8. Troubleshooting Before sending the camera out for repair, check the items below. If the problem persists after checking these items, contact your service center. Problems Trouble shooting Nothing appears on the screen. The video image is not clear. The screen is dark.  Please check the power connection.  Please check the video signal line connection.  Please check if the lens or the outer glass is clean. - Dirt or fingerprints on the lens can affect the image blooming or reflection. Gently wipe any dirt or fingerprints off the lens or the glass with a soft cloth.  Please check and adjust contrast feature of the monitor  Please check if the camera is exposed directly toward a bright light, sunlight, or sun light reflecting area. Please move the camera's position in this case.  This is normal, because of the optical filter that rejects visible light and the high-shutter speed. Mainly highly reflective objects within 31' range of the IR LED's will be visible. For most applications, this would be the license plate from most modern vehicles. See Notes in Overview section on page 10. The camera's surface is too hot and black stripes appear on the screen. The screen is flickering. IR beam is weak  Please check if the power supply is regulated and is within the standard requirement of the product.  Please check if the camera is facing directly toward sunlight or fluorescent light.  Adjust the potentiometer to increase IR LED brightness. See page 11. Verify cable conductor gauge is adequate for the cable run. Using too thin gauge of Power wire can cause serious voltage drop, especially over long distance. If using DC power supply, resistive losses are worse. Try measuring voltage while PSU is connected to camera; if the voltage under load is less than 21 Volts, this is likely a problem. 9.
