With increasing road accidents globally every year, vehicle safety has become a major area of concern. One of the most effective and affordable ways to improve safety on roads is through the use of vehicle cameras. From documenting evidence in case of an accident to monitoring driver behavior, cameras installed in vehicles can play a key role. In this article, we discuss the various types of cameras used in vehicles, their benefits and challenges.
Dashcams
One of the most common types of in-vehicle cameras are dashcams. Usually
mounted on the windshield facing forward, dashcams start recording as soon as
the vehicle ignition is turned on. They continuously record video footage from
the driver's perspective. Dashcams serve multiple purposes like documenting
evidence in case of an accident, traffic violation or road rage incident. The
footage acts as irrefutable proof and helps determine liability. It protects
drivers from false insurance claims and bogus traffic violation notices.
Dashcams also discourage rash driving and road rage behavior knowing one's
actions are being recorded. However, privacy continues to be a concern with
wide adoption of dashcams. Stricter regulations are needed around storage and
use of footage.
Interior Cameras
Going beyond dashcams, some vehicles are now being equipped with interior
cameras mainly aimed at monitoring driver behavior. For commercial fleets,
interior cameras help track driver hours, monitor driving speeds, lane changing
habits and hard braking events. This data is then analyzed to identify unsafe
driving behaviors and coach drivers. For personal vehicles, interior cameras
can double up as cabin cameras providing rear seat view for parents when
children are in the vehicle. However, concerns around privacy and surveillance
persist with interior cameras. Regulations need to define extent of monitoring
and use of recorded footage. Consent also plays a key role and cameras should
have capability for drivers and passengers to disable recording.
Exterior Cameras
In addition to views from inside the vehicle, exterior cameras are being
introduced to provide broader context around the vehicle. For commercial
vehicles like trucks, exterior cameras provide rear, side and bird-eye views
helping maneuver in tight spaces safely. Advanced systems stitch together feeds
from multiple exterior cameras to generate 360 degree surround view. Such
camera systems eliminate blind spots improving safety for pedestrians and
cyclists around large commercial vehicles. For personal vehicles, rear view
cameras are now mandated on new vehicles while four corner cameras are being
introduced on top end luxury cars providing a surround view. Newer systems even
overlay parking guidance graphics on live camera feeds. However, for exterior
cameras on personal vehicles, how footage will be stored and accessed requires
proper guidelines.
Advanced Driver Assistance Systems
(ADAS)
Vehicle
Cameras are also crucial components of emerging ADAS technologies aimed
at enhancing safety. Forward facing cameras powering ADAS technologies like
autonomous emergency braking, adaptive cruise control with stop-go, lane keep
assist etc. provide perception to vehicles about the driving environment. Such
integrated driver assistance systems actively monitor the road ahead, sense
imminent collisions and intervene autonomously to avoid accidents if the driver
fails to react in time. Over time, automakers are increasing the number of
cameras on vehicles to support more sophisticated ADAS and autonomous driving
functions. However, regulations need to ensure proper testing, validation and
cybersecurity of such camera-based ADAS systems before allowing autonomous
vehicle piloting on public roads.
Data Privacy and Security Concerns
With more camera systems collecting terabytes of video data from vehicles
day, the question of how this data is stored, accessed and protected becomes
important. There is a need for global standards around data privacy, ownership,
access rights, storage duration and consent for third party use. Strict laws
need to govern how automakers and technology firms leverage vast volumes of
driving scene data collected from networked vehicle cameras over the air.
Equally important is to put robust cybersecurity safeguards in place to protect
sensitive driver, passenger and location data streamed from vehicles. Any
security breach could enable stalking or other misuse of personal information.
In summary, cameras integrated into vehicles are revolutionizing safety, driver
monitoring as well as opening up possibilities of autonomous driving. While
they have clear benefits, especially in reducing road accidents, key challenges
around data privacy, security, driver surveillance and regulation of new
technologies like integrated ADAS need to be addressed proactively. Global
standards, clear guidelines on consent, data access rights and purging
timelines can help realize full promise of cameras for safety, while assuring
users on privacy protection. With responsible deployment, vehicle cameras are
set to transform mobility experience and make roads safer for all.
