You may need to adjust light sensitivity, white balance, and various settings to get the best picture possible. Outside cameras must be weatherproof and protected from wind, dust, rain, snow, and extreme temperatures. Surveillance cameras must have a stable power supply. Check that they have access to a constant power source and protect the power cords from damage cutting. Check your border surveillance cameras regularly to ensure they are working optimally. Clean the lenses; the objective of the cameras is to avoid the accumulation of dust and dirt that can alter the quality of the image.
