    Nonsense. The original diagram is just fine. There will be no difference. This is basic networking.

    I would suggest checking your power side connections too. I had one camera break a negative wire, and it still worked but caused an interference on its channel and the matching one (Hikvision DVR). As soon as I reconnected the wire both cameras were fine.

    Your service cable will fit the full cnb ranger including HD analog i have 100s of them out ..... even profile picture is the same cam and that’s been there since I joined. Now that it’s apart you can see why I suggested doing settings at night

    The brown is for cnb in-line controller. Only altered the back light and dnr.... not worth the extra work if you send cnb a picture they will help

    Hi. Very good camera in its day. You cant connect that camera via rs485 only the 50 and 70mm had rs495 and lens protocols all your camera controls are behind the lens you need to remove 4 screws around your lens cover and pull it away ...... you will see the lens adjustment and the dip switches. I highly recommend that you do the camera settings at night for you to get the best result...... saves you removing lens cover all the time.. concept are just a uk reseller the makers are CNB tech

    When you changed the power adapter it may have allowed the camera to default to a different setting as tomcctv said check if the camera and DVR are set to PAL/NTSC (they should both be set the same)

    Hi I would keep testing simple ...remove camera and plug it into another location ..... if this is just a camera swap to start with it could just be the camera faulty are you using standard analog analog or HD ...... and have you got the right region camera PAL / NTCS

    Sorry just read your post again and seen Coax in the title. Check the termination switch/setting on the DVR if there is one! Using a voltmeter set to Ohms go to the camera and check the resistance of the coax cable as it goes back to the DVR, it should read 75 ohms plus the resistance of the cable so probably about 80 - 100 ohms depending on the cable length/quality. If you are reading in the M ohms range then the cable is un-terminated, or has possibly been damaged, next go to the DVR and remove the camera signal lead and measure the resistance of the video input this should be 75 ohms.

    I can't answer any questions about how many cameras you'll be able to view at once, because I'm relatively new to video surveillance gear, myself, and it'll depend upon your software in any event. But, as a retired Systems, Network & TelCom Admin with over 25 years experience building and maintaining networks (LANs, WANs, WLANs) for a living I'm going to suggest cameras <-> switch <-> powerline <-> router <-> powerline <-> NVR is probably not going to result in a happy outcome. First of all, powerline adaptors have highly variable performance, depending upon a variety of unpredictable factors. At the very least I'd obtain a pair and do network bandwidth, latency and error rate tests between Point A and Point B, then Point B and Point C before proceeding. I'd be surprised if you got sufficient low-error-rate bandwidth to support eight video streams. Secondly: It has been my experience that most routers (and I'm making the assumption you probably have either a common consumer-grade or cable company device) tend to be sub-optimal as network switches. Particularly common WiFi routers. In my opinion, based on experience: Switches to switch, routers to route, and WiFi access points to provide wireless access. Avoid WiFi and powerline where wired is feasible. As to WiFi vs. powerline: Whichever works best, which is highly site-dependant.

    Forget the ryobi if you want to get your work done with tools that can handle it, not ones that are for light duty homeowner stuff. I have 98% makita....here is a link to the vac (yes, they do have one) i have it and it's great...they have either vac only, if you already own makita battery and charger or they sell full kit... http://www.amazon.com/Makita-BCL180W-18-Volt-Lithium-Ion-Cordless/dp/B0039ITKLU Check out this pic of my enclosed work trailer....2 shelves of mostly makita power tools (cordless)...also have some corded sds drills and what not, not in this pic.. You can see the vac in this pic though

    I have to say that the standard of CCTV work I have experienced in the UK is very good in the main. I have learned a bit from remedial works, I have seen the way other's do things and in some cases I have changed the way I do things because I have seen a better way of doing something.
