⚡ At a Glance

• Image Quality: 2560 x 1440 resolution with dual lenses (telephoto + wide) and up to 8× digital zoom, including color night vision
• Developed for: Homeowners and property managers who want continuous outdoor surveillance with bright, motion-activated lighting
• Harder for: Small business owners needing multi-week offsite evidence retention; relying on a local memory card without HomeBase S380 forces manual backups and complicates long-term archival

Dual‑lens optics and 2,000 lumens of adjustable lighting deliver clear day and color night footage. Local storage works out of the box, with expandable retention when paired with HomeBase S380.

Dual-Lens 360° PTZ: The Professional's Verdict

Dual lenses combine a telephoto view and a wide-angle sensor at 2560 x 1440 resolution, while on-device AI executes person detection and 360° pan/tilt tracking with up to 8× digital zoom. Direct impact: the system keeps a moving subject centered and readable from across a driveway or yard.

Precise tracking delivers usable identification at distance without constant manual control. If you require uninterrupted mechanical motion in dusty or coastal environments, schedule periodic inspection for the pan/tilt assembly to maintain smooth tracking.

Mastering Nighttime Identification via 2,000-Lumen Floodlight

Adjustable 2,000‑lumen LED floodlight pairs with color night vision to preserve detail in low light while two‑way audio and a built‑in siren add active deterrence. User scenario: when motion triggers the lights, faces and license plates remain legible in the recorded footage.

Bright, controllable illumination reduces false negatives common to monochrome night capture and improves evidence value. A clear trade-off exists: the intense lighting may draw attention from neighbors and requires mindful placement to avoid nuisance glare.

Local-First Recording for the Modern User

Supports 24/7 continuous recording to a memory card and expands storage when connected to HomeBase S380 (HomeBase 3). Dual-band Wi‑Fi 6 connectivity enables higher throughput for live view and simultaneous streams.

On-site retention keeps footage under your control and minimizes recurring cloud obligations, while HomeBase S380 enables longer archival windows. If offsite, multi-week evidence storage is a must, pair the system with HomeBase S380 to avoid manual file management.
