PoE NVR vs NVR with External PoE Switch: A Comprehensive Comparison

hi Luke Raymond from an access security systems today we're going to cover a topic which is a major major issue for many many installs and is actually the part of a video surveillance install which can get you into a lot of trouble so we're going to take a look at bandwidth why you're going to choose the type of switch you're going to choose and is it going to be on board in the NVR or offboard let's take a [Music] look to start with most nvrs today come with an onboard built-in switch this switch is designed to get your IP cameras and power them with Poe here you have a built-in switch for eight ports each one of these ports is a 10100 Port which means it has a 100 megabit maximum of bandwidth and provides power and data over the Cat 5 cable to the cameras it additionally has another Port this is the network interface port that generally speaking is going to be a 1 gabit Port well this 1 gbit Port then goes to the router and allows all of the data from all of these cameras to be multiplexed onto this individual cable so what does all of this mean well from the point of view of bandwidth it has to do with how much data a camera pulls on an individual Cat 5 cable versus how many cameras you have in the system so for example let's use size think of this as the amount of data that a single camera pulls this is not a lot of bandwidth so a 10100 Network a 100 megabit maximum network is more than enough for this let's think of the 10100 Network as the edge of this water bottle this is enough data that it can fit on that 101w network no problem whatsoever but what happens if you take this and you Multiplex eight of these cameras or 16 of these cameras or even bigger applications where you have 64200 cameras well when you take this amount of data and you multiply it by 16 for example all of a sudden you have something much much bigger well this bandwidth it's too big it will not fit into this size of pipe if you will so what you have to do is you have to increase the size of the bandwidth what this means is let's say I take all eight cameras and it's this amount of data as long as the pipe the cable can handle the amount of data I'm pushing into it it should be fine that is the explanation of why each one of these ports are 10100 while the backbone Port is one gabit that's why we do it this way but there's another problem what about larger applications where I have multiple nvrs well let's say I had five nvrs each one is a 16 channel each individual 10100 Port is powering and pulling the data off of each individual camera and then there's a one gigabit Port taking all 16 of those cameras and sending them back to a centralized location well what if I had four or five nvrs all with 16 cameras that would be five ports five cat 6 cables in this case coming back to a centralized switch well that centralized switch needs to be powerful each one of the ports on that switch needs to have at least one gabit and it then needs to be able to take all those five cables with one gabit each and put them all together and send them over a single cable back to your server well that's when an external switch comes into play external switches can have for example 10 100 ports they can also have 1 GB cable ports or they can also have what we call combo ports now this is a perfect example when we're dealing with 10100 networks Cat 5 cable is more than enough if we want to use a copper cable to send data at 1 gigabit cat 6 is a great choice and we often times will have backbone ports of 1 gbit for this but what happens if we want to pass the 328 ft which is the i e standard for data over a coper cable what if we want to past 328 ft well I can go 328 ft on a cat 5 or cat 6 cable for from this switch to another switch then another 328 ft from that switch to another switch basically 100 m each jump but this becomes unrealistic in many applications where we need to go really long distances this is where these backbone ports come into play these backbone ports are called sfps small form factor pluga bles we sell SFP modules that you can put into here and essentially it allows you to then have a different media to send your data large amounts of data over long distances in these case cases often times we will sell you an SFP which is good for fiber optic cables whereas copper cables as per the Apple Triple E you can go 100 m 328 ft on a cat 5 or cat 6 without losing any data when it comes to fiber there are other options I can go 300 M or 1,000 ft on standard 62.5 Micron fiber optic multimode cable that's the orange jacket if I want to go farther than that I can use the blue jacketed 50 Micron cable to go 2,000 ft or 600 M as a standard when I want to go longer than that I can actually use the yellow jacketed single mode fiber which goes kilometers and kilometers and kilometers if I want it to whatever media you're choosing having an onboard switch is generally speaking a better choice for smaller applications but once you start getting into these larger applications and you're going to need a centralized more powerful switch often times managed layer 2 or layer three switches with combo ports such as the SFP modules to be able to connect them all together over longer distances is a better choice here at in Access security systems we are a professional security company with Professional Security products and we specialize in design for our customers what this means is you can always rely on us to walk through your application with you and design the entire job not just the cameras and the access control but even the networking behind it that's going to tie the whole thing together which is truth be told the most important part of any application we can help you design and pick the right choices for your products if you have any questions or comments please leave them in the section below we're more than happy to reach out to you [Music] cheers
