Electronic Security Technician Level 1 Practice Exam

In a CCTV system, there are various types of cameras designed to meet different surveillance needs and environments, and the choice of camera can significantly impact the effectiveness of a security system.

Dome cameras are favored for their discreet appearance and can often be mounted on ceilings. Their design helps to prevent tampering and allows for a 360-degree view of the area. Bullet cameras, on the other hand, are typically mounted on walls and are recognizable by their cylindrical shape, making them suitable for outdoor usage due to their weather-resistant features. PTZ (Pan-Tilt-Zoom) cameras are versatile and allow operators to move the camera view remotely, which is ideal for monitoring large areas and focusing on specific events. Thermal cameras excel in detecting heat signatures, making them particularly useful in low-light or no-light conditions, such as at night.

The other options include types of cameras that either do not specifically pertain to standard CCTV applications or focus on characteristics rather than the types typically used in surveillance systems. For instance, while digital and analog cameras are important distinctions, they may not fully capture the common formats within a standard CCTV system like dome or bullet cameras do. Similarly, terms like handheld or security camcorders involve a different context than traditional stationary CCTV setups.
