Telecamera di sorveglianza DAHUA SD1A404DB-GNY-W telecamera IP

The DAHUA SD1A404DB-GNY-W IP Camera is a 4 MP surveillance camera with a 1/2.8" CMOS sensor, motorized zoom lens and PTZ functionality. It records up to 2560 × 1440 resolution, supports H.265/H.264 compression, offers three video streams, and includes Wi‑Fi (2.4 GHz) and local storage options (Micro SD up to 512 GB, FTP/SFTP, NAS). The camera is designed for outdoor use with IP66 and IK08 protection and wide operating temperature range.

Advantages

This model provides up to 4 MP resolution with a 2.8–12 mm motorized lens (4× optical zoom) and 16× digital zoom, enabling detailed monitoring at varying distances. Low‑light performance is supported by 0.005 lux (color) and 0.0005 lux (B/W) sensitivity plus IR illumination up to 20 m. Built‑in PTZ control (pan 0°–355°, tilt 5°–90°) with up to 300 presets, tour functions and power‑off memory facilitates automated coverage. The camera includes intelligent analytics such as perimeter IVS, face detection, people counting and SMD to reduce false alarms.

Suitable for

• Perimeter monitoring of commercial or residential properties
• Parking areas and driveways
• Entrances, gates and access control points
• Retail or public spaces requiring people counting and queue management

How to use

Install the camera in a location with a clear field of view and mount it according to the manufacturer’s instructions. Connect power (12 VDC) and network via Ethernet or configure the 2.4 GHz Wi‑Fi network. Configure video streams, compression (H.265 recommended for storage efficiency) and recording destinations (Micro SD/FTP/NAS) through the camera web interface or the DMSS/DSS Pro management software. Use PTZ controls to set presets and tours; enable analytics such as IVS, face detection or people counting as needed for monitoring and alerts.

Recommendations

For reliable outdoor performance, mount the camera under shelter when possible, keep the lens and IR windows clean, use H.265 to minimize bandwidth and storage, and periodically verify presets, tours and recording settings. Ensure the camera firmware is kept up to date and use secure passwords and HTTPS/ONVIF credentials to protect network access.
