What does the phrase 'High Availability' refer to in the context of XProtect?

The concept of 'High Availability' in the context of XProtect refers specifically to ensuring that the surveillance system is operational and accessible at all times. This is crucial for security systems, where continuous monitoring and recording are essential to maintain safety and security. High Availability typically involves implementing redundant components, failover mechanisms, and reliable network configurations to minimize downtime and ensure that the system can recover quickly from any failures. This way, users can rely on the surveillance system to be functional whenever it is needed, thereby enhancing the overall effectiveness of the security measures in place.

The other options do not directly address the core principle of High Availability. While multiple user accounts with accessibility might be important for user management, it does not pertain to system reliability. Similarly, reducing costs or enhancing video quality are separate objectives that do not define High Availability, which is fundamentally about maintaining constant system access and operational reliability.
