3.2 ELECTRICAL

3.2.1 Video

EPTZ 100 provides a composite 1 Vp-p video output PAL/NTSC (video system depending on ordered
version) with a BNC cable socket.
Cameras and video displaying or processing equipment (DVRs, switchers etc.) require cabling with 75
Ohm video cable, e.g. RG-59, RG-12, and suitable BNC plugs.
Due to inappropriate absorbability, 50 Ohm coax cable (e.g. RG58), antenna cable and further types of
coax cable are not suitable.
Make sure that the video input of the connected video device is terminated with 75 Ohm.
When interconnecting transmission lines (twisted pair, fibre optics, radio) to the speed dome, ensure the
accurate receiver calibration.

3.2.2 Power

EPTZ 100 is powered by 24 VAC voltage. Connector is a 5.5 mm power cable socket.
Make sure that the used power supply complies with the power requirements of the speed dome (19 W
max.). 24 VAC / 1 A power source (or higher current) is recommended.
NOTE: If the power supply is not located near the dome camera, make sure that the installation cables
have sufficient diameter, otherwise the voltage drop over the power line will cause malfunction of
the speed dome (min. 21.4 VAC at speed dome power input with active PTZ motors is required).
NOTE: Do not connect the power until all installation steps are done!
