Question 1

When designing camera placement to eliminate blind spots in a parking lot, which camera type provides the widest area coverage with a single unit?

Accepted Answer

360-degree fisheye camera mounted at the center of the lot

Answer

A 360-degree fisheye camera mounted at the center of a parking lot can capture the entire surrounding area in a single wide-angle view, minimizing blind spots.

Question 2

During installation of a network video recorder (NVR), what is the correct procedure when adding cameras to ensure the system clock is accurate?

Accepted Answer

Synchronize all cameras and the NVR to an NTP server to ensure consistent timestamps

Answer

Synchronizing all devices to an NTP server ensures consistent, accurate timestamps across all cameras and the NVR, which is critical for forensic video review.

Question 3

A security director requests cameras with license plate capture capability at a parking garage entrance. What lens specification is most critical for this application?

Accepted Answer

Long focal length lens (12mm or greater) to narrow the field of view and capture plate detail

Answer

License plate capture requires a narrow field of view achieved with a longer focal length lens to capture enough pixel density on the plate for character recognition.

Question 4

What is the recommended minimum lux rating for an IP camera to be installed in an area with only emergency lighting (approximately 0.5 lux)?

Accepted Answer

A camera rated for 0.1 lux or lower minimum illumination

Answer

To capture usable images in 0.5 lux conditions, the camera must have a minimum illumination rating below the ambient light level, such as 0.1 lux.

Question 5

When pulling cable through conduit during a surveillance installation, what is the maximum fill ratio recommended to prevent cable damage and overheating?

Accepted Answer

25% of the conduit's cross-sectional area for one cable, 40% for multiple cables

Answer

NEC guidelines recommend no more than 25% fill for a single cable and 40% fill for multiple cables to allow for heat dissipation and ease of future cable pulls.
