                                      any Commercial Installation


            Objectives

           At the end of this exercise you shall be able to:
           •  study and demonstrate the CCTV setup in a building.

            Procedure

           The front door, back door, and first-floor windows are the most common entryways for criminals. CCTV camera
           installation service providers should cover main entrances, such as front and back doors, gates, and the paths
           leading up to them.
           They should also monitor first-floor windows, where trouble is most likely. After that, cameras can be placed at
           the corners of your building to capture the entire perimeter. Parking lots and garages are also risky areas, which
           should be monitored day and night.
           Pay attention to the field of view and avoid blind spots when installing business security camera systems. You
           should also pay attention to lighting; placing cameras in well-lit areas ensures a brighter, clearer image. You may
           also consider cameras that use infrared to detect body heat and function similarly to night vision.
           Commercial grade security cameras should be high so people can’t tamper with them — around 9 feet off the
           ground is usually enough. Another thing to consider is whether you want your cameras to be visible to intruders.

           Commercial Installation:
           CCTV cameras serve as a powerful resource when any crime is committed in or around the business premises.
