Question 1

What does the term 'lux rating' on a surveillance camera specification indicate?

Accepted Answer

The minimum light level required for the camera to produce a usable image

Answer

Lux rating specifies the minimum illumination level at which a camera can produce a usable image; lower lux values indicate better low-light performance.

Question 2

During a mobile surveillance operation, the 'eye' refers to:

Accepted Answer

The team member with direct visual on the subject at any given moment

Answer

The 'eye' is surveillance terminology for the operator who currently has direct visual contact with the subject and is responsible for directing other team members.

Question 3

Which video compression standard offers the best balance of image quality and bandwidth efficiency for modern IP surveillance systems?

Accepted Answer

H.265/HEVC

Answer

H.265/HEVC achieves approximately 50% better compression efficiency than H.264 at equivalent quality, significantly reducing bandwidth and storage requirements for surveillance systems.

Question 4

An operator notices a camera's image has become blurry only at night while daytime images remain sharp. The most likely cause is:

Accepted Answer

IR focal shift due to the camera lens not being IR-corrected

Answer

IR focal shift occurs when infrared light focuses at a slightly different plane than visible light, causing blur in cameras with lenses not optically corrected for IR wavelengths.

Question 5

What is the legal doctrine of 'reasonable expectation of privacy' primarily used to determine in surveillance operations?

Accepted Answer

Whether conducting surveillance in a particular location requires legal authorization

Answer

The reasonable expectation of privacy doctrine, established in Katz v. United States, determines where government surveillance requires legal authorization versus public observation.
