  1. Which legal doctrine requires law enforcement to obtain a warrant before using a device that detects heat signatures inside a private home?

    Answer: Kyllo v. United States ruling

    The Supreme Court's Kyllo v. United States (2001) held that using thermal imaging to detect activity inside a home constitutes a Fourth Amendment search requiring a warrant.

  2. An IP camera with PoE (Power over Ethernet) capability means it:

    Answer: Receives both data and electrical power through the network cable

    PoE technology allows a single Ethernet cable to simultaneously carry data and supply electrical power to the camera, simplifying installation.

  3. In video surveillance, 'looping' recordings refers to:

    Answer: Overwriting the oldest footage when storage is full

    Looping (or loop recording) automatically overwrites the oldest stored footage when storage capacity is reached, ensuring continuous recording.

  4. What is the primary purpose of a 'privacy mask' feature in surveillance camera software?

    Answer: To block recording of specific areas within the camera's field of view

    Privacy masks are configurable zones within a camera's view that are blacked out in the recording, protecting areas where privacy must be maintained.

  5. Which technique do investigators use to correlate footage from multiple cameras to track a subject's movement through a facility?

    Answer: Forensic timeline reconstruction

    Forensic timeline reconstruction involves reviewing footage from multiple camera sources and chronologically sequencing appearances to establish a subject's path.

  6. A surveillance system using RTSP (Real Time Streaming Protocol) is primarily designed for:

    Answer: Streaming live video over IP networks

    RTSP is a network control protocol designed to establish and control media streaming sessions for live video delivery over IP networks.

  7. During a covert mobile surveillance operation, an investigator should avoid:

    Answer: Maintaining a fixed following distance

    Maintaining a fixed following distance is a surveillance detection indicator; skilled subjects will notice a vehicle that consistently maintains the same gap.
