Product information

Description

DAHUA SD8A840-HNF-PA is an IP security camera designed for high-detail surveillance with a 3840×2160 resolution and a 1/1.8" CMOS sensor. The unit supports both indoor and outdoor ceiling mounting and provides long-range observation with 40x optical zoom and 16x digital zoom. Built for wired Ethernet connectivity and PTZ control, this camera offers 30 fps real-time capture, night vision and wide dynamic range for reliable performance in varied lighting conditions.

Advantages

The camera delivers high-resolution 4MP imaging combined with powerful optical zoom to capture distant details while maintaining image clarity. PTZ control with full 0–360° pan range allows flexible area coverage and precise tracking. Weather-resistant design meets IP67 rating for outdoor use and the camera supports day/night operation, noise reduction and WDR to handle backlit or high-contrast scenes. Built-in microphone, alarm input/output and integrated card reader expand integration and on-site recording options.

Suitable for

  • Perimeter and long-range perimeter surveillance
  • Building entrances, parking lots and large outdoor spaces
  • Indoor atriums, warehouses and public halls requiring ceiling-mounted PTZ coverage
  • Situations requiring combined zoom, audio monitoring and alarm integration

  • Resolution: 3840 × 2160 (4 MP)
  • Sensor: 1/1.8" CMOS
  • Frame rate: up to 30 fps
  • Pan range: 0–360° with PTZ control
  • Day/night mode with infrared night vision; night vision range up to 500 m
  • Wide Dynamic Range (WDR) and noise reduction
  • Connectivity: wired Ethernet LAN; power: DC
  • Ingress protection: IP67 for outdoor resistance
  • Built-in microphone and alarm input/output; integrated card reader
  • Mounting type: ceiling; placement: indoor and outdoor
  • Weight: 10 kg; colours: black and white

How to use

Mount the camera on a suitable ceiling mount rated for the device weight and environmental conditions. Connect the camera to a stable DC power source and wired Ethernet network to enable video streaming and PTZ control. Configure basic settings such as resolution, frame rate and WDR through the camera's web interface or supported VMS; set up night mode and IR parameters for low-light coverage. Use PTZ presets and patrols to automate area sweeps and integrate alarm inputs/outputs for event-triggered recording or notifications.

Usage recommendations

For optimal long-range performance, perform periodic focus and optical alignment checks, ensure the mounting point provides clear sightlines, and configure appropriate bitrate and storage settings on your recorder to retain high-resolution footage. In outdoor installations, verify cable glands and seals remain intact to preserve IP67 protection.

Focal length range: Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).

Image sensor

Progressive scan: Also referred to as noninterlaced scanning, this is a way of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately.Progressive scan is used for DVDs and HDTV (high defintion television).

Optical sensor size: Optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications e.g. lamps that turn on automatically in response to darkness. Optical sensors come in many sizes.

Design

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
