What image sensor does the V3 camera use?

I was really impressed by the Cam v3 low light sensitivity. I was just curious to know what image sensor it uses. Does anyone know?

I asked ChatGPT and this is the answer I got: The Wyze Cam V3 features a 1/2.7-inch CMOS image sensor.

Iā€™ll tell you more than anyone has ever asked for about this in the forum so we have it here for future reference:

To be specific, all 5 variations of the Wyze Can V3 are using a:

  • Galaxycore GC2053 CMOS image sensor.

There are variations with 3 different SOCs:

  • T31AL
  • T31X (slight optimizations in firmware and features but almost identical to T31AL)
  • T31ZX (double the memory as the other 2 giving way better performance & video processing, also supports higher resolution, and more power efficient, advanced features like deep learning capabilities)

And 2 different Wi-Fi modules:

  • ATBM6031
  • RTL8189FTV (marginally better stability and performance)

But all 5 variations of the V3 use the same CMOS and have the same amount of RAM (16MB).

The only possible variation of the above that doesnā€™t exist is the T31AL SOC with the RTL8189FTV Wi-Fi Module.

Is it possible to differentiate the variants by Mac or retail packaging?

Is a t31xz with rtl possible? (Exisis?)

I know it is possible to tell the difference by MAC, but I do not know which is which. Some time ago we noticed that certain MACs (first 6 or 8 digits) had issues that other MACs with different 6 beginning digits didnā€™t, indicating the hardware differences batches coincide with MAC addresses, but nobody ever documented which is which.

The best way to figure it out which version you have is to follow the instructions for the Thingino project to detect which hardware is in your camera:

Just to add on top of @carverofchoice 's post:

It details the FCC ID of Wyze cameras and their respective SoC and WiFi radios. Based on Thinginoā€™s Github wiki, Iā€™m guessing T31A and T31AL is interchangeable for the WYZEC3F variant.

Iā€™m actually surprised at how many variation there are for each identical FCC ID. I would have expected they needed to issue Class II Permissive Change Letter for changing the SoC / WiFi radios. I know for routers you have to, but Iā€™m guessing itā€™s different regulation for cameras ? Then again maybe Z and ZX are interchangeable and the WYZEC3A variant is under confidentiality.

Nice! Thatā€™s a great reference! I knew about the Atom project, But since I never intended to install it, I didnā€™t really look through it much. This is excellent.

Just a heads up, the v3 according to my setup has 91 megs of ram? though that maybe 128 after image processing as the little MIPS cpu in the v3 probably has some integrated memory sharing graphics system for dealing with imagesā€¦ :slight_smile: .

Thatā€™s weird. Should be 16 MB of RAM. How did you find something saying 91 MB?
Maybe they are doing some virtual memory? IDK.

Whoops. Silly me. Just realised what I have is the Cam v4. What I should have asked was: What image sensor does the v4 use?

Information obtained from the public FCC records:

The SOC is an Ingenic T41

I think this is the V4 CMOS Sensor:
ā€œHL_2229_SENSOR_V2.1ā€


But I have no other information about it other than the above public information. Because of that, itā€™s quite possible that it is a specialized or proprietary sensor specific to Wyze. Theyā€™ve been doing a lot more of that kind of thing lately (good for them).

Very good details.

I would have replied, ā€œStarlight sensorā€. I can see why you are a maven.

Haha, thanks buddy.

Just curious, why do you want to know anyway? This is something very few people care about or have any use for unless theyā€™re trying to figure out how to modify the firmware or something. That is something that is very difficult on newer Wyze camera models though because Wyze has been switching over to using Secure Boot, which makes things very difficult to modify in any way, making these details useless/pointless to most people. I am curious how it will benefit you? Just trying to compare it against some competition or something?

Sorry for slow response. I took a look in my camera using htop from the ssh session. I donā€™t think that would be accurate anyway as the ram wouldnt be enough for kernel 3.x let alone its binaries and scripts. It seems closer to 128 if Im honest with maybe 28 or so reserved for image processing or some other system thing.

Oh also I found this page, which seems to confirm my theory of 128 Megs of ram:

16 MB ROM would make sense to me, as that would hold the boot image and yes, it can compress into that spaceā€¦Just wanted to help out :slight_smile:

Note this is for cam pan but i think the hardware specs are identicalā€¦inside of that is just a v3ā€¦
