## Long description

Dahua Technology DHI-ARD1731-W2(868) is an indoor IP security camera designed for wall-mounted monitoring in homes and small business environments. The device features wireless connectivity and a CMOS image sensor capable of producing images up to 1600×1200 resolution, with support for additional output resolutions such as 1280×960, 640×480 and 320×240. The housing is made of ABS and polycarbonate in white, and the camera integrates PIR motion sensing and built-in two-way audio for direct interaction with people in the camera's field of view.
Advantages
The camera combines a high-resolution CMOS sensor with wireless networking to simplify installation without sacrificing image detail. Integrated PIR sensing reduces false alarms by detecting heat-based motion, while two-way audio lets users speak and listen through the device for remote interaction. The ABS and polycarbonate housing offers a lightweight but durable enclosure suitable for indoor wall mounting, and support for multiple lower resolutions allows adaptive streaming to conserve bandwidth or to match recording device capabilities.
Suitable for
 Indoor home monitoring of living areas, entrances and hallways
 Small office surveillance and reception areas
 Remote interaction with visitors or staff using two-way audio
 Situations requiring motion-triggered alerts using PIR sensing

How to use
Mount the camera on an indoor wall at a height and angle that provides the desired field of view. Connect the device to the local wireless network following the manufacturer's pairing procedure and configure video stream settings to the preferred resolution and bitrate. Enable PIR motion detection and configure alert parameters to receive notifications when movement is detected. Use the two-way audio feature through the camera's client app or management software to communicate with people near the camera. Ensure the unit is powered according to the supplied instructions and placed away from direct sources of heat that could affect PIR sensing.
Usage recommendations
For reliable performance, place the camera where it has an unobstructed view of the monitored area and a stable wireless signal. Choose a resolution that balances detail and network bandwidth, and test PIR sensitivity and audio levels after installation to reduce false alarms and ensure clear communication.
