Product Details
✓The Revolutinary 4-Cam System: Secure your property with two 4K bullet cameras for fixed zones, two Bullet-PTZs for a 4K wide-angle overview, plus a 2K PTZ with 360° pan and 8× zoom for active tracking. AI-ISP ensures vivid color night vision with spotlights needed. NOTE: To ensure you can use our PoE NVR Security System smoothly, please make sure your eufy APP is updated to the latest version of iOS V5.0.70/Android V5.0.71 or above.
✓Live Cross-Cam Tracking: The bullet-PTZ cameras work in sync to track movement in real-time. When one camera reaches its limit, another takes over instantly, ensuring continuous, uninterrupted coverage—all under your control.
✓Seamless Integration with the eufy Ecosystem: Instantly connect your NVR PoE System with eufy battery Wi‑Fi cameras, video doorbells and sensors, enabling them to use NVR features like 24/7 recording, smart video search, AI recognition, and app control — all in one secure system.
✓Expandable Security: 8‑Port NVR that can be expanded to 16 channels via a PoE switch(no included). Supports up to 8 Bullet‑PTZ Cams (uses 2 channels each) or up to 16 Bullet/Turret Cams. Includes a pre‑installed 2 TB HDD (upgradeable to 16 TB) for 24/7 recording.
✓Local AI Agent: Unlock proactive, real-time security with our local AI agent, fueled by 6T/8-Core power for instant analysis, genuine threat identification, and decisive action. Customize no-go zones and alerts, enabling AI to accurately detect real danger and ensure tailored responses.
✓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.
✓Smart Video Search with no subscription fee: Instead of scrolling through all of your videos, instantly find what you're looking for by searching keywords.
