    I think you are right on the money as far as trouble shooting goes.. What do the coax connectors look like? How are the conductors? How does the dielectric look?

     

    Do you know what they should look like? Do you know what a sucked out connector looks like? Are they compression? If they are crimp they should be replaced.. as well as the barrel..

     

    I would suspect the underground is your culprit.. are all of the bad cameras fed underground?

     

    you take any pictures of the connectors?

    Is there no where or no one within 5-10 miles that has internet you can use? maybe pay a monthly to help them with their bill?

     

    You could install a system.. but without any access to remotely it won't do you much good.. b/c if someone does break in they will just steal that along with whatever else of value there is...

     

    maybe signage and dummy cameras will serve as a deterrent from any further mischief

    What I meant by hardline, was a good internet service location.. like the house on the property.. those ubiquiti's can travel pretty far with line of sight.. We just did a remote installation where there was really no other choice except satellite .. we used a company called via sat or Excede internet.. the cost is $60 a month for 5down 2 up with a cap of 10 GB a month.. supposedly they don't reduce your upload speeds once your limit is met.

     

    So you have a couple of options.. get your internet access from a home near by that is paying for service or get internet service there at the location. you can create a solar setup with batteries for power out at the unit itself.. I would find a dvr that has alarm inputs and relay outputs and set you security up that way... sensor the doors, maybe some motion detection alerts from the cameras or a PIR that is attacehd to the alarm inputs on the DVR/nvr itself.

     

    I've never used a 3g hotspot type of device personally .. but I would suppose it is possible to acheive what you want.. but I would make sure whatever device you choose, you have the option of hard wiring some sort of alarm system in with it.. keep us informed on what you decide.

    I agree with the above.. HDSDI is your BEST solution but the hD cvi products are pretty nice looking..It's relatively new but all the hardware is warrantied just the same. Where are you located? An all in one out of the box system is hard to beat price wise but you will most likely not be happy with what comes in the kit and end up spending the extra money anyhow.. CVI is cheap and 720. The new building should be wired in both siamese Coax and cat5. I am willing to bet you will be happy with the cvi.. how high are you planning on mounting these cameras?

    Interesting.. I'm about to do something similar to this.. I'm not sure how the Spectra mounts as I've never seen one before. But I am planning on using 1 1/2" Rigid bent on a triple nickle bender into a large J hook.. strap it to the pole and mount the camera to the end of it.. now the spectra might mount a little differently then mine but you could always get a flat 4 hole flange that threads onto the rigid and you should be able to mount your camera or fab something up from there..

    Hi. You should be ok for that distance with cat5.

     

    Can you list the spec of your cat5

    Also can you give your Rj45 connector wiring

     

    Another quick test is remove your switch and put 24v direct to camera (no POE)

     

    This is what I'm thinking.. have you tested your cat5 runs ? Are you certain that your connecters are properly seated? ie no suck out.. the wire is all the way to the end and is making good contact on each end? What wiring scheme did you use? I'm thinking it's a wire termination issue..

    How far is the container from a decent internet signal? Could always do a wifi hop with a ubiquiti setup , power the camera with solar, try to get one with alarm input so you can wire up the doors of the container and maybe place a motion sensor in there that will allow you to receive an alert via email-sms if the container is breached or motion is detected inside.. there are some wireless camera solutions out there as well ... Most of these devices run off of 12vDC or less.. it's just a matter of figuring out the amp/h usage rate of all the devices combined and getting batteries / solar panels that will keep everything powered up over time.

     

    where is this located? State County.

    Why dont you use a round junction box...Second, why coax...why not run ethernet and use ip cameras on a new project...at the very least run ethernet now so that will be an option in the future..

     

    This^^ Make sure you run cat5 with it.. but round J boxes sound like it might be the solution for you .. although I haven't seen low voltage ones.. I don't see why you couldn't use normal plastic round j boxes..

     

    What kind of Camera's are you planning on installing?

    Thank you for taking the time to reply.

     

    As far as the power feed being stranded.. isn't it acceptable industry standard to run power over cat5/cat6 ? I know that optimally you would want to run dedicated power runs in 24ac.

     

    I was worried about the untwisting of the wire and degradation of the signal. I worked in the Cable industry for a number of years so I understand the concept of attenuation and insertion loss.. this I would think would be similar to that.

     

    Its not so much a cost saving issue as it is a wire management issue.. Thank you for your response.

    Thank you for the reply. I know it's another potential failure point.. I just wanted to know if there was any reason not to use them.. IE causing some sort of interference or impedance mis match. The reason for doing it is to keep the amount of wires being ran from power supply to dvr, when the PS is located in a separate location. Or to extend a run.

    Hi All,

     

    So I have a question about using scotch locks.

    Do you use them or see any problem using them to connect the power from cat 5 to a pigtail that plugs into camera power plug?

     

    Secondly, Is there any problem using them to splice into the video feed mid run in order to minimize the number of Cat 5 runs back to the DVR?

    ex. Home runs from the cameras to the PSU, then 4 cameras back on each cat 5 run to the dvr.

     

    Is there an advantage to using a punch down block vs. scotch locks.. other then cleanliness?

     

    Thank you.
