    OSD Controller Settings

    To set the video format via the OSD controller, move the joystick controller in the direction of the desired setting, hold for 5 seconds, and release when the camera restarts:

    Direction Format Setting
    Up AHD
    Down CVBS/Analog
    Left TVI
    Right CVI

    Note: Do not press the joystick in when setting different modes.

    Before Starting

    1. Use the camera within the given temperature and voltage limits.
    2. Do not point the camera at the sun — heat could damage the camera, even when not in use.
    3. Do not subject the camera to strong vibrations.
    4. Do not mount the camera in areas exposed to radiation, strong magnetic fields, or strong electrical signals.

    Installation

    1. Run a 12VDC power supply wire and a video cable with a male BNC connector through the wall to where the camera is to be mounted.
    2. Loosen the outer case ring and remove the case from the base. Note: The camera ball is not attached to the case or base and sits loose inside the case — be careful when removing the case; do not drop the camera ball.
    3. Mount the base to the wall using the three included mounting screws. If the wall is drywall, brick, or similar material, use the included screw anchors.
    4. Run the camera's BNC and power connectors through the camera base, and connect to the video and power wires run through the wall.
    5. Put the case over the camera ball and onto the base.
    6. Holding the case loosely on the base, turn the camera ball to the desired direction. Use a small screwdriver to adjust zoom and focus via the holes marked "ZOOM" and "FOCUS" on top of the camera ball (varifocal models EV-Y2501-AMWQ, EV-Y2251-AMWQ, and EV-Y2501-AMGQ only). Note: Before securing installation, check both day and night images, and adjust so no objects block the camera's view.
    7. Use the OSD controller joystick to adjust camera settings (see the separate OSD manual).
    8. Once the ball is pointing in the desired direction, tighten the outer case ring to secure the camera in position.
    9. Perform a final test of the video camera and monitor.

    Troubleshooting

    Symptom Check
    The screen is black Camera is powered up; power supply polarity is correct; monitor is powered up; video cable is connected properly.
    Image is foggy or washed out at night No objects very close to the camera; no highly reflective objects in the scene.
    Screen image is dim Clean the lens with a soft cloth; check the light source is adequate.
    Screen image has poor contrast Adjust the monitor's contrast knob; change the position of the camera.
    Screen image flickers Change the position of the camera; check cables and format setting.
    Screen image is distorted Change the position of the camera; check cables and format setting.
    Camera case is hot Check that the correct power supply is in use.
    IR LEDs do not turn on Check that the correct power supply is in use.
