The Difference Between MDVR and CCTV

What is the difference between a car hard disk recorder, an SD card recorder and an ordinary surveillance recorder

1. Application scenarios

Vehicle-mounted hard disk recorder: Mainly used in vehicles, such as buses, taxis, trucks, etc., to monitor the driving process, with characteristics such as earthquake resistance and high temperature resistance.

SD card recorder: suitable for small surveillance systems, such as homes, small shops, etc., relying on SD card storage, small size and easy installation.

Ordinary surveillance video recorder: used in fixed places, such as shopping malls, office buildings, residential areas, etc., usually connected to multiple cameras, with comprehensive functions.

2. Storage Media
Car DVR: uses a built-in hard disk with large capacity, suitable for long-term recording.

SD card recorder: Relies on SD card, has limited capacity, and needs to be replaced or backed up regularly.

Ordinary surveillance video recorders: Most use hard disks, support large-capacity storage and expansion, and some support network storage.

3. Features

Vehicle-mounted hard disk video recorder: with GPS positioning, G-sensor (collision sensing), loop recording and other functions, adapting to the vehicle environment.

SD card recorder: simple functions, suitable for basic monitoring needs, usually supports motion detection and loop recording.

Ordinary surveillance recorder: rich in functions, supports multi-channel video input, remote monitoring, intelligent analysis, etc., suitable for complex monitoring systems.

4. Durability

Vehicle-mounted hard disk video recorder: shock-resistant, high-temperature resistant, and adaptable to vehicle environment.

SD card recorder: Average durability, suitable for static environments.

Ordinary surveillance video recorders: designed for use in fixed environments, with good durability, but usually do not have the shock resistance of vehicle-mounted equipment.

5. Installation and Maintenance

Vehicle-mounted hard disk video recorder: complex installation, requires professional personnel, and has high maintenance costs.

SD card recorder: easy installation, user-operated, low maintenance cost.
Ordinary surveillance video recorders: installation is complex, requires professionals, and has medium maintenance costs.
