A car security system is a comprehensive network of electronic and mechanical components which are designed to protect a vehicle from unauthorized access, theft, and vandalism. These systems typically include alarm sirens, immobilizers, keyless entry, central locking, motion detectors, and GPS tracking technologies. Car security systems function by detecting suspicious activities such as forced entry or vehicle movement and triggering alerts to deter intruders or notify the vehicle owner. As vehicle theft methods are evolving, modern security systems are being integrated with smart features such as biometric access, smartphone controls, and real-time tracking, making them essential for personal vehicle protection and insurance compliance.

Automotive window power sunshade is categorized under automotive accessories. The technological advancements in automotive window power systems have resulted in window power sunshades. An automotive window power sunshade operates electronically to regulate the amount of sunlight entering the vehicles cabin. Power sunshades are found on the rear windows, side windows, and sunroofs of vehicles

Automotive sealants are specialized materials used to fill gaps, joints, and seams in vehicles to prevent the entry of water, dust, air, and other contaminants. They enhance vehicle durability by providing protection against corrosion, vibration, and environmental damage. These sealants are critical in various automotive applications, including body sealing, window glazing, chassis assembly, and battery protection in electric vehicles.

Automotive floor carpets are used to cover the floor of the passenger compartment in light commercial vehicles, passenger cars, and heavy commercial vehicles. Floor carpets prevent transferring heat, noise, and vibration from beneath the vehicles floor to the passenger cabin, which is manufactured of non-woven and tufted materials.

Automotive refurbished turbochargers are remanufactured turbochargers that are manufactured to the standard of OE turbochargers. Wearable components are replaced with new components during the refurbishing process, and all components of the automotive refurbished turbocharger are inspected against OE specifications for correct dimensional tolerances.

Automotive camera-based side mirrors, also known as digital side mirrors or virtual mirrors, replace traditional side mirrors with cameras and displays. These systems use high-resolution cameras mounted on the exterior of the vehicle to capture real-time video footage of the surrounding area. The video feed is then displayed on screens located inside the car, typically on the A-pillars or dashboard. This technology enhances visibility by reducing blind spots and providing a wider field of view, especially in low-light conditions or adverse weather

A radiator fan is a device that sucks the atmospheric air through radiator panels and expels it into the atmosphere to cool the engine coolant after discharge from the engine. The radiator fan maintains an acceptable operating temperature by transferring heat from the engine to the atmospheric air. Hence, the radiator fan prevents the wear and tear of engine components. It also ensures that the automotive engine operates at an optimal temperature for better fuel efficiency.

Automotive refinish coatings are specialized paints and protective layers applied to vehicles after their original manufacturing, typically during repairs, repainting, or customization. These coatings restore the vehicles appearance, protect the surface from corrosion and environmental damage, and ensure color matching and aesthetic consistency with the original factory finish.

Automotive fasteners are components used in automobiles and vehicle assembly, which include bolts, screws, nuts, washers, rivets, concrete anchors, inserts, threaded rods, and retaining rings that are used exclusively for automotive manufacturing.

Automotive wrap films offer car styling and personalization through full or partial wrapping. Vehicles with such wraps are used as moving billboards for business advertisements.
