Light is a critical component in security management and surveillance imaging. With rapid advances in image sensors and LED lighting, today’s security surveillance cameras have much better performance in low-light, low-lux conditions, but real-life results still vary greatly from vendor to vendor. asmag has put together this special feature to help you look beyond lux ratings and decide what IR or thermal cameras to buy.
The migration to IP surveillance is driven by megapixel cameras. However, low-light performance remains an unknown, as smaller and less light-sensitive pixels are crowded onto an image sensor. a&s finds out whether megapixel ...
