功能：
警报器和光主动威慑：大华警报器和光主动威慑网络摄像机支持周界事件发生时光报警和语音报警，实现威慑和有效干预。摄像机内置多种语音可供选择，支持自定义语音导入。
智能双照明器：大华智能双照明器技术采用智能算法来检测目标。通常，红外照明器在夜间打开；当目标出现在监控区域时，暖光灯亮，摄像机记录全彩视频和关键事件信息。也就是说，相机将快照和视频与全彩图像链接起来。当目标离开监控区域时，暖光关闭，红外照明器开启，有效减少光污染。
SMD：大华智能移动检测技术通过智能算法，对触发移动检测的目标进行分类，过滤掉非关注目标触发的移动检测报警，实现有效、准确的报警。
一键撤防：大华一键撤防功能，方便易操作，是事件联动的开关。客户可以通过手机App关闭和恢复事件联动，满足多场景需求。
网络安全：大华网络摄像机采用了一系列安全技术，包括安全认证与授权、访问控制协议、可信保护、加密传输、加密存储等。这些技术提高了相机对外部网络威胁的防御能力，并防止恶意程序损害设备。
防护等级（IP67、宽电压） IP67：摄像机通过了一系列严格的防尘、浸泡测试。具有防尘功能，外壳在1m深的水中浸泡30分钟即可正常工作。宽电压：摄像机允许±30%的输入电压容差（宽电压范围），广泛应用于电压不稳定的户外环境。
TiOC 2.0
What is TiOC 2.0?
With its foundation from the previous generation of TiOC, a variety of new innovative technologies are introduced in the latest TiOC 2.0 for the first time, achieving breakthroughs and quality improvements in illuminators, audio and images. At the same time, TiOC 2.0 can be integrated with alarm system through software upgrades. It provides better ecosystem that offers more convenient operation and better user experience.
Smart Dual Light
• Smart Illumination Mode (Default): Switch between IR Mode and warm light when target is detected.
• IR Mode (Optional): Only the IR illuminator is ON. It is suitable for scenes where supplementary warm light is not required, significantly reducing light pollution.
• Warm Light Mode (Optional): Only the warm light is ON. It is suitable for scenes that require color video footages.
VoiceCatcher Technology
• Newly-designed Dual Mic Array intercepts external circuit interference.
• Audio pick-up distance is increased by 7 meters compared with the previous version of TiOC in a lab environment.
• The Dahua VoiceCatcher reduces noise and extracts audible audio signals.
Better Image
• First Dahua camera powered by OPC (Optical Path Technology). It corrects the refraction angle of different light path. With F1.0 large aperture lens, it outputs brighter and clearer black & white images.
• 4K Real-time: Smooth 4K real-time images at 30 fps even when AI is enabled, with high brightness using F1.0 large aperture.
Easy Operation
• Alarm-in Port: Allows alarm receiving or one-tap disarming through the alarm system interface.
• One-tap Disarming: Turns on/off the warning light and siren via the DMSS or alarm-in port.
• Alarm Sounds: Offers 11 built-in sounds and supports importing of custom voice audio for different scenarios.
AI Features
SMD 4.0: Reduces false alarms caused by animals
With upgraded AI capabilities, the SMD function filters out irrelevant objects in the scene. Equipped with new deep learning algorithm, SMD 4.0 is optimized to filter out small and large animals in the scene to avoid triggering false alarms.
Perimeter Protection
The perimeter protection function based on tripwire and area intrusion sends an alarm only when unwanted movements triggered by human or vehicle targets occur, saving users from unnecessary actions caused by false alarms.
AI SSA
With the continuous development of video surveillance and AI, the demand for images with higher quality is also increasing.
The Dahua AI SSA (Scene Self-adaption) technology is based on deep learning algorithm that can intelligently identify multiple scenes and adjust to their optimal images.
Auto Tracking 3.0 (PTZ)
Smooth Tracking Process
Combined with PFA 3.0 algorithm (a deep fusion of intelligent algorithms and focusing algorithms), it realizes touchless focusing during the tracking and capturing process.
Long Tracking Distance
With the Automatic Tracking 2.0 algorithm as its foundation, the requirements on the tracking size of the target are further reduced, making the target size smaller and the tracking distance longer. The tracking distance of Automatic Tracking 3.0 can reach up to 870 meters.
Applications
Private Places
• Less Light Pollution: Less use of white light means less light pollution
• Active Deterrence: Warn off intruders during the intrusion
• Color Monitoring: Presents color alarm videos
• Scenarios: Villas, shops, warehouses, etc.
Public Areas
• Active Deterrence: Customized sounds and light alarm to warn the target in the area
• Accurate Detection: Focuses on human and vehicle targets to accurately identify real targets
• Ecosystem: One-tap disarming with alarm-in port or DMSS.
• Scenarios: Fire exits, emergency exits, etc.
