Review: 4k Camera is great! (updated) - (UPDATE) I have to give it up to Reolink's customer service. They reached out to me to resolve my issues and to provide a very reasonable resolution to the issue that I had. Long story short, I received an updated NVR and I was able to hook up the 4k camera. I compared it to my 5MP camera and it does stand out and I was impressed. I am able to read the license plate of vehicles as they drive through the culdesac and the picture quality is nice. Installation was easy because the current holes on the wall lined up with the new camera as well. FYI - the older model NVRs are not compatible. When I received the newer NVR, it was slightly different from the one that I had. (Previous) purchased several of reolink products within the last 2 years. I started with the $500 NVR kit and over time added several additional cameras as the camera quality increased. Overall, I was content although they had issues here and there. When the 4k camera rolled out, I was excited to get it so I can see how it compares to the 5MP ones that I have. If I liked it, I was hoping to replace them out with addiional 4k cameras. To my major disappointment, these D800 cameras did not work with my 8CH NVR RLN8-410 although they advertise it as such. When my 4k camera did not sync, I was advised the older RLN8-410 did not work! Although it claimed it worked with ONLY 8CH NVRs, this is not true. There's no upgrade you can do other then to buy a whole new NVR.
Review: Reolink Cameras Are Great! - Reolink cameras have been a great addition for me. I have installed Reolink cameras on multiple homes and businesses. The company stands behind of their products anytime I have had an issue (which is not often!). The quality is better than one would expect.

## Features

- Human/Vehicle Detection: This IP camera is equipped with on-device detection technology to identify human and vehicles from other objects. With its accurate detection, you can keep a sharper eye on the true threats and release your mind from the unnecessary alerts.
- 4K Ultra HD Videos: The home security camera jumps from 5MP to 4K Ultra HD. It is 1.6X clearer than 5MP and 4X clearer than 1080p. Details you see around home or store will be reproduced perfectly in live streaming and playback. Audio recording helps to record the ambient sound for more details.
- Easy PoE Installation: Thanks to the power over Ethernet (PoE) technology, this outdoor camera can transmit videos and get power simultaneously via only one network cable. Easy plug-and-play for a reliable connection.
- Multiple Recording Options: The PoE cam supports to record 24/7 continuously when movement is detected or during scheduled time. Videos can be saved in the micro SD card (up to 256GB, NOT included), Reolink NVR or FTP server.

You can watch live feed, be informed of the emergency, replay key moments - all can be done on Reolink App or Client anytime and anywhere.

## Questions & Answers

**Q: How is it at resolving license plates at night (via ir led's)?**
A: The answer is, it is not a matter of day or night, the issue is a matter of resolution; even though this camera is "Ultra HD", the wide field-of-view comes in to play, and makes it impossible to read plates beyond a certain distance. 

The good news is that there is a formula to calculate whether a camera can read a license plate at a given distance.  For that the magic number that you need to know is that you supposedly need at least 40 Pixels Per Foot (PPF) of resolution to read a plate.  To determine the PPF, you divide the horizontal camera resolution in pixels by the Field Of View (FOV) in feet at the distance from the camera where you want to read the plate. 

A description of how to calculate this for any camera follows, but for those who want to skip ahead to the answer, the answer is, for this particular ReoLink camera, you would only be able to read a license plate if the plate was less than 50 feet from the camera, and the vehicle was stopped or moving fairly slowly.  Also while the illumination is actually a separate issue, at less than 50 feet and under those conditions, the IR illuminators included with the camera would also probably be sufficient on an otherwise clear night.  However a vehicle moving too quickly, or in fog or rain etc., may be unreadable. 

For more in-depth information and suggested alternatives, read on: 

For this camera, even though it's Ultra HD and therefore 3840 pixels in horizontal resolution, the FOV is fairly wide at 87.5 degrees, and this 87.5 degrees is essentially a fixed number, because the camera "zoom" is purely a digital zoom (as opposed to an optical zoom); when you "zoom in" with digital zoom, the camera is essentially faking it by just replicating the same pixels; the optical or true FOV remains unchanged.

Given the fixed 87.5 degree horizontal FOV for this camera, you have to do some math to convert the horizontal FOV angle at the camera lens into the number of horizontal feet that are visible at some given distance away, but this can be done using a right triangle formula and then doubling one leg etc; there are some right-triangle calculators online.  However as an example, at 50 feet from the camera an 87.5 degree FOV would translate to 96 feet of horizontal view, at 75 feet from the camera an 87.5 degree FOV would translate to 144 feet of horizontal view.

Given these numbers, dividing the 3840 pixel horizontal camera resolution by 96 ft and 144 ft respectively yields ratios of 40 PPF at 50 feet and 26 PPF at 75 feet.   Which means, this ReoLink camera should, in theory, be able to read a license plate at a 50 feet or less from the lens.

Now this also really presumes the vehicle is standing still.  Some additional caveats are, this camera has a frame rate of 20 fps.  If a car is moving above a certain speed, you’re not going to be able to get a clear enough picture to grab a plate, it will be blurry. 

Also, in terms of seeing anything at night, that is an entirely different matter; the illuminators provided with these cameras can supposedly reach out to 100 feet, but if you find them to be insufficient, there are supplemental IR illuminators available.  However your camera needs to have enough resolution to read plates during the day as previously discussed, or no amount of IR illumination will help at night.  Also note the 850 nm IR LEDs can be seen as a red glow by anyone looking directly at the camera or illuminator. 

Lastly, if you need to read a plate at a distance greater than 50 feet, you may want to look at Ultra HD cameras that offer optical zoom, and thus a tighter FOV.  We are looking at one made by Lorex (LNB9272S), but these are expensive and may not work with the ReoLink NVR, ONVIF compliance notwithstanding.  For example, there may be no way to get the optical zoom to work if mixing a Lorex camera with ReoLink NVR.

Hope that helps, and sorry for all the math.
