LPR setup help

I'm going to get a 7 series cam later, but for now I'm debating grabbing either the B58IR-Z4E S3 or the B54IR-ZE S3. I'm going to use it to test if I can grab plates at the T intersection I have, but will mainly be capturing people as they walk by on the sidewalk.

Hence, IR at night, color during the day. The plate capturing is basically a bonus if I can do it. If it works, like I'm hoping, then I'll either grab a 7 series or a dedicated ANPR.

Basically a $70 difference, but I'm leaning towards the 4k/8mp cam in hopes of getting better face captures. The sidewalk is approximately 50 feet from where the cam will be set.
 
Ended up grabbing a refurbished B74IR-Z4-AI, which should be here next week. Hoping to get a nice enough day to put it up and see how it works.

Main function will be capturing faces from the sidewalk about 50 feet away, and a extra bonus if it can also capture plates from the 60-80 foot area.

Before I put this cam up though, I'm going to run a temp line to my garage door and see how it looks covering my driveway/sidewalk for face detection, and bonus if it captures plates.
If it can cover the area well, I may grab another one next year as a replacement to the 4k color I have now, and use the 4k color as an extra cam on the side of my house.
 
I'm sure if the distances and angle works out you'll be fine during the day.

At night though, unless you havbe a shit ton of light, running IR you will have to choose between faces and plates

Yep... I do have quite a bit of light, and I'm bugging my city council representative in putting a bigger/brighter light on the light pole in front of my house. They already put a bigger/brighter bulb at the STOP sign. That will help quite a bit for night captures.

But, with this cam aimed at the T-intersection, I'll be prioritizing face captures during the night. If I grab another this coming spring for the other direction, that will be face capture priority.
I'm also planning on grabbing a triple lens cam for what I hope will be driveway--mailbox--road/vehicle capture. It'll be interesting to see if that works like I'm hoping.

Not to get too technical, but:

"The British ton is the long ton, which is 2240 pounds, and the U.S. ton is the short ton which is 2000 pounds.

Both tons are actually defined in the same way. 1 ton is equal to 20 hundredweight. It is just the definition of the hundredweight that differs between countries. In the U.S. there are 100 pounds in the hundredweight, and in Britain there are 112 pounds in the hundredweight. This causes the actual weight of the ton to differ between countries.

To distinguish between the two tons, the smaller U.S. ton is called short, while the larger British ton is called long.

There is also an third type of ton called the metric ton, equal to 1000 kilograms, or approximately 2204 pounds. The metric ton is officially called tonne. The SI standard calls it tonne, but the U.S. Government recommends calling it metric ton." (from onlinelineconversion.com)

So what does that mean for light, as per IPCAMTALK Technical Terminology?

Well, how much light is being referred to? It depends on where you are:

If you are in the US, then a Ton of Light (Short-Ton of light) = 2000 lumens.
If you are in Britan, then a Ton of Light (Long-Ton of light) = 2240 lumens.
If you are in any of the places that use the metric system, then a Ton of Light (Tonne, of Metric Ton) = 2204 lumens.

Now a Shit Ton of light is 10x (per IPCAMTALK Technical Terms). So 20000, 22400, or 22040 respectively.

Can you guess what a Mega-Shit Ton of light is?

Tested the 742 cam with my temporary cable and sat it on the back of my car. lol.. Zoomed all the way in, I'll definitely be able to capture face and license plates during the day from about 70 feet. At night? Priority is capturing face, but I think I'll get lucky and be able to capture plates occasionally.

I'm going for color 24/7, which I'm pretty sure I can get face detection at about 50 feet. If the city puts in a bigger/brighter bulb in the street lamp, I'll definitely be able to go color 24/7, since the street lamp is right at the capture point for face detection, and vehicles going by.

Hope to get it up this week. We shall see.

There are a few extra settings etc I'm having to dial in on this as well. If this works like I hope, I might purchase another 7 series for garage/driveway overview looking right just for the face detection captures. Overkill most likely, but I like/want the auto face capture. Though I probably could do that on the 608NVR and use the current 4k cam I have up. Hmmmm...

I will definitely get the triple cam for garage/driveway/mailbox captures this spring. I'm not sure whether I'll replace the 4k cam up there right now, or add the triple cam. I already have 5 cams over the garage lol
