What is one disadvantage of relying solely on technology for physical security?

Relying solely on technology for physical security presents a significant disadvantage due to the potential for failures caused by malfunctions or power outages. Technologies such as surveillance cameras, alarms, and access control systems depend on electronic components that can fail unexpectedly. For instance, if a security camera stops working or an alarm's power source fails, it leaves a security gap that can be exploited by intruders. Additionally, during a power outage, many security systems may become entirely inoperative, effectively rendering them useless until power is restored. This reliance on the unbroken function of technological systems highlights a vulnerability that cannot be overlooked, emphasizing the need for a balanced approach that includes both technological and human elements in physical security strategies.
