RoboK

What it does

RoboK sells SiteLens, software that applies computer vision to video from a site's existing CCTV cameras ^[1][2]. RoboK says SiteLens identifies unsafe pedestrian-vehicle interactions, PPE violations (hard hats, high-visibility clothing and safety footwear), exclusion zone breaches, near misses and operational anomalies, and presents the results in safety dashboards with trend analysis ^[2]. A 2023 trade article described the product as focused on video clips and analysis of frequent low-level incidents, used for review and coaching, rather than on real-time alerts for every event ^[8]. Through a UK government funded project, the company has also been working on operational uses such as dwell time and workflow analysis alongside safety ^[9].

Who it is for

RoboK lists ports and maritime, logistics, warehousing, manufacturing, construction and critical national infrastructure as target sectors, with a focus on UK sites ^[2][3]. It was incorporated in Cambridge in September 2017 and spun out of the University of Cambridge ^[4][5]. Companies House lists Hao Zheng, Chao Gao and Liangchuan Gu as its first directors, and Cambridge Enterprise names all three as co-founders ^[4][5]. Hao Zheng is the chief executive ^[7].

How it is deployed

RoboK says SiteLens connects to existing CCTV without new cameras or hardware, and that it can install cameras for sites that have none ^[2]. The company quotes one to two weeks from first conversation to live deployment ^[2]. It says data stays in the UK, that it holds Cyber Essentials certification and that it is GDPR compliant ^[2][3]. The 2023 trade article reported that video streams were processed in batches by neural networks in the cloud ^[8]. Buyers should confirm whether that is still the architecture, since cloud processing affects bandwidth, retention and data protection reviews.

Notable public customers and coverage

In June 2023 RoboK announced $2.1 million in growth and grant funding, led by Cambridge Enterprise, bringing its total raised to $4 million ^[6]. UKTN reported the round as £1.7 million and listed investors including The Bristol Port Company, u-blox, Amadeus Capital Partners, Martlet Capital, Parkwalk Advisors and Deeptech Labs, plus grants from Innovate UK and the Department for Transport ^[7]. UKTN also named Bristol Port Company, Network Rail, National Highways and Transport for Wales as users ^[7]. RoboK and Cambridge Enterprise say Bristol Port saw a reduction of more than 90% in potential safety breaches within three months; this figure comes from the vendor and an investor and has not been independently verified ^[5][6]. Bristol Port is also a RoboK investor ^[7]. In January 2025 RoboK was named lead of PALLETS, a £1 million UKRI project for UK ports and warehouses, with partners including Port of Dover, Freeport East, The Bristol Port Company and the University of Essex ^[9][10].

Things to ask in an evaluation

• Which detections run in near real time, and which are reviewed later as clips and reports?
• Where is video processed today (on site or in the cloud), and what bandwidth does each camera need?
• How was the Bristol Port "potential safety breach" figure defined and measured, and was the baseline independently checked?
• Is a customer that is also an investor representative of the results you should expect?
• What face or body redaction options exist, and how long are clips retained?
• What support capacity does the company have outside the UK if you operate multiple countries?
