Ok
Thank you for your help, I will try my luck with setting up IVS and see what happens

Before I start on the IVS should I be doing this on the cameras or on the NVR? I can see the option on the NVR but just want to make sure before I mess it all up

On the camera

Ok so I have attempted this as per the attached however when I stepped into the area I didn't receive any notification and I cannot see anything recorded. Do the settings look right?

yes it looks right.
Two things:
1- Lets not confuse IVS working with NVR recording. Two separate things that require separate investigations
2- As to IVS working, ideally you would be logged into the NVR or bvetter, SmartPSS and see if the IVS lines flashed Red indicating they are working.
Personally I would cover the area with a zig zag Tripwire in addition to the Intrusion box
Also, its quite dark and the camera is way too high, both will make it harder for IVS to see as well as make the whole 3D effect of IVS more tricky.
Example
The woman literally walked "Under" the IVS line without tripping it, the taller man tripped it. This is what I mean about 3D effect of IVS.
Zig zag tripwires work best IMHO and I usually put them inside an area outlined by an Intrusion box. Redundancy is good and its free!
IVS lines flashing red indicating a good trigger

How do you add the zig zag tripwire lines inside the box? If I add another rule the picture only shows the new zig zag lines and the intrusion box has disappeared.

Actually I just came out of the rules and went to live view and can see box the rules on the picture. Time to go for a walk and see if the lines turn red!

That was a massive fail as not a single line went red as I was walking through. This is what it currently looks like

As I stated earlier, that is part of the problem with that camera, especially its night performance, so coupled with that camera and a higher than ideal camera placement will result in issues.
Are you running auto/default settings or have you input a manual shutter speed like 1/60? That can have an impact.

It should be running the default setting as I not aware the manual shutter speed and not something I have touched.
So do you think with the way I have those lines, if I was to walk through in the day time, the lines would go red while testing?

Yes with enough light they should trigger.
On default you may be going thru as a ghost and that is why it isn't seeing you.
In terms of getting the most out of the camera, here is my "standard" post that many use as a start for dialing in day and night that helps get the clean captures and help the camera recognize people and cars.
Start with:
H264
8192 bitrate
CBR
15FPS
15 iframes
Every field of view is different, but I have found you need contrast to usually be 6-8 higher than the brightness number at night.
We want the ability to freeze frame capture a clean image from the video at night, and that is only done with a shutter of 1/60 or faster. At night, default/auto may be on 1/12s shutter or worse to make the image bright.
In my opinion, shutter (exposure) and gain are the two most important parameters and then base the others off of it. Shutter is more important than FPS. It is the shutter speed that prevents motion blur, not FPS. 15 FPS is more than enough for surveillance cameras as we are not producing Hollywood movies. Match iframes to FPS. 15FPS is all that is usually needed.
Many people do not realize there is manual shutter that lets you adjust shutter and gain and a shutter priority that only lets you adjust shutter speed but not gain. The higher the gain, the bigger the noise and see-through ghosting start to appear because the noise is amplified. Most people select shutter priority and run a faster shutter than they should because it is likely being done at 100 gain, so it is actually defeating their purpose of a faster shutter.
Go into shutter settings and change to manual shutter and start with custom shutter as ms and change to 0-8.3ms and gain 0-50 (night) and 0-4ms exposure and 0-30 gain (day)for starters. Auto could have a shutter speed of 100ms or more with a gain at 100 and shutter priority could result in gain up at 100 which will contribute to significant ghosting and that blinding white you will get from the infrared or white light.
Now what you will notice immediately at night is that your image gets A LOT darker. That faster the shutter, the more light that is needed. But it is a balance. The nice bright night static image results in Casper blur and ghost during motion LOL. What do we want, a nice static image or a clean image when there is motion introduced to the scene?
In the daytime, if it is still too bright, then drop the 4ms down to 3ms then 2ms, etc. You have to play with it for your field of view.
Then at night, if it is too dark, then start adding ms to the time. Go to 10ms, 12ms, etc. until you find what you feel is acceptable as an image. Then have someone walk around and see if you can get a clean shot. Try not to go above 16.67ms (but certainly not above 30ms) as that tends to be the point where blur starts to occur. Conversely, if it is still bright, then drop down in time to get a faster shutter.
You can also adjust brightness and contrast to improve the image. But try not to go above 70 for anything and try to have contrast be at least 7-10 digits higher than brightness.
You can also add some gain to brighten the image - but the higher the gain, the more ghosting you get. Some cameras can go to 70 or so before it is an issue and some can't go over 50.
But adjusting those two settings will have the biggest impact. The next one is noise reduction. Want to keep that as low as possible. Depending on the amount of light you have, you might be able to get down to 40 or so at night (again camera dependent) and 20-30 during the day, but take it as low as you can before it gets too noisy. Again this one is a balance as well. Too smooth and no noise can result in soft images and contribute to blur.
Do not use backlight features until you have exhausted every other parameter setting. And if you do have to use backlight, take it down as low as possible.
After every setting adjustment, have someone walk around outside and see if you can freeze-frame to get a clean image. If not, keep changing until you do. Clean motion pictures are what we are after, not a clean static image.
