    Hi guys ok i port forwarded 80 and 34567 to dvr 1 and it works..I tried to port forward the same ports to dvr2 but says " pinhole conflict xxxxx"?? Is it because I can only access one dvr on the modem ?

    Do you mean modem or router?

    You will need to change the external port numbers for one of the dvr's

     

     

    its all in one the ATT modem/router and the ips on the dvrs are different.. one is 255 and one is 254. on the modem configuration it shows " localhost " and " localhost1" those are the Dvr's. but only none works? anyway to combine both Dvrs as one on an app to view all cameras on one screen? 30 cameras

    You should either stick to one topic, or give all the detailed information on every topic you open.

     

    What cable are you using? WHat material is it made of? What thickness? You are using AHD at what resolution? What baluns are you using? I am not saying I need that information to help you now, but I am not going to chase the details on your complete installation every time you open a new thread. Just saying.

     

     

    im sorry but this forum isnt helping me at all thats why i have seperate threads.. im just getting laughed at and disrespected with childish remarks.. and ive read many other posts to and i see the same childish remarks and bashing from the supposed " helpers" .. it seems to me like this forum needs a little speach from the moderators to help people without bashing them..

    How does starting separate threads resolve that problem in any way? You still have not answered his question so he can help you.

     

     

    im using cat5e , i believe 24gauge and ahd 720p , regular baluns.. i tried the cable and those baluns using 2 200ft test cables at my shop and they should clear images?

    coax of cat5? first question needs to be answered. Are you getting paid for this install if so why would you make it so cobbled up? make individual runs for each camera and use correct wire form what little is posted I would at first make sure I have the proper seperate power wires for each camera. I know you can use a balun with cat5 and use the other pairs for power but I am not a big fan of that approach.

     

    Yes im getting paid for this. There is individual cat5 to each camera.. 2 pairs for neg power and 1 pair for pos.. video is blue for pos and blue/white for neg.. basic baluns that i tested out and worked fine with 2 200ft sample wires at the shop.. they are all running to the supply boxes .. one of the boxes 30 amp, has 11 camaeras . the other a 10 amp box has 4 and anopther 10amp box has 6 cameras and the rest on a 8 split wall wart and 3 individual wall warts.. so they all have enough power i assume? but when the irs lit up the picture on a lot of cameras went bad? i turned up the Voltage on the boxes and the pictures did get a little better..

    The power supply boxes make for a cleaner install for me. I just did a car dealership this week (TVI) and used a power supply box in their server room where the DVR was.

     

    But I do have customers where the individual power supplies were used. As far as longevity, I dunno...the little wall-warts are still chugging along after like 8-10 years on some of these installs I'm coming across.

     

    When I'm not using POE off a switch or NVR, I prefer the PS boxes for a cleaner install and the fuse function. Also much easier for when (not if) the customer wants more cameras later.

    Guys this install is driving me nuts..

    I've tried multiple power supply boxes.. 3 in total and 8 split wall wart and 2 single wall warts.. Some cameras will just not get along with other Cameras! But now a new issue.. Got pictures clear and thought I was done.. Night vision irs kicked on and I'm having horrible picture quality with horizontal jumping lines ? Surge? Not enough power? But I have 9 cameras on a 30 Amp box , 4 on a 10 amp box , 7 on another 10 amp and the rest on the wall warts.. Enough power I assume? Some runs are up to

    175-200 ft Max.. It does seem most of prone ones are the long run ones.. I'm using a pair for positive and 2 pairs for negative ? That should be fine ? What am I doing wrong? Amy help is appreciated I'm almost going crazy with this install .. Never using cat5 again ,sismese coax all the time from now on lol

    I've done what they recommend but still have thes issues. Any help would be appreciated buddy..

    There are way to many variables...

    Did you buy quality baluns? Did you replace the junk cable?

    Have you tested the cameras with the DVR on a short run?

    Are your ethernet runs direct from the dvr to the camera or did you punch it down somewhere or use a coupler? Are your connections good?

     

    I tested 2 cameras on separate 200ft wires with same baluns to the dvr at my shop and thu we're clear pictures..

    So the baluns and cables are good.. I'm thinking it's the boxes or

    Is it becuase all those cables bunched up together? That's 4 pairs of 16 cables near each supply box .. Will all thos wires cause

    Interference , I mean how

    Else am I supposed to connect to dvr and ps box unless all are

    Within feet of

    Each other ? And all runs are are direct from dvr/box to cameras

    hi guys, im installing a 32ch of rhte first time, and using cat5 with passive baluns on a AHD system for the first time.. and what a mess.. i wish i had of stuck with coax..

    ok i have all 32 cables coming into the room together and split in half.. and then split the video twisted pairs from the power video pairs.. what a mess...

     

    im using 2 16ch 10a supply boxes..

    which i believe are way under powered for 16 AHD cameras with 24-32 irs?

     

    im getting lines in many of them and wavy rolling pictures.. not on all but on most.. im thinkg ground loop becuase of all those wires and this whole setup being all within feet of each other?

     

    im going crazy here.. some cameras cause all the otjhers to go crazy.. even if i put them in a seperate wall wart ? ill upload pictures soon..

     

    oh yeah here is how i wired them

     

    blue pos vid

    blue/white neg video

    green pair and brown pair for neg power

    orange pair for pos power..

     

    does using different styles of baluns on each end cause any problems? i crakced open both types and they have the same coils in them " simonsen123 "344e-150mh "

     

    oh yeah some runs are up to 175-200ft..

    Your first problem is how you have wired up your system

     

    Your biggest problem at the moment is how you have connected your baluns ..... Pair for video + and pair for - ..... This need to be changed before anything else .... You should ONLY use 1 pair IE blue for video + blue white -

     

    Rest of pairs look at ak post

     

    This needs doing to see if you do have problems

     

     

    will do, its my first install with cat5 , now i learned something.. thanks

    Hello naiefelyemeni.

    I suspect part of your problem is that you've used

    1 pair for video pos and 1 pair for neg video
    To use twisted-pair for video, the video must travel through only one twisted-pair. So connect video pos to one wire, and neg to the other. The remaining twisted pair is unused (or you can use the wires for power as well). Use a balun at each end (camera and DVR).

    This might fix your video problems.

     

    You might be able to use copper-clad aluminium for short distances. At least it's not as horrible as copper-clad steel. Full copper is best for CCTV.

     

    The camera works without the negative power terminal connected because the camera designer has done a bit of a cheapy, and hasn't used an isolated power supply. The power supply negative is connected to the coax shield inside the camera.

    Basically you have a ground loop, which could mess up your images. Since you have a spare twisted-pair, you could try using this pair as an extra negative (ground) for the power supply. This might help stop some of the power supply current from travelling through the video twisted pair.

     

    So your cable would have:

    one pair for video

    one pair for power positive

    two pairs for power negative.

     

     

     

    Makes sense, your making me feel a whole lot better today, cant wait to go back and try that out! thanks!

    You may use "cat5" for AHD cameras, but RG59 cable recommended. Why baluns? I do not like to put Baluns at both ends. Why at the camera's end?

     

     

    so i dont need them at the cameras end? i thought i need them on both ends to balance the line? and how would i connect it tot the camera end anyways? since i used cat5? unless i can use this at teh camera end?
