    Hey guys,

    I hope you can help with my upgrade.
    Currently I have 6 CCTVs, 4 in the garage, 1 at the front gate and 1 in the backyard filming my property line. They are all analog, feeding over coax to the NVR in the basement.

    I would like to upgrade the system to digital, some nice 8MP cams from Hikvision.

    The plan is as following: Install an 8 port TP-Link POE Switch in the false ceiling in the garage. (Max 30W per port, 121W total)
    Run Ethernet cable from the switch to the new cameras in the garage. Connect the switch to Ethernet over Coax adapters (LINK), use one of the existing coax cables running back to the server room and use another EoC adapter there to connect it to a digital NVR. Same for the front door: Install POE switch, connect to new cams, use Ethernet over coax adapter to connect switch back to NVR.

    Does anyone see a problem with that?

    Obligatory MSpaint schematics ;) cctv.jpg

    Thanks a lot for your help.

    reconsider 8mp cameras unless you have plenty of light...more mp does not mean a better image..
    I would suggest running new ethernet back to the house..for a bit more than the cost of the adapter, you can have a proper line..

    Thanks for the quick reply. Unfortunately it is impossible to run new Ethernet cable. The walls are reinforced concrete and the cables are buried in it. I have tried tugging on the cable to maybe pull the Ethernet through the pipe , but they don't budge. The cable from the front gate runs beneath the kitchen tiles. I'd have to redo half the house to pull new cables.

    Thanks. So besides the converter quality my plan is OK? Should I go for 6MP cams in the garage instead? You mentioned light, so I assume I can use 8MP at the front gate and property line.

    What kind of system do you have in place now and what is powering your analog cams? The reason I ask is you might want to consider re using existing cabling with hdcvi cameras with a tribrid DVR. You could keep your wiring and have a really good room to expand with IP cameras in the future. The Quality is really good and the price of those cams are VERY good. I have used these and they are rock solid. You might be limited to 2 MP Cams but who cares as fenderman says, you DO not need 8, 6, or 4 MP cams to do a GREAT job.

    I'm using a Hikvision DS 7808HGH with some bullet cams. IMHO the quality is pretty bad compared to the Hikvision IPTV setup I have at the office.
    I also quite dislike the separate box for the power and the coax termination that is attached to each cam.

    Edit: I should add that the garage opens into a shared basement garage, it's not pitch black there is always light. It's attached to my basement, but technically part of a parking structure.

    Yes I have seen them on the market now. I have not used any because the DVR's I have running out there are only good for 2MP. I think they have a newer version of something like a Pentrabrid DVr that would utilize the 4mp cams. Thanks for the heads up bud

    Just checked the cameras I got installed.
    "DS-2CE16C3T-IT3 HD720P EXIR Bullet Camera 1.3 Megapixel"

    If I upgrade, should I stay with Hikvision for NVR or go with Blue Iris?

    The cameras now got 3.6mm lenses. Seems fine for the property line, but should I got shorter for the garage?

    I know this is IPcamtalk but I would personally look to see if LTS TVI or Dahua TVI will suit your needs. No need to put new cable in and the quality is pretty much the same.

    If this was a NEW install then I would do IP.

    I like the new Matrix IR (double EXIR basically) range

    We have been using quite a few Dahua 4mp hd-cvi cameras and dvrs. They are all working great, resolution is great, and there is no lag. I would use them in a heart beat if I had coax already running. Plus, they are about half the price.

    I agree wholeheartedly, I have used them with mixed systems and they have been rock solid, great pictures and very stable. I have been doing a lots of installs as of late and I hate having to go back and tweak things. The HD CVI are really set it and forget it cams..zero issues. Most customers don;t give a crap what kind of cams you install as long as they work and have a quality picture.
