Smart Shield Systems

4K 8MP 2.8-12mm Vari-Focal Lens

A flexible, pro-grade 4K (8MP) camera with a motorized 2.8–12 mm lens so we can zoom and focus from the app/NVR—no ladder re-aiming. Expect efficient H.265/H.265+, True WDR (≈120 dB) for backlit scenes, rugged outdoor ratings, and long-range IR for clear video day and night.

Why Choose This with Smart Shield Systems

  • Dial-in framing remotely (wide overview to tighter detail) using the motorized 2.8–12 mm lens.

  • Expert tuning of WDR, IR, and bitrate so faces, entrances, and vehicle lanes look great day and night.

Key Features

  • 4K Ultra HD (8MP) imaging with efficient H.265/H.265+ compression.
  • Motorized 2.8–12 mm lens with horizontal FOV ~108° to ~30° (model dependent).
  • True WDR ≈120 dB to handle bright doorways and mixed lighting.
  • IR night vision typically up to ~40 m (131 ft); some bullet models reach ~60–80 m.
  • Rugged build: many units are IP67 weather-sealed and IK10 vandal-resistant (domes).
  • Edge storage: microSD slot on many models (often up to 256–512 GB).

Product Specifications (At-a-Glance)

  • Resolution / Rate: up to 3840×2160 (model-dependent 20–30 fps)
  • Lens / FOV: 2.8–12 mm motorized, ~108°–30° horizontal FOV range
  • Low light: 0 lux with IR; IR to ~40 m typical (select bullets ~60 m+)
  • Compression: H.265/H.265+ (vendor dependent)
  • Power / Network: PoE (802.3af); Ethernet 10/100
  • Rugged: IP67 weather rating; IK10 on vandal-resistant domes

Compatibility Notes

  • Works with most modern NVR/VMS platforms via ONVIF (Profile S); we’ll verify specific stream/event mapping for your recorder.
  • Available in dome, turret, and bullet housings; we’ll spec the form factor and exact datasheet for your site.

Popular Use Cases

  • Entrances & lobbies: start wide, then tighten view to capture faces with WDR against bright doors.
  • Driveways, gates & alleys: zoom to lanes or choke points; use longer-range IR on bullet variants.
  • Loading zones & small lots: adjust focal length seasonally without moving the camera.

Frequently Asked Questions

A lot. You can go from a wide ~108° view at 2.8 mm to a tighter ~30° view at 12 mm—perfect for dialing in doors, lanes, or cash wraps.

Very well for typical scenes: integrated IR is commonly rated to ~40 m (131 ft), and some 8MP bullets list up to ~60–80 m. We tune exposure and IR to avoid washout.

No—PoE carries power and data over one Ethernet cable.

Many models include a microSD slot (often 256–512 GB) for edge backup; we usually pair this with NVR storage for redundancy.
