local electrical supplier should have solid copper cat5 or 6 also I would invest in a cheap wire mapper to check your cables. make sure the plugs you get are for solid wire and rated for whatever you go with cat 5 or cat 6. get plenty of extra plugs as they are easy to cross up when installing.

I would second getting an electrician involved. In our area we got stopped on a job pulling low voltage wire through conduit as the inspector was not happy with the firestop process, their was no code violation, and he could site no local codes but we knew better than to fight it as we would run into him on future jobs. If your local contractor has a good reputation and his approach is solid he may be your best option also if the system has been in place for a while it may be time to upgrade. I look at some of the cameras we put in 5 years ago vs today's Hd cameras and one can really see the difference

if you try it and it does not work you would need a 1 in 2 out powered splitter probably around 25.00

try only using one or two pairs for power and see if that helps

Do these cameras have addresses like when you link up multiple analog PTZs usually set by dip switches in the analog world could be that there are duplicate addresses that work fine on separate runs but cause problems when things are connected together.

If you know this client well ask her how much she paid for the no support unit. I would like to know how much people really save. If she will tell you then you can factor in your service charges it would be interesting to see if there really is a savings.

Is this an analog camera? If it is it sounds like a ground loop. make sure everything is grounded and then make sure the camera cable is not running for a long distance parallel to the mains power.

safe as in "I lost control and it hit someone in the face" how do you deal with that good insurance?

did you run any tests to see if you are getting interference from another source? could be a new source of RF if this is an unlicensed part of the wireless band.

make sure the account you are using has remote access as allowed. also can you ping your router from outside. check your port forwarding etc many threads on this subject

why would you consider a NVR that is not sold in us and only has Chinese/ Russian for language ? Go with something that you can get service on.

excellent advice +1

check out Viking electronics they have a 12 unit system that can be piggy backed to expand. They use a regular analog phone handset to communicate and release the door.

Geo has a program that is called vital sign monitor. You can also set up a setting to notify you of individual camera failure. I agree with other poster get a good POE switch and put it on a good UPS and your failure rate should be very low.

what are you using for a power supply and are you using unused pairs on your cat 5 for power.Are the power supply and the dvr on the same power outlet

Does the camera have a built in microphone or audio in and out? ETS has microphones and power sources for cameras with audio in and out.

The vendor you purchased it from should be able to provide this type of basic support.

Yes I would do jacks on both ends

Anybody used a quality wireless camera? I have a potential customer who wants to observe a room with no recording (for now) and it would need to be wireless. I have looked at Geo and Axis and used those products but never the wireless options. I would like to avoid the very low end stuff. Any other quality options are welcome.

This will be interior no infrared or audio. I looked at this site the other day and it may be possible to get a cable to it. it actually has a high ceiling and I am going to look at the axis 360 camera but still am interested in a wireless option if it comes to that

If you go analog how are you getting power to each camera? It looks like you have a pathway if you have a network all ready in place I would go IP/POE.

It always seemed to me that installing plugs was harder than installing jacks. I prefer the patch panel patch cord at the Data closet end and a jack with a patch cord at the camera end. that way if you have to move a camera you can just change patch cords to the desired length provided you are still withing the 100 meter limit. whatever you end up doing at minimum be sure to wiremap all the runs.

Try and get the dvr and power supply on the same power line also ground the power supply and the dvr. If you find only one camera is causing the problem try instlling a ground loop isolater

sounds like a ground loop are you using baluns on the cat 5. a

look at PI MFG they have several different baluns that incorporate power as well as video signal. Prices are reasonable.
