Car Alarm Accessories & Security Upgrades in Cleveland, Ohio

Add another layer of detection to your vehicle's security system. At Access 1 Alarm & Audio, we offer professionally installed car alarm accessories and security sensor upgrades for drivers throughout Cleveland and Northeast Ohio. Compatible accessories can help your alarm detect impacts, breaking glass, vehicle lifting and movement near or inside your vehicle.

Choose upgrades around your vehicle, existing alarm and security priorities. From additional sensors and sirens to backup power and automatic window control, available features depend on the equipment installed and its compatibility with your car, truck or SUV.

Accessory Options for Compatible Alarm Systems

• Tilt sensors: Detect changes in vehicle angle that may occur during lifting, wheel theft or towing attempts.
• Glass break sensors: Detect the sound of breaking glass to supplement door and impact monitoring.
• Perimeter and proximity sensors: Detect movement within an adjustable sensing zone, with warning or alarm responses determined by the system and configuration.
• Backup batteries and backup sirens: Provide reserve power for compatible alarm equipment or a separately powered siren if vehicle power is disconnected. Operation and runtime vary by equipment.
• Shock sensors: Detect impacts and vibrations, with sensitivity adjusted to suit the vehicle and installation.
• Automatic window roll-up modules: Add window-closing control through a compatible security system, subject to vehicle and module requirements.

Check compatibility before purchasing. Car alarm accessories are not universally interchangeable, even within the same brand. Have your alarm's brand and model number available so we can help identify supported upgrades, required connections and any additional equipment needed. Many aftermarket sensors require a compatible aftermarket alarm or a separate interface to work with factory security.
