Common issues with IR Dome Cameras
This is a demonstration of issues you might find with IR Dome Cameras.
- If you noticed in this snapshot, you will see white spots around the image. This is caused when the lens is pointed straight up almost at 90 degrees. The lights are OFF and the IR’s are to close to the edge of the vandal dome housing. The light from the IR’s are bouncing back producing this issue.

Having problems with night time vandalism or theft? Perhaps you should consider an IR (InfraRed) vandal proof dome camera. These cameras can “see” where humans can’t and are made to be tamper resistant as well.
The camera is probably the most visible component of a digital video security and surveillance system. In addition, the camera is often placed right in the “heart” of the vandal inflicted area. This makes these cameras all the more incredibly obvious–and the target of even more vandalism.

What exactly is a 640 x 480 infrared camera? This can be a complicated answer for many reasons. In the following article we will attempt to address some of the characteristics that can make this seemingly simple question so complicated. Specifically, we will briefly discuss infrared technology and the reference to display resolution and how they relate to a 640 x 480 infrared camera.
First lets discuss the meaning of “infrared” when we talk about a 640 x 480 infrared camera. The term “infrared” refers to the wavelength of electromagnetic radiation. The wavelength of infrared radiation generally ranges between 0.7 and 300 micrometers abbreviated as “µm.” The exact range and categories defined may vary slightly depending on the scale that is used to describe the radiation.
