Will IP address of CCTV camera change?
Discussion
I have just set up a CCTV camera and currently don’t have the internet fully. I set up the install with the internet on - not sure if that had any bearing. The camera - plugged straight from the computer was assigned an IP address and now that the internet is off and the computer has been off and on, the camera is still accessible on the same IP address.
Will it continue to work or will the IP address change?

The IP DHCP lease will be from the router, and as long as it stays on, it should hold the IP. If you're worried, you can (probably) setup a reservation to the MAC address for the camera, so even if it's off for ages, it'll pick up the same IP.
What router do you have, sure one of us can assist.

The camera was assigned an IP address by DHCP but since then i’ve not made any connection to internet and turned pc off a couple of times and is still working.
That set up was done using an EE Brightbox router that came with my broadband.
The camera set up will be installed tomorrow at a clients property where there no internet for 4 weeks. As a back up I am taking a TP Link TL-WR841N router - would it be better to connect into this router but with no internet connection as it will assign (and keep) the ip addresses?
Thanks

Not all routers use the exact same range of addresses, so your device might have one that is invalid. Many devices express their preference to keep an address, but the DHCP server will override if not suitable.
If you can use the router that’ll be in place when the Internet is provisioned, it’ll make life easier.

If you are setting it up on a clients property I would assign it a static IP direct with the camera. If you take a router to configure using DHCP then this could change once the client gets their internet installed and a different router which could have a different scope.
Also, if setting up a static IP, one the client has internet and a network installed, this will need to be on the same IP range as your static IP.

It’s frustrating because I am due to install tomorrow, currently in a hotel and when I tested the camera it wouldn’t connect on the previous IP address.
The pc hadn’t connected to the internet but it had discovered an available wireless network. Not sure if this would affect it?
I have done the same thing now - found the new IP address using DHCP and turned off my WiFi - despite turning pc on and off a few times this is still finding the camera with the same IP address.
I don’t understand why, if the pc doesn’t connect to the internet, it ever has a need to change that IP address??? I’m concerned that I’ll set it up tomorrow, leave, and in a day or two it’ll stop working.
I’ve read up on Static IP addresses and I’m sure that this is the way forward but it is currently too complicated for me to do. I would like to think that I could connect the camera directly to the PC with no Internet or router and therefore not have to worry about the IP address changing. Is there an easy and simple way to achieve this?

Take a note of the MAC address, leave the camera on DHCP and ask the client to look in the DHCP list and then find the IP the camera is on. Then ask the customer to set a reservation for it. Don't set a static IP for a network/ subnet that could well change in the near future... You'll end up having to go back which will be a headache.

It is all down to what is configured on the device which assigns out the IP address, which in this case is the router for a guess.
DHCP IP's will have a lease on them which expire for example after 24hrs, at that point generally what happens is the lease is renewed for the same IP for another fixed period of time and repeated. So in general it will always get the same IP from the DHCP server, unless everything is switched off for a long period of time so then chances are it may get a different IP.
You can as suggested modify the DHCP IP range restrict down, however this may affect other devices so you will find many others will not obtain an IP address if you limited it to one IP.
You could setup to assign a specific IP via DHCP to a specifc MAC address as mentioned, so you give the MAC address of the device to the DHCP server and say give it this IP address each time so it becomes static because of the config.
The easiest is a static IP though, you need to find the network range from the DHCP server e.g 192.168.x.x and choose an IP not in use and enter this and the subnet mask and default gateway on the device manually.
The internet or computer going on and off will have no impact on the IP, the computer would only impact this if it is the DHCP server

Why are you doing this supposedly as a pro when you haven’t a clue what you are doing?
If the client gets turned over and the camera fails to perform do you hold efficacy insurance or professional indemnity insurance?
Is the client aware you are not suitably qualified or competant for this task?
Have you properly taken into consideration and made the appropriate measures that your camera isn’t capable of being used in a pivot attack on your clients network?
A post like this is equivelant to a garage mechanic going on to a cookery forum and saying “ I’ve taken on a paid job starting tomorrow to do an engine rebuild on a cayenne, what does the oily bit next to the spinny thing do?”

I'm sure these were the questions on everyone's lips.
