## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ コスパは良いけど多分耐水性能が足りてないかな
*by ゆ***う on May 27, 2024*

自力で設置、この手の作業はそれなりになれてはいるので簡単な作業でした。POE対応のハブとケーブルを用意して接続するだけです。この手の中華製品の欠点は防水性能だと私は思っており、雨水にさらされる場合大体浸水して内部回路が壊れて使えなくなることが多いです。分解してみると分かりますけど、Ｏリングなど無いですから。ＩＰ性能歌ってるけどまあ信じちゃダメですね。このため、物によっては接合部にビニールテープ等を巻くとかなり長持ちするようになります。ただ、この商品の場合可動部が多すぎてビニールテープなどの防水強化は出来ません。軒下などの水のかからない場所に設置するのであればかなりお勧めです。コスパは良いですね。後気になったのは画角が狭いですね。レンズ自体が魚眼では無い。まあ、魚眼にして画像処理で歪みを直すなどをやるにはコストがかかりすぎるのでしょう。総じて、良い商品だと思います。ただ、高額の商品とは違い欠点はしっかりある、その欠点を理解した上で使用することが前提です。数万、数十万のカメラと同性能を求めること自体が間違っています。ご自身のやりたいこと、望む性能と天秤に掛けてお選びください。

### ⭐⭐⭐⭐⭐ 実証済み、コスパもグー
*by F***A on August 1, 2025*

購入して1年以上経ちますが、バッチリ使えて、機能も優れています。お値段もグッド、アプリも使い勝手が良いです。

### ⭐⭐⭐⭐⭐ 口コミの通りで期待してた通りでした。

ｗｅｂカメラを初めて購入しましたが、期待していた通りで満足しています。
