Extra Info
Starlight Performance & Low-Light Clarity
An ultra-sensitive Starlight sensor enables this camera to maintain vivid colours and detail even in near-darkness, ideal for properties, driveways, or perimeters with poor lighting.
True 1080p with Motorised Lens
Remote control of the 2.7–12 mm auto-iris lens ensures accurate framing and sharp focus without physical adjustments — perfect for variable scenes or multi-site installations.
Smart IR Illumination
Equipped with four IR LEDs and Smart IR, the camera ensures consistent illumination during night vision—bright enough at long distances yet prevents IR washout at close range.
Flexible Video & System Interfaces
Dual BNC ports allow simultaneous HD (CVI) and analog (CVBS) output, with additional SDI. Also includes OSD menu control over coax, microphone input, and alarm triggers.
Long-Distance HD Transmission Over Coax
HD‑CVI allows simultaneous video, power, audio, and control via a single coax cable—supporting up to 800 m for 1080p signal with ultra-low latency.
3D Noise Reduction & Electronic Defogging
Advanced 2D/3D NR and defog modes help clean video under challenging environmental conditions, improving clarity in foggy or dusty installations.
Ultra-Rugged Build for Harsh Environments
Rated IP67 for water/dust resistance and IK10 for impact protection. Built to endure extreme temperature fluctuations, voltage variability (±25%), and lightning surges.
Elegant, Low-Profile Design
Featuring a discreet dark-glass faceplate and sleek aluminium body, this camera blends into modern environments while conveying a professional, project-grade aesthetic.
Q&A
Q: Does this camera provide true 1080p video?
A: Yes — it offers up to 30 fps at full HD 1080p resolution with accurate detail and minimal latency.
Q: Can I change the zoom or focus remotely?
A: Yes. The motorised 2.7–12 mm auto-iris lens supports remote zoom and focus via the DVR or coax OSD, ideal for flexible positioning.
Q: How far can it see at night?
A: The Smart IR LEDs provide illumination up to approximately 100 meters, balancing brightness across close and distant scenes.
Q: Is it vandal-resistant?
A: Yes. With IK10-rated housing, it can resist impacts equivalent to a 55 kg force (~120 lbs).
Q: Can I upgrade from analog without rewiring?
A: Absolutely. HD‑CVI supports HD video and control over existing coaxial cables, making upgrades straightforward and cost-effective.
Q: Can it integrate with alarms or audio systems?
A: Yes. It includes a built-in audio input and alarm in/out ports, enabling integration with sirens, sensors, or intercom devices.
