Cost & Experience Impact
Technology Changes More Than the Feature List
| Technology area | User experience | Engineering / commercial impact |
|---|---|---|
| Connection architecture | Setup, local or remote access, display or App workflow. | Radio, firmware, software, service, testing and support scope. |
| Camera and night viewing | Framing, movement, room coverage and low-light viewing. | Mechanical, optics, controls, power and validation. |
| VOX and alerts | When the product wakes, notifies or changes display behavior. | Firmware logic, thresholds, UI and claim evidence. |
| Multiple cameras / dual-mode | Broader household scenarios and more interfaces. | Compatibility, UI complexity, testing and product positioning. |
