CES 2019: Arlo Unveils HomeKit-Enabled Ultra 4K HDR Security Camera and All-in-One Home Security System

Is 4K really necessary for a security camera??

Yes yes yes and more yes. Think about it. I can’t tell you how many times I’ve seen security camera footage that is 1080p or less and was frustrated because the license plate of the car is too far away to be legible, or the face of that person is just a blur, etc. I’ve been waiting for 4K and can’t wait for 8K security cameras in another 5 years or so. Super high Resolutions will make the difference between a perpetrator caught or one that is able to continue a crime spree. I will go as far as to say higher resolutions like 4K and beyond in security cameras will save lives. So yes.

Is 4K really enough for a security camera??

Is it unuseable without the service plan? Because thanks, but no thanks. I don't want the camera service to rob me before the physical robber does it.

Also, I wonder why HDR is supposed to be a feature... So I can really appreciate the burglar when he's at my window with the sun setting behind him?

Facial features can be very hard to make out, when the guy is wearing a hoody and standard 10 meters from the camera, so yes.

Because the robber’s face will not be overexposed or underexposed. So, you will get a perfect picture that you can send to the police, which means that the chances of the police finding the robber will be exponentially improved.

It’s funny, yesterday I had a pissing match with a dude on 9to5mac over the newly announced Netatmo doorbell compatible with HomeKit. That device doesn’t offer any cloud storage for video; instead it can save video to either Dropbox or FTP server. So, the dude was all pissy about it and basically had your attitude in reverse. No way in hell unless there’s a paid-for cloud-storage option.

To me, the optimal solution would be to have the Dropbox, FTP, and paid-for cloud offering. There are plusses and minuses of each, but why not have all these options? Additionally, if the camera becomes HomeKit compatible, why doesn't Apple allow us to use our paid-for iCloud storage subscription (I pay for 2 TB of iCloud storage but use only about 500 GB) for storing video footage?

I like the idea of the 4K HDR camera with two-way audio that provides the 180-degree field of view because it can serve close-by images directly from outside the front door as well as the images from farther away at the road in front of the house. That’s where the 4K resolution comes in handy.

The Netatmo doorbell will be useful for the close-up images from outside the front door, as the 1080p resolution is not high enough to see the detail of car license plates or people’s facial features while they pass in front of the house along the road.

Yes yes yes and more yes. Think about it. I can’t tell you how many times I’ve seen security camera footage that is 1080p or less and was frustrated because the license plate of the car is too far away to be legible, or the face of that person is just a blur, etc. I’ve been waiting for 4K and can’t wait for 8K security cameras in another 5 years or so. Super high Resolutions will make the difference between a perpetrator caught or one that is able to continue a crime spree. I will go as far as to say higher resolutions like 4K and beyond in security cameras will save lives. So yes.

While I agree somewhat, resolution isn't the only thing that causes license plates and faces to be illegible in 1080p security cameras - it's the wide angle lenses too. Put more accurately, it's a combination of the sensor, optics, and encoding that can determine whether an image is legible or not. Of those 3, we can assume encoding is probably optimized for the use. The next easiest and cheapest thing to change is the lense. Unfortunately with these consumer-level security cameras, the lenses cannot be changed. They all come with super wide angle lenses which is good for some but not all situations. It is usually those situations where a narrower field of view would have been better

Do the math: Most of these wifi cameras have 130deg field of view. At 1920 pixels horizontally, it is .067deg/pixel of view. US license plates are 12in wide. Let's get out our handy-dandy trig and solve some triangles:
At 10ft away, 1 pixel will cover ~1/8in. A license plate will be ~96 pixels wide on the image.
At 20ft away, 1 pixel will cover ~1/4in. A license plate will be ~48 pixels wide on the image.
At 30ft away, 1 pixel will cover almost 1/2in. A license plate will be ~24 pixels wide on the image.
At ~70ft away, 1 pixel will cover 1in. A license plate will be ~12 pixels wide on the image.

Just looking at those numbers, I'm not surprised license plates are illegible and faces are too blurry. This is why everything always looks tiny and far away on a these security cameras - the field of view is so wide that as soon as you get even a little bit of distance from the camera an entire person fits into a teeny-tiny portion of the screen.

We can up the resolution, but that in my opinion is not very efficient. It increases bandwidth use, and increases cost (more expensive sensor, requires more powerful microprocessor for encoding, etc.).

Merely changing the lense would really improve those numbers though as well:
A 90deg field of view lense, at 1920 pixels horizontally, would yield 0.045deg/pixel.
[INDENT]At 30ft away, 1 pixel would cover ~1/4in - a big improvement to the above.
A 70deg field of view lense, at 1920 horizontal, would yield 0.036def/pixel.
At 30ft away, 1 pixel would cover .2" - an even better improvement to the above.[/INDENT]

It would be far easier to give users replaceable cameras. Hallways, driveways, cameras facing an entryway are examples of cameras that don't need to be wide angle. A 90deg field of view in the corner of a room is enough to cover that room - there really isn't anything better about seeing wider. The super wide views are really only good for covering wide outdoor areas like an entire front yard with one camera.

Some video baby monitors come with 3 lense options - a standard 90deg view, a 130deg wide angle view, and a zoomed 70deg angle view. Arlo should do the same.

Is 4K really necessary for a security camera??

Are yours the battery powered cameras?

Yes

If so, does the motion activation work quickly.

I wish I could tell you - I don't use any features other than manually turning it on to go see the weather conditions at a vacation house. Honestly, I use it as little as possible as the batteries only seem to last a few months in the cold winter.

I'd love to upgrade to a built in rechargeable, but again, am totally turned off by the pricing.

Mine have been sort of flaky overall - IR filter gets stuck all the time (has for years) and video in daylight is usually "pink"...

Also sometimes they just lose connection with the base station. They come back after a while, but I've never been able to figure out why they sometimes just won't connect. I've tested even when there and it's all local - not an Internet issue or anything. Weird. At least it "fixes itself" though.

My setup "works"...but I think they charge way too much for what one is getting.
