Decent Kit With Poor Audio Quality
This kit is an improvement over an earlier ZOSI system, with slightly better cameras. The two-way audio quality is poor, producing garbled, high-pitched noises resembling cheap walkie-talkies. The DVR and box are standard and unchanged, and there is hope this unit lasts longer than twelve months. Overall, it is an OK kit and you get what you pay for. Customer support made every effort to resolve the sound issue, though it remained unfixed. ZOSI kits are still worth considering as they continue to improve.
Pros
- + slightly better cameras than previous kit
- + helpful customer support
- + good value for the price
Cons
- − poor two-way audio quality
- − garbled, high-pitched noises
- − DVR and box unchanged
- − durability concerns

Strong 4K hardware, buggy app and NVR software
A high-quality 4K system with excellent day and night image quality, a wide field of view, and easy installation using mounting templates. The NVR software feels outdated and laggy, with confusing motion detection modes that must sync with recording schedules; cameras sometimes flashed and sirens sounded even with alarms disabled. The mobile app is buggy, slow, and playback often freezes, making it borderline unusable. After contacting support, updated software resolved the issues. A strong, affordable option for commercial or domestic property protection, pending software improvements.
Pros
- + excellent day and night image quality
- + wide field of view
- + easy installation with mounting templates
- + affordable for a 4K system
- + support provided updated software that resolved issues
Cons
- − buggy, slow mobile app with freezing playback
- − outdated, laggy NVR software
- − confusing motion detection modes
- − random camera flashing and sirens despite disabled alarms

Cons
- − does not work outdoors
- − keeps cutting out
- − stops working
