System Overview

The Active Defense series of small PT cameras raises the bar on
performance. After detecting an intrusion, it triggers sound and light
alarms, and then instantly relays vital information on the intrusion to
the mobile client, keeping you informed no matter where you are. It
supports two-way talk, allowing you to communicate with people in
front of the camera in real time. It also records videos in full color, and
uses Smart Dual Light to help produce vivid images, making it easy to
obtain information on events, and reduce light pollution.

Functions

Smart H.265+ & Smart H.264+
With advanced scene-adaptive rate control algorithm, Dahua smart
encoding technology realizes the higher encoding efficiency than H.265
and H.264, provides high-quality video, and reduces the cost of storage
and transmission.

Two-way Talk
With its built-in high-sensitivity microphone and high-power speaker, the
camera realizes two-way talk through the mobile app.

Smart Dual Light
Dahua Smart Dual Light technology adopts smart algorithm to detect
targets. Usually, the IR illuminator is on at night; when the target appears
in the monitoring area, the white light is on, and the camera records the
full-color video and information of key events. That is, the camera links
snapshot and video with full-color image. When the target is out of the
monitoring area, the white light is off and the IR illuminator is on, which
reduces light pollution efficiently

IVS
With advanced video algorithm, Dahua IVS technology supports
intelligent functions, such as tripwire and intrusion.
Siren and Light Active Deterrence
Dahua siren and light active deterrence network camera supports the
white light alarm and voice alarm when perimeter event occurs, to
realize the deterrence and effective intervention. The camera is built in
one voice, and supports customized voice importing
