Dahua SD49225XA-HNR 2MP 25X Starlight Network PTZ Camera

The Dahua SD49225XA-HNR is a 2MP network PTZ camera built to cover large areas with a single device. Its 25X optical zoom lets you move from a wide overview to a tight, detailed view without losing image quality, so you can follow activity across a yard, parking lot, warehouse or street.

If you are comparing a Dahua PTZ camera for day and night surveillance, this model combines a 1/2.8" STARVIS CMOS sensor, Starlight low-light performance and a 100 m IR illumination distance. That makes it a practical choice for businesses, factories and properties that need reliable monitoring after dark.

Key Features

• 25X optical zoom (4.8 mm to 120 mm lens): Zoom in on distant people, vehicles or objects while keeping the picture clear, so one camera covers more ground.

• 2MP Full HD resolution (1920 x 1080): Delivers sharp, detailed 1080p video that helps you identify what is happening in the scene.

• 1/2.8" STARVIS CMOS sensor: Captures more light for cleaner images in dim conditions, which is useful for evening and early-morning monitoring.

• Starlight low-light performance: Minimum illumination of 0.005 Lux in color mode and 0.0005 Lux in black and white mode at F1.6, so scenes stay visible with very little light.

• IR illumination up to 100 m (328 ft): Six IR illuminators provide full darkness coverage (0 Lux with IR on), keeping distant areas visible at night.

• Flexible illuminator control (Zoom Prio / Manual / SmartIR): Choose how the IR lights behave to reduce overexposure and get balanced night images.

• Wide field of view with deep zoom: Horizontal view from 62.8 degrees down to 2.6 degrees lets you survey a broad area and then focus on small details.

• Fast electronic shutter (1/1 s to 1/30,000 s): Helps capture moving subjects with less blur across different lighting conditions.

• WizSense technology: Part of Dahua's WizSense line for intelligent, network-based video surveillance.

Why Choose This Network PTZ Camera

A fixed camera sees one angle. This Network PTZ Camera can pan, tilt and zoom, so a single unit can monitor an area that would otherwise need several cameras. That can simplify installation and make it easier to check on exactly what you need.

The Starlight sensor and 100 m IR range support round-the-clock monitoring, while the 25X optical zoom gives you detail at a distance. For anyone searching for a dependable Dahua PTZ camera in Bangladesh, the SD49225XA-HNR offers a balance of zoom range, night performance and Full HD clarity.
