My mentor for electronics and embedded systems is sooo good at teaching istg. I walked up to this man after his class and I asked him and he explained the basics in 15minutes and when I thanked him he said “thank YOU for your queries “ bro he almost made me tear up cuz Engineering professors/mentors have been real rough 🙌

[just-my-insufferable-existance]

Should I actually make meaningful posts? Like maybe a few series of computer science related topics?

I would have to contemplate format, but I would take suggestions for topics, try and compile learning resources, subtopics to learn and practice problems

I got these ultra-cute little ESP-32-C3 micros the other day, they have teeny tiny 0.42" OLED displays built in, fantastic for putting a little sensor data or debugging info on. This is written on the Rust for ESP32 ESP-HAL using the embedded_graphics library.

That's a USB-C cable it's plugged into, for scale. You sacrifice some IO on this model but my plan is to use this to talk to my little air-quality sensor and have it report back to a server somewhere. This board takes battery power but I don't think it has battery management, I'll need to see how that works. I have lipo chargers lying around.

These are also the first RISC-V processors I've programmed. Fortunately as the guy who was my boss for like three months one time told me, you mostly don't need to care what the underlying architecture is unless you're doing really heavily optimized code or writing compilers. The ESP-RS project also works for the older Xtensa chips, which is handy especially because some of those are dual-core.

Unfortunately I've had trouble getting ESP-IDF-HAL to work, which is what you need to talk to the wi-fi side of things, but that is probably just me being absentminded somewhere. I'll figure it out, without wi-fi the ESP32's are much less interesting. There is an experimental wifi library for this HAL but if you're going to be doing networking you probably want the stdlib on your side anyway.

With ONVIF cameras, video footage can be securely stored in the cloud, providing numerous benefits over traditional on-site storage solutions. Cloud storage offers scalable storage capacity, remote access, and reduced hardware costs, making it an attractive option for building managers.

Moreover, cloud-based storage allows for the easy retrieval and sharing of footage, which is especially important in case of incidents that require investigation or legal proceedings. With ONVIF cameras integrated into the cloud, security teams can store vast amounts of video data without the need for expensive on-premises servers or data centers. This not only reduces costs but also enhances the overall flexibility and accessibility of the surveillance system.

Future Trends in ONVIF Camera Technology

The future of ONVIF cameras in smart building surveillance is promising. As technology advances, ONVIF cameras are expected to become even more sophisticated, offering features like 4K video resolution, enhanced low-light performance, and improved artificial intelligence (AI) capabilities. AI-powered cameras will be able to detect and analyze patterns in real-time, such as identifying unusual behavior or predicting security threats before they occur.

Additionally, the integration of ONVIF cameras with other smart building systems, such as lighting and HVAC, will create even more advanced and efficient surveillance solutions. For example, cameras may be able to adjust the lighting in a building based on motion detection, improving both security and energy efficiency.

As the demand for smart buildings continues to grow, ONVIF cameras will play a crucial role in shaping the future of building security. With their ability to deliver high-quality video, seamless integration with other systems, and scalability, ONVIF cameras are poised to be a key technology in the development of intelligent, secure, and efficient buildings.
