Branch inventory reconstruction

Accumulating holders Branches that accumulated shares during the window and still hold positive inventory; they are the absorbing side.

Distributing sellers Branches that built inventory earlier and have been selling it down; the remaining number estimates what has not cleared.

Net-short desks Trading-desk branches with negative inventory or net selling, often hedge, offsetting, or short-term flow. It is not automatically a bearish view.

Outlook 2025–2028

2025-2028 展望可分為成長動能與風險。成長動能：一、全球安控市場受美國 NDAA、歐洲資安與隱私規範、中國製安控設備替代需求推動，非中國製、台灣製、具資安合規的安控設備需求可望延續；勝品年報引用市場資料指出全球影像監控市場由 2024 年約 650 億美元成長至 2028 年約 920 億美元，CAGR 約 9.8%，但該數字為公司年報引用市場資料，非本研究獨立驗證。二、產品升級：公司持續開發 AI 結合深度學習之網路影像分析 NVR、人潮/物件/車牌辨識攝影機、特殊領域大型 PTZ 雙頻段成像攝影機、多感測器 Lidar+Camera、熱成像 AI 分析系統、AI Edge Computing、5G 無線監控、AIoT 搭配 5G 監控攝影機、8M 以上高畫素小體積高倍率鏡頭模組、多鏡頭環景成像拼接、SoM 上 AI 影像品質提升。三、市場拓展：公司短期重點為增加 NDAA 與 TAA 產品供應量，擴充北美 IP Camera、NVR 產品線，開發北美與歐洲 Tier 2/Tier 3 品牌、SI 系統整合商、AV 影音設備商，並以 ODM+中性品雙軌策略爭取較高附加價值業務。四、製造效率：導入 AI 影像檢測、智能料架、點料機、智慧排程、智慧工廠與戰情室看板，以提升良率、交期與成本競爭力。五、軟硬整合：公司由硬體供應商轉向完整解決方案，與 VMS 夥伴合作，提供遠端管理、AI 分析、開放 API、門禁 Access Control 整合與 Plug & Play 方案，尤其針對 SMB 缺乏內部系統整合能力的痛點。風險與挑戰：一、2025 年受美國關稅政策、新台幣升值、北美客戶拉貨節奏與庫存調整影響，營收與獲利波動；公司 2025/09 法說會對 2025Q4 與 2026 維持審慎樂觀，但仍須觀察關稅政策。二、客戶集中度高，2024 年前兩大客戶合計約 52.00%，訂單節奏變化會放大營收波動。三、外銷與美元計價比重高，匯率對損益有一定影響；公司 2024 年匯兌利益占營收 1.27%。四、中國安控品牌轉向價格競爭、國際 SI 併購整合改變採購策略，可能壓縮訂單與價格。五、AI 影像、資安、ESG、GDPR、NDAA 等法規及技術要求提升，研發、驗證、供應鏈管理與低碳製造成本增加。六、感光元件、影像處理 IC、光學鏡頭、記憶體、機構件等關鍵零組件供應與價格波動仍是營運風險。

Excess return is measured against the TAIEX total-return index (dividends included).
Valuation regime and percentile stats use an expanding own-history window (no future data).
Revenue-signal event dates align to the first trading day after the filing deadline, avoiding look-ahead.
Event samples may overlap in time; stats describe historical distribution only and are less reliable when samples are few.
