Sony 61MP Surveillance Sensor Examined
For a decade, the highest resolution single-imager surveillance cameras have remained ~30MP, now Sony has released a 61 MP sensor (IMX455AQK-K) marketed to surveillance.
While Sony exited the branded video surveillance business this year, they continue in sensors.
IPVM explores how this sensor has been used and what it means for surveillance cameras.
