Thanks, I had the same issue, changing the DNR back to 50 fixed it.

Hello, I'm having an issue with a Hikvision DS-2CD2142 cameras and iVMS-4500. It seems to have a hard time keeping up with the live video stream (I see a couple of seconds then freezes for 5 seconds... repeat) This issue is only when I connect directly to one of the cameras. If I put the cameras on a 7604 NVR and then add the NVR to the app, the live video is perfectly fine for all cameras, as soon as I remove the NVR from the app and add a single camera directly the stream can't keep up This is using local WiFi and custom sub stream (352x288 10fps 128k) on the iVMS app on a Samsung S4 and Asus 7" tablet.. When viewing through a laptop browser, the main stream (2688x1520 20fps 8144k) is perfect (and obviously so is the sub stream) I can't understand why the camera/app works through the NVR but not directly on the camera. Any help or suggestions is appreciated. Thanks.

Hello, I recently installed some IP bullet cameras (Hikvision 4mm 2232) I have come across a problem with some youths throwing small bricks, turns out one is a crack shot and managed to damage a camera from a fair distance away I looking for something to protect the camera, maybe like a cage? Does anyone have any experience or recommendations? How affected will the camera view be from inside? I'm in the UK, so any potentially stores would need to be UK. Thanks for any help.

Thanks again for the responses. So am I right in thinking that is I use 'Star' wiring I will need a distributor and if I 'Daisy Chain' from one camera to the next I wouldn't need a distributor? I couldn't find anyone selling BBV/Pelco distributor. I did however find a few places selling this particular product - Genie RS004 - http://geniecctv.com/product/data-transmission-3/ Would this work for 3 cameras/2 controllers? Should I forget the CAT5e and and go with the Belden screened? Will this be more reliable? Thanks

Thanks for the replies. Both the DVR and the Joystick do only have a single RS-485 connection I live in the UK and can't seem to find any the Data Signal Distributors as suggested. If I decide to go from camera to camera would I still need the distributor?

First post here and have a few questions I am looking to upgrade 3 of my 6 analog dome cameras to PTZ domes. Currently each camera has Siamese RG59 cable w/power. I will be purchasing a joystick and 3 PTZ domes, both supporting RS-485 for control. Nearest camera to be replaced is about 30M away from the DVR and furthest is 60m. Each camera is about 15m from the other. My questions: 1) What cable I should use for adding PTZ control. My original thoughts were to run CAT5e (I have a couple of half boxes spare) but after doing some investigating it seemed like some people had issues with RS-485 over CAT5e and warned not to use it. 2) Will I need to get a cable from each camera back the joystick/DVR or do I run a cable from one camera to the next? (I don't mind either) 3) Is it possible to use both a joystick and the DVR to control the PTZ or is limited to one controller over RS-485? Any help/advice is appreciated.
