Extra Info
Zoom & PTZ Control
This camera features 4× optical zoom and full PTZ functionality—with 355° panning and 90° tilting—enabling broad area surveillance and precise zoom-in tracking. Whether you're monitoring a wide parking lot or focusing on a gate or pathway, it supports preset patrol routes, pattern memory, and manual control for active, real-time tracking of subjects.
Smart Video Analytics (IVS)
The built-in Intelligent Video Surveillance (IVS) suite includes tripwire, intrusion detection, and face detection. These AI-enhanced features differentiate actual threats from everyday motion (like shadows or small animals), helping minimize false alarms. Face capture can also be linked to alarms or bookmarked for fast post-event review—ideal for commercial or public access points.
Privacy Masking for Compliance
To comply with privacy regulations, the camera allows you to draw up to 24 independent privacy masks. These areas are permanently blurred in the video feed to block out sensitive zones such as windows, private property, or areas not under surveillance jurisdiction—crucial for GDPR or similar privacy compliance.
Smart Compression Technology (H.265)
Utilizing Smart H.265 video encoding, the camera dynamically adjusts compression settings based on scene complexity. It preserves detail in active zones while lowering the bitrate in static areas, which can reduce bandwidth and storage needs by up to 70%—without noticeable loss in quality. This makes it suitable for installations requiring long video retention or cloud uploads.
Rugged Outdoor Build
Built with a metal housing, this camera is ready for harsh outdoor environments. It carries an IP66 weatherproof rating to protect against rain and dust, and an IK10 vandal-resistance rating to withstand physical impact or tampering. These features make it ideal for public spaces, transport hubs, construction sites, or any exposed area.
Q&A
Q: Can it see in complete darkness?
A: No built-in IR—requires external lighting for night clarity.
Q: Does it support two-way audio?
A: No; this model lacks audio mic or speaker.
Q: Will it work with third-party NVRs?
A: Yes—ONVIF and CGI compatibility enables VMS/NVR integration.
Q: How long can a 128 GB microSD card record?
A: Roughly 7–10 days continuous recording at high-res, more with smart compression and lower frame rates.
Q: Is there a Pro version with siren/lights?
A: Not for this model—it focuses on core PTZ and analytics. Active deterrence is available in other families.
Q: Can the camera automatically patrol?
A: Yes, it supports preset tours, scans, and patterns for automated coverage.
