IP camera Hikvision DS-2CD2146G2H-ISU (2.8mm) AcuSense 4 MP vandal-resistant

Hikvision DS-2CD2146G2H-ISU (2.8mm) AcuSense 4 MP vandal-resistant is a fixed-lens IP camera engineered for indoor and outdoor video surveillance. The camera captures 4 MP resolution video with a 2.8 mm wide-angle lens, and integrates AcuSense analytics for reliable intrusion and line-crossing detection. Its vandal-resistant housing and weather-tolerant design make it suitable for monitoring entrances, parking areas and other public or commercial spaces that require continuous, high-detail imaging and tamper resistance.

Advantages

This camera delivers high-resolution 4 MP imaging combined with a fixed 2.8 mm lens for broad scene coverage and clear detail. AcuSense analytics reduce false alarms by distinguishing human and vehicle targets from other motion, enabling focused event detection for intrusion and line-crossing scenarios. The vandal-resistant housing improves durability in exposed locations and reduces maintenance needs caused by tampering or external impact. PoE compatibility and standard network video features ensure straightforward integration with IP-based recording and monitoring systems.

Suitable for

• Entrance and access control monitoring in commercial buildings
• Parking lots and garage surveillance
• Perimeter and walkway monitoring with line-crossing detection
• Public spaces and small outdoor areas requiring tamper resistance
• Indoor halls and corridors where wide-angle coverage is needed

Key specifications

• Image sensor: 4 megapixel resolution
• Lens: fixed 2.8 mm wide-angle
• Analytics: AcuSense with intrusion and line-crossing detection
• Housing: vandal-resistant (IK-rated body designed for tamper resistance)
• Environmental: suitable for indoor and outdoor installation with weather protection
• Video features: network IP streaming, H.265/H.264 compression support
• Connectivity: Power over Ethernet (PoE) support for simplified installation

How to use

Install the camera at a fixed mounting point with a clear view of the intended coverage area. Connect the device to the network using an Ethernet cable; use PoE-enabled switches or injectors to supply power and network connectivity over a single cable. Configure the camera through the provided web interface or compatible video management software to set resolution, frame rate and encoding. Enable AcuSense analytics and define intrusion or line-crossing detection zones, adjusting sensitivity to the scene to balance detection accuracy and false alarm reduction. Ensure the camera angle and focus provide the desired coverage before finalizing the mount.

Usage recommendations

For best detection performance, mount the camera at a height and angle that provide unobstructed views of entry points and travel paths; avoid pointing directly at reflective surfaces or strong backlighting. Regularly check firmware updates and calibrate analytics settings to adapt to seasonal or environmental changes in the monitored scene.
