roscas•2d ago
We need more projects like this. I have a tp-link "tapo" home "security" camera.

Setup is made online. Then try to use that without a permanent internet connection... it turns itself off.

It needs a permament connection to tp-link. Now you imagine why.

cnst•2h ago
Yup, requiring permanent internet connection is such BS.

I had one of these "no-brand" cameras that had an integrated MicroSD card, which would make you think that it'd work just fine even without the internet.

We had no power in Austin for several days, but I kept my camera on a portable battery, because, why not?

After the power and the internet were restored and I checked the app, turns out, nothing was recorded! Even though it was online the whole time.

Such a major disappointment.

Sanzig•2h ago
I have two Tapo units at home, they seem to be working fine without an internet connection.

I created a new subnet and an associated WiFi SSID for it, connected the Tapo cameras, and set them up to act as RTSP cams. I then firewalled the subnet off from anything other than my Frigate NVR server and gateway. They still work fine, they are streaming video to Frigate without complaint. Maybe because they have DNS from my gateway still? (I should probably block that off, it's a common data exfil vector).

Very annoying that internet connectivity is required for initial setup, I'll agree there. They could have just had a bare bones web interface.

systemswizard•2d ago

happyPersonR•3h ago
Is there a list of camera models that are known compatible? I took a quick glance, this looks really cool!
efrecon•2h ago
Link from the homepage: https://openipc.org/supported-hardware/featured
stragies•2h ago
This is a list of SOCs, not a list of devices containing these SOCs.

And for most cameras sold, you'll have a hard time figuring out pre-buy, what SOC it contains.

cnst•2h ago
I'm happy for anyone who can make a use out of it, and it's nice to see one of the only examples where non-US users are ahead of the US, but…

Do you have any Amazon ASIN for any of these products, available for sale in the US?

There's a whole bunch of random no-name IP cameras available on Amazon US, often costing as low as $15 USD, possibly because some of them are subsidised by their cloud offerings, but I've never seen any of these brands listed on OpenIPC. I'm sure some of the brands we see, are simply whitelabels, but, how do you figure these things out, without a disassembly to look at the boards?

cure•2h ago
There seem to be a few camera manufacturers listed under "Supporters" on the introduction page, namely Goodcam and RunCam.
cnst•2h ago
It'd be really nice if any of the $15 cams on Amazon were supported.
cnst•2h ago
I've looked into it a few years ago when I was shopping and setting up my security cams. Super cool!

But, unfortunately, I wasn't able to translate any supported devices into an Amazon ASIN in the US.

Normally, many services on the internet only work in America. With OSS security cams, it seems to be the exact opposite. Eastern Europe and China are way ahead here.

roacato•2h ago
Despite the name, openipc isn't fully open - the main recorder/encoder app (majestic) is closed source. Many openipc developers have moved to an alternative project named "thingino" which has a fully open source recorder/encoder/streamer.
stragies•2h ago
This project only seems to support Ingenic SOCs (as per https://github.com/themactep/thingino-firmware). A far cry from the list supported by openipcam.

Edit: But they have a list of product names, where they support installation of Thingino: https://github.com/themactep/thingino-firmware/blob/master/d...

cnst•2h ago
> https://github.com/themactep/thingino-firmware/blob/master/d...

Good list. Happy to see Imou and Wansview on the list, these "unknown" brands have been selling directly on Amazon US for a while now:

https://www.amazon.com/stores/Wansview/page/1E1F86AB-C01A-45...

https://www.amazon.com/stores/Imou/page/73EC8A3D-1E78-42C5-8...

wltechblog•2h ago
The ING in Thingino stands for Ingenic. The Ingenic chips are MIPS, all the other cams are ARM. Focusing on these chips allows us to produce a firmware that actually works (not my experience with openipc) and is already configured for a specific product so you don't have to spend hours figuring out specifics for your camera to enable the hardware features!
stragies•1h ago
Thank you for your work! Can you recommend a compatible LAN POE camera available on Amazon(.de?)
wltechblog•15m ago
POE hasn't really made it to the commodity level you'll find on Amazon. There are some Vanhua models available on Aliexpress.. we also have some users successfully using various POE to USB adapters. I don't use one myself so i can't personally vouch for one... note that not all cams have data available on their USB ports, if you have questions about a specific choice, come visit us on Discord!
asveikau•2h ago
I guess encoder app is separate from encoder proper, because I have to assume the bulk of the encoder is done in hardware. I mean, those things can do realtime h265 in 4k without a beefy CPU or getting hot.
wltechblog•1h ago
Most of the image/video related stuff is done in the hardware, as well as a bunch of other functionality that would be hard to do on a 1 watt cpu. Check out the block diagram of the T31 processor: https://en.ingenic.com.cn/products-detail/id-21.html

Our streamer (prudynt-t) communicates with those blocks to handle settings, overlays, etc and receives the pre-processed image/video/audio data, packages it up for rtsp//mjpeg/etc, and handles client connections, motion sending, day/night vision, etc.

This is the status quo for ip cameras regardless of vendor!

crazysim•2h ago
https://thingino.com/

I love how the front page doesn't scream SOCs/SOMs to you and is just straight up here's the compatible cameras with pictures (with some SOM info below).

cnst•2h ago
Yup. And these cameras supported by thingino are also available on Amazon for under $30, too, some as low as $20 or below!
cnst•2h ago
> https://thingino.com/

> https://github.com/themactep/thingino-firmware

Nice, it actually supports several popular Amazon US "no-name" brands, including Imou and Wansview! (Plus, several mainstream Eufy, TP-Link and Wyze cameras are supported by thingino as well.) Seems to be more user-friendly than OpenIPC, too.

wltechblog•2h ago
I'm generally the guy making "easy installers" for Thingino cams. The default way to install on a cam is to use a flash programmer, some devices you can use a uart adapter.. I try to find opportunities in the factory firmware that allow you to flash using just a SD card when possible, and publish walkthrough videos on my channel. Some other devices you can flash with a flash glitch trick at boot, which I have several devices documented for that method as well. I'm a huge proponent of privacy and security being available to everyone and not just the technically minded user, and being able to get a commodity priced camera to faithfully serve a non-technical user is my goal!

More info is at my installers repo https://github.com/wltechblog/thingino-installers or my YT channel (WLTechBlog)

cnst•1h ago
Thanks for doing that! And welcome to HN!

Do you know if Wansview Q5 can be installed easily or not? I think it's one of the only cams on the thingino list that's available in the US with super-fast Amazon FBA shipping for under $20 USD and with lots of stock.

wltechblog•1h ago
The Q5 is on our supported list. I have a user who YOLOd and tried the Cinnado D1 (t23) installer and claimed success. Cinnado and Wasnview (and galayou and a few others!) are owned by the same company so a lot of things are shared.
cnst•1h ago
> I have a user who YOLOd and tried the Cinnado D1 (t23) installer and claimed success.

Oh, wait, Cinnado D1 is only $14.99! https://www.amazon.com/dp/B0CBBT5RMP

That's cheaper than Wansview Q5! (Unless the Woot deal returns.)

wltechblog•1h ago
yep I've got a video on the installation on my channel too!
skywal_l•1h ago
I wonder if there is business in buying those cameras in bulk, flash them with thingio and resell them as "open" camera. Not sure if it's even legal. I guess flashing the camera probably void the warranty and the margin would be razor thin anyway.
ww520•1h ago
It should be sold at a higher price. You perform a service by “unlocking” the camera.
wltechblog•1h ago
Our firmware is open source, if you think you can provide an upsell on pre-installed cams, go for it!
wltechblog•1h ago
There are people using Thingino to provide security camera services. Just selling the cam pre-flashed probably isn't a great plan as I go out of my way to make it as easy as possible for people to flash our firmware themselves!
cnst•1h ago
I have the impression that most security cameras on Amazon are subsidized with their subscription services.

Also, because many of these brands are no-name, you get the inverse volume discounts — you can get 1 camera for less per-unit cost compared to buying 2 or more.

Starting a business may make more sense if you're willing to go directly to the manufacturer, and have the manufacturer flash the firmware directly at the factory. Even then, why would people buy from you at $30 when they can buy an encumbered version for $15 and follow a few instructions?

cnst•2h ago
I looked at the list on https://thingino.com/ , and one of the cheapest cameras supported by thingino is Wansview Q5.

I'm NOT exactly sure on the exact version, because 2 different versions exist on Amazon, 3MP/2019 and 5MP/2024, in 2 colors each, but the older 3MP version is available for under $20.00 USD with FBA:

https://www.amazon.com/stores/Wansview/page/1E1F86AB-C01A-45...

https://www.amazon.com/dp/B07QKXM2D3 — $16.14 FBA for black 3MP Q5 Wansview

https://www.amazon.com/dp/B07QKWPT8J — $19.78 FBA for white 3MP Q5 Wansview

It's also been on sale at $9.99 on Woot a few months ago, but sold out.

https://electronics.woot.com/offers/wansview-2k-ip-security-...

EDIT: looks like the cheapest one in the US is actually Cinnado D1 2k, it's under $14.99 on Amazon.

https://github.com/wltechblog/thingino-installers/tree/main/...

https://www.amazon.com/dp/B0CBBT5RMP — ≤$14.99 FBA for Cinnado D1

thatcherc•1h ago
Cool! It looks like the Wansview Q5 has a similar SoC/camera/wireless setup as the Wansview W7, which as an installer guide on the Thingino wiki [1]. I wonder if that same installation process (but with the q5 firmware) would work. For $16 I'm inclined to try it out.

[1] - https://github.com/wltechblog/thingino-installers/tree/main/...

wltechblog•1h ago
Generally the cheapest fro Amazom is by Cinnado. I have a video on installing it my channel as well. I've bought this model for as low as $9.50 shipped. https://www.youtube.com/watch?v=phqR49t75Ak
cnst•1h ago
Wow, under $14.99 for Cinnado D1 2k is nice! Thanks!

It looks like right now it's available for 14.99 less the 25% promo code, that's $11.25 USD shipped, for OSS hardware? Niiice!

is thingino an alternative to open ipc? A newbie question

update seems like it's software for a camera module. Now I have to figure how to match that with cameras or how to connect it to my raspberry pi

wltechblog•1h ago
Thingino is a full replacement firmware for Ingenic-based ip cameras. While we have some overlap with OpenIPC it's fair to say that our missions are quite different. I don't consider us competing projects, they even use some of our code (and possibly vice-versa) in their firmware.
wltechblog•1h ago
The 5MP version is not yet supported! it's identical to the Cinnado D1 5MP, and in addition to the better sensor (and dual band wifi!) they use the next generation Ingenic processors. Work in progress!

Whenever I look into IP cameras I close the tabs because it feels like I walked into a store brand cereal aisle where all the boxes are exclaiming “Now with fewer razor blades!” or “Only half the reported cases of salmonella than similar store brands!”

What’s a good brand for IP cameras? What’s the best, in terms of open source support and reliability?

I need a mix of PoE indoor and outdoor cameras. 15 outdoor/10 indoor. Cost isn't a factor, I need something reliable.

dekhn•52m ago
I have used MindVision gigabit cameras, I believe they have some POE models (but they are mostly indoor-industrial-machine-vision. They do have a Linux SDK (basically a .so and a Python wrapper for the .so).

I'm going to look at all the links in the comments in this post to see if I can find things which are: better documented, more affordable, and easier to integrate.

fullstop•51m ago
While not open source, I have had good experiences with Reolink. They integrate well into Home Assistant and Frigate.
miiiiiike•44m ago
Yeah, I need open source firmware.
formerly_proven•32m ago
Yeah, you have to choose. Either a decent camera, or open source. Can't have both.
ejstronge•45m ago
There's no reason to re-invent the wheel - ipcamtalk has a comprehensive set of explanatory posts. Don't buy Reolink, avoid Amcrest - Loryta (rebranded Dahua) and Hikvision are the strongest, but there are other strong options, especially on the refurbished commercial camera front.
eco•19m ago
ipcamtalk feels completely captured by resellers and affiliates. I'd suggest taking any advice you see there with a grain of salt.
BehindTheMath•3m ago
What's wrong with Amcrest IP cameras?
infogulch•45m ago
Also very interested in PoE cameras with open source firmware. Most of these seem to be wifi + power cable; I figure if I'm running a cable anyway it might as well be a data cable. Maybe wifi is easier to set up a couple devices, but once you get to 5+ cameras PoE is worth.
formerly_proven•36m ago
> Cost isn't a factor, I need something reliable.

Don't consider at all: All non-OEM Chinese stuff (1 trillion brands, way too many to list, including the usual consumer garbage that you might find in a store like Reolink etc.)

Consider if cost turns out to be a factor: The two major Chinese OEMs, Hikvision and Dahua.

Note: All Chinese OEMs are obviously implicated in the Chinese surveillance state. Obviously. A lot of "major" brands are OEMed by these two, even ones you might not expect. For example, much of Panasonic stuff is rebadged Dahua. Basically 90% of any CCTV camera Made in China comes from either Dahua or Hik, the lesser brands just mostly get (or rather, choose) the bargain-bin hardware with monkey-model firmware and of course no FW updates ever.

If cost really isn't a factor: Bosch, Axis, Dallmeier, Mobotix

Note: Most of these you cannot buy directly, and the vendor won't talk to you.

> What’s the best, in terms of open source support and reliability?

These are found at completely opposite ends of the spectrum. All good CCTVs cameras use signed and more-or-less well encrypted firmware, even cross-flashing isn't much of a thing.

some_random•30m ago
Hikvision and Dahua make a lot of cameras but I wouldn't call them the major OEMs, that would probably Ingenic, Goke, HiSilicon, uhhh Sigmastar, probably others I can't recall. If you're looking for one outside the PRC, Novatek is based in Taiwan.
fullstop•18m ago
Doesn't Ingenic just make the SoC? For example, Wyze cams use an Ingenic T20, as do a lot of no-name cameras.
FuriouslyAdrift•11m ago
I've worked with Mobotix cameras before and they are fantastic... also about $3500.

Usually we go for Geovision (still around $300 - $800) or Axis (little higher).

some_random•35m ago
I really like Ubiquiti but they're pricey and to get the full value you really need to be running their network gear too.
pbasista•49m ago
This seems nice. But if I am looking correctly, it does not support the devices from the mainstream brands like Hikvision.

I am unaware of how good those typical $20 cameras are. Maybe they are decent. But for instance some of the Hikvision ones with 8MP sensors support 4K@25 fps.

I think that it would be great if there would be an open source firmware for higher-end cameras like those.

wltechblog•18m ago
Thingino doesn't support cams with ARM processors, we only support the chips made by Ingenic (which are a MIPS superset they call Xburst). We have a number of 4 megapixel (not 4k) devices we support, and are in the process of adding support for the next generation of Ingenic chips (Xburst2) which will bring up support for 8 megapixel (4k) devices.

We're also focused mostly on the less expensive models, because they're obviously within reach for a lot more folks but also they're almost always subsidized by the expectation that a discounted purchase price is made up for by the vendor's cloud subscription. You can get a LOT of great camera models for a low price.

I will say that there is a story about Hikvision that would likely steer most folks away from their brand.. it's bad enough that Google won't index it... With that said, I don't believe anyone should be trusting any third party with their video data in the first place...

infogulch•39m ago
Does this firmware work with open source camera recorders ("NVR") like Shinobi [1], Frigate [2], ZoneMinder [3], etc?

[1]: https://shinobi.video/ [2]: https://frigate.video/ [3]: https://zoneminder.com/

boredemployee•24m ago
tangentially, does anyone know of any open-source and reliable implementations of the "AI" algorithms used in those expensive cameras? I'm looking to use features like face recognition, people counting, and similar capabilities, but with my own hardware and regular cameras. someone said to "avoid at all costs yolo" so i'm looking for alternatives
