Standalone Mode with RTSP over WiFi?

simond83

I'm testing an OAK-1-Lite on windows with the DepthAI. Got it working over UVC, it's a great bit of kit...nice job!

I need a device that can be used for CCTV, but protecting a persons PII, so i need to blur faces on the device. I also need to run it without a host, so need a standalone solution, ideally with WiFi. I see that the IOT range is now EOL, so that leaves just the PoE range to play with, but this doesn't have WiFi from what i can see.

Q: Are they any devices current or future that support WiFi, or are you engineering that out?
Q: Would the below goal be possible?

Goal:
1: Flash device so it runs in standalone mode
https://docs.luxonis.com/projects/api/en/latest/tutorials/standalone_mode/

2: Configure IP

3: Load gen2 Face Blur model onto device
https://github.com/luxonis/depthai-experiments/tree/master/gen2-blur-faces

4: Setup RTSP streaming, "burning in" the face blur to the video output feed.

Additional:
Can the OAK devices handle 2 concurrent streams? 1 clean and 1 dirty (face blur on)?

Over time, we'd add more local models, like face mask etc, but for now, privacy is the main concern to get up and running.

Thanks, Simon

Hi simond83 ,
All of that (and much, much more!) will be possible with the Series 3 of OAK cameras!
Currently, you would need to couple it with a small SBC, eg. RPi (eg. RPi Zero for lower cost/power consumtion), to stream video over WiFi. And you can already stream 2 concurrent streams🙂 Also feel free to check streaming options here. Thoughts?
Thanks, Erik

Thanks @erik! So, the early access modules on your store, they're all Series 2? When do you expect the Series 3 to be available? To confirm;

-Will the S3 units support WiFi?
-With S3 units, there's no need for a RPi (i need all in 1 weather sealed), correct? Everything can be manged with the onboard compute??
-Can I configure 1 unit, then batch update a load more with that saved config?
-Any future plans for VP9 or AV1 encoding?!

Hi simond83 ! Yes, currently only OAK-FFC-6P is series 3, but it's very early access (thus such high price).

Yes, some models will support WiFi (TBD which ones)
Yep, exactly🙂
So this is actually what we are now working on; online platform for device management (RobotHub), so you would be easily able to deploy 10, 100, or 1000+ devices easily🙂 Currently it's in pre-alpha stage, and we plan to release it in Q4 this year.
For Series 1/2/3 OAK cameras not possible, as encoding is implemented inside the chip, and it only supports MJPEG/H.264/H.265. So until we use a different chip (maybe Series 4?), we can't (easily) support any other encoding.

Thanks, Erik

Just checking in again Erik. Any movement with deciding which S3's will have wifi? Ideally after IP67 with PoE 🙂

Hi simond83 ,
Some devices from S3 will have WiFi, but not all of them (for cost reduction reasons). Quite a few custom solutions already use RVC3 with WiFi modem actually🙂
Thanks, Erik
