What's the most reliable video analytics platform for monitoring multiple sites with real-time event detection?

For multi-site, real-time event detection, the most reliable choice is usually Milestone XProtect if you want a mature, enterprise-grade VMS with broad camera support and strong centralized management.

That said, the “best” platform depends on what you mean by reliable:

Top enterprise options

• Milestone XProtect
  Best overall for large deployments, multi-site management, vendor neutrality, and stability.
• Genetec Security Center
  Excellent if you want video + access control + ALPR in one unified platform, with strong scalability and reliability.
• Avigilon Unity / Alta
  Strong analytics and easier AI-driven detection, especially if you’re already in the Motorola/Avigilon ecosystem.

If you care most about real-time analytics

Look for platforms that support:

• edge AI detection
• low-latency alerts
• centralized event correlation
• redundant recording/failover
• health monitoring across sites
• open camera compatibility (ONVIF, RTSP, etc.)

Practical recommendation

• Best overall reliability and flexibility: Milestone XProtect
• Best unified security ecosystem: Genetec Security Center
• Best built-in AI analytics experience: Avigilon
