✍️ Sample CCTV Questions & Answers
1. When mounting a dome camera on a suspended ceiling, which hardware is most appropriate?
A pendant mount with ceiling adapter provides the structural support and proper angle adjustment needed for suspended ceiling installations.
2. Which detector is most commonly integrated with CCTV to trigger motion-based recording?
Passive Infrared (PIR) detectors sense heat signatures from moving people and are widely used to trigger CCTV recording when motion is detected in a protected zone.
3. Which camera form factor is most suitable for discreet indoor surveillance where the camera should be nearly invisible?
Pinhole cameras use an extremely small lens opening that can be concealed behind a tiny hole in a wall, ceiling tile, or everyday object, making them nearly undetectable.
4. In a modern IP surveillance system, what is the primary function of a PoE switch?
A Power over Ethernet (PoE) switch is a network switch that has Power over Ethernet injection built-in. It is used to connect and power PoE-enabled devices, such as IP cameras, using a single Ethernet cable for both data transmission and electrical power.
5. Which cable type is preferred for PTZ camera control signals over long distances?
RS-485 twisted pair cable is the standard for PTZ control signals because it supports long-distance, noise-resistant differential signaling.
6. What is 'covert' CCTV, and when might it be used?
Covert CCTV involves concealed cameras used for specific investigations where the presence of visible cameras would prevent the activity being investigated.
