## 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.

### ⭐⭐⭐⭐⭐ Reolink Cameras Are Great!

### ⭐⭐⭐⭐⭐ Good picture and person/vehicle detection (motion not so much)
*by D***C on February 18, 2022*

The picture quality is good. Not great, it can't possibly be with the 8Mbps stream bandwidth at 8MP resolution. It can be used stand-alone or connected to a NVR; standalone can record on an SD card or store on a FTP server. The person/vehicle detection works great if you tweak the parameters a bit for minimum/maximum size plus duration. Motion detection is useless unless you place it indoors - too sensitive or too insensitive. There are severe compression artifacts with only 8Mbps bandwidth - to the point where you'd wonder if it's 8MP or just an upscaled 2MP sensor, but it's a security camera, not one for wining an Oscar. Night vision is good to about 60ft realistically. If there is a real floodlight to assist then the image is quite good. Even moonlight helps at greater distances. Push notifications are a bit annoying, going as often as 30sec and there is no picture or app deeplink to play from the event attached to the notification, all you can do is go to the live view. Emailed pictures for events on the other side are spot on (for person/vehicle). Some features are lost if you connect the camera to the monitoring ports of the Reolink NVR, but if you have it on the LAN side you can access them (such as pet detection) via the app. In all not bad given the price, features and image quality, plus it works seamlessly with the Reolink NVR.
