Many bullet cameras are also known as lipstick cameras. Some only have a diameter of 3/4" Basically just a small slender surveillance camera. We have also included our professional box cameras and an underwater camera as well in this category. None of these cameras have infrared leds. That is another category. Some of these are weatherproof and some are not. They are best suited for well or decently lit areas. We do offer a .0003 lux bullet camera which is specifically advertised as such and can see very well in the dark, but still not as good as an IR LED camera. The .0003 lux is a very good choice when size and power consumption are an issue.
