Axis Communications has integrated Sharpdome technology into several of their PTZ camera models, as explained in their product specifications and technical white papers.
NEW QUESTION # 23
Which technology can a Video Management Software (VMS) partner incorporate to reduce the impact on recorded video during server maintenance?
- A. AXIS Camera Application Platform (ACAP)
- B. SNMP
- C. Local storage at the camera
- D. Meta data stream
Answer: C
Explanation:
To reduce the impact on recorded video during server maintenance, Video Management Software (VMS) partners can incorporate local storage at the camera. This feature allows the camera to continue recording video on its internal storage (such as an SD card) during network or server downtime, ensuring continuous video capture. Once the server is back online, the recorded footage can be transferred back to the central storage. Axis cameras support local storage options, which are detailed in Axis Communications' product documentation and VMS integration guides.

Regular maintenance tasks include cleaning the camera lens, checking and updating firmware, inspecting connections, and verifying that analytics software is functioning correctly. These activities help maintain image quality and ensure the accuracy and reliability of the video analytics. Axis installation and maintenance guides recommend routine maintenance to prevent performance degradation and extend the lifespan of the equipment.
NEW QUESTION # 27
Lowering the shutter speed can produce
- A. increased noise.
- B. a darker image.
- C. motion blur.
- D. reflections.
Answer: C
Explanation:
Lowering the shutter speed can produce motion blur because the camera sensor is exposed to light for a longer period, capturing the movement of objects within the frame. This results in a blurry representation of moving objects, which can be useful for artistic effects but undesirable for capturing fast-moving subjects clearly.

It facilitates communication between endpoints, whether they are directly connected or through a SIP trunk. Axis Communications' technical documentation on SIP and VoIP solutions confirms these uses.
NEW QUESTION # 29
The main benefit of using Power over Ethernet (PoE) is that
- A. the installation costs less.
C the installation consumes less power. - B. the installation is less sensitive to interference.
- C. the installation is more secure.
Answer: A
Explanation:
The main benefit of using Power over Ethernet (PoE) is cost reduction in installation. PoE allows network cables to carry both data and power, eliminating the need for separate power lines and reducing the amount of cabling required. This simplifies installation, reduces material costs, and allows greater flexibility in camera placement. Axis Communications notes that PoE significantly cuts down on installation expenses by streamlining the infrastructure needed for network devices.

NEW QUESTION # 32
A P-iris lens is
- A. An iris with higher light sensitivity.
- B. A DC-iris with feedback.
- C. An iris specially made for zoom lenses.
- D. Axis' standard for DC-iris.
Answer: B
Explanation:
A P-iris lens is a type of DC-iris lens that incorporates feedback to maintain optimal image quality. Unlike a standard DC-iris, which only adjusts based on light levels, a P-iris lens uses a feedback mechanism to optimize the iris position, ensuring consistent image sharpness, depth of field, and optimal contrast. This technology allows for precise control over the iris, which is especially beneficial in varying lighting conditions. According to Axis documentation, P-iris lenses are designed to deliver better performance by continuously adjusting the iris for optimal image quality.

NEW QUESTION # 35
Which is true about a MAC address? (Select two)
- A. It is used for direct data exchange within a network
- B. It is a logical address
- C. It is a layer 3 protocol
- D. DHCP servers can assign dynamic MAC addresses
- E. It is a unique physical address
Answer: E
Explanation:
A MAC (Media Access Control) address is a unique physical address assigned to network interfaces for communication on the physical network segment. It is used for direct data exchange within a network, ensuring that data packets are delivered to the correct device. Unlike IP addresses, MAC addresses operate at the data link layer (Layer 2) of the OSI model and are hard-coded into the network interface card (NIC) by the manufacturer. References: Axis Communications networking guides and standard networking principles.
NEW QUESTION # 36
Which statement is true for broadcast network traffic?
- A. Broadcast is a method for sending video to many recipients over the internet even though their bandwidths vary
- B. Broadcast data packet length is longer than normal Ethernet packets, to accommodate a full video frame
- C. Broadcast is designed to enable optimized video transmission, since it tolerates network dropouts
- D. Broadcast is not practical for network video transmission, since packets are transmitted to every device on the network
Answer: D
Explanation:
Broadcast network traffic involves sending data packets to all devices on a network segment, regardless of whether they need the data. This method can lead to unnecessary network congestion and is not efficient for video transmission, which typically requires sending data to specific recipients. Broadcast is generally avoided in network video transmission in favor of more efficient methods like Unicast or Multicast. [Reference: Axis Communications - Network Traffic Management]
