SUMMARY
Canon has introduced its second camera, the MS-510 surveillance model, which features a 'single photon avalanche diode' (SPAD) sensor. This sensor technology is fundamentally different from the CMOS sensors commonly found in consumer cameras. While Canon is developing this advanced SPAD technology, it remains uncertain if or when it will be implemented in their broader range of cameras available to photographers.
TAKEAWAYS
Canon's MS-510 surveillance camera uses a SPAD sensor.
SPAD sensor technology differs from standard CMOS sensors.
It is unclear if SPAD sensors will be adopted for consumer cameras.
