- Weather resistance – IP66 class – complete protection against dust and heavy objects, rain.

1. Excellent image quality in any conditions
- Thanks to 1/1.8 inch 4MP STARVIS™ CMOS sensor, the camera provides clear, colorful images even in minimal lighting (0.0005 lux!).
- Supports WizColor technology, guarantees natural color reproduction around the clock.
- Support 4MP for resolution with smooth 30 frames/sec. allows you to see every detail.
2. Artificial Intelligence Based Intelligence System – SMD 3.0 and Automatic Tracking
- SMD 3.0 technology prevents false alarms by distinguishing people and vehicles from inappropriate movements in the environment.
- Function Car Tracking Lite allows the camera to automatically track intruders in its field of view, providing complete control over the situation.
- In addition, perimeter protection (Perimeter Protection) allows you to precisely define security zones.
3. Active deterrence – light and sound
- Built-in warm lights and sounds Alerts (16 predefined alarms + the ability to add your own) act preventively, deterring potential intruders before they take action.
- The ability to adjust the timing and intensity of warning signals increases the effectiveness of protection.
4. PTZ functions in a compact body
- Panning 0°–345° and Tilt 0°–90° allows flexible monitoring of large areas.
- Up to 300 preset settings and patrol routes provide automatic scanning of the area without the need for constant operator intervention.
5. Support for modern standards and easy integration
- Compatibility with ONVIF protocols, PoE support, a microSD card slot, and a wide range of network protocols make the camera perfectly integrated into existing infrastructure.
- Cooperation with DSS Pro software, NVR recorders and mobile apps (iOS / Android) provides complete control from anywhere.
6. Durability and reliability
- Sturdy construction with IP66 The protection class guarantees operation in difficult weather conditions - rain, snow or dust are not a problem.
- Surge resistance (TVS 2000V) ensures installation safety.
Why is the Dahua SD2C400NA-B-PV-PRO camera a unique solution for your surveillance?
Camera SD2C400NA-B-PV-PRO is a modern device that combines advanced technology, intelligent functions and solid construction. It is a great choice for people and businesses that expect reliability, accuracy and intelligent protection in any situation.
SMD 3.0 technology (Smart Motion Detection 3.0)
SMD 3.0 is an advanced intelligent motion detection technology developed by Dahua, which greatly improves the efficiency and accuracy of surveillance systems.
Unlike traditional motion detection, which responds to any movement in the camera's field of view (e.g. moving branches, animals, rain), SMD 3.0 uses artificial intelligence (AI) algorithms to determine object recognition and classification.

Two-way audio/talk and listen thanks to the built-in microphone and speaker!
Dahua SD2C400NA-B-PV-PRO IP camera provides improved two-way communication, allowing you to communicate from anywhere, anytime with just one click. Thanks to the built-in microphone and speaker, you can not only talk to people within the camera's range, but also hear sounds from the surrounding area. This is an ideal solution for monitoring your home, office or property, allowing you to immediately respond to disturbing events and stay in touch with loved ones or employees. The camera provides full audio interaction, which not only provides a sense of security, but also convenience in everyday use.
