Surveillance Systems Installation Flashcards

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

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

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.

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

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

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

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

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

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.

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)?

Answer: A camera rated for 0.1 lux or lower minimum illumination

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.

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

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

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.

A technician is tasked with installing a PTZ camera on a pole mount in a parking lot. What factor must be considered first before beginning the installation?

Answer: Calculating the pole's load-bearing capacity to support camera weight and wind load

Pole-mounted cameras, especially PTZs, exert significant wind load forces, so the pole must be rated to support the combined weight and dynamic wind forces to prevent failure.

When installing cameras in a facility that processes cardholder data, which compliance framework governs physical security requirements including surveillance system placement?

Answer: PCI DSS (Payment Card Industry Data Security Standard)

PCI DSS includes physical security requirements, including monitoring of card data environments with surveillance cameras to protect cardholder data.
