The AXIS Q6315-LE is a PTZ (Pan-Tilt-Zoom) camera. This type of camera is capable of panning, tilting, and zooming to provide flexible and comprehensive surveillance coverage. PTZ cameras are often used in applications requiring dynamic monitoring of large areas, allowing operators to zoom in on specific details or track moving objects. Axis Communications' product catalog confirms the AXIS Q6315-LE as a PTZ camera.
Question 18
Which is true for a multidirectional camera?
Options:
A.
The lenses move automatically when tracking an object
B.
Each sensor is assigned its own IP address
C.
The sensors are movable to enable optimal usage
D.
The image from each sensor is automatically dewarped
Answer:
C
Explanation:
A multidirectional camera is equipped with multiple sensors that can be independently adjusted to cover different areas. This flexibility allows for optimal usage of the camera by positioning each sensor to capture specific scenes or angles. These sensors are typically fixed in place once set up, but their initial placement can be adjusted to ensure comprehensive coverage. Axis documents specify that multidirectional cameras are designed for customizable installation to meet varying surveillance needs.
Question 19
Which layer 4 protocol has less overhead information?
Options:
A.
UDP
B.
TCP
C.
HTTP
D.
IP
Answer:
A
Explanation:
UDP (User Datagram Protocol) has less overhead information compared to TCP (Transmission Control Protocol). UDP is a simpler, connectionless protocol that does not require handshaking or error-checking mechanisms, resulting in lower overhead and faster transmission of data. This makes UDP more efficient for real-time applications such as video streaming, as detailed in Axis Communications' technical guides on network protocols.
Question 20
Which cameras have IR LED illumination built-in? (select two)
Options:
A.
AXISM1135-E
B.
AXISQ1951-E
C.
AXIS M3057-PLVE Mkll
D.
AXISQ3615-VE
E.
AXIS P1378-LE
Answer:
C
Explanation:
AXIS M3057-PLVE MkII and AXIS P1378-LE both have built-in IR LED illumination. This feature is crucial for enhancing visibility in low-light conditions or complete darkness, making them suitable for various surveillance applications. The built-in IR LEDs ensure that these cameras can provide clear images even in challenging lighting environments.References: AXIS M3057-PLVE MkII, AXIS P1378-LE
