Please note: The Add-on Camera is designed to work exclusively with eufy NVR S4 and cannot function on its own.   16 MP Triple-Lens Bullet-PTZ Camera: The upper 4K wide-angle camera provides a 122° fixed view of the entire scene, while the lower 2K PTZ camera features 8× auto-zoom and 360° pan for complete coverage. Auto-Framing and Group Tracking: When the bullet camera detects a subject, the PTZ locks on and auto-tracks them in sharp, centered close-ups from up to 164 ft away. Auto-zoom keeps moving subjects framed until they exit view. Starlight Color Night Vision: See colorful nighttime details with AI-ISP processing—no spotlight needed. Activate a spotlight for a clearer view and use HDR to prevent overexposure, allowing you to even identify a license plate. Red and Blue Strobe: AI expertly tracks intruders to defend your property and deters threats with smart sirens and a red and blue strobe to give you peace of mind. AI Human Detection: Advanced AI distinguishes between people, pets, and vehicles to reduce false alerts by 99%, so you only get notified when it matters. 24/7 Recording with PoE: A single cable handles power and data for 24/7 recording and complete peace of mind with your eufy NVR S4. Note: PoE NVR, switch, injector, and DC adapter required (not included). IP65 and Two-Way Talk: Withstands any weather with robust IP65 waterproofing for reliable monitoring.
