    The possibility of doing that is going to be based on what kind of DVR you are using, and whether it has inputs and outputs to allow that (most do)

     

    Usually, it's pretty straightforward, wiring the dry contact outputs from the motion sensors to inputs on the DVR, and wiring the output from the DVR to some kind of alerting device (higher power devices will usually require a relay to be added to handle the load).

     

    Then, it's a matter of programing the DVR accordingly.

     

    thanks for your response! i just need to hook it up to flood lights and wire to dvr to send our sms and email alerts.. hope the zmodo dvr (ZMD-DD-SAN4) can do this?

    i totally forgot about using baluns.. i should try those.. im still a amateur compared to all you guys only been doing this since 2010.. and i just got into digital ip.. hopefully those are more fun and a headache to deal with... haha

     

    numb- i didnt bring my voltmeter yesterday so i didnt have a reading unfortunetly..but i have to assume its a power issue.. it would work on a single cable running straight from the DVR.. ty for your help

     

    tom- again no meter didnt get a reading at the camera end.. but my powersupply was a 19ch powersupply box.. dont know where the box was from cause it was there when i came to upgrade the system.. ty for your help

     

    soundy- i will do the local test soon.. but i think im going to buy video baluns and run cat5... itll be less of a headache i think.. haha i have 3 cameras left to run to that side of the building.. ty for your help

     

    I have never ran baluns before.. but they look easy enough to use.. any advice or tips using them? i bought a box of 1000ft cat5e for my ip cams i got but i might just pick up another box.. any recommendations on what type of baluns i should buy guys?

     

    thanks for all your help

    Sounds like it may be crap cable - either poor construction, or the wrong type of construction. What are the markings on the cable itself, if any?

     

    Are you saying you have a 365' run composed of two 100' lengths and one 165' length all spliced together?

     

    Being a PC-based DVR card shouldn't be an issue, especially not if the other cameras are all working. Only other thing that would make a color camera show up in B&W is if you're using a PAL camera on and NTSC DVR (or vice-versa)... but if these are all the same camera, that's unlikely. Lowest common denominator is probably the cable itself.

     

    i forgot to mention i plug the cameras into the dvr using the 165ft and it was color and the pictures was crisp camera is 650tvl.. but when i add an adapter and connect the power ends it gives me black and white...

    i bought them from ep-survellance... they were precut and made already.

     

    it didnt splice the power i just connected the ends to ends and ran it also i got a F-to-F BNC adaptor and connected the RG59 cables... do you think my current is not strong enough to power the camera to make it color?

    Hey guys thanks for the input.. I tried to call my isp to open my port I went through 4 reps.. Then a salesman.. Then I think after I said no to "business class" they sent me to india to blow me off... I have done installs for a bunch of small business running t1 lines and for me to open a port it is as simple as call isp tech support and they release the port easy as that.. I have never been in more loops in my life... I have a friend that is a network specialist, guess I willbe taking him out for drinks in exvhange for work this wkn... I have 4 dahua ip dome cams and 4 dahua outdoor bullet cams.. Im instructed to config my ip then view my cam through a webcient which when my browser screen pops up I get a invalid website page... My router is totally screwing me... I guess im so use to analog systems.. Ip systems are a pain in the ass.. Ill try to submit some pic of the error or just the config screen after my install tomorrow.. Thanks for all the help guys!

    Where are you able to purchase the DH-NVR3216? I can't find it anywhere on the web.

    I have a cousin in hongkong, ships it to me.. want one? i have 4 coming in in a wk.. you can paypal if you like.. i dont think anyone here in the states have them..

     

    I'm interested - depends on how much you are asking

     

    What model of cameras did you get?

     

    i got the dome 1.3 mp and 2mp and some of the outdoor bullet cams.. 1.3mp and the 2mp.. got 5 of each! i love them! great quality for your buck!

    DH-NVR3216:16 channel@D1, 8 channel@720P, 4 channel@1080P IP camera inputs, It can support HDMI, VGA, USB2.0 and 2 HDDs."

     

    720p is 1280x720 pixels; 1080p is 1920x1080. 1.3MP is typically 1280x1024. Depending on how the system handles the resolution, you'll probably only be able to run six of those cameras on one recorder... maybe only four.

    So do you think i should use those nvrs for my install not all 20 cams are goin into 1 place i have 2 5ch installs and a 8ch install
