Safety and Security — FAQ
What is a PTZ camera and when do I need one?
PTZ (Pan-Tilt-Zoom) cameras remotely adjust direction and magnification, replacing multiple fixed cameras. You need one when monitoring large areas like sanctuaries, parking lots, or conference rooms where manual adjustment or automated tracking is required. They reduce installation costs by covering 500% more area than static cameras.
NDI versus IP streaming: which is better?
NDI delivers broadcast-quality, low-latency video over standard networks with automatic device discovery—superior for live production. Standard IP streaming (RTSP) offers wider compatibility with NVRs and security software but higher latency. Choose NDI for streaming, IP for surveillance.
How much optical zoom do I really need?
For conference rooms under 20 feet, 3x-5x suffices. Church streaming requires 12x-20x to capture facial expressions from the back of the sanctuary. Security applications need 20x-50x for license plate and facial recognition beyond 100 feet. Measure your space and multiply by two for safety.
Is PoE necessary for PTZ camera installation?
PoE (Power over Ethernet) eliminates separate electrical runs, cutting installation costs by 40% and enabling centralized power backup. It's essential for outdoor cameras and large deployments. Most pro-grade PTZ cameras require PoE+ (25.5W) for IR illuminators and heaters—verify your switch capacity.
How accurate is AI auto-tracking in crowded spaces?
Gen 3 AI tracking maintains 95% accuracy with up to five people in frame by using pose estimation and color matching. It struggles with similar clothing or rapid subject handoffs. For worship services, pre-set manual shots often supplement tracking during processions or crowded altar scenes.
Can I use a PTZ security camera for live streaming?
Security cameras prioritize IR night vision and AI detection over image processing, producing flatter colors and slower exposure adjustments unsuitable for professional streaming. Streaming cameras feature NDI, better auto-white balance, and lower latency. Hybrid models exist but compromise on both fronts.
