Types of Cameras

The different types of cameras are plentiful. Surveillance cameras come in a variety of shapes and sizes, each with their own advantages and disadvantages. When trying to determine which camera is best for your situation, the following aspects should be considered:

  • Distance from the camera to the desired field of view, or the actual location the camera is viewing/recording.
  • Width of the field of view you’re looking for
  • Lighting changes that occur, or low/high lighting requirements
  • Whether you need color or black and white (B&W works well in low lighting)

Buyers need to consider all of these factors when determining which camera is right for them, because there is simply not a camera that works with every individual circumstance. It is important to evaluate each individual location when deciding to purchase a camera system.
