Affver A4 4K + 2.5K Dash Cam Front and Rear – Upgraded 2026 Model

4K Ultra HD Front Camera with 160° Wide-Angle Coverage

The Affver A4 front camera records in 4K Ultra HD, providing greater image detail than conventional 1080P dash cameras.

Its 160-degree viewing angle helps capture a broad section of the road ahead, including surrounding traffic and portions of adjacent lanes.

High-resolution front recording can be useful when reviewing:

• Traffic collisions and unexpected roadway incidents.
• Vehicles merging into your lane.
• Road signs and traffic signals.
• Sudden braking events.
• Highway driving conditions.
• Scenic drives and road trips.

The additional resolution can help preserve useful visual information, although actual license plate readability depends on lighting, distance, vehicle movement, and recording settings.

Upgraded 2.5K Rear Camera with 155° Viewing Angle

One of the biggest selling points of the upgraded Affver A4 is its higher-resolution rear camera.

Instead of the 1080P rear recording found on the previous model, the updated A4 captures footage at an advertised 2.5K resolution.

The rear camera also features a 155-degree viewing angle, providing broad coverage of traffic approaching from behind.

This can be especially useful when documenting rear-end collisions, vehicles following too closely, and other unexpected events involving traffic behind your vehicle.

For drivers who prioritize rear recording quality, the upgraded camera is an important improvement over the earlier Affver A4.

F1.5 Aperture and Six-Layer Lens for Enhanced Night Vision

Driving after dark creates difficult recording conditions for any dash camera.

Headlights, poorly lit roads, reflective signs, and changing exposure can make important details harder to capture.

The Affver A4 uses an advertised F1.5 aperture and six-layer optical lens construction designed to support low-light recording.

Affver also claims the lens configuration increases light intake by 60%, although the supplied information does not identify the comparison baseline.

A wider aperture can help gather more light, while the six-layer lens and image processing work together to preserve useful detail.

These features are especially relevant for drivers who frequently commute early in the morning or travel after sunset.

WDR Technology for Balanced Day and Night Footage

Wide Dynamic Range technology helps balance bright and dark areas within the same recorded scene.

This can improve visibility when driving through environments with strong lighting contrasts.

Examples include:

• Nighttime roads with bright approaching headlights.
• Parking garages.
• Tunnel entrances and exits.
• Bright sunlight combined with deep shadows.
• Roads with inconsistent street lighting.

The Affver A4 automatically adjusts exposure to help maintain usable footage in changing lighting conditions.

Actual recording performance depends on ambient light, vehicle speed, and camera settings.

5GHz WiFi 6 for Faster Smartphone Video Downloads

The upgraded Affver A4 features 5GHz WiFi 6 connectivity for wireless access to supported camera functions.

Using the compatible Affver smartphone application, drivers can review and download recorded footage.

The manufacturer advertises download speeds of up to 10MB/s, a 25% increase over the previous A4’s stated 8MB/s maximum.

Faster transfers are especially useful when handling large 4K video files.

Wireless connectivity also makes it easier to save important footage without removing the memory card.

Important: WiFi 6 provides local wireless communication between the dash camera and a compatible smartphone. It does not mean the camera includes 5G cellular service or independent internet access.

Built-In GPS for Speed, Location and Route Recording

The Affver A4 includes built-in GPS designed to record driving information alongside video footage.

Supported information includes:

• Vehicle speed.
• Driving route.
• Geographic coordinates.
• Location information.

According to the supplied specifications, recorded journeys can be reviewed through the compatible mobile application or Affver’s GPS playback software for Windows and Mac.

GPS data can provide additional context when reviewing a traffic incident or documenting a particular trip.

For automotive enthusiasts, GPS-tagged footage can also help organize recordings from scenic drives and road trips.

GPS accuracy depends on satellite reception and environmental conditions.

Large 3.59-Inch IPS Display

The Affver A4 features a 3.59-inch IPS display designed for convenient video review and camera operation.

The larger screen provides room to navigate settings, check camera positioning, and access supported recordings.

IPS display technology is designed to provide consistent visibility from different viewing angles.

During installation, the display can help confirm that the front camera is properly positioned and that the rear camera captures the intended area.

Low-Profile Design for a Cleaner Interior

The Affver A4 uses a compact, low-profile design intended to minimize visual obstruction.

This makes it appealing to drivers who prefer a discreet dash camera installation rather than a large device dominating the windshield.

A properly positioned camera can provide useful roadway coverage while keeping the driver’s forward view clear.

For modified vehicles, sports sedans, and daily drivers, a clean installation can also help preserve the appearance of the interior.

Free 64GB Memory Card Included

The Affver A4 includes a 64GB memory card, allowing drivers to begin recording without purchasing additional storage immediately.

This is convenient for a dual-channel system that records 4K front footage and 2.5K rear footage simultaneously.

Recording retention depends on bitrate, video settings, and the amount of protected footage stored on the card.

Follow Affver’s formatting recommendations and periodically verify that recordings are being saved correctly.

The maximum supported memory card capacity is not specified in the supplied information.

Automatic Loop Recording

The Affver A4 supports automatic loop recording.

When the memory card approaches capacity, the camera overwrites eligible older recordings to make room for new footage.

This helps maintain everyday recording without requiring drivers to manually delete files after each trip.

For commuters and long-distance drivers, loop recording reduces routine storage maintenance.

Important footage should still be transferred to separate storage promptly after an incident.

Three-Axis G-Sensor with Emergency Video Protection

The Affver A4 includes a built-in three-axis gravity sensor designed to detect sudden impacts or collisions.

When a qualifying event occurs, the camera automatically locks the associated recording to help prevent it from being overwritten during normal loop recording.

This can help preserve footage involving:

• Rear-end collisions.
• Sudden roadway impacts.
• Unexpected traffic incidents.
• Other events that trigger the collision sensor.

Emergency video locking provides an additional safeguard when drivers cannot manually save footage immediately.

Protected recordings should still be backed up when practical.

USB-Equipped Car Charger Keeps Your Charging Port Useful

A practical feature of the Affver A4 package is its included car charger with an additional USB port.

Many dash cameras occupy a vehicle’s 12V accessory socket, leaving drivers without a convenient place to charge another device.

The Affver charger includes a USB port that can be used to power or charge a compatible phone or other accessory while the dash camera operates.

This is particularly useful for drivers who rely on smartphone navigation, rideshare applications, or hands-free communication during longer journeys.

Charging performance depends on the charger’s output specifications and the connected device.

Straightforward Front and Rear Camera Installation

The Affver A4 is designed for straightforward installation using the included accessories and installation tools.

Position the main camera on the windshield where it has an unobstructed roadway view without interfering with the driver’s visibility.

Install the rear camera where it can capture approaching traffic.

Route wiring carefully through appropriate interior trim areas and keep cables away from moving components and airbag deployment zones.

For DIY installers, understanding basic automotive wiring principles can help prevent unnecessary electrical problems.

Before installing additional automotive accessories, review the Car Wiring Guide – Essential Tools at My Pro Street Online for useful information about wiring tools and installation preparation.

The A4’s low-profile design helps support a clean, discreet installation when mounted correctly.

Ideal for Daily Drivers, Families and Automotive Enthusiasts

The upgraded Affver A4 is suitable for drivers who want high-resolution front and rear recording without installing a three-camera system.

Daily commuters benefit from broad front and rear coverage during heavy traffic.

Families gain additional recording perspectives for everyday travel and long-distance trips.

New drivers can use recorded footage to review unexpected situations and develop greater awareness of driving conditions.

Rideshare drivers benefit from front and rear recording, although this model does not include a dedicated interior camera.

Automotive enthusiasts can use the 4K front camera, upgraded 2.5K rear camera, and GPS information to document road trips and memorable drives.

For drivers interested in maintaining reliable automotive electrical systems, My Pro Street Online also publishes technical maintenance and diagnostic resources, including How to Test Alternator Output With a Multimeter.

24-Month Manufacturer Warranty

According to the supplied product information, Affver provides a 24-month warranty for the A4 dash camera.

The manufacturer also advertises technical support and after-sales assistance for installation and product questions.

Actual warranty eligibility and coverage depend on the manufacturer’s current terms.
