Anyone for help
Hi i install one model AI HFW3541E-SA with sd micro card and i want to get notification through the gdmss. When i enable smatplan and go to ivs i set intrusion and if i uncheck the snapshot then i dont get the notifications on gdmss. Only when is click snapshot i get the messages? Why is that? I set the prompt type on gdmss on video but always get the snapshot when it is enable. If i unchecked the snapshot then i dont get it.

Hi. Good idea to use
video .......blue + and blue/white -
power ......all solid colours + stripe -
What is your suggestion...
Using video power balun with rj45 or using passive balun with power connector?
Using ferrules at the end for the passive balun so the wire don't gettin lose or cut is a good idea?

Hi. What is the footage like on playback.... does it still give you same problems
Tom i checked the playback and at night still have waves on the picture but during the day is not
But the contuctor is cupper the braid is cca. I dont think is too big deal
No i will not go too much distance. I care only for the quality of the video. You can see the specs of my cable that i had up.
Ok larnaca is free area. Im living in Limassol. Want to inform me about the store when open. I would like to see your items
Wow. North Cyprus is occupied by Turkey. How about the baluns? Can you tell me a good quality video power balun to change them? Maybe are them the problem
Can you explain why when i change some of them from pal to ntsc all shows perfectly clear? Without any ground loop isolators?
Where you will open an outlet here? Which town and when?
Yes i know that in my country is pal . My dvr is running pal but why some cameras in format pal has waves in it and wgen i change it to ntsc shows perfectly clear?
Is anything else go wrong with my installation?
From 12 cameras 5 have these waves. The only solution i found is that i change the format from pal to ntsc. This stopped the waves but i dont know why. Can anyobe explain this?
I take a video but i cant upload is too big
Anyone can help? Is it groun loop problem?
Had the same problem.3 of 12 cameras has horizontal lines. But i change the format from pal to ntsc and seems that fixed the problem. I cant explain that
Yesterday i installed a system of 12 cameras hdcvi. I used dahua xvr5116hs-x, 2 hfw2241t-z-a, 1 hfw2241e-a and 9 hdw1200em-a, for cable i used cat6 23awg and video power baluns. My problem is that on the monitor (brand new monitor 1920x1080) shows waves on the cameras but from the application p2p it shows perfectly clear. My cable distance not exceed the 30 meteres the longer camera. I checked the voltage on every camera and it is ok to 12,5vdc. My power supply is 12vdc 15 amp it is very enough.
Can anyone help me with this?
Are u a supplier?
Im based in Cyprus. Usually i install 2mp hdcvi cameras over utp cat6 using video power baluns. But i want to try the rg59. I dont know if i had any problem with rg59 cca for 2 mp cameras but some clients ask for 4k cameras and the balun is up to 4-6 mp support and i think clarity over coax it will be better
All cables localy are cca. Ccs condactor and cca braid. Why this is important? Because it is very expensive to get it from usa or anywhere esle outsife europe. I mean the delivery cost and taxes import
Can you send me a link from this supplier?
