Perimeter Protection

• Utilize Dahua Analytics+ features like Tripwire and Intrusion functions for custom tripwires and improved object detection accuracy in limited access areas.

Smart Motion Detection

• Enhance alarm accuracy with Smart Motion Detection that filters out non-human or non-vehicle motion, reducing false alarms.

Flexible Recording

• The NVR offers configurable recording options based on motion detection, alarms, schedules, and intervals, optimizing disk space and monitoring time.

Smart H.265+ and Smart H.264+

• Optimize video compression with Smart H.265+ and Smart H.264+ technologies that reduce bandwidth and storage requirements by up to 70% compared to standard codecs.

FAQ:

Q: How do I set up motion detection on the cameras?

• A: You can configure motion detection settings through the camera’s interface or the NVR’s software. Refer to the user manual for detailed instructions.

Q: Can I view live footage remotely on my smartphone?

• A: Yes, you can remotely access live video feeds from the cameras and doorbell using the dedicated mobile app provided by Dahua.

System Overview

• The Dahua Video Doorbell Network Security System provides all the components to quickly install, configure, and employ a complete video security solution.
• The WiFi video doorbell offers 5MP video and two-way communication, the IP camera offers the clarity of 4MP video, and the NVR offers built-in motion detection algorithms, alarm triggers, and customized recording modes.
• The doorbell and network cameras connect easily to the NVR for total system recording.
• In addition, the Video Doorbell and the NVR are compatible with the Dahua DMSS mobile application to view live video, configure and acknowledge alarms, and share video with authorized users.

Functions

Basic Night Color (VU-MORE Color) Technology

• Dahua’s Basic Night Color (VU-MORE Color) cameras offer multiple features such as motion detection and Smart Dual Illumination to provide deterrence, overtness, and full-color video in low-light scenes.
• These cameras are designed to reduce light pollution by only turning on the white-light LEDs for full-color images when human motion is detected.

Smart Dual Illumination

• The camera offers both IR and white-light illuminators and intelligently employs each depending on the situation. The camera enters the IR mode as ambient light decreases.
• When the camera detects an object entering the monitoring area, it activates the white-light illuminator to capture full-color details. Once the object leaves the area, the camera switches back to IR illumination.

WiFi Doorbell

• The 5MP WiFi Video Doorbell is a component of the Dahua LincX2PRO residential series.
• The doorbell offers specialized motion detection that distinguishes humans from other objects and transmits video and audio to a mobile device for remote visual confirmation and communication with visitors.

Perimeter Protection

• Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas.
• Perimeter Protection requires less pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals.

4MP Network Cameras

4K Network Video Recorder

• 2 TB Pre-installed Hard Disk Drive
• Supports Remote Configuration and Management of Network Cameras
• Smart H.265+ and Smart H.264+ Dual Codec
• Maximum 80 Mbps Recording Bandwidth

Smart Motion Detection+

• Smart Motion Detection, a component of Dahua’s Analytics+ technology, improves alarm accuracy and decreases the number of false alarms.
• The advanced SMD algorithm analyzes a scene for human or vehicle motion, while filtering out other motion due to trees, leaves, animals, and weather, and triggers an alarm when detected.

Flexible Recording

• The NVR offers a variety of configurable recording options and schedules that save disk space and active monitoring time. The NVR monitors incoming video and can be programmed to record if motion is detected or if an alarm is triggered.
• The NVR can also be programmed to record on a schedule or at different intervals. The recording options and schedules can be set for each camera or copied to all cameras.

Smart H.265+ and Smart H.264+

• Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure, and intelligent noise reduction to deliver high-quality video without straining the network. Smart H.265+ technology reduces bit rate and storage requirements by up to 70% when compared to standard H.265 video compression.
• Delivering high-quality video without straining the network, Smart H.264+ is the optimized implementation of H.264.
• The Smart H.264+ encoding platform includes a scene adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure, and intelligent noise reduction, providing savings of up to 70% of bandwidth and storage when compared with standard H.264.

Environmental

• With a temperature range of –40° C to +60° C (–40° F to +140° F), the cameras are designed for extreme temperature environments.
• The cameras, subjected to rigorous dust and water immersion tests, are certified to the IP67 rating making them suitable for demanding outdoor applications.
• The NVR features an operating temperature of -10° C to +55° C (+14° F to +131° F).

NVR Dimensions

1. The DORI distance is a measure of the general proximity for a specific classification to help pinpoint the right camera for your needs. The DORI distance is calculated based on sensor specifications and lab test results according to EN 62676-4 , the standard that defines the criteria for the Detect, Observe, Recognize, and Identify classifications
2. Pair a Smart Motion Detection camera with a Dahua recording device that also offers SMD functionality to take advantage of SMD alarm filtering and object classification when searching and playing back recorded video.
3. Do not supply power to the DH-DB6I via the USB port. Use only the Power Input Ports, as detailed in the Quick Installation Guide, to supply power to the device.
4. The recorder’s Analytics+ functions are available only when connected to a Dahua network camera with Analytics+ functionality.
5. Do not supply power to the DH-DB6I via the USB port. Use only the Power Input Ports, as detailed in the Quick Installation Guide, to supply power to the device.
