Is Gigabit Poe Needed For Ip Cameras
Are there any network cameras, in the security/surveillance market place, that offer a ten/100/thousand Ethernet connection or are all 10/100? My question also leads to another one.
What good is a 10/100/1000 port on the POE switch if the photographic camera is 10/100?

The Axis P1428-E does, see excerpt of data sail:
There certainly may be others. I've never done a thorough search for this every bit generally Gig is non needed for IP cameras (e.thousand., even the Avigilon 7K / 30MP camera uses 100Mb/s only).
Related, there is such a thing called Industrial GigE cameras, dissimilar space than video surveillance.

Just to add, GigE cameras typically support uncompressed raw output, hence the need for 10x bandwidth.

well the most i accept ever had 1 photographic camera was 120Mbs
but and so again the camera was likewise functioning as a multi view web server as well with 4 other cameras streams mounted to the photographic camera
but information technology was likewise a $1500 camera with special firmware
guess if you had coin to throw at a custom chore the cameras hardware would exist able to handle it?

"What skilful is a x/100/1000 port on the POE switch if the camera is x/100?"
POE switches aren't just congenital for cameras. one would benefit from using a POE powered Gig Port when Connecting to a POE powered AP.

Gigabit sometimes brings unneeded complexity when dealing with PoE, equally PoE via Injection, or Manner B uses the unused pairs. Gig uses all pairs, and so in that location are no unused pairs. If you had a gig switch and a standard injector, information technology wouldn't piece of work.
Now at that place are gigabit and 802.3at uniform injectors, but be aware for older equipment.
I was recently looking for an industrial PoE switch with gig copper uplinks and ten/100 PoE ports. Very hard to find. Virtually had gig on all, or were ten/100 on all.

Not sure what you mean, equally I do this all the time.
Surveillance cameras, with very few exceptions (the p1428-eastward and Eddie'south classified SuperCam), have 100Mb interfaces, and then they naturally are using merely 1236; and since the injector injects on 4578, everything works fine.

haha no not classified merely I did sign a NDA for sure parts of the development work on it.
what I tin say is it involved using the cameras and the congenital in storage of an entire system (say 64 cameras) with each camera's storage linked to each other to grade a saleable/expandable deject or local deject organisation.
it was a neat idea merely non enough backing into it. to many china cams flooding the market to go far worth while for investors.

Only if your cameras are using GbE equally well. Fe photographic camera, port falls back to FE spec, mode B injector works fine.

I thought the answer was obvious on this merely it has not been mentioned and then maybe I am wrong:
A single 2-5MP camera might only need two-10Mbps simply allow's say you have twenty cameras that each needs 6Mbps and then the arrangement needs 120Mbps. So the port from the switch to the NVR/VMS has to be gigabit and hence yous volition demand a full gigabit switch (since non many switches have only 1 gigabit port and the rest are but ethernet).
Or am I missing something?

Harris,
That's not the instance.
Although it can be used for the backhaul, there "are" plenty of switches that have two-4 ports that are Gig ports and the rest that are 10/100.
These switches are built to fit many applications. So any Loftier Bandwidth POE powered device. ex. Wireless APs.

Undisclosed 3,
I do non disagree and I knew someone would postal service that there are switches with a few gigabit ports and the rest are 10/100. Before posting though I had a very brief look at the Cisco 110 and 200 series and all x/100 switches did not include a gigabit port. Some of course include GBIC ports which tin exist "converted" to gigabit and used for the backhaul.
Anyhow my point was that sometimes yous do need at to the lowest degree i gigabit port on the switch.
Tin can you delight explain more on the below, not sure I understood what you meant and I am always curious to learn new things:

No conversion is necessary when using the 200-series combo ports for GigE. They "convert" to something else only when yous plug-in a GBIC.
The SF200-FP provides sufficient bandwidth for typical surviellience configurations, and can run at full speed on all ports at the same time.

Nearly all IP cameras will never come shut to 100 Mbps so a gigabit port isn't needed for the port that the camera is plugged into. The max we set our cameras to is 4 Mbps.
Yet, IMO, the switch should always have atleast 2 Gigabit uplink ports. One that is connected to the NVR and the other that is connected to the router. The reason those should be gigabit rated is because it takes all the combined traffic from all IP cameras and sends them through one port, and in this case, all the combined traffic could be more than than 100 Mbps.
For modest four aqueduct systems, and probably even an viii aqueduct system, gigabit uplink ports probably arent needed, but its skillful to accept them anyways.

The switch should always have at least 2 Gigabit uplink ports. One that is connected to the NVR and the other that is connected to the router.
Will this setup have less lag than just connecting the NVR and the Poe switch directly to the router?

Why one connected to the router? Assuming a POE NVR, isn't information technology just every bit fast and twice as safe to connect the router to the LAN side of the NVR?

Admittedly, assuming its a POE NVR y'all wont really need a seperate switch at all. Also, most all of what I accept seen on POE NVR'southward, the primary Lan connections on the NVR'southward are gigabit rated.

Okay, one thing nobody'due south mentioned yet is that all-gigabit switches tend to have a much stronger backplane (aka "fabric", aka switching chapters) than their 10/100 cousins.
Example:
- Cisco SF300-24P (24 10/100 802.11af ports, four GbE ports, two mini-GBIC slots) lists at 12.8Gbps switching chapters.
- Cisco SG300-28P (24 GbE 802.11af ports, four not-powered GbE ports, ii mini-GBIC slots) lists 56Gbps.
If you're stacking a lot of loftier-traffic cameras and maybe running your NVR to iSCSI storage, you're going to come a lot closer to the maximum of what the FE switch can handle. Might never hit information technology, but personally, I'd rather accept all that headroom.
From our usual local retailer, it's about a 50% premium for the SG model ($780, vs $530 for the SF version).

About switches are not-blocking these days, significant that they provide full line charge per unit switching capability for all ports, full-duplex at the same time.
These switches are a good instance, here'due south the Fe model:
24 x 100 Mbps = ii.4 Gbps ten two (full duplex) = 4.viii Gbps
4 ten thou Gbps = four Gbps x 2 (full duplex) = 8.0 Gbps
Total 12.8 Gbps, exactly the spec.
As for headroom, one prissy thing about photographic camera networks is that it'south basically a 1 way street, so you always have 2.4 Gbps headroom, or one-half the photographic camera bandwidth back.

This is an old chat, just I thought I'd add something that hasn't been discussed: Total Switching Chapters. This is the corporeality of bandwidth that the switch can process through all of its ports simultaneously. Well-nigh budget-friendly switches (especially those marketed to the camera world) do non provide enough total switching capacity to run all ports at maximum throughput simultaneously. Unlike connecting other devices such as computers, cameras are streaming at full blast the whole time they are connected. Since your average camera volition max out a 10/100 port pretty readily, y'all need a switch capable of handling that capacity beyond equally many ports equally you have continued at any given time. If you plan on using 4 or five ports on an eight port 10/100 switch, you won't take much issue. If you program on using 7 or 8 ports on the aforementioned switch, you will have serious functioning issues. Simply swapping out for a gigabit switch will solve the problem. Even though your cameras will withal connect at ten/100, the actress switching capacity on the switch will make all the difference.
