What reliable companies are there for self-service camera equipment?

At present, there are also many self-service camera devices. I read about a dozen or twenty on the internet, and there were self-service cameras more than ten years ago. At that time, only two or three companies did this, and they may have caught up with the policy in the last two years. Many companies want to make this profit. In the selection of equipment, it is recommended to choose old brands, such as: general certificate, easy access, easy license, etc. It has been done for a long time and is still being done, which shows the quality and credibility.
