I am looking at c.c.t.v. hard wired systems in the inner net.

they use the term channels,

I've looked at 7 glossery's for what channels are.

they don't include the term channels

some systems are 3, 5,8 12 channels
are more , better ?

It's how many cameras the system supports.

five channel system can record five cameras at a time ,simultaneously.

o.k. thanks

A five channel recorder sounds unusual though, but I guess it may exist. Usually they are 4, 8, 16, or 32.

I just picked a number out of the air .

Are you sure you don't want to go the IP cam route?

I admit there are tradeoffs, but if you don't mind the initial fumbling around to get IP cams set up, they are great.

I have not considered "I.P." what ever that is

with a 6 channel system do you have to buy 6 cards ? one for each camera

you connect IP cams to a router, like for your computer. each camera has an address like 192.168.1.12 and you get an NVR or use software on your computer, like Blue Iris.

I went that route and I'm very happy.

you route cat-5e to each camera and you can set it up to get the power over the cat-5e too.

IMHO, in 2018, IP cams are the way to go. Some disagree since there is some setup involved that takes some technical knowledge, but once set up, you can do lots of things, like I get text alerts when someone enters my front porch.

I got several like this... https://www.amazon.com/dp/B073...0IP4M-1026E%20(Black)

then record with this:

or the software like Blue Iris

Maybe you need a professional to advise you, after all that is the line lawyers use all the time.
Why not get some one who knows this category professionally rather than listening to a bunch of amateurs?
Didn't some supposedly brilliant lawyer here say {sic} "I hear a lot of advise here that is spectacularly wrong".
The IT area is no different.

not this shit again

Pro (since the mid eighties) chiming in.

You can buy a stand-alone DVR and some cameras that are either "HD-TVI" (there are other HD formats) or "IP".

I have a 3 year old DVR at home that does three formats; standard analog cameras up to 960H, HD-TVI cameras up to 2.1MP, and IP cameras up to 5 MP. I don't need anything else/better at this time. I have a couple IP cameras in the house and an HD-TVI auto focus camera outside.

You can run CAT-5 or CAT-6 cable for all types of cameras. If you are using analog type cameras, you simply use a balun at each end. I use a type of balun that provides power on a plug to the camera.

Some people find that the HD-TVI (or other HD analog format) systems are easier to deal with.

I apologize.
I wasn't intending to insult the advice here and say I'm better than anyone else.
I was merely mocking the advice the lawyers here (as-a-joke) always give to use them.
In addition it appears the OP could use some good on-site help in this case.
So sorry.

Just to add, it's my personal opinion that a 2.1MP camera (1080P) is the minimum resolution one should buy.

In some cases, such as a small defined coverage area or room, you can get by with 1.3MP.

No problem

These threads are tough because it is a very technical topic, and we never really know what the budget or intent of the system is. We don't know if he's using "home hobby $$$" or if he has more $$ to play with in, say, a well funded work environment. We don't know if he just wants to see what his dog is doing while he's at work, or if he's wiring up the security cams for a 24 hour Stop-N-Go in the crappy part of Tacoma, WA.

By the way, I did hire a professional for routing my Cat-5e cables in my existing house. He and his helper did in a few hours what would have taken me all weekend, plus he had the proper tools for fishing wires through walls etc. Several hundred $$ well spent, and I got the "media closet" that I always really wanted.

if 2.1 is the min.
what are the good one's
the better one's
and the much better numbers?

In making a camera decision you cannot just use pixel count as a basis for what is quality.
You should first determine the "scene" attributes > day/night, complexity, field of view in depth and width and apply it to a desired amount of resolution.
For example if your general area is 8 to 10 feet away in a bright area the requirements would be less than one where you need facial recognition at 75 feet in a less bright area.
At night the ability is even worse.
As far as a rule that you need a 2mp camera so a 4K camera is better might seem logical.
However, it would be in many scenarios but in other it could be worse or at best no real difference.
One should look at the desired requirements then match a camera to what is needed.
YMMV

No offense to bendable intended, but come on guys. You’re talking cat5/6 cable, IP vs. HD, NVR, Blue Iris, etc to the man that asked someone to copy, enlarge by 35%, and 3D print him a Casio watch.

Thread here.

Wireless out the box system or consult with a local installer.

I have a 4 year old Lorex 8 camera system (1080p HD Mp DVR) that is hardwired...that records all the channels in a continuous loop. after you buy the system you will need a monitor. Depending on where you put the cameras you might need extensions for some of the wires. The infrared lights on the cameras are really good.
About 6 months ago I broke down and figure out how to connect it to the internet so I could access the cameras while out of town... a real pain in the but to do... never could get it to connect to my lap top... but did get it on my phone... UNTIL lore decided to upgrade the AP on my phone.. now it won't. Have not taken the time to figure it out since it took about 6 hours to get the dern thing to connect before.
