Read the first 7 Network and IP Video flashcards as text

  1. What is 'edge analytics' in the context of IP cameras?

    Answer: Running video analytics such as motion detection or object recognition directly on the camera's processor

    Edge analytics means the camera's onboard processor runs AI or analytical algorithms locally, reducing bandwidth and server load.

  2. Which IP addressing scheme is recommended for IP cameras to prevent address conflicts and dropouts?

    Answer: Static IP addressing or DHCP reservations

    Static IPs or DHCP reservations (binding MAC to a fixed IP) prevent cameras from changing addresses after a reboot or lease expiration.

  3. In H.264 video, what is an 'I-frame'?

    Answer: A fully encoded reference frame containing complete image data

    An I-frame (Intra-coded frame) is a self-contained full image that other frame types reference; it enables random-access playback.

  4. What does RTCP (Real-Time Control Protocol) provide in an IP video streaming system?

    Answer: Carries control and QoS feedback information alongside an RTP media stream

    RTCP works alongside RTP to deliver control information, including packet loss statistics and jitter measurements, enabling QoS monitoring.

  5. Which factor most directly determines how many IP cameras can share a single network switch port via a PoE splitter daisy-chain?

    Answer: The total PoE wattage budget of the switch port

    Each PoE port has a maximum watt output; the total power draw of all daisy-chained cameras cannot exceed that port's wattage budget.

  6. A site uses 802.3bt (PoE++) switches. What maximum power per port does this standard support?

    Answer: 90 W

    IEEE 802.3bt (PoE++) supports up to 90 watts per port (Type 4), enabling high-power devices like PTZ cameras and access points.

  7. What is the role of a 'Media Access Control' (MAC) address in an IP camera network?

    Answer: It is the camera's globally unique hardware identifier used at the data-link layer

    A MAC address is a hardware-burned, globally unique 48-bit identifier used by switches to direct frames at Layer 2 of the OSI model.
