Which kind of cable is suitable for coax system?
- It’s necessary RG59 type up to 300 mt or different but respecting 75 Ohm of impedance (not suitable satellite cable).
-
What can happen when using no coax cable or cable with different impedance?
- The picture can appear crummy and without contrast.
-
Is it possible to install a monitor at 900 mt far away from camera?
- Yes, by using a video amplifier sch. 1840/250 next to the monitor.
-
How many video distributors 1794/4 can be powered on a system?
- Up to 10, for furthers it’s necessary a supplementary power supply sch. 789/2 for every 20 distributors, providing 2 additional wires on the riser.
-
How many video house phone can ring together with power supply 789/5B?
- Up to 4 video house phones.
-
Is it possible to realize an implantation with a mix of black and white and colour video house phone?
- Yes, providing the push button panel with a color camera.
-
Is it possible to add a control cctv camera as well as the video push button panel?
- Yes, with relay box 788/51 to allow a self-insertion from the monitor to the cctv camera.
-

-
Is there a table support for video house phone?
- Yes, kit 1702/92 specific for Atlantico.
-
Is it possible to utilize video distributor for TV antenna in alternative of 1794/4?
- Not suggest able, because video signal could work in low frequency, usually by a value of 1 Vpp.
-
Is video house phone Atlantico suitable both in coaxial and 5-wires system?
- Yes, it is, using dedicated bracket 1202/90 in coaxial implantation and bracket 1202/955 in 5 wires ones.
-
Is it possible to regulate call volume on Atlantico?
