What cameras should I use?

Camera specifications vary depending on what one wants to see, the precision, the distance, the angle, picture sharpness at night, visibility, whether it is indoor or outdoor, and more. These factors all need to be considered before a camera is chosen. The camera lens will specify distance, angle and clarity, and the lenses can also be set to have a variable focus. Infrared LEDs are used to allow a clear picture in low light or at night. If a camera is facing a window on which direct sunlight will fall, a camera with a wide dynamic range function is needed. The difference between domes and pipe cameras is usually just aesthetical, unlike the general perception that domes can cover a 360ยบ angle. These points show that choosing the right camera is not a straightforward task, and that a site visit is normally required.
