Capacitance proximity sensors detect changes in electrical capacitance, which can be influenced by environmental conditions. Changes in relative humidity can affect the dielectric properties of the air or materials nearby, potentially causing false alarms or degraded performance.
B (Temperature) and C (Air movement) typically affect other sensor types (e.g., infrared or ultrasonic).
D (End-of-line resistance) applies to alarm circuit supervision, not proximity sensing.

Crime Prevention Through Environmental Design (CPTED) is a proactive design philosophy that uses environmental elements to reduce crime opportunities. One of its core principles is natural surveillance, which involves designing spaces so that legitimate users can easily observe their surroundings. This increases perceived risk for offenders and discourages criminal activity.
A (Balanced systems), B (Protection in depth), and D (Layered defense) are principles used in security system design but not specific to CPTED.

Comprehensive Detailed Explanation:
Pandemics primarily impact human health and workforce availability rather than directly damaging physical infrastructure. The effects on infrastructure are typically secondary, such as reduced staffing at utilities or service providers, rather than structural destruction (as in natural disasters).
Infrastructure remains physically intact, but operations may be disrupted due to workforce shortages.

The accounting or finance department typically has oversight of all monetary assets, including cash flow, budgets, payroll, and financial reporting. This central role makes it particularly vulnerable to internal fraud, embezzlement, and cybercrime. Security measures here often include both physical controls and procedural checks (e.g., audits, access controls, separation of duties).

The three keys to a successful contract or partnership in the context of security management are:
Accessibility: Open communication and availability between parties.
Meetings: Regular reviews and check-ins to ensure alignment.
Resource Management: Efficient allocation and use of both personnel and technical resources.
These three elements contribute to maintaining accountability, service quality, and responsiveness between the security provider and client.
