Review on 📷 ZOSI 4PACK 1920TVL 1080P HD TVI Security Cameras: Ultra-Clear Night Vision Waterproof CCTV Cameras for Home and Business Surveillance (720P, 1080P, 5MP, 4K HD-TVI Analog DVR Systems) by Cesar Rios

Too bad tech writers can't explain them in plain language. What would otherwise be a good system is weakened by bad writing, a nightmarish check-in system, and a hotline that requires you to leave a number (don't call us, we'll call you). For example, the instructions for installing the system state that you must follow the procedures. The setup just has stupid instructions. It probably could have been saved with a UX process to find inconsistencies, but that didn't happen. How does a wireless security system work, but there are many options on the market. I would suggest looking for something less disappointing.
