INSTALLATION TIPS

1.) Power Consumption - Amperage/Voltage
It is of utmost importance that the proper Voltage and Amperage is used when
applying power to your VITEK Alpha Series Dome Camera. They can be pow-
ered by either 12V DC or 24V AC (except for the model VTD-A4F/I - 12V DC
only). Always use a UL Listed power transformer.
The Amperage must be measured at the camera location. It is very important
that the camera receives no less than the required Amperage or it will be
"Starved" and eventually die out. Cameras with Infrared LEDs require substan-
tially more Amperage than others so please refer to the Specifications (page
24-26) for the camera you are installing.
2.) Extending the Power:
The cable may be extended up to 100 feet by using 18 Gauge (or thicker)
stranded wire - possibly longer depending on the amperage of the transformer
(see appropriate electrical guides to determine resistance). Simply cut the
power connector off of the transformer and splice the wire using a wire nut or
solder and Electrical tape for isolation. DO NOT ALLOW THE BARE WIRES
TO TOUCH ONE ANOTHER.
3.) Extending the Video Cable
Always use 75 ohm copper braid coax (RG59U or thicker) for video signal
transmission up to 500 feet - possibly longer depending on the grade of cable
and percentage of braid. VITEK Alpha Series Dome Cameras utilize BNC
Video connectors which come in male or female in order to extend the coax to
the desired distance (see appropriate installation guide to learn how to properly
install a BNC Connector).
