Dahua Technology SDT4E425-4F-GB-A-PV1-S2 security camera IP security camera Indoor & outdoor 2560 x 1440 pixels Ceiling/Wall/Pole

Dahua SDT4E425-4F-GB-A-PV1-S2 is a wired IP security camera designed for both indoor and outdoor surveillance. It delivers 2.56 MP (2560×1440) resolution from a 1/2.8" CMOS sensor and provides up to 25× optical zoom. The camera supports 30 fps video, a wide horizontal field of view, long-range IR illumination and IP66-rated weather protection. Mounting options include ceiling, wall and pole installations to suit varied surveillance layouts.

Advantages

The camera combines a high-resolution 4 MP sensor with a 25× optical zoom to capture detailed images at distance while preserving image quality. With a minimum illumination down to 0.001 lx and 100 m IR capability, it supports low-light and night monitoring. Wired Ethernet connectivity ensures stable network transmission, and IP66 protection allows reliable outdoor operation in inclement weather. Built-in intelligent features such as video motion detection, auto tracking and perimeter protection streamline event detection and reduce manual monitoring.

Suitable for

• Perimeter and entrance monitoring at commercial or industrial sites
• Parking lot and roadway surveillance requiring long-range zoom and night vision
• Large indoor areas such as warehouses or shopping centers where pan/tilt/zoom coverage is needed
• Outdoor public spaces and facilities exposed to weather conditions

How to use

Install the camera on a suitable ceiling, wall or pole mount ensuring a clear line of sight for the intended coverage area. Connect the device to a PoE switch or provide power and wired Ethernet for network access. Use the Dahua-compatible recording system or VMS to configure resolution, frame rate and motion detection zones. Adjust optical zoom and focus through the camera’s PTZ controls to frame targets accurately. Verify IR function and low-light performance during night conditions and set up auto tracking and perimeter rules according to site requirements.

Recommendations

Position the camera high enough to maximize field of view while minimizing obstructions and tampering risk. For reliable long-range identification, combine optical zoom with appropriate scene lighting and ensure bitrate settings on the recorder match the chosen resolution and frame rate.
