Which type of wiring is typically used for security systems in a residence?

Low-voltage wire is commonly used for security systems in residential settings due to its specific characteristics that meet the needs of these installations. Security systems, which often include alarms, cameras, and sensors, typically operate at lower voltages for safety and efficiency. Low-voltage wires are designed to carry power and signals effectively over distances without the risk of overheating or posing hazards associated with higher voltage wiring.

These wires come in various forms and gauges, providing flexibility in installation based on the specific requirements of the security system. Utilizing low-voltage wire helps ensure that the system operates reliably while minimizing the risk of electrical interference, which can be crucial for the performance of sensitive security equipment.

The other types of wiring mentioned, while useful in different applications, do not serve as the standard for residential security systems. For instance, TW wire is typically used for lighting and general electrical installations; shielded cable is generally utilized for data transmission or environments where electromagnetic interference is a concern; and thermal wire is not commonly associated with security systems. Each of these alternatives has its specific use case but does not align with the typical requirements and standards for wiring security systems in residences.
