The 3.7–11mm lens offers slightly more zoomed-in views with a narrower wide-angle range, ideal for medium-range monitoring.
Q: Can this be used in areas prone to vandalism?
Yes—an optional IK10-rated model offers added protection against impacts or tampering.
Q: Does it support smart analytics like Tripwire?
Yes—built-in IVS features include Tripwire and Intrusion detection for event-based alerts.
Q: Can the IR LEDs be manually adjusted or disabled?
Yes—IR can be turned on/off manually, or set to auto based on lighting conditions.
Q: Is the lens adjustable remotely?
Yes—the motorized varifocal lens allows zoom and focus adjustments via NVR or app.
Q: Will this work with a third-party NVR?
Yes—it's ONVIF compatible, so it integrates with most major NVR brands.
Q: How long can a 128GB SD card record?
With Smart H.265+ compression, a 128GB card can typically store several days of footage depending on motion activity and settings.
