| + | Technically yes, but it's rarely practical, since guidance tasks usually need a wider field of view and different calibration than tight-tolerance inspection. Most integrators use dedicated cameras for each function to keep calibration and software logic simpler to maintain. | ||
| + | |||
| + | Industry surveys of automation deployments consistently show that inspection errors traced back to software misconfiguration or poor lens-camera matching account for a disproportionate share of unplanned downtime - some integrators estimate this figure at nearly a third of all vision-related service calls. That statistic alone explains why manufacturing engineers now treat software selection as a hardware-adjacent decision rather than an afterthought. Choosing among the available machine vision software solutions has become as consequential as selecting the sensor or lens itself, because the software layer determines whether a camera' | ||

| + | What Actually Determines Reliability in a Machine Vision System? Reliability in industrial imaging is rarely about peak performance under laboratory conditions. It is about consistent performance across a temperature range of perhaps 5°C to 45°C, in the presence of vibration from adjacent conveyors, and under lighting conditions that drift as ambient sunlight changes through the day. A machine vision system that performs perfectly in a demo booth can fail within weeks on a stamping line if its housing lacks adequate IP-rated sealing or if its sensor cannot maintain consistent exposure timing when triggered at variable line speeds. | ||

| + | The most common causes are ambient lighting changes across shifts, gradual lens fouling from airborne particulate, | ||
| + | |||
| + | The most common causes are vibration loosening unlocked focus or iris rings, and thermal expansion shifting internal lens elements or the housing itself. Industrial-grade lenses address this with locking mechanisms and athermalized designs, so specifying these features upfront reduces unplanned recalibration. | ||
