Understanding car alarm systems

Two men discuss how remote entry car alarm system work

Modern car owners can install different car alarm systems ranging from door sensors to sophisticated proximity sensors. But how do they work?

Car alarms have sensors, and when they’re on, they receive a response- through touch, proximity, or an unusual activity near the vehicle. This response will activate the alarm to make a sound or continuously flashlights.

The car security alarm system has a computer, a receiver, a loudspeaker, and other sensors. For instance, the ultrasonic sensors detect unusual movement in the car’s interior.

Types of car alarm systems

A car alarm system is either passive or active. A passive car alarm system automatically activates once the ignition is turned off and all the doors are closed, reducing the risk of forgetting to set it. On the other hand, an active alarm system requires the driver to activate the alarm manually. Understanding this difference can help retailers recommend the right choice for their target market.

1. Passive car alarm systems

It is passive because it automatically activates once the ignition is turned off and all the doors are closed. The car user doesn’t have to engage the system manually, thus reducing the risk of forgetting to set it.

Passive car alarm is the most common vehicle protection system. Besides, its convenient automatic activation ensures battery safety and offers constant protection.

2. Active car alarm systems

Unlike passive car alarm systems, active alarm systems require the driver to activate the alarm manually. The system remains inactive until the user engages it.

However, you may wonder if car alarm systems are worth stocking as a retailer. Let’s find out in the next section.

Factors customers consider when choosing a car alarm system

Level of protection

The truth is- not all car alarm systems offer the same level of protection. Budget-conscious customers will likely prefer the audible car alarm system with only basic features like door sensors and sirens.

On the other hand, some car owners who want advanced car protection will invest in GPS alarm systems and two-way paging alarms with advanced features like GPS tracking, remote start, motion sensors, and ignition cut-off technology.

Compatibility with vehicle

Car alarms are not one size fits all. Different customers choose different alarm systems that are compatible with their vehicle model.

Alarms for trucks are not the same as those for SUVs or luxury vehicles. As a retailer, it is essential you stock different alarm systems that will work seamlessly with your customers’ car’s existing electronics and features. You should also stock alarms that suit old vehicles or cars without modern security.

Smart features

Technology permeates every human life because of its convenience and security. Car security systems customers constantly seek products with smart features to monitor their car’s security from anywhere. These smart features include smartphone apps, GPS tracking, and motion sensors that give vehicle owners control. Tech-savvy users find smartphone apps useful in arming/disarming, monitoring, and receiving notifications remotely.

Remote start

Car owners value convenience, and the remote start system fulfills this demand. Besides providing a keyless entry, car owners can start their vehicles and adjust the temperature inside before entering. This feature is useful in extreme weather conditions, allowing car owners to warm up or cool down their cars before entering.

While some manufacturers install remote starters, other vehicles don’t have this security feature. Car owners without these protection mechanisms may want to invest in a remote start system to enjoy the convenience of keyless entry, the comfort of controlled temperature, and the luxury of peace of mind.

Budget

Like any product, the customer’s budget determines what car alarm system they select. While every car owner may want top-of-the-line security systems, others may be constrained by a budget.

Fortunately, these alarms range from a more affordable entry-level system to high-end systems at a premium price. As a retailer, know your customer base and determine what car security alarm system you’ll stock more.

Mild-range systems that balance affordability and advanced features like remote start are often popular with most customers. So, stocking across various price ranges can attract a broader audience to your store.
