800 萬像素超清畫質

清晰的影像品質是 HDW2841T-S 的一大特點。它最高輸出 8MP（3840×2160），能夠捕捉更多面孔、衣著同車輛細節，讓您更清楚地看到門口同周圍環境。配合 120 dB 寬動態，無論是日間逆光門口還是陰暗走廊，您都可以獲得更實用的畫面效果。

Clear 8MP Image Quality

Clear imaging is a major highlight of the HDW2841T-S. With up to 8MP (3840×2160) resolution, it captures finer detail on faces, clothing and vehicles. With 120 dB WDR, whether it is a backlit entrance by day or a dim corridor, you can enjoy more usable image quality.

人車智能偵測（SMD Plus）

除了清晰畫質同紅外夜視外，HDW2841T-S 還支援越線／入侵偵測，並可做人、車分類（SMD Plus），減少樹影、小動物等誤報。只要有可疑活動出現在您設定的區域，您就可以透過 NVR／客戶端更快收到通知。

Smarter Alerts with SMD Plus

Beyond clear imaging and IR night vision, the HDW2841T-S supports tripwire/intrusion detection with human and vehicle classification (SMD Plus), helping reduce false alarms from tree shadows or small animals.

PoE 單線供電

支援 IEEE 802.3af PoE，一條網線同時傳訊號同電源，外牆走線更簡潔；亦可用 12 VDC。配合本公司 Dahua／相容 PoE NVR，即可「訊號與電源 all in one」，裝機同日常監看出入口都更方便。

PoE Single-Cable Power

With IEEE 802.3af PoE, one network cable carries both video and power for neater outdoor wiring; 12 VDC is also supported. Pair it with a compatible PoE NVR for a simple all-in-one signal-and-power setup.

內置咪高風收音

鏡頭內置收音，配合支援音訊嘅 NVR／客戶端，可一併記錄現場聲音，適合門口、舖面等需要聲音參考嘅場景，令監控資訊更完整。

Built-in Microphone

A built-in microphone records on-site audio when used with an audio-capable NVR or client—useful at doorways and shopfronts where sound provides extra context.

IP67 室外防護

機身達 IP67 防水防塵等級，適合香港室外日曬雨淋環境，裝喺外牆、車路同村屋門口更放心。

IP67 Weather Protection

IP67 dust and water resistance suits Hong Kong outdoor sun-and-rain conditions, giving more confidence for exterior walls, driveways and village-house entrances.
