4 ethernet cables through outside wall

Having done a bit of research this afternoon, I'm wondering whether the cams actually have to connect directly to the NVR, or whether it will find them as long as they connect to my network. That would open up other possibilities, as I could then use a Powerline adaptor in my garage to have a camera on the outside of that too, and still have it visible to the NVR via my home network. So I'd want my NVR in my house, connected to the router by ethernet, 2 or 3 cams on the outside of my house connected to the NVR by ethernet through a hole in the wall, and 1 more cam on the garage connected to the network via ethernet provided by a Powerline adaptor, but hopefully still visible to (and controllable by) my NVR.

Is this ok or am I missing something? (Is this all about dynamic v static IP addresses, or is that irrelevant?

If they are true IP camera's then they can connect to any part of your network. The proprietary ones don't usually use CAT5...

Correct. IP cams will be found by your NVR as long as they are on the same subnet. With hikvision, you have the SADP software which locates the cams and allows you to configure their ip address, which then allows the NVR to locate them. Typically, an NVR with PoE ports is usually more expensive than one without. However, you then need to factor in the price of a PoE switch.

The other thing to keep in mind is the number of channels and the maximum bandwidth your NVR supports over ethernet. I forget the terminology, but this will dictate how many IP cams it can support.

IIRC 3MP/HIKVision cameras tend to use about 5mb/s max each, with the 4 camera DVR's having a maximum bandwidth of about 40mb/s.

The DVR's are usually sold with a camera limit that is a lot lower than the bandwidth limit.

One of my friends is currently having fun with setting up some CCTV system to cover his house and outbuildings.

I have a cctv system that uses POE on back order for a few weeks now. I also wondered about how big hole to allow to cable and I assume plugs to go through brick built garage. My main reason I am getting it is last month had car whilst stationary hit and driver drove off without reporting it. So I going to get twin camera set up with 4MP HD cameras

I just going to hook the NVR to a tplink homeplug which I have setup in garage ready for cctv and works fine extending ethernet and wireless. I already have 2 of these homeplugs ariound house to cover all dead areas

I crimped the RJ45 plugs on after feeding the cables through. This allows for a smaller hole to be drilled. Buy a decent crimp tool and it's not too difficult to do.

While we're giving advice - make sure you use 'exterior' cat5 - it is coated and resistant to UV light. Either that or put it in conduit.

They're never as secure or long lasting as pre-made cables though.

Nilrem

Although if they're not unplugged on a regular basis they'll last a very long time.
It's the number of insertions/removals that affects the life of most cables as the stresses at the joints results in them failing over time, if it's a permanent/semi permanent installation you'll probably never notice the difference.

I've got some here that I did as my first attempt at making my own connections 10+ years ago and they're still fine.

Totally agree with that. Never had an issue with any of mine, though always find when crimping the connectors on, now and again one will not work correctly, and needs to be recrimped. Standing on a ladder in the cold or the sun is usually not the ideal place to be trying to insert 8 tiny little wires into a plug

A cheap tester (~£3 from amazon/ebay) can save you lots of aggro and you know you've done the job right straight away.
