With the rapid advancement of technology, the market is flooded with various video surveillance and intelligent anti-theft alarm systems. These innovations offer great potential for enhancing security and detecting threats swiftly. However, despite the variety of sensors available—such as those based on human pyroelectricity, microwaves, and door sensors—the alarm trigger signals often rely on subtle physical changes, which can lead to blind spots or dead zones. External environmental factors and the limitations of these detectors' physical properties can result in false positives or false negatives, posing risks to users.
Home invasions and robberies are a persistent threat globally, regardless of time or place. These incidents not only endanger personal safety and property but also represent a significant challenge for societal security. While institutions and organizations may employ guards, install surveillance cameras, and set up alarm systems, these measures often fall short of complete protection. Even with public awareness of preventive measures like traditional security nets and anti-theft windows, these solutions often introduce new problems such as obstructing fire escapes, detracting from urban aesthetics, and even aiding criminals in their efforts.
To capture the market quickly, alarm manufacturers often design bulky, wall-mounted detectors for ease of installation. Unfortunately, this approach inadvertently provides opportunities for criminals to tamper with or disable these devices, rendering them ineffective. Moreover, as income inequality grows, driven by psychological imbalances among certain groups and exacerbated by an increasing transient population, theft and robbery become more frequent. Despite the rarity of such incidents, their impact on victims is severe. Therefore, it is crucial to focus on installing and utilizing surveillance and telephone alarm systems effectively.
Currently, wireless smart alarms available in the market are praised for their high performance, broad monitoring range, and intelligence. Yet, their high cost and susceptibility to interference remain concerns. Many of these alarms operate on fixed frequencies and modes, making them vulnerable to sophisticated thieves. Issues surrounding emergency phone alarms include:
1. Aesthetic concerns arise when beautifully designed doors and windows are paired with outdated anti-theft devices, disrupting the overall decor. Additionally, mounted detectors might be prone to tampering or counter-alarm actions.
2. High-frequency electronic products, when placed in living rooms or bedrooms, can suffer from interference from large appliances, diminishing their effectiveness.
3. Human pyroelectric infrared or microwave sensors, while intelligent and capable of setting multiple defense zones and alarm calls, can misfire due to heat sources, bright lights, or hot air currents. Their sensitivity to temperature variations and difficulty detecting movement behind glass can lead to missed reports or false alarms.
4. Door sensors, though reliable, are bulky and surface-mounted, making them susceptible to damage or countermeasures. Acquaintance-based crimes pose additional risks.
5. Dual-sensor detectors combining human pyroelectric infrared and microwave detection enhance accuracy but are hindered by obstacles like walls and furniture. Experienced criminals could exploit this limitation.
6. Most detectors are mounted and offer opportunities for vandalism or counter-alarm setups. Innovations focusing on concealment and reducing blind spots are essential.
7. Smart alarms can be complex to operate, particularly for older users or those unfamiliar with technology. Simplifying setup, programming, and response procedures is vital.
Addressing these challenges requires innovation in design, improved intelligence, and better integration with existing systems. By focusing on these areas, we can create more effective and user-friendly security solutions.
