But be aware that they are rolling shutter and only barely synchronized.

Zed sucks, they eat into your GPU instead of on-board ASIC so you have no GPU left to do neural nets or anything else. RealSense on the other hand does computations on-board and consumes very little CPU and no GPU.

Zed cameras has a very hostile EULA (borderline illegal, but IANAL), I would not recommend using them unless it's absolutely the only option.

  Didn't know about that, could you point at specific bad parts?

You will not use Unauthorized Accessories. They may not work or may stop working permanently after a Software update. ii. You will not use or install any Unauthorized Software with an Authorized Accessory. If You do, Your ZED, ZED 2 or ZED Mini camera may stop working permanently at that time or after a later Software update. iii. You will not attempt to defeat or circumvent any Software technical limitation, security, or anti-piracy system. If You do, Your ZED, ZED 2 or ZED Mini camera may stop working permanently at that time or after a later Software update. iv. STEREOLABS may use technical measures, including Software updates, to limit use of the Software to the ZED, ZED 2 or ZED Mini camera, to prevent use of Unauthorized Accessories, and to protect the technical limitations, security and anti-piracy systems in the ZED, ZED 2 or ZED Mini camera. v. STEREOLABS may update the Software from time to time without further notice to You, for example, to update any technical limitation, security, or anti-piracy system. <...> ``` The problem with this license (beyond the fact that they are restricting a lot of user freedom) is that it's not specific. For instance, it's unclear if improving depth quality by applying an extra median filter is a violation of iii as it eliminates a technical limitation. While I don't expect them to actually go after their users, the fact that EULA is so hostile was the reason we can't use it in our team.

My company uses ZEDs now, and we are planning to use their new models which are weatherproof, and they currently seem to be the only inexpensive option for outdoor sensing that works out of box. And we don't like them: need your own GPU (at least they support Jetson & co.), not enough SW flexibility, USB-only connection limits the cable length. Longer-term, we plan to use our own software with either a pair of conventional machine vision cameras, or, preferably, find some ready-made assembly of a pair of cameras + SoC with full user programmability since we like to be in control of our perception algorithms.

  You can make extra-long USB connections with USB-over-fibre products like [1] (if you've got the money) [1] https://www.amazon.co.uk/FIBBR-Cable-Female-Active-Extension/dp/B07BVZGKZD https://www.amazon.co.uk/FIBBR-Cable-Female-Active-Extension...
