respondents (47 per cent) already use video in data recording today, while 54 per cent of the respondents expect video use within their organisation to increase in the next year. The survey was conducted in autumn 2016 among 100 respondents fromEurope, though its emphasis was on the Nordic countries. “Based on the study, there is no longer any
question that recording video data in parallel to tactile sensors or digital bus signals is becoming more andmore attractive to users,” says Christof Salcher, productmanager instrumentation atHBM. “Video supports traditional sensor data and is becoming a valuable source of additional information,making the roomfor interpretation even narrower in testing. “As the tactile and non-tactile worlds of data
collection are coming together, it is not a question of using either video or traditional sensor data – but of both. Going forward, we will see sensors and video integrated together into data acquisition systems (DAQ) inmore application areas over time,” Salcher concludes. EE

ccording to a recent survey by test and measurement companyHBM, video use is accelerating in data collection. Video cameras are already used inmany test andmeasurement applications
Is your use of video in data collection expected to increase or decrease in the next year?
Increase Decrease Stay the same I don’t know 0% 10% 20% 30% SURVEY SUMMARY
Videomost commonly used in structural durability, fatigue testing (48 per cent).Machinemonitoring or general lab testing (30 per cent) and mobile data acquisition or road load data acquisition (28 per cent) also relatively common. Top reason for using video is to gain additional input analysing unexpected deviations (73 per cent). Also decision finding (50 per cent) and visualisation of results to management (41 per cent). Webcams themost common
equipment for video in data collection. Some 80 per cent of respondents use this type. High- speed video used bymore than one-third of respondents, often in combination with traditional video. Video in data collection likely to increase substantially, both by those already using video and by those who do not. Use bringsmore use – Those already using video aremore prone to increase their usage within the next year (76 per cent).
