What is an important consideration for positioning sensors in a security system?

When positioning sensors in a security system, it is crucial to take into account the height and angle of the sensor, the type of wall material, as well as the location of windows and doors. Each of these factors plays a significant role in ensuring the overall effectiveness of the security system.

The height and angle of the sensor help to determine its detection range and field of view, which are essential for monitoring movements effectively. An optimal position maximizes the sensor's ability to capture activities within its designated area.

The type of wall material can impact the sensor's performance and range. Different materials may affect the transmission of signals or the sensor's ability to detect motion through walls, thereby influencing where the sensor can be effectively placed.

The location of windows and doors is also vital, as these are common entry points for intruders. Positioning sensors near these areas enhances security by ensuring that any unauthorized entry attempts are detected as quickly as possible.

Taking all these considerations into account ensures the security system can provide the best possible protection for the premises. This holistic approach to sensor placement is why the correct answer encompasses all of these factors.
