    Static or DHCP for IP cams?

    In fact you can likely export the existing reservation list, edit the values to be whatever the new subnets are, and import the revised list with MAC addresses all filled out to your new DHCP server so that everything you wanted to have a reservation will with minimum effort. :D

    Static or DHCP for IP cams?

    This is what we do too. Also, in my unusual use case it is common for camera to be dynamically installed at the last minute and we haven't pre-reserved IPs for all of the cameras in inventory so it ends up being "Plug it in, look at the switch to see what IP it picked up, and then decide if I...

    Do you use a patch panel?

    This is the part many people skip. A lot of my thinking on this was driven by Selecting the Correct RJ45 Connector | trueCABLE which I do note is talking about high bandwidth connections. I really like their writing style, although it is focused on a much more performant usage of ethernet than...

    Temporary POE connection.

    Ok, so this makes a lot more sense. Somehow in the original post I missed that it was a 1:2 PoE splitter instead of a simple injector. So I was trying to figure out how two cameras were going to be powered off of a single injector. Sorry about all that. Does the uplink cable come into the box...

    Temporary POE connection.

    What role is the box fulfilling?

    Do you use a patch panel?

    One thing to keep in mind is that if you’re going to be poking around where your cables are, having some sort of strain relief is important so you don’t accidentally make a good connection intermittent. Or just pull it off. :). So if this is a switch where some cables are permanently mounted and...

    Need help choosing a UPS

    APC, Vertiv/Liebert and other Tier 1 UPS manufacturers already offer LiFePO4 options (at a significant premium) so the chemistry itself is known to be safe. It’s always possible that a careless manufacturer makes a design that is bad but that is also a risk with SLA. One thing to look out for...

    Remote (off-network) connection to my Hikvision NVR...public IP is CGNAT IP

    Tallscale is amazing. Just absolute magic.

    Optical signal transmission

    I would say the likelihood is 95% there is another connection between those two endpoints and you are causing a loop. (Or the fiber is making a U turn and you’re connecting both ends of it to the same switch. I’ve done that with copper going through a wall.) Especially because you said that the...

    Temporary POE connection.

    How are you sealing the mains power input to the PoE injector? Is the box purely an indoor item that is a convenience for holding the injector and a permanent cable receptacle vs having them floating free? In any event, there are connectors like you need with built in cables for the inside the...

    Is my neighbor interfering with my cameras?

    Is your phone the only source to view the camera footage?

    Doesn't this panel create more problems down the line?

    If you're running bulk wire, you'll need to terminate each end with something. Punching down is in my experience a bit harder to get right than crimping a plug. But not so much harder it's worth crimping your own cables to use a passthrough jack. IT Professionals usually hire an outside...

    Zosi camera - how to access

    Interesting, but not necessarily nefarious. WeChat in China is beyond WhatsApp in Europe or email+Amazon in the US. Default customer support / payment / communications method.

    New to the site, big vision, many questions..

    What climate are you in? Is your attic finished? I’d be cautious about putting putting a POE switch in an unfinished attic for both overheating and dust reasons. What is your budget? Are you planning to do all the work yourself or have someone do parts for you?

    Dahua NVR HTTPS certificate is not valid

    Certificates have expiration dates, did you check that? Is this in Windows or Chrome? Chrome has its own certificate trust store.

    New planned NVR setup, is this possible - suggestion requested

    If you have power available at the remote site, I’d recommend using that. 150m is very far to run Ethernet, and you’d need to provide power for the switch and all 4 cameras over it. You’d need remote power to operate the wireless bridge recommended above. If you’re ok running cable in conduit...

    looking for options for enabling remote access for CGNAT fiber connection

    ZeroTier relies on the device you're accessing being online and running the ZeroTier software unless you're setting it up as a proxy. Do you have a plan for what to do if anything goes wrong with the ZeroTier host (like a failed update)? Would it be possible to configure ZeroTier on multiple...

    Ubiquiti P2P setup for passing standard LAN and IPC LAN?

    I think it's a tradeoff between how much infrastructure you want to put per camera, per building. If you have 5+ outbuildings each of which has a value of say $3000 and needs 2 cameras to cover it, installing a nanoStation in each building with PoE switch or injectors and 2 cameras gets very...

    Fiber to detached workshop options

    If you're buying your fiber from fs.com their transceivers are usually around $12 so you might save a few $ sourcing elsewhere but you save on shipping and it's all on one order to aid in tracking you've picked the right types.

    Ubiquiti P2P setup for passing standard LAN and IPC LAN?

    Depending on the layout of the outbuildings, would it be simpler to have some of the cameras connect via wifi to an SSID on the 10.7.83.x network? You might also find it easier to put a 16+ port switch if you can find one cheap at the outbuilding and just configure 8 or more of them for camera...

    Challenging Network Issue - Cameras going offline randomly

    The only way to identify common causes is to be systematic in documenting the issue when it happens. I'd suggest labelling all of the cameras on your diagram with the IP addresses of them. (Could be only the last part to save space if you want so 192.168.0.122 becomes "122"). When any camera go...

    Will airMAX NanoStation M5 work with airMAX NanoStation M5 loco?

    From the specs: INS-8023AF-O takes in 48V and puts out 18V, .7A it is 300g and does not mention Gigabit anywhere. INS-3AF-O-G takes in 48V and puts out 24V, .5A passive PoE, it is 90g and does specify Gigabit. Those seem like pretty clear differences to me.

    Network Congestion

    Has anyone set cameras to transmit over UDP? That seems much more suitable for a streaming use case than TCP. You're not going to get it everywhere in your house, but having an 802.11ax network is now much cheaper and higher performance than what you would see with g or n, and is not a...
