Powering the domes-

All the domes will need power. For this dome it is a 24V A.C power supply. The power supply must be

capable of delivering at least 1.5A per dome but it is advisable to allow some headroom so that the psu is not

running flat out. It is therefore recommended to use a 24V AC psu with a minimum rating of 1.7A.

You can either power each dome with its own PSU locally to it or have the PSU’s remotely situated perhaps

near the keyboard or DVR. The domes require a current of about 1.25A when the heater is on and you must

take this in to consideration when working out maximum cable runs.

Please note - The domes heater doesn’t come on until it senses the temperature drops below 0 degrees

Celsius. At this point the dome will need up to 1.7A @ 24V A.C to operate. Please make sure that you have a

sufficient power supply and cable installed to cope with this. Obviously the dome may work okay in the
