Camera does not
work.

1. The Camera requires proper power
and signal connections.

2. Sufficient power must reach Camera
location. Each Black & White camera
requires 12V DC, 300mA. Each Color
camera requires 12V DC, 100mA.

1. Disconnect and reconnect power supply. Make sure all other connections
are secure.

2. Long cable runs will diminish power. Either use a larger power supply
that gives each Camera sufficient voltage, or place power supply closer to
Camera so that a shorter cable run can be used.

Gray, hazy, fuzzy, or
blurry picture.

3. Camera is out of focus.

3. Turn lens clockwise or counterclockwise until picture is focused.

Difficulty inserting
Lens into Decora
plate (In-Wall Models)

4. Lens is designed to fit tightly into
Decora plate. Care must be taken to
prevent the Decora plate from cracking.

4. Place Decora plate on flat surface. Use both hands to center lens and
press all corners down simultaneously. Repeat until all four corners are
snapped into place.

Camera does not
work.

1. The CAModulator requires proper
power and signal connections.

2. All connectors must be grounded.

3. Sufficient power must reach Camera
location. Each BL01 requires 12V DC,
300mA. Each BL02 requires 12V DC,
100mA.

1. Disconnect and reconnect power supply. Make sure that +12V and
Ground wires are not reversed. Make sure all other connections are secure.

2. Make sure all connectors are grounded.

3. Long cable runs will diminish power. Either use a larger power supply
that gives each Camera sufficient voltage, or place power supply closer to
Camera so that a shorter cable run can be used.

4. Camera is out of focus.

4. Turn lens clockwise or counterclockwise until picture is focused.

No Video.

5. Video connector must be grounded.

5. Use the Black Common Ground Wire (-) to ground the Video connector.
