Welcome!
Good thing you found this site before buying the Reolinks. See thread below on all the people that are not happy with their performance.
You need to identify the areas you want to cover and pick a camera designed to cover that distance. In some instances, it may be a 2MP or 4MP that is the right camera. DO NOT CHASE MP!!!
It is why we recommend to purchase one good varifocal and test it at all the proposed locations day and night to figure out the correct focal lengths and cams.
A few other tips....It is simple LOL do not chase MP - do not buy a 4MP camera that is anything smaller than a 1/1.8" sensor. Do not buy a 2MP camera that is anything smaller than a 1/2.8" sensor. Do not buy a 4K (8MP) camera on anything smaller than a 1/1.2" sensor.
Unfortunately, most 4k (8MP) cams are on the same sensor as a 2MP and thus the 2MP will kick its butt all night long as the 4k will need 4 times the light than the 2MP... 4k will do very poor at night unless you have stadium quality lighting (well a lot of lighting LOL). Starlight, ColorVu, Full Color, etc. are simply marketing terms, so don't be sold on those names.
To identify someone with the wide-angle 2.8mm lens that most people opt for, someone would have to be within 13 feet of the camera, but realistically within 10 feet after you dial it in to your settings.
My neighbor was bragging to me how he only needed his four 2.8mm fixed lens 4k cams to see his entire property and the street and his whole backyard. His car was sitting in the driveway practically touching the garage door and his video quality was useless to ID the perp not even 10 feet away.
Meanwhile my 2MP varifocal optically zoomed 60 feet away to the public sidewalk provided the money shot to the police to get my neighbors all their stuff back. Nobody else had video that could provide anything useful, other than what time this motion blur ghost was at their car.
Here are my general distance recommendations, but switch out the Dahua 5442 series camera to the equivalent 2MP on the 1/2.8" sensor or equivalent Hikvision works as well. These cameras meet all your requirements.
- 5442 fixed lens 2.8mm - anything within 10 feet of camera OR as an overview camera
- 5442 ZE - varifocal - distances up to 40-50 feet (personally I wouldn't go past the 30 foot range but I like things closer)
- 5442 Z4E - anything up to 80-100 feet (personally I wouldn't go past 60 feet but I like things closer)
- 5241-Z12E - anything from 80 feet to almost 200 feet (personally I wouldn't go past 150 feet because I like things closer)
- 5241-Z12E - for a license plate cam that you would angle up the street to get plates up to about 175 feet away, or up to 220 with additional IR.
- 49225 PTZ - great auto-track PTZ and in conjunction with an NVR or Blue Iris and the cameras above that you can use as spotter cams to point the PTZ to the correct location to compliment the fixed cams.
You need to get the correct camera for the area trying to be covered. A wide angle 2.8mm to IDENTIFY someone 40 feet away is the wrong camera regardless of how good the camera is. A 2.8mm camera to IDENTIFY someone within 10 feet is a good choice OR it is an overview camera to see something happened but not be able to identify who.
One camera cannot be the be all, see all. Each one is selected for covering a specific area. Most of us here have different brands and types, from fixed cams, to varifocals, to PTZs, each one selected for it's primary purpose and to utilize the strength of that particular camera.
So you will need to identify the distance the camera would be from the activities you want to
IDENTIFY on and purchase the correct camera for that distance as an
optical zoom.
If you want to see things far away, you need optical zoom, digital zoom only works in the movies and TV...And the optical zoom is done real time - for a varifocal it is a set it and forget it. You cannot go to recorded video and optically zoom in later, at that point it is digital zoom, and the sensors on these cameras are so small which is why digital zoom doesn't work very well after the fact.
I'd recommend you consider a
Blue Iris/computer combo as an NVR. Keep in mind an NVR is simply a stripped down computer after all... And this would allow you the flexibility to mix camera brands.
You don't need to buy components and build one, or buy a new computer either.
When I was looking at replacing an existing NVR, once I realized that not all NVRs are created equal (the bandwidth is can process is a huge limiting factor), and once I priced out a good one, it was cheaper to buy a refurbished computer than an NVR.
Many of us buy refurbished computers that are business class computers that have come off lease. The one I bought I kid you not I could not tell that it was a refurbished unit - not a speck of dust or dents or scratches on it. It appeared to me like everything was replaced and I would assume just the motherboard with the intel processor is what was from the original unit. I went with the lowest end processor on the
WIKI list as it was the cheapest and it runs my system fine. Could probably get going for $200 or so. A real NVR will cost more than that.
A member here a couple months ago found a refurbished 4th generation for less than $150USD that came with Win10 PRO, 16GB RAM, and a 1TB drive. You won't find a capable NVR cheaper than that...
Blue Iris has a demo, so try it out on an existing computer and see if you like it.
There is a big
Blue Iris or NVR debate here LOL. Some people love
Blue Iris and think NVRs are clunky and hard to use and others think
Blue Iris is clunky and hard to use. I have done both and prefer
Blue Iris. As with everything YMMV...
And you can disable Windows updates and set up the computer to automatically restart in a power failure, and then you have a more powerful NVR with a nice mobile viewing interface.
Blue Iris is great and works with probably more camera brands than most VMS programs, but there are brands that don't work well or not at all - Rings, Arlos, Nest, Some Zmodo cams use proprietary systems and cannot be used with
Blue Iris, and for a lot of people Reolink doesn't work well either. But we would recommend staying away from those brands even if you go the NVR route with one of those brands...
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...
