The DS-2CD2043G2-IU is a 4MP AcuSense bullet camera designed for commercial perimeter monitoring, outdoor entrances, loading areas, drive lanes, and other locations that require focused long-range coverage.
Its 4 mm fixed lens provides a narrower viewing angle suited to monitoring defined areas such as access roads, exterior walkways, parking entrances, perimeter walls, and building approaches. Human and vehicle classification helps make supported motion and perimeter events easier to review.
The built-in microphone adds synchronized audio recording through compatible systems, while the IP67-rated housing supports properly installed outdoor applications. Recommended for warehouses, distribution centers, commercial buildings, apartment parking areas, industrial properties, and retail service entrances.

Find answers to common questions about compatibility, installation, infrared night vision, recording storage, and AcuSense human and vehicle classification.
Is this 4MP AcuSense bullet camera compatible with H-Series NVR systems?
Yes. The camera is designed to work with H-Series NVR systems and supports advanced recording, event management, and remote monitoring. It also supports ONVIF Profile S and Profile G, making it compatible with many third-party NVRs and video management systems.
What image quality can I expect from the 4MP resolution?
The camera captures video at up to 2688 × 1520 resolution, providing clear images with enough detail to identify people, vehicles, and important events. It offers a good balance between image quality, storage efficiency, and network bandwidth.
Does the camera support AI human and vehicle detection?
Yes. Built-in AcuSense analytics can distinguish people and vehicles from general motion. This helps reduce unnecessary alerts caused by animals, moving trees, weather, or shadows, allowing you to focus on events that are more likely to require attention.
Can I use this camera with a third-party NVR?
Yes. The camera supports ONVIF Profile S, Profile G, ISAPI, and SDK integration, making it compatible with many third-party NVRs, video management systems, and professional surveillance platforms.
How far can the infrared night vision reach?
The built-in smart infrared illuminator provides night vision up to 40 meters (about 131 feet). Smart IR automatically adjusts the illumination level to help reduce overexposure when people or vehicles move close to the camera.
Does this camera support audio recording?
Yes. The -U version includes a built-in microphone that records synchronized audio with video. Audio can provide additional context during investigations by capturing conversations or environmental sounds that video alone may not reveal.
Can the camera record directly to a microSD card?
Yes. The built-in microSD card slot supports cards up to 512GB, allowing local recording without relying entirely on an NVR. It also supports NAS storage and Automatic Network Replenishment (ANR) for additional recording flexibility.
Does the camera support Power over Ethernet (PoE)?
Yes. The camera supports IEEE 802.3af PoE, allowing power and network connectivity through a single Ethernet cable. This simplifies installation, reduces cable clutter, and makes deployment easier for both new and existing surveillance systems.
Is this camera suitable for outdoor installation?
Yes. The IP67 weatherproof rating protects the camera from rain, dust, and harsh outdoor conditions. It is suitable for residential and commercial installations such as driveways, loading docks, parking lots, warehouses, and building perimeters.
What types of properties is this bullet camera best suited for?
This camera is a good choice for homes, retail stores, offices, warehouses, apartment buildings, schools, and small businesses. Its long-range infrared lighting, AI detection, and weather-resistant design make it well suited for monitoring entrances, fences, parking areas, and outdoor walkways.
