Typically monochrome cameras are less expensive and perform better at little light than colour cameras. Colour cameras switch to black and white in low light conditions.
2) What type of night eyesight capability is needed? A typically packed colour security camera should have a night vision array of between 15 and 60 feet. High powered night eyesight cameras can have a range of one hundred and fifty feet.
The main factor involving determining the night vision selection is the number of infrared LEDs on the camera. Most standard purpose security cameras come with eighteen to 30 LEDs. Recall even colour cameras track black and white records in little light situations.
