Question

Ricardo wants to install two security cameras at point A so the parking lot from side AE to side AB of the building can be monitored. Can he use two​ cameras, both with a field of view of 110°​, installed at point​ A? Explain. If​ not, what is the minimum field of view that each camera should​ have?

Answer 1

Explanation:

The two cameras will have total view of:

• 110° + 110° = 220°

The angle to be viewed is:

• 270° - 15° = 255°

This is not sufficient to cover the needed area as 220° < 255°

The cameras should have a minimum view of:

• 255°/2 = 127.5°
