CSM Security Technology & Surveillance Systems Flashcards

When positioning CCTV cameras to capture facial recognition-quality images at an entrance, which camera placement is MOST effective?

Answer: Eye-level or slightly above, angled toward approaching subjects with adequate lighting

Cameras positioned at or slightly above eye level, facing approaching subjects with adequate frontal lighting, capture the facial detail needed for identification and forensic use.

In security system design, 'redundancy' refers to:

Answer: Installing duplicate systems or components so that failure of one does not disable the entire security function

Redundancy ensures continuity of security functions by duplicating critical components (power, communications, recording) so single points of failure do not disable protection.

Which communication path is considered MOST resilient for alarm signal transmission from a protected site to a monitoring center?

Answer: Dual-path communication using both cellular and IP/broadband simultaneously

Dual-path communication uses two independent transmission technologies simultaneously, so if one path is cut or jammed, the other still delivers the alarm signal.

A security manager is implementing a system where door alarm events automatically direct the nearest PTZ camera to the triggered door location. This integration is called:

Answer: Video verification or event-driven video

Event-driven video (video verification) automatically links alarm events to camera positioning and recording, enabling rapid visual confirmation of alarm conditions.

What is the primary legal consideration when deploying audio recording capabilities alongside CCTV surveillance in the United States?

Answer: Many US states require at least one-party or all-party consent for audio recording, which may restrict covert audio capture

Audio recording laws vary significantly by state, with some requiring all-party consent; security managers must verify compliance with applicable state wiretapping and eavesdropping statutes before deploying audio.

Which security technology standard governs the interoperability of IP-based physical security devices such as cameras and access control systems from different manufacturers?

Answer: ONVIF (Open Network Video Interface Forum)

ONVIF is an industry standard that enables IP-based security devices from different manufacturers to communicate and interoperate, reducing vendor lock-in.
