The AXIS P3247-LVE provides the greatest deterrence effect. This model is a robust, vandal-resistant network camera designed for outdoor use with advanced features such as IR illumination, advanced video analytics, and a rugged design. Its visible presence and high-quality image capture capabilities serve as a strong deterrent to potential intruders and vandals.

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.

“When decommissioning an Axis device, always perform a factory restore to securely remove all configuration, user data, and stored information from the device.”

— Axis Decommissioning Guide

“A factory restore erases all user data and settings, returning the device to its original state, which is necessary before removing the device from service.”

The maximum distance from a midspan to a camera requiring PoE+ (25.5 W) is 100 meters (328 feet). This distance limitation is due to the standard Ethernet cable length limit, ensuring effective power delivery and data transmission over the network.

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.

"The field of view (FOV) of a camera is determined by the focal length of the lens and the size of the image sensor. A shorter focal length gives a wider FOV, while a larger sensor size also increases the FOV."

— Axis Communications Academy, Network Video Fundamentals, 2022

"FOV = 2 × arctan (sensor size / (2 × focal length))."

"The AXIS Camera Application Platform (ACAP) enables the development and deployment of edge applications directly on Axis devices, allowing for advanced analytics and custom functionality."

— Axis Camera Application Platform Overview

"ACAP is an open platform that allows partners and users to develop and run applications on Axis network devices."

AXIS Device Manager can provide information about the camera’s uptime. This tool offers comprehensive device management features, including monitoring and reporting the operational status and uptime of Axis devices. It helps ensure that devices are functioning correctly and allows for proactive maintenance. This feature is highlighted in Axis Communications' documentation on AXIS Device Manager capabilities.

In an IP-based video system, audio can be transmitted alongside video over the same network, allowing for integrated audio-video surveillance. This enables the simultaneous monitoring of both audio and visual data, enhancing situational awareness. Additionally, some Axis video encoders support audio functionality with analog cameras, allowing these older devices to be integrated into modern IP-based systems and take advantage of audio capabilities. Axis documentation highlights these features, emphasizing the seamless integration of audio and video in IP surveillance solutions and the extended functionality provided by video encoders.

Maintenance is essential for ensuring the optimal performance of outdoor cameras running video analytics. 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.
