24GHz Radar Camera Blind Spot Detection System with 4-Channel DVR Monitor

The 24GHz radar camera blind spot detection system combines millimeter-wave radar detection, AHD 1080P live video, visual warning zones, audible alerts and four-channel DVR recording in one heavy-duty vehicle safety solution.

The radar camera provides a maximum detection distance of up to 8 meters. The standard three-level warning area covers the nearest 0 to 6 meters and is divided into green, yellow and red zones.

This system is suitable for dump trucks, mining vehicles, construction machinery, municipal vehicles, agricultural equipment and other commercial vehicles with large rear or side blind spots.

Radar Detection, Live Video and DVR Recording in One System

A camera gives the operator a live image, but the operator still needs to watch the monitor continuously.

Radar detects the relative movement and distance of an object, but radar alone cannot show the operator what the target is.

This system combines both technologies with video recording:

• 24GHz millimeter-wave radar detection
• Maximum detection distance up to 8m
• AHD 1080P live video
• Three color-coded warning zones
• Two-level audible warning
• Four-channel mixed video input
• Four-channel DVR recording
• Independent recording and playback for each channel
• SD card storage up to 256GB

The operator can receive an active warning, confirm the situation visually and keep video records for later review.

Maximum Detection Distance and Warning Zones

The radar camera can detect targets at distances of up to 8 meters under suitable installation and operating conditions.

The three standard visual warning zones cover the nearest 0 to 6 meters.

Green Warning Zone: 6.0–4.5m

The green zone indicates that an object has entered the outer active warning area.

The operator should check the monitor and remain aware of the object’s movement.

Yellow Warning Zone: 4.5–2.0m

The yellow zone indicates that the object is moving closer to the vehicle.

The operator should reduce speed and prepare to stop or adjust the vehicle movement when necessary.

Red Warning Zone: 2.0–0m

The red zone indicates that the object is very close to the vehicle.

The operator should immediately check the live image and stop or change direction when required.

Early Detection Area: 8.0–6.0m

The area between 8 and 6 meters provides earlier target detection before the object enters the standard three-level warning zones.

Actual detection performance depends on target size, movement, mounting height, radar angle, vehicle structure and operating environment.

Relative Movement Detection

The radar alarm function uses relative object movement detection.

It detects the relative movement of workers, vehicles or obstacles inside the monitored area and triggers visual and audible warnings according to the target distance.

This function is useful when heavy vehicles are reversing, turning or maneuvering at low speed around people and equipment.

AHD 1080P Radar Camera with Seven IR LEDs

The radar camera integrates a 1/2.9-inch CMOS image sensor, AHD 1080P video output and seven infrared LEDs.

Camera features include:

• 1920 × 1080 effective pixels
• PAL / NTSC support
• 25 / 30 fps frame rate
• 0.01 Lux minimum illumination
• 0 Lux with infrared illumination
• 81dB dynamic range
• Day and night monitoring
• IP69K waterproof protection
• Shock-resistant structure

The infrared LEDs support low-light and nighttime monitoring, while the live image helps the operator identify the detected target.

Adjustable Radar and Camera Angles

The radar module and camera viewing direction can be adjusted separately.

This allows installers to match the radar coverage and camera image to the actual blind spot of the vehicle.

Adjustable elements include:

• Radar sensing angle
• Horizontal radar module angle
• Camera horizontal viewing angle
• Camera mounting bracket position

After installation, both the live image and radar detection area should be tested on the actual vehicle.

7-Inch Four-Channel DVR Monitor

The 7-inch vehicle monitor supports four-channel mixed video input, multi-view display and DVR recording.

It can connect the radar camera together with other compatible vehicle cameras, including:

• Rear-view camera
• Left-side camera
• Right-side camera
• Front-view camera
• In-cab camera

The monitor supports 18 split-screen display layouts and can record all four input channels.

Each channel is saved as a separate video file for independent playback.

DVR Recording Functions

The monitor supports:

• SD card storage up to 256GB
• Four-channel simultaneous recording
• Separate video files for each channel
• AVI recording format
• Automatic loop recording
• Automatic overwrite of unlocked files
• Recording duration options of 1, 3, 5 or 10 minutes
• Video preview and playback
• System time setting
• Recording timestamp display

The SD card should be formatted through the monitor menu before first use.

Independent Channel Settings

Each video channel can be configured independently.

Available settings include:

• Reversing guideline on or off
• Reverse return delay from 0 to 15 seconds
• Mirror image on or off
• Vertical image flip
• Brightness adjustment
• Contrast adjustment
• Chromaticity adjustment
• Individual channel image adjustment

This makes the system easier to integrate with cameras installed in different directions.

Suitable Vehicles

This radar camera system is suitable for:

• Mining dump trucks
• Rigid dump trucks
• Articulated dump trucks
• Excavators
• Wheel loaders
• Concrete mixers
• Garbage trucks
• Municipal vehicles
• Agricultural machinery
• Heavy commercial trucks
• Construction vehicles
• Special-purpose vehicles

Typical Applications

Reversing Detection

The radar camera can monitor workers, vehicles and obstacles behind a heavy vehicle during reversing.

When a target enters the warning area, the monitor displays the corresponding color zone and the system provides an audible alert.

Side Blind Spot Monitoring

The radar camera can be installed on the side of a long vehicle to detect moving targets beside the vehicle body.

This is useful during turning, lane changing and low-speed movement.

Mining and Quarry Operations

Mining vehicles frequently operate around workers, service vehicles, stockpiles and loading equipment.

The combined radar and camera system helps the operator monitor blind spots while retaining video records for later review.

Construction Site Maneuvering

Construction vehicles often work in restricted areas around workers and other equipment.

The system can improve awareness during reversing, turning and low-speed maneuvering.

Why Combine Radar, Video and Recording?

Radar, cameras and DVR recording provide different functions.

Radar detects a target and estimates its distance.

The camera gives the operator a live visual reference.

The DVR monitor records the event for later review.

Together, the system provides:

• Active target detection
• Real-time visual confirmation
• Distance-based warning
• Audible operator alerts
• Multi-camera monitoring
• Video recording and playback

This is especially useful for heavy vehicles where a camera-only system may not provide enough active warning.

Important Safety Notice

This system is a driver-assistance product.

It helps improve operator awareness but does not replace:

• Mirrors
• Direct observation
• Trained spotters
• Site safety procedures
• Safe driving practices
• Operator responsibility

Radar and camera performance may be affected by installation angle, vehicle structure, target type, weather, vibration, mud, dust and system settings.
