As more retail stores sell lower cost video surveillance cameras, the level of expertise given to the customer is waning leading to almost pointless protection. A lot of low cost surveillance cameras have integrated infrared (IR) lighting positioned in a ring surrounding the lens, which probably sounds like a great approach because these cameras can see at nighttime. In fact some have a specification of zero lux. While it is true that they will work in complete darkness (0 lux), what is actually not mentioned is at what range.
