Welcome to the land of video surveillance lunatics.
My standard welcome -
Start out by looking in the WiKi in the blue bar at the top of the page. There's a ton of very useful information in there and it needs to be viewed on a computer, not a phone or tablet. The Cliff Notes will be of particular interest although the camera models listed there are a generation old at this point. The best way to determine what kind of camera you need in each location and where each location should really be is to buy one varifocal camera first and set up a test stand for it that can be easily moved around. Test using that, viewing using the web interface of the camera, during the day and at night. Have someone walk around behaving like a miscreant and see if you can identify them. There is also information for choosing hardware and securing the system along with a whole bunch of other good stuff.
Don't chase megapixels unless you have a really BIG budget. General rule of thumb is that a 4MP camera will easily outperform an 8MP camera when they both have the same sensor size. Reason being that there are twice as many pixels in the 8MP versus the 4MP. This results in only half the available light getting to each pixel in an 8MP that a pixel in the 4MP "sees".
A dedicated PC doesn't need to be either expensive to purchase or to run. A used business class machine can be had from eBay and various other sources. The advances made in Blue Iris make it easily possible to run a fairly large system on relatively inexpensive hardware which also makes power consumption low, as in under 50 watts in many cases. The biggest expenses turn out to be hard drives for storing video and a PoE switch to power the cameras and, of course, the cameras themselves.
Three rules
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.
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. 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. I say this twice because far too many people get caught by marketing with night time still shots and are disappointed when they get the cameras and have useless, blurred, night time motion video. 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.

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. Hikvision also makes a similar line of 1/1.8" sensor cameras that compare very well with the Dahua equivalents.

Welcome to the forum....It's clear now, why these guys recommend the 5442 series cameras. I finally bought a IPC-T5442TM-AS-LED 2.8mm camera. It came with a Torx wrench, and you can tighten the turret in place in the "metal" housing, to keep prying hands from redirecting the camera. You can "hear" the built in audio right outta the box, with no seperate audio jack connections...How nice is that? Very Fn Nice! I have learned the hard way by buying less expensive camera's and people can reach up and turn the cameras. and that they say they have a built in Mic, but you have to do additional wiring to get audio in some cases.
So some of these recommendations, come from their own trial and error......saving you lots of trial and error.....maybe.....Although some of the less expensive camera's will work in some areas....
