I got a stjiatu branded 4 input capture box hoping to use it to capture 4 seperate analog camera feeds on a laptop inorder to stream them. It uses its own software, which can see the device ok and show them onscreen and do all the usual DVR things (poorly tho) but doesnt seem to install any video capture devices that windows can use for anything else. My old easycap device showed up fine in every app that I tried as a camera or video source. Any pointers for a device that will let the video feeds show as generic inputs into software like OBS or any of the other streaming packages to send things to twitch.tv? Worst case I get 4 easycaps and a powered hub but would rather a single box solution if there is one.

If you have synced both sets of power line adapters to each other, you have made a network loop with them both going into the NVR. You should only need 3 powerline plugs, one at the NVR, and one for each camera. If you try to run 2 independant sets of powerline devices in the same electrical system then you will still have them colliding with each other. The syncing of them is just for the encryption, they will still collide with each others transmissions.

Open a command prompt and do arp -a and check that they have unique MAC addresses. I have seen similar before with some wifi gear that was "unlocked" by a seller which basically involved them cloning the entire eeprom between things, including the mac address.

I need to deploy a couple of analog cameras where I do not want to have ethernet running to. Is there any cheap analog ones that output a widescreen image. The purpose needs things to look the right shape so a 4:3 image stretched out will not be acceptable. If I get a 720P AHD camera that also does composite, do they keep the 16:9 aspect ratio when switched down to composite?

I've resorted to plugging the HDMI out of my recorder into an HDMI game capture box to get stuff off mine. Horrid devices with that rank active x on them. Will be no good when that is finally killed off. My NVR uses the same active x component so I am guessing that I will have to keep an obsolete computer around just to work with them.

I have one the same and it connects to my home lan which is set to AES only just fine. In anycase, I have had no luck finding who the real OEM is, the one that came up from the mac address prefix seemed to be someone that makes USB wifi adapters, which I guess makes sense.

CS is how a whole lens mounts on the camera, the 37mm etc is a filter thread, which has no active parts or can be used to put a crude macro or fisheye lens onto the end of an existing lens. If such an adapter existed you would just get a solid blur like with no lens on the camera as there would be nothing to focus an image on the sensor. I have not seen a thread on the end of any CCTV lenses for a filter yet, but I have not looked at that many of them.

I got a "dahua" off aliexpress. Looks the same but the top of it has no logo on it. Anyway, it found my dahua camera fine, calls it "private" as the type, and it records great. Problem is I was too lazy to set up motion detection or anything since a 3TB drive will last weeks and I only need at most a couple of days. Now today, I have a parcel that says it arrived, but the box was empty. So for the first time I want to play it. Delivery was supposed to be at 10:12, but I can only start play back from 10:00 and then wait and wait and wait. Or put it on faster play which is marginally faster. Is there some setting I have missed to be able to seek the playback scrubber forwards and back? My old analog system could do that fine.

They do have seperate interfaces, but it seems to just be a dumb switch with power internal to them, the cameras get local lan IPs and are accessable from any of the PCs on the lan. Ideally the cameras would not be accessable from the lan, just the NVR's web interface. If the NVR could bring up a second IP interface that was tagged then I could just do it all on the switch, but for some reason none seem to do basic network security practices.

Yeah dick smith are useless. those distances are quite doable if you stick a directional antenna on the camera and the wifi router at the other end of the link.

Can you not just pay for a public IP address? ISPs here that are doing CG Nat are doing that for the same cost as a static IP.

If you have doubts about the cable, then cut it and look at the end, it should be all copper. If the middle is a grey metal, or if you see multiple strands and only some of them are copper then you have junk cable. I have only seen it on dollar store grade patch cables. If you are buying cable from a reputable supplier then you should be fine.

Wifi cameras do not need to have internet access to work, just a wifi LAN, you can then connect your phone or tablet to the same wifi and view it. There may be errors about the cloud stuff not connecting but thats not going to affect you on a internal wifi network. What shops did you go to, and where in the country are you located?

Im not keen on running the lan cables outside to cameras with full access to my internal lan. Obvious solution would be to get a NVR with serveral ethernet interfaces on it. I looked at a dahua which had 4 ports that did power over ethernet, but unfortunatly it seemed to be on the same IP range as the internal network. I didnt have time to see if it was bridging traffic between the ports, but you would assume it was with it having the same IP range. Other option is if I could get a second IP up on the NVR with a tagged vlan, which I could then untag on my POE switch to the ports I am putting cameras onto. and keep the untagged interface on the NVR connecting to the LAN for viewing and admin of the NVR. I have talked to a couple of installers of gear, but they seem to think there is no problem putting lan cables and cameras where they could get tampered with when connected to the internal LAN with servers and stuff on it, so really dont know what the best practice for installations is.

I have a couple of cheap DVR's with 4 analog cameras connected to them. They are generic no brand devices, but they use the CMS software that is compatible with the cheap ESCAM IP cameras from the likes of deal extreme etc. I would like to get a NVR that can connect to the 4 streams of each DVR, and display all 8 in total cameras on a single HDMI output and record all of them to an attached harddrive, as the DVR's location means they dont offer much in the way of security and extending the cables to a more secure location would be costly. After seeing the software is the same as that for my new escam cameras, I bought the escam DVR hoping it would connect to the DVR as well, but while it finds it in a scan of the network, it doesnt actually show anything or give me anywhere to choose the input etc from. I am not opposed to changing the DVR's for something better than the cheapest one I could find locally, but changing the cameras to IP is not really an option at this stage because of both access to the cameras locations (height) and also cabling being hard to swap out. Last resort is to get a PC running the CMS software and leaving that on all the time, but a lower power, smaller, easier to hide away solution would be better.
