Get Certified: Proven Methods to Pass the Axis Communications ANVE Exam

A video encoder effectively turns an analog camera into a network camera by converting the analog signal to a digital format, which can then be transmitted over a network. Additionally, video encoders add intelligent functionality found in network cameras, such as motion detection, event management, and video analytics capabilities. These features enable legacy analog systems to integrate with modern IP-based surveillance solutions. References: Axis Communications product documentation on video encoders.

If an object is placed 1 meter (3 feet) away from a light source with a lux level of 3200 lux, the lux level decreases according to the inverse square law of light. At a distance of 8 meters (24 feet), the lux level can be calculated as:

New Lux Level=3200 lux(8/1)2=3200 lux64=50 lux\text{New Lux Level} = \frac{3200 \text{ lux}}{(8/1)^2} = \frac{3200 \text{ lux}}{64} = 50 \text{ lux}New Lux Level=(8/1)23200 lux​=643200 lux​=50 lux

Thus, at 8 meters, the light intensity drops significantly to 50 lux.

Axis Secure Remote Access simplifies making Axis cameras available over the internet without the need for complex network configurations. This service provides a secure, encrypted connection to access and manage Axis devices remotely. By using Axis Secure Remote Access, users can avoid issues related to NAT traversal and firewall configurations, ensuring a reliable and secure remote connection. Detailed instructions and benefits of using Axis Secure Remote Access are outlined in Axis' support documentation.

The reason why the camera is not blinded by the headlights is that an IR-pass filter is in use. This filter blocks out visible light, including the bright headlights, and allows only infrared light to pass through. This is particularly useful in nighttime surveillance scenarios where the camera can rely on infrared illumination instead of visible light, ensuring clear visibility even in the presence of bright lights like headlights.

A PoE switch with a power budget of 90 W can power 12 class 2 devices. Class 2 PoE devices typically require up to 7.5 W each. By dividing the total power budget (90 W) by the power requirement per device (7.5 W), we get 12 devices. This calculation aligns with the PoE standards defined in IEEE 802.3af/at, as outlined in Axis Communications' technical resources.

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

On layer 3 of the OSI model, the protocol that enables network traffic is IP (Internet Protocol). IP is responsible for addressing and routing packets of data so that they can travel across networks and reach the correct destination. It provides logical addressing and handles the path through which data is transferred between source and destination nodes. Axis documentation confirms that IP is crucial for network communication and is fundamental for the operation of network video systems.

The primary purpose of the accessory on this dome camera is to reduce the weather impact. This accessory, often referred to as a weather shield or rain guard, helps protect the camera lens from rain, snow, and other environmental elements, ensuring clear visibility and reducing the need for maintenance. It also helps to minimize the impact of direct sunlight, reducing glare and improving image quality.References: Axis Dome Camera Accessories

Video analytics applications detect movement perpendicular to the camera more easily than movement toward or away from the camera. This is because objects moving perpendicular to the camera create more significant changes in the pixel patterns, making it easier for the analytics software to detect and analyze the movement. Movement toward or away from the camera results in smaller changes in pixel patterns, which can be harder to detect accurately. References: Axis Communications documentation on video analytics and movement detection.

The field of view of a camera is determined by the focal length of the lens and the size of the sensor. The focal length affects how wide or narrow the view appears, while the sensor size impacts the overall field of view captured by the camera. Axis technical specifications detail how different combinations of focal length and sensor size influence the camera's field of view, allowing for precise control over what is captured in the frame.
