coituma Posted June 4, 2016 Author Share Posted June 4, 2016 Yes is about 100 meters, No I have not check the power yet, what is the power rating am expected to see? That is the standard power for camera. Quote Link to comment Share on other sites More sharing options...

PeterJames Posted June 4, 2016 Share Posted June 4, 2016 You need to compare what the psu is putting out with what is at the end of the 100 meters on load. If its DC and you have a big volt drop theres your problem , you can raise the voltage by doubling up cores or using thicker cables but it would be better to power the cameras locally Quote Link to comment Share on other sites More sharing options...
coituma Posted June 4, 2016 Author Share Posted June 4, 2016 Yes is DC. How do I double the core? Is RG6 not good? Is connecting power locally better than using power box? Thanks Quote Link to comment Share on other sites More sharing options...
PeterJames Posted June 4, 2016 Share Posted June 4, 2016 What cable are you using for power? Powering locally means plug the power box in at the camera. DC will lose voltage over 100 meters it really depends on the cable size Google ohms law for more info. AC travels better over that sort of distance. RG6 could be a bit small for 150 meters I dont use coax personally, we use cat 5 with Baluns over that sort of distance we would us active baluns Quote Link to comment Share on other sites More sharing options...
al-yeti Posted June 4, 2016 Share Posted June 4, 2016 Measure voltage at camera , what is it? Quote Link to comment Share on other sites More sharing options...
coituma Posted June 4, 2016 Author Share Posted June 4, 2016 I use RJ59 with power attach to it from camera to power box. I have even use balun to bridge it between the power box point to that RG6 cable and it shows well, but after some time trips, but if unplug and allow to discharge for sometimes it come on again or when it sames the current is more steady it works. Note: this connection pass through three building. One house the camera, another the power box and finally the third building the termination point where the DVR is. I also thought about using cat6 but because of attenuation I did not, please does power loss it strength with long distance? Quote Link to comment Share on other sites More sharing options...
james.wilson Posted June 4, 2016 Share Posted June 4, 2016 you are sending power down the coax as well as the video? What converters are you using?

coituma Posted June 5, 2016 Author Share Posted June 5, 2016 How am I sending power to the coax, is running on it own and I don't understand about the converter because am using non or am I suppose to use one and what for? Thanks Quote Link to comment Share on other sites More sharing options...
