Smart hub ip address setup tech info needed.

[Andy2315]

Hi. I have a customer, with a smart hub sh20a.

we have installed some ip cameras a while ago, stand alone to the DVR.

they then wanted to view them online from the phone. So set the equipment to be dhcp enabled and take their ip addresses from the router. The DVR seems to remain as a static ip address, but the cameras keep changing. I keep having to go back and set the camera ip address in the DVR for it to reconnect.

I have accessed the router settings and when you find the equipment in the list you can set it to use this ip address, then when saved says (static) next to it.

then after a few weeks it goes offline, I go back check DVR, and the ip addresses in the camera list have changed, I need to remove the 2 old ones then re add the new ones, normally drifted by 1 digit up. Check router again and the old ip addresses have gone, and new ones in the list not static.

i tried setting the addresses outside the address table, as you can with other routers where they remain static and not change. But this rendered them unfindable then.

any help from any tech bods would be most appreciated. Saves me going back numerous times to reset it all.

many thanks.

@Andy2315 The DHCP Static option should work ok, but as you are finding it is not holding, set them to static as before, note the dhcp values to use for the cameras and go into the DVR software and set them to fixed ip's that way.

Then you will have fixed static in the EE, and using fixed values within the DVR software, that should take care off them both.

Hi, thanks for the reply.
Done all that but the static ip address doesn’t stay static. It changes. So I need to keep going back and putting the new ip address into the DVR.
Also noticed on last trip it wouldn’t let me set a new static IP as it said it was in use. Looking through the list, the ip address was in twice by 2 different items!!
Cheers

@Andy2315 For your info. just seen the BT Smarthub2 get a new FW update today where i am working at present, as you have the EE equivalent would not be surprised that it also gets an update, you just never know what is going on with all these updates that are being put out and rapid at present. Below is the new BT Version so you can see.

Firmware version: v0.45.00.08028-BT

Firmware updated: 1-Apr-2025

Thank you, I’m going back up again tomorrow to set it all up again. That router is doing my tree in to be honest. Thinking of telling him to move to memory cards in the cameras.
They drop off his DVR, but he can still access them via browser from his phone via P2P , so even though it’s not on his DVR, the footage can be dragged from camera memory card.
Never had this much trouble with a router, and I think it’s the first EE router I have come across though.

@Andy2315 Would try to make all the cameras and the DVR static IP addresses, that should give in theory the best result, but look closely at the network web interface for all, and pay attention to the mac's on each also.

If an IP cannot be made static, then something has connected previous and the EE Router knows about it, that is the reason that you cannot assign or make static, pick a range say 100, for the DVR then set the cameras at 101,102,103 etc. SAVE at the end, reboot the router and check that they are holding.

Hi

been up and taken the cameras off from accepting DHCP, set them to an ip address that was free next to the DVR ip address. Strange thing is the DVR was on set to accept DHCP and has never moved.

logged into router and there is a camera ip address assigned to 2 MAC addresses, how does that happen.

hopefully now, the system will remain stable and not keep changing addresses.

never had this much aggro with an ip setup.

@Andy2315 Do the cameras per chance have wireless and also an Ethernet port, if so then not unusual for the camera to have a mac for each port, and if so sounds like the EE Router has managed to find out that there are two. If not then the DHCP on the router has really got messed up with it's internal memory when it stores the last assigned IP/Mac when request for IP is made from the camera's.

Hi, just standard ip cameras, no WiFi option.
He went wired for cost and reliability. But his router must be well and truly confused.
Hopefully turning off the cameras dhcp and setting them on their own address will be the end of it. So much for the use the same address toggle!!
Cheers for your input, hopefully not back for other ideas within the next week.
