Which type of sensor provides high security through high tension and high security techniques?

The type of sensor that provides high security through high tension and high security techniques is the taught wire. Taught wire systems utilize a wire that is stretched tightly between points, creating an effective barrier. When an intruder attempts to cross this barrier, the tension in the wire is disturbed, triggering an alarm. This method is particularly reliable in high-security settings because it can cover large areas and is resistant to various methods of tampering.

In contrast, buried cable systems are typically used for perimeters but might not provide the same level of immediate detection as taught wire. Dual tech motion sensors combine two different technologies (usually passive infrared and microwave), which can reduce false alarms but may not offer the same level of physical security as taught wire. Active sensors detect motion through changes in energy, but they may not be as secure as systems that physically deter or detect intrusion attempts. Thus, the taught wire's approach of creating a physical barrier complemented by alarm activation makes it a superior choice for high-security situations.
