Setting up POE Cisco 3750 for camera network

So, finally picked up a few cameras, and a cisco 10/100 POE switch catalyst 3750. Reset the switch and am trying to get my little network going.
 
I have been having trouble connecting directly to the switch using the GUI. I configured the interface (vlan1) to 10.4.120.106 (temporarily) and subnet to default 255.0.0.0. I could not connect my computer to the switch.
 
Then figure out that PC and switch were on different subnet. Changed subnet of switch to be same as PC. Now i can access the internet through the switch. I have a network cable that goes down to our house switch (connected to internet), one from PC to 3750 switch, and one camera plugged in to the 3750 currently.
 
I can't connect to the 3750 GUI to manage it. I can't connect to the camera. I am using the default camera IP for now.
 
This is my first time dealing with a cisco, managed switch so it has been a learning curve.
 
I believe the 3750 is defaulted to Auto for POE. When i first plugged in the camera, the port was amber. Now it is green, as are the other connections.
 
Thanks.

Got it. Funny when you type things out, your mind gets a different perspective. My gateway was not the same. Gateway, subnet all have to match. Tomorrow, I will start installing them.

Good news there newalarm!
 
Yup it is that blue cable that you needed.
 
The GUI is a bit slow. 
 
I do not recall talking to you as I had fallen asleep for a few minutes and wife woke me up.

So am still having trouble setting this up. After I disconnected switch and reinstalled it in my wiring closet (had to bench test it upstairs since my only computer with the serial D-9 connection is my old dell), i could not log into the cameras.
 
I plugged my windows laptop, and three cameras into the switch. The Hickvison SADP software did see the cameras and i was able to set them up. But when I try to log into each camera, it does not work as it did when i bench tested it friday. Seems weird that the hikvision software sees the cameras, but I can log in through web browser.
 
I checked IP on switch and it seems like it reset itself to default. Not sure why. I am going to download more literature on this switch so I can read up. I think my gateway is still wrong, but it did not give me option to change that.
 
Also, I set up the cameras for static IPs. Is it better/easier to do a DHCP set up?

You have to write the configuration to the switch when you are done so it saves it when you unplug the switch.
 
Google configuring a Cisco 3750 basics (easier to read non Cisco documentation to do this). 
 
I use static IP addressing on my cameras.   You can do static mapping of the DHCP addresses too if you want.
 
I typically have been using Firefox for my cams.  I've been using Grandstream / Grandstream OS for the cameras and have Grandstream software which lets me see all of the cameras at once and lets me edit each one separately.   Thinking you mentioned some SADP software.

I'd suggest static for the cameras or at least pull the addresses assigned via DHCP out of the pool and reserve as you go, but I'd probably just pick a block of 50 addresses and then set them aside.

I finally got the switch settings set properly and saved with Pete's help. I may have wiring issues. I got one camera up last night, but then it went out again and I could no longer log in to it. I may have a wiring issue. I was using a new (to me) patch panel and i believe it was wired for 568A. So wires was B on one end and A on the other. I will use a continuity tester to verify.
 
I rewired on another patch panel, and my Ethernet tester is showing proper wiring.

@newalarm is starting with 3 POE cameras.  We have a base of a network but redoing it and documenting it.  Concurrently new alarm is building a ZM box.
 
First piece will be to shrink down the size of the network to something a bit easier to manage.
 
1 - 254 devices  - 255.255.255.0
2 - 126 devices (is what I use) - 255.255.255.128 - I am currently at over 100 devices on main subnet here.
3 - 62 devices - 255.255.255.192
4 - 30 devices - 255.255.255.224
 
DHCP scope of how many devices.  Here have multiple subnets but keep the DHCP scope small.

I use a 255.255.255.0 mask, and have probably around 50 addressable devices. My DHCP pool is set to a block of 50 and used for DHCP devices only (e.g. phones, tablets). I have (2) DHCP reservations (static address in the DHCP pool via MAC) because those 2 devices do not allow the user to specify a static IP on them manually. All other devices on my network at manually entered and recorded (using address space outside of the DHCP range).

Yeah here keep the DHCP scope down a bit.  
 
Phone and tablets are off unless I am using them.  I use DHCP reservations today for HDHomerun devices and a couple of the HP in wall managed switches (only use two of these today).
 
Main subnet is primarily used.  That said I am using multiple LAN's off of the firewall connecting to two ISP connections with this stuff now going multiple managed / unmanaged switches (POE is in there too).
 
So here to help new alarm some and might as well post here on the beginning pieces of a home network infrastructure and fill in the blanks drawings.
 
The above noted open to suggestions to newalarm as we build this picture.
 
1 - base network infrastructure IP address stuff
2 - Dell server will be utilized for CCTV NVR
3 - 3 Hikvision cameras POE connected to 3750
4 - Cisco 3750
5 - combo router to ISP (I have no idea what this is)
 
 

 
 
 
 
 

so my home network subnet is on 255.255.255.0
 
If I use a second subnet of 255.255.255.192 for the security camera system, will i be able to connect a computer that is on the home network if the two switches are connected? Or do I need to match the PCs subnet to the security camera network.

For the time bean you will not be using a separate  / second subnet for your cameras.  Baby steps here.  Flat network.
 
What two switches?
 
Ok so we start with a base subnet mask of 255.255.255.0 which provides you with the option of 254 devices.  It is the default but really too large for a typical home network.
 
Let us start with your combination modem/router/switch/AP
 
What brand and model number are you using?
 
Next we revisit the configuration of this device first.

The router/gateway Linksys WRT45GS username and password are being requested by http://10.0.0.1. The site says: "level_15_access"s on 192.168.0.1, subnet 255.255.255.0 with DHCP. I think the only device that I assigned an IP to is the ELK. I need to check what that IP is. I don't know how to check for occupied IP addresses to see if there are conflicts, but if they are DHCP, when device gets back on, it will go to next IP.
 
Each camera is plugged into the POE switch. IP are 192.168.0.9X (1,2,3,4), with
Gateway 192.168.0.1
Subnet 255.255.255.0
 
a windows 10 pc is plugged into the POE switch via ethernet cable.
 
I intend to install cable between POE switch and house switch. When i originally bench tested, i had this cable plugged in.
 
POE switch is a 3750 10/100
IP 192.168.0.90
Gateway 192.168.0.1
Subnet 255.255.255.0
 
When i get home, i will check IP address of elk for conflicts. I will also double check all wiring as i picked up a tester from work.

The router/gateway is on 192.168.0.1, subnet 255.255.255.0 with DHCP
 
So you are keeping the subnet mask at /24 (255.255.255.0) for 254 devices. 
 
Do you think you will ever have this many devices on your network?
 
I would suggest making the subnet smaller along with a smaller DHCP scope.
 
Lets change the DHCP scope.  What is it?  Guesstimate how many devices will ever be using DHCP. 
 
Here I have HDHomerun devices which I assign DHCP addresses to via their mac address. 
 
Then decide where you want your devices to sit.
 
IE: switches / router between .1 and .10 maybe?
Server(s) between .11 and .20  (this could be your NVR, NAS, Media server ...whatever).
Cameras you have right now at .91 to .94
 
If you want give hostnames to the devices (whatever they are) that make sense to you.
 
PCs with static addresses can be high then put your DHCP scope high up (start maybe with 10 devices doing DHCP).

On DHCP, i guess not all stuff is on at one time. So we have DHCP Wifi 4-5 laptops, 2 tablets, 3-5 phones. DHCP total about 12 max. with a few extra for guests once in a while. around 15 worse case.
 
Wired ethernet DHCP: 2 TVs and one DVD, 2-3 pcs.
 
I could change subnet to 255.255.255.200 for wired and wireless DHCP. Would the elk be on this same network?
 
If the subnet for the security camera system is 255.255.255.90, can i access it (and elk if on different subnet) through the 255.255.255.200 network?
