If you’ve ever compared 4K footage to “full HD” (i.e., 1080p) video, you’ll notice a significant difference. 4K video has multiple times the quantity of pixels as 1080p video, which means it has significantly more detail.
So, if you have a smart doorbell to assist secure your property from theft, doesn’t it make sense to have a smart doorbell that records in the greatest quality possible? This is correct, but there are a few viable 4K smart doorbell possibilities (including Feels and a DIY technique), albeit you are currently pretty limited. Fortunately, a few smart doorbells have recording quality superior to ‘full HD.’
Smart doorbells and the problem with ‘full HD’ recording quality
Smart doorbells are fantastic since they replace (or sit beside) your standard doorbell and, in addition to alerting you when someone approaches your front door, they record persons who stroll close. This might be handy for crime prevention as well as keeping a watch on your community in general.
While many aren’t full-fledged security systems (like hardwired CCTV cameras), they perform many of the same roles, which means that recording quality is critical. Currently, many smart doorbells provide ‘full HD’ recording quality, which is 19201080 pixels. While this may appear good – especially because HD stands for High Definition – it does not always enable you to see people’s faces at night or even car plate numbers when they pass by during the day.
This can be aggravating, especially if you need to get a license plate number or view someone’s face in connection with a crime. When you can’t decipher these facts, you’ll wonder what the point of your smart doorbell is.
They are typically useful, but ones that record in higher resolution than full HD are much better.
Why 4K smart doorbells would be awesome?
I said before that 4K captures four times the number of pixels as full HD.
It’s practical twice as broad and tall (therefore 2 x 2 = four times as many pixels), but what does this mean? Paul Hibbert evaluated a 4K smart camera, demonstrating its different quality over full HD.
If you’ve been to an electronics/TV store in the recent decade, you’ve seen 4K TV screens that compare the quality to full HD – and they show a huge difference between the two video standards.
A 4K shrewd doorbell would be fabulous in light of the fact that, rather than attempting to make out vehicle plate numbers and individuals’ countenances from a good ways, you would have the option to do it easily – an unmistakable benefit over full HD.
So, are there any 4K smart doorbells on the market? So, in the next two sections, I’ll go through this.
Feels: the World’s first 4K smart doorbell?!
None of the major smart doorbell manufacturers, including Ring, Nest, and Eufy, offer 4K smart doorbells. In reality, a search on Amazon for “4k smart doorbell” yields… no relevant results. Oh, no.
There are a few clarifications behind this (as I portray in the “Defects with 4K brilliant doorbells” segment underneath) yet fortunately, Feels – a relatively new player in the smart home field – has a well-funded IndieGoGo campaign that has already resulted in the production of hundreds of 4K smart doorbells.
Unfortunately, despite original targets for December 2020 delivery, the most recent reports (as of February 2020) indicated what had pushed things back for various reasons, including China production delays and the pandemic effect.
There have also been some complaints from backers that the program contains several issues. New Feels app upgrades are coming out all the time to fix these issues, but the Feels 4K doorbell is still in the works. Nonetheless, I’m hoping that it’ll be able to overcome its manufacturing challenges since I’d want to put it through its paces.
Can you ‘DIY’ it because no other ‘off the shelf’ doorbells offer 3840×2160 resolution?
A DIY 4K smart doorbell
Several online instructions teach you how to create a smart doorbell yourself – using a Raspberry Pi. These range in price from $40 to $150, depending on what you want to accomplish, in any case, many individuals go for a straightforward 1080p (full HD) camera focal point.
Nonetheless, in April 2020, the Raspberry Pi blog unveiled a new 4K camera for $50. This can record at 40-60 fps relying upon settings, which is fairly momentous – especially given that Ring devices often only accomplish 15 fps.
On Amazon, you can also find a little cheaper Pi-compatible camera named Arducam.
This records at a higher resolution than 4k (at 4192×3120 pixels), however, only at 12 frames per second.
So, if you’re up for a challenge, creating your Pi-powered smart doorbell may be a great idea – especially if you use Sony’s official Pi camera, which can arrive at an undeniable degree of FPS even at 4K goal.
Why FPS matters (both the good and bad)?
FPS stands for ‘first-person shooter,’ as most gamers are aware. In this context, it stands for ‘frames per second.’ A frame is a collection of numerous still pictures that make up a video.
As a result, if a movie has 30 still pictures (frames) every second, it is referred to as a 30 fps video.
This is significant because if a video were just two frames per second (for example), you’d only get two pictures per second – resulting in an extremely jumpy film that may miss vital details like the license plate number of a passing automobile. As a result, a greater frame rate is preferable.
I am generally speaking! As the next section explains, a high FPS mixed with 4K video quality might be a drawback.
The flaws with 4K smart doorbells
The concept of high FPS, high-resolution video is fantastic: you can see people’s faces and license plate numbers even if they’re sprinting (or driving) by.
However, keep in mind that smart cameras include smart functions, such as only getting motion alerts if it detects a person. Alternatively, you can get notifications if motion is detected in a certain camera zone (such as a path or walkway).
All of this requires on-device computing power to function properly. However, the more frames in a video (i.e., the higher the FPS), the more needed processing power. This is also true for pixels: the more pixels there are, the more necessary processing.
On the off chance that you had a full HD 15 fps video (say, from Ring) and compared it to a 4K 30 fps video (say, from a DIY smart doorbell), you’d need 8x the processing power to monitor the video stream effectively and send out the required messages.
Ouch. This isn’t ideal, especially because it will inevitably cost more money because more powerful gear will be required.
Second, this needs additional storage space. In the event that you store the video cuts locally, your NAS should be multiple times the size of a full HD NAS to hold a 4K video.
If you keep the recorded video in the cloud, you will still need to pay for more storage space – and you may need to update your internet connection as well because the needed upload rates will be 4x faster!
The third fault with a 4K smart doorbell consumes significantly more electricity, whether plugged in or battery-powered. This is due to the additional processing needs of 4K footage than full HD video.
I record my YouTube videos in 4K, which drains my smartphone’s battery far faster than shooting in full HD; thus, what cannot overstate this point.
Finally, 4K smart doorbells are not widely available! Yes, the Feels doorbell is interesting, but it’s currently a very low-production device that won’t be widely available for a couple of years (if it does enter mainstream production at all, that is). So what’s the other option?
Suitable alternatives to 4K smart doorbells
If you want higher than full HD recording quality (which I do! ), there are two popular options: the Ring Doorbell Pro 2 and the Eufy 2K doorbell.
The Eufy 2K doorbell records in a resolution of – you guessed it – 2K. Uh oh, another buzzword! This is better than full HD but poorer than 4K, with a 2560 x 1920.
The Ring Doorbell Pro 2 has a resolution of 1,536p (1536 pixels tall). However, the width is unknown at the time of writing.
Finally, the Nest Hello records at a resolution of 1600 x 1200p. While this implies a narrower vision (1600p vs. 1920p for full HD), it also means a somewhat taller perspective (1200p vs. 1080p for full HD), which helps you see more people while they’re standing by your doorbell.
