Start out by reading the
Wiki in the blue bar at the top of the page on a real computer, not a tablet or phone. That will get you "grounded" in how to set up a video surveillance system that actually works. Wyse, and all the other plug-n-play cameras, are not really capable of doing what your goals are.
Do not chase megapixels, chase sensor size. There is a direct relationship between resolution and the size of a sensor to produce good video in low or no light situations. Remember these sensors are shown in fractional sizes so they are inversely proportional, IE a 1/3" sensor is smaller than a 1/2.7" sensor. They are also a fraction of the size of the sensors used in cell phones and especially in DSLR cameras.
The next thing is lens size, focal length. Wyse, and all of those cameras, always offer wide, sweeping, views that look impressive. The problem is that all detail is lost to get that wide view. A camera with a 2.8mm lens will not produce a useable identification shot unless the subject is within 15 feet or less of the camera, and that 15 feet is being generous. It's more like 11 feet or so.
The next problem is mounting height of the camera. A camera needs to be o higher than about 7 and a half feet to produce good facial identification. Mounting them higher results in nice shots of the top of heads. That can be mitigated if the camera is higher than 7-1/2 feet and further away bt that requires a longer focal length.
The smartest thing to do is to buy a good varifocal camera, set it up in a test rig, use the built in GUI of the camera and test each proposed location. That allows you to find the right focal length, there's a converter in the Wiki, and also lets you become familiar with all the adjustments required to maximize the performance of the camera. Wyse, and all of those, keep things on automatic which is not optimal and rarely, if ever, actually produces the quality level that a camera is capable of.
In terms of connecting back to a remote location you can use a dedicated, encrypted, RF link like the Ubiquity Nano Station Loco M5. It is a dedicated point-to-point link and will span several kilometers if needed and will easily handle a half dozen, or more cameras simultaneously.
The three basic rules of video surveillance cameras-
Rule #1 - Cameras multiply like rabbits.
Rule #2 - Cameras are more addictive than drugs.
Rule #3 - You never have enough cameras.
Quick guide -
The smaller the lux number the better the low light performance. 0.002 is better than 0.02
The smaller the "F" of the lens the better the low light performance. F1.4 is better than F1.8
The larger the sensor the better the low light performance. 1/1.8" is better (bigger) than 1/2.7"
The higher the megapixels for the same size sensor the worse the low light performance. A 4MP camera with a 1/1.8" sensor will perform better than a 8MP camera with that same 1/1.8" sensor.
Disclaimer - These sizes are what the manufacturers advertise and may, or may not, be the true size of the sensor in the camera.
720P - 1/3" = .333"
2MP - 1/2.8" = .357" (think a .38 caliber bullet)
4MP - 1/1.8" = .555" (bigger than a .50 caliber bullet or ball)
8MP - 1/1.2" = .833" (bigger than a 20mm chain gun round)
Focal length, lens size, is another critical element in camera selection. A 2.8mm lens will produce a nice wide view but will be useless for identification at distances greater than abut 10 or 15 feet.

Don't believe all the marketing hype no matter who makes the camera. Don't believe those nice night time captures they all use. Look for videos, with motion, to determine low light performance. Any camera can be made to "see" color at night if the exposure time is long enough, as in half a second or longer. Rule of thumb, the shutter speed needs to be at 1/60 or higher to get night video without blurring.
Read the reviews here, most include both still shots and video.
Avoid Reolink, Foscam, SV3C, Nest, and all the other consumer grade cameras. They all struggle mightily at night and never get anything useful on video. Here's a link to a whole thread debunking Reolink in particular.

Executive Summary: DO NOT be a sheep. Ask what a reviewer can be missing, ask if a reviewer is using hype words to sell the cheapest product. Test your cameras and kits right away. Just do a bench test. Test real world conditions. Test moving suspects. Test at night, test at day. Use a test rig...

Avoid WiFi cameras, even doorbell cameras. WiFi is not designed for the constant, 24/7, load of video that a surveillance camera produces. At best, with two cameras on WiFi, they will still experience dropouts multiple times daily. Murphy's Law says that will happen at the worst possible moment.
Lens size, focal length, is another critical factor. Many people like the wide, sweeping, views of a 2.8mm lens but be aware that identification is problematic with a lens that wide. Keep in mind that it may take two cameras, or more, to provide the coverage you need or desire. Another factor that effects view angles is the sensor size. Typically larger sensors will have a larger field of view in any given lens size.
The 5442 series of cameras by Dahua is the current "king of the hill". They are 4MP and capable of color with some ambient light at night. The 2231 series is a less expensive alternative in 2MP and does not have audio capabilities, no built in microphone, but is easier on the budget. The 3241T-ZAS has similar spcs as the 2231 and has audio. There are also cameras available from the
IPCT Store right here on the forum and from Nelly's Security who has a thread in the vendors section.
