Dahua DH-H4A 4MP Indoor Wi-Fi Pan & Tilt IP Camera (3.6mm), 2K 2560×1440@25fps, H.265, Human Detection + Auto Tracking, IR Night Vision 15m, Two-Way Audio, microSD 256GB, RJ45 Ethernet

The Dahua DH-H4A is a 4MP indoor fixed-focal Wi-Fi pan & tilt network camera designed for practical room coverage in homes and small to medium business environments. It is built to provide clear indoor monitoring, flexible pan/tilt control, and intelligent detection features that help keep users aware of meaningful activity. Typical use cases include monitoring small retail areas, reception zones, office rooms, storage rooms, corridors, living rooms, entry halls, and other indoor spaces where a single camera needs to cover a wide area without requiring multiple fixed cameras.

At the image capture level, the DH-H4A uses a 1/3" CMOS image sensor and outputs up to 4MP resolution at 2560 × 1440. The camera supports a maximum output of 2560 × 1440 at 25 frames per second on the main stream, delivering 2K-class detail that is well suited for identifying objects and people during playback review. Video compression uses the H.265 codec, which is designed to reduce storage consumption and network load compared with older compression methods while maintaining usable quality for recording and live view. The supported sub stream resolution is VGA (640 × 480) at 25 fps, which can be used for bandwidth-efficient remote viewing or multi-client monitoring scenarios.

One of the core strengths of this model is full coverage of a room through pan and tilt movement. The DH-H4A supports a pan range from 0° to 355° and a tilt range from -5° to +80°. This allows the camera to scan across a broad area and adjust vertically to cover both near and far parts of the scene, depending on mounting position and room layout. When used with tracking functions, the pan/tilt movement helps keep a detected subject within the visual range instead of letting the subject walk out of frame like a fixed camera.

For detection and notifications, the DH-H4A supports motion detection and human detection. Motion detection is configurable and can be turned on or off, with support for up to four rectangular detection areas. Human detection helps focus alerts on people rather than general movement, which can reduce nuisance notifications in many indoor environments. The camera also supports auto tracking, which means once a target is detected, the camera can use pan and tilt to automatically follow that target as it moves, keeping the subject in view and improving the usefulness of recordings for incident review. This is especially helpful in small retail stores or indoor areas where movement may happen across the room and you want continuous visual coverage.

Day and night operation is supported through multiple modes: Auto (ICR), Color, and B/W. In normal lighting, the camera provides color images, and when illumination is inadequate it switches to night mode and provides black-and-white images. For low-light monitoring, the camera includes a built-in IR LED. The IR illumination distance is specified up to 15 meters, supporting monitoring in dark indoor rooms or after business hours when lights are off. IR on/off control is automatic, allowing the camera to switch infrared behavior as needed based on the environment.

Audio support is a practical feature for indoor monitoring. The DH-H4A includes a built-in microphone and a built-in speaker, enabling two-way talk functionality through the mobile app. Two-way talk can be used for basic communication with staff or family members, responding to visitors, or issuing an audible warning when suspicious activity is detected—depending on how the system is used in the environment.

For storage, the camera supports a microSD card slot with support up to 256GB. This enables local recording directly to the camera (microSD card not included unless bundled by seller), which can be useful for users who want recording without a separate recorder. Local storage also provides a simple approach for small setups where a compact, self-contained camera system is preferred.

Networking and management options support flexible deployment. The DH-H4A supports Wi-Fi connectivity using IEEE 802.11b/g/n on the 2.4 GHz band (2.4–2.4835 GHz). For users who prefer wired stability, it also includes an RJ-45 network port supporting 10/100 Base-T Ethernet. The mobile client supports iOS and Android, and the listed management software is DMSS, which is commonly used for Dahua consumer and SMB monitoring workflows.

The camera uses a fixed focal lens of 3.6mm with an aperture of F2.0. The field of view for the 3.6mm lens is specified as 74° horizontal, 41° vertical, and 88° diagonal. This lens choice and field of view are intended to provide a practical balance between coverage and subject size within typical indoor distances. The camera supports DWDR (digital wide dynamic range), which helps manage scenes where parts of the image are brighter than others, such as indoor areas with windows or bright indoor lighting. Image rotation is supported at 0° or 180°.

Power is provided through a 5 VDC, 1A power supply. Basic power consumption is specified at 1.8W, and maximum power consumption is specified at 3.6W under conditions including video streaming, IR, and PTZ rotation. This supports efficient operation for always-on indoor monitoring.

In terms of build, the casing material is plastic. Product dimensions are specified as φ77.8 mm × 108.1 mm, and net weight is specified as 204.2 g. These compact dimensions make it suitable for shelf placement, table placement, or indoor mounting where space is limited.

Ordering information listed for this series includes DH-IPC-H4AP-0360B / IPC-H4AP-0360B as the 4MP Indoor Fixed-focal Wi-Fi Pan & Tilt Network Camera model. An accessory listed is a 5 VDC 1A power adapter (A806A-050100U-EU1), and an optional accessory is a microSD memory card (TF-C100).

If you need an indoor pan & tilt Wi-Fi camera that combines 4MP 2K detail, human detection and auto tracking, IR night vision for dark rooms, two-way audio communication, and local microSD recording up to 256GB—with the option of either Wi-Fi or wired Ethernet—the Dahua DH-H4A is built for small indoor surveillance deployments where coverage, practicality, and easy daily monitoring matter.
