so useful:
-
Faster video downloads – If you need to back up several hours of high-definition footage, doing it over 4G can take time and consume mobile data. With LAN, you can transfer files quickly.
-
Stable connection – Wired connections are less likely to drop compared to wireless.
-
Easy setup for fixed vehicles – If your MDVR is in a bus, truck, or train that returns to a central location every day, you can connect it to your depot’s network and transfer recordings automatically.
Connect Up to 5 Cameras for Maximum Coverage
One of the biggest benefits of this 4G MDVR is that it allows you to connect five cameras. This gives you complete coverage around your vehicle.
Here’s how many users set it up:
-
Front Camera – Captures the road ahead, useful for accident evidence and monitoring driving habits.
-
Rear Camera – Monitors traffic behind the vehicle, helpful for reversing and preventing rear-end collision claims.
-
Side Cameras (Left and Right) – Keep an eye on blind spots and protect against side impacts.
-
Cabin Camera – Monitors driver behavior and passenger activity, useful for taxis, buses, and ride-sharing services.
With all five cameras recording at the same time, you get a full, 360-degree view of your vehicle’s surroundings.

How a 4G SD Card MDVR Works in Real Life
Let’s imagine you manage a fleet of delivery trucks. Every truck has this 4G SD Card MDVR installed with five cameras. As your drivers go about their deliveries:
-
The front camera captures road conditions and any incidents.
-
The rear camera helps with safe parking and reversing.
-
The side cameras make sure blind spots are monitored.
-
The cabin camera ensures the driver is following company policies.
All this footage is stored on the SD card and hard drive. If you need to check on a driver in real time, you can log in through the 4G connection and view live video. At the end of the day, when the trucks return to the depot, you can connect the MDVR to your LAN and quickly download the day’s recordings.
