Which of the following is a critical component of CCTV installation?

Proper camera placement is a critical component of CCTV installation because it directly affects the system's overall effectiveness in monitoring and recording the desired areas. The strategic positioning of cameras ensures that they cover critical zones, such as entry and exit points, high-traffic areas, and blind spots. This placement enables optimal field of view and minimum obstruction, allowing for clearer image capture and better surveillance.

In addition, camera placement is essential for maximizing security and minimizing blind spots. If cameras are not positioned correctly, there may be gaps in surveillance where incidents could occur without detection. Therefore, understanding the layout of the area and the specific security needs is fundamental to an effective CCTV installation.

While decorative brackets may enhance aesthetic appeal, they do not impact the system's functionality. Using wireless technology or employing only digital systems may offer certain advantages, but they are not inherently critical components of installation; instead, they pertain to the broader aspects of technology choice and design. Proper camera placement remains central to achieving a reliable and comprehensive surveillance system.
