Dahua IPC-HFW1431S1-A is a 4 MP bullet IP camera with a built-in microphone, a 2.8 mm lens, and IR illumination up to 30 meters. The extended dynamic range WDR 120 dB allows the camera to simultaneously correctly render dark and bright areas of the frame, while the built-in microphone adds audio recording without additional equipment. The model is created for outdoor installation where detailed video capture with sound recording is important.
Advantages
- 4 MP resolution — a clear and detailed frame for the identification of people and vehicles
- WDR 120 dB — the camera preserves details both in shadow and in bright light, for example at an entrance with glass doors
- Built-in microphone — audio recording without the need to install a separate microphone
- IR illumination up to 30 m — confident night surveillance at a distance of up to 30 meters
- 2.8 mm lens — a wide viewing angle covers spacious areas
- IP67 protection rating — resistance to rain, snow and dust for reliable outdoor operation
Applications
- Retail outlets and supermarkets — detailed recording of checkout areas with audio
- Entrance groups of office and administrative buildings — monitoring in any lighting thanks to WDR
- Residential complexes and entrances — surveillance of the entrance with capture of negotiations
- Banks and financial institutions — high resolution and audio recording for complete documentation of events
- Outdoor perimeters — night recording with 30 m IR illumination
Frequently asked questions
What does WDR provide when filming an entrance group?
In backlight (for example, light from the street through a glass door) an ordinary camera overexposes the background or loses face details. WDR 120 dB balances the exposure and preserves details across the entire frame simultaneously.
Is audio recorded synchronously with video?
Yes, the built-in microphone transmits sound in the same stream as the video — provided audio recording is supported by the DVR.
Can the camera be used without IR illumination?
The illumination can be disabled or scheduled to operate on a schedule via Dahua software.
