Infrared Security Cameras : Great Choice for Daytime and Nighttime Video Surveillance
Our Infrared outdoor security cameras
provide a full color picture in daytime or adequate light situations and
gradually switch to BW in low light situations to maintain picture
quality. This is why they are sometimes referred to as Day/Night
cameras. Infrared cameras as their name suggest contain an array of
infrared LED's that turn on in low light and can provide a B/W picture
in complete darkness. They make great outdoor security cameras but can
also be used indoors. We carry a wide range of infrared surveillance
cameras from standard resolution fixed lens to HD (high definition) indoor and outdoor cameras along with infrared dome cameras. If you need help deciding on which cameras is right for your situation please feel free to contact us by phone or email.

Tips for Choosing the Right Infrared Security Cameras
When shopping for IR security cameras or night vision cameras as they are sometime called things you want to consider are the resolution of the camera sensor, size of lens (e.g. 6mm, 8mm) provided and the infrared distance. Obviously the higher the resolution of the camera the better the image quality but that should not be your only consideration. The size of the lens will determine your field of view or viewing angle. While the number and size of the LEDs along with the lens will determine how far you can see in complete darkness.
IR (infrared) distance ratings are the maximum distance an object can be illuminated, but as with any light source the closer you get to its maximum range the less light will reach the object. So if you want to be able to see someone 50 feet away you'll be better off selecting a camera with a rating 65 feet or more.
Not all outdoor security cameras are equal when it comes to weatherproofing. The IP Code (or International Protection Rating) is a rating of how well a device is protected from the elements. Not all cameras state their IP rating but IP65 is considered good for most outdoor weather conditions. If your camera will be exposed to some severe weather conditions you should probably choose a camera with an IP66 rating or higher.
Generally for nearby surveillance of 20 feet to 30 feet a 3.6mm to 4.3mm lens is good. This will give you a wide view of the area and facial recognition out to about 25 feet. This doesn't mean you can't see people or objects much further away they'll just appear smaller and harder to see clearly. If you need to see facial detail at a further distance of 35 to 50 feet away you would probably want to go with a 6mm or 8mm lens. Some surveillance cameras are equipped with a vari-focal lens which allows you to manually increase or decrease the lens size to suit your need. Keep in mind that the larger the lens size for any given distance the more detail you will see but your field of view will be smaller.
