INSTALLATION AND OPERATION

1. UNPACKING and HANDLING

Each unit is shipped assembled and factory tested.

Ensure that all accessories are removed from the container before discarding packing material

2. MECHANICAL INSPECTION

Inspect the front and rear of the equipment for shipping damage. Make sure the equipment is

clean, and no connectors are broken, damaged, or loose. If equipment appears to be

damaged or defective please contact your distributor or SecurityTronix at 1-800-688-9282 for

assistance.

3. SPECIAL ATTENTION

a. The installer must comply with electrical safety standards. There must be sufficient

space between the camera’s power supply and video line and any high voltage

equipment and/or cables.

b. To help ensure the camera’s life and proper operation do not point the camera

towards the sun or strong light.

c. Do not install the camera in an environment where the temperature is above 113F.

The camera should be installed in a cool and spacious environment.

d. Do not install the camera near a magnetic field or a high-power motor.

e. Only use a dry cloth to clean the camera. If there is dirt that is difficult to remove wipe

gently with a mild detergent. Never use strong or abrasive detergents.

f. A 12VDC 350mA power supply must be used. AC power cannot be applied. AC

power will damage the camera and void warranty.

g. Only qualified installers are allowed to install, test and disassemble the camera.

h. The camera is a low voltage product. If installed outdoors proper safety and

lightening grounding are required.

4. WIRING CONNECTIONS

a. Connect the power supply’s DC plug to the camera’s power outlet.

b. Connect the camera to the monitor with a 75Ωcoaxial video cable.

c. Connect power supply’s AC plug to a suitable AC power outlet.

d. Adjust the lens direction according to the required surveillance area and environment.

6. TROUBLESHOOTING

a. No picture after applying power –(i) check all plugs and cables are securely

connected to the proper connectors; (ii) ensure your power supply is providing the

correct voltage and current.

b. The picture has ripples –(i) check to see if the power supply is experiencing AC

ripple, if so a filter may be required; (ii) determine if the monitor is faulty; (iii)

determine if other peripheral equipment is causing ripple and if so make the

necessary adjustments.

c. The picture background continuously changes color –a fluorescent lamp’s magnetic

field may cause color roll, therefore, reduce the number of fluorescent lamps or

increase the distance between the camera and the lamps.

d. The picture appears smeared –(i) the power supply voltage level may be unstable,

therefore, try another power supply; (ii) ensure the cables are correctly connected

and/or the cables are of the correct impedance.

e. Other interference may require a SecurityTronix ground loop isolation filter.

f. Additional troubleshooting assistance can be found on-line at www.securitytronix.com

in addition to support from SecurityTronix sales engineers at 1-800-688-9282, option

3, then option 2.
