Selecting the right Mobile Digital Video Recorder (MDVR) for your fleet is a critical decision that can directly impact the safety, efficiency, and compliance of your operations. With various configurations, features, and compatibility considerations to keep in mind, making the right choice ensures your vehicles are properly equipped for both incident recording and ongoing fleet management.
Here’s what you should be looking out for when specifying an MDVR system:
1. Number of Channels – How Many Cameras Do You Need?
One of the first factors to consider is the number of camera channels the MDVR supports. This determines how many cameras can be connected to the unit.
- 4-Channel MDVRs are ideal for smaller vehicles where coverage of the front, rear, and sides is sufficient.
- 8-Channel or 12-Channel MDVRs are more suited to larger vehicles or those requiring comprehensive coverage – for example, internal driver monitoring, blind spot views, and trailer or load surveillance.
Make sure to consider your current needs and potential future expansion. It’s often more cost-effective to choose a higher-channel unit upfront.

2. Monitor Compatibility – Driver Visibility and Reversing Aids
Many MDVRs can be connected to in-cab monitors, giving drivers real-time views from one or more cameras. This is particularly useful for:
- Reversing safety
- Blind spot monitoring
- Load observation in commercial and specialist vehicles
Ensure your chosen MDVR has the right outputs and compatibility with your preferred monitor type (such as AHD monitors or HDMI outputs for higher resolution).

3. Memory Capacity and Storage Type
How much footage your MDVR can store depends on the memory capacity – typically measured in gigabytes (GB) or terabytes (TB). Key factors include:
- Number of cameras recording: More channels = more data.
- Recording resolution and frame rate: Higher quality means larger files.
- Duration of footage storage: How long do you need video retained before it's overwritten?
Most commercial-grade MDVRs use SD cards, HDDs, or SSDs. If you're operating a high-channel system with 24/7 recording, an HDD with at least 1TB is often necessary.
Also consider how often the memory needs to be cleared or changed. Systems with loop recording overwrite the oldest footage automatically, but this can be problematic if footage is needed weeks later.

4. Connected vs Non-Connected
Connected MDVRs:
- Work over 4G/5G networks
- Allow real-time viewing and data upload
- Enable alerts for speeding, harsh braking, door opening, etc.
- Ideal for integration with fleet tracking platforms such as Virtus Fleet Connected
This setup is best for fleets that require remote access to footage, instant alerts, and integration into telematics dashboards for active fleet management.
Non-Connected MDVRs:
- Footage is stored locally
- Retrieval requires physically removing the storage drive
- Typically lower cost but less responsive in the event of incidents
These are suited to smaller fleets or applications where remote access isn’t necessary, but reliable recording is still important.
5. Additional Considerations
- Power Supply: Ensure the MDVR is compatible with your vehicle’s voltage (12V/24V).
- Durability: Look for shock-proof, vibration-resistant units designed for mobile environments.
- Software and Playback: Consider the ease of accessing and reviewing footage.
- Data Protection: Systems with encryption and password protection help ensure GDPR compliance.
Final Thoughts
There’s no one-size-fits-all MDVR. The right solution will depend on your fleet’s size, vehicle types, safety priorities, and whether you're looking for a basic recording setup or a fully connected, intelligent system.
