Company profile

Longse Technology Limited (Chinese: 长视科技股份有限公司; also rendered Guangzhou Longse Technology Co., Ltd., brand "Longse") is a privately held Chinese manufacturer of video-surveillance equipment, founded in April 2006 and headquartered in Guangzhou, Guangdong (No. 18 Dongming 3rd Road, Huangpu District; earlier addresses on Kaichuang Avenue). It is not publicly listed. Size figures vary by source: Longse's own website claims 600+ employees worldwide, Baidu Baike cites 1,200+ staff for its Guangzhou Longse Electronics subsidiary, and third-party data providers (Crustdata) list roughly 260; a revenue band of $50–100M appears only in a third-party estimate (Adapt.io) and could not be confirmed from company filings.

Products / operations. Longse is an operating company, not a shell licensor. Its own materials describe an IoT/video business integrating R&D, manufacturing, sales and service, with OEM/ODM and custom-solutions divisions and its own factory park. Product lines include IP/network cameras, HD analog (AHD/TVI/CVI) cameras, 4G and Wi-Fi solar-powered battery cameras, PTZ and dual-lens cameras, NVR/XVR recorders, smart hubs, and VMS/mobile apps (SV360, BitVision, ACESEE). It distributes in roughly 130+ countries via OEM/ODM and channel partners.

Litigation posture. Longse appears in the tracked data only as a defendant (0 plaintiff cases, 1 defendant case), consistent with an operating manufacturer targeted by a non-practicing entity rather than an active two-way litigant.

Notable case. Cedar Lane Technologies Inc. v. Longse Technology Limited, No. 6:22-cv-00655, filed June 23, 2022 in the U.S. District Court for the Western District of Texas (Waco Division) before Judge Alan D. Albright — a plaintiff-friendly patent venue. Cedar Lane is a Canadian NPE founded in 2019 that acquired patents originating with Intellectual Ventures and has filed hundreds of suits, largely in W.D. Tex.; the asserted patents include US 6,972,790 ("Host interface for imaging arrays") and US 6,473,527. Cedar Lane voluntarily dismissed the case without prejudice on October 24, 2022.
