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.

Business

京晨科為安全監控廠，核心業務是影像錄影與影像管理系統，產品與解決方案涵蓋 NVR 網路影像錄影機、DVR/混合式監控、VMS 影像管理平台、中央管理系統、NUUO Crystal、MainConsole、Titan Pro、網路攝影機與周邊配件。公司採自有品牌 NUUO 行銷全球，亦設 OEM 事業部，為國際品牌大廠進行監控軟體代工。商業模式同時包含軟體授權、硬體/嵌入式錄影設備、系統整合支援、維護服務與 OEM/ODM 類合作；產品多採委外加工生產。應用場景包括城市監控、大樓、工廠、運輸、校園、銀行、商店、機場、公共安全、POS交易影像整合、門禁、車牌辨識、人臉辨識、智慧影像分析與 Modbus/第三方系統整合。NUUO 官網揭露 Crystal 系列支援多站點集中管理、Linux系統、單錄影伺服器最高64支百萬畫素攝影機、最高256路/860Mbps、第三方 POS 與門禁 metadata 整合，並支援超過4,000款攝影機與130個以上品牌。營收結構方面，公司主要經營業務標示為數位監控系統；第三方資料列示電子零組件/硬體類約85.8%、提供勞務約6%、軟體產品約4.4%，但該比例未明確標示完整年度，僅作輔助參考。2025全年營收約新台幣4.982億元，較2024下滑；2026年1至5月累計營收約5.230億元，已超過2025全年，年增約135.89%，主要反映專案出貨與安全監控需求回升，但單月營收受專案交付節奏影響大。

Outlook 2025–2028

2025年：公開法說與市場整理資料指出，2025年前三季合併收入約3.5126億元，營運較前一年下滑，監控事業營收受客戶建廠計畫與工程進度影響，逐步回復穩定；公司同時透過降低管銷費用、改善毛利維持本業獲利。2025全年營收約4.982億元，年減約35.8%，顯示基期與專案波動壓力仍在。2026年：截至2026年5月，單月營收1.42572億元，月增12.28%、年增約368.79%，1至5月累計營收5.23039億元、年增約135.89%，已明顯優於2025同期與全年水準，短期動能來自安全監控專案出貨、AI監控題材、企業/公共場域監控升級與海外通路需求。不過此成長是否具延續性，須觀察毛利率、應收帳款、存貨、專案驗收與軟體收入占比。2027至2028年：產業面受惠於全球視訊監控、VMS、AI影像分析、雲端監控、邊緣運算、智慧城市、工廠/零售/交通安全需求成長；第三方研究普遍預估2025至2031年視訊監控市場仍有中高個位數至雙位數年複合成長，AI影像分析與VMS軟體成長率更高。京晨科若能把 NUUO VMS、IVS、人臉/車牌辨識、POS/門禁整合與 OEM 軟體代工轉為更高毛利、可重複授權或維護收入，2027至2028年有機會改善營收品質與評價彈性。主要風險包括公司規模小、單一/少數專案出貨波動、客戶與OEM訂單能見度有限、低價中國安控品牌競爭、AI功能商品化導致毛利壓力、資安與個資法規要求提高、海外通路與匯率風險、硬體零組件供應成本、以及公司近年金融資產評價利益對獲利波動的影響。

Method and limitations

  • All returns use adjusted close (etl:adj_close), already adjusted for dividends and splits.
  • 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.
