You obviously don’t have to worry about weather-proof cameras if you only intend to use the cameras for indoor surveillance. But, if you are more concerned about what goes on in your garage, front and backyard, you will need a weather-proof camera so you can rest easy knowing that they will be functional in rain, heat, snow or sleet. Cameras that are nor rugged cannot be used for outdoor surveillance. A good outdoor camera should have a high Ingress Protection to resist damage from powerful jets of liquids, dust, and solids.
