"A low hardware price that serves as an entry fee for a mandatory subscription."
The 'AI smart detection' spec means the camera can identify people and vehicles, but this intelligence is a service, not a feature of the hardware. After the one-month trial, that capability is lost without a paid plan.
This is for someone prioritizing a low initial hardware cost from a major brand and who is fully prepared to pay a monthly subscription fee in perpetuity. The wire-free design also appeals to renters or those who cannot run permanent power lines.
Anyone seeking to avoid monthly fees should look elsewhere; systems with local storage offer similar features without the recurring cost. Users who find the idea of frequently recharging and swapping four separate batteries tedious will be frustrated.
