Seamless 180-Degree Ultra-Wide Panoramic Surveillance

The Hikvision 4 MP 180° Panoramic Dual-Lens Fixed Bullet Network Camera delivers expansive single-camera coverage designed to replace multiple traditional fixed cameras. Equipped with dual 1/2.5" progressive scan CMOS sensors and synchronized 2.8 mm lenses, the camera utilizes advanced image stitching technology to generate a seamless 180° horizontal by 81° vertical panoramic video stream (3040 × 1368 @ 24/25 fps) with natural perspective and zero blind spots.

Active Deterrence and Two-Way Audio Protection

Engineered for proactive perimeter security, the camera combines long-range night vision with on-site deterrence capabilities:

  • 40-Meter Smart IR: High-efficiency 850 nm infrared LEDs illuminate expansive perimeters up to 40 meters in complete darkness (0 Lux).
  • Active Siren and Flashing Light: Features a built-in flashing warning light and an integrated 1 W speaker (producing up to 97 dB at 10 cm) to broadcast sirens or customized voice alerts when security rules are breached.
  • Two-Way Voice Communication: Onboard microphone with environmental noise filtering and integrated speaker allow direct real-time communication via Hik-Connect or iVMS-4200, alongside dedicated audio line in/out terminal blocks.
  • 120 dB True WDR: Balances difficult backlighting across large outdoor spaces, parking lots, and building facades.

Heavy-Duty All-Metal Enclosure and Edge Storage

Constructed with an all-metal front cover, body, and integrated 3-axis mounting bracket (pan 0° to 355°, tilt 0° to 90°, rotate 0° to 360°), the camera is IP67 weather-resistant for reliable operation from -30 °C to 60 °C. It supports expandable local storage up to 512 GB via microSD and provides 1 alarm input and 1 alarm output for seamless integration with external security systems.

FAQ

How does the camera achieve a 180-degree field of view without fisheye barrel distortion?

The camera uses two separate 1/2.5" image sensors paired with precision 2.8 mm lenses. The camera's internal processor stitches the two video feeds in real time, creating a flat, seamless 180-degree panoramic aspect ratio (3040 × 1368) without curved edge distortion.
How does the active deterrence system function during an intrusion event?

When a configured security event is triggered, the camera instantly activates its onboard white flashing light to illuminate the intruder and sounds an audible siren or voice warning through its integrated 97 dB speaker to deter trespassing before damage occurs.
Does the camera support two-way audio communication?

es. The camera is equipped with both an integrated high-sensitivity microphone (with background noise filtering) and a built-in speaker, enabling clear two-way voice conversations through the Hik-Connect mobile app or iVMS-4200 software. External audio line in/out terminal blocks are also provided.
What are the installation and mounting capabilities?

Housed in an IP67-rated all-metal enclosure, the camera includes an integrated 3-axis adjustable bracket supporting 0° to 355° pan, 0° to 90° tilt, and 0° to 360° rotation for easy alignment on walls, ceilings, or outdoor poles.
