While wireless may not be optimum for all requirements, for lower risk applications it can still provide adequate performance without the hassle of running any wires at all. While the Eufy cameras have an incredible up to one year battery life, this is managed by only recording when there is any motion, and the recording capacity is limited to the hub's 16gb capacity at present.
You will also find with these types of kits that the camera lenses are the one size fits all ultra-wide type, as such are best suited to lower down close-range applications. Also wireless also has limits, so for larger properties, a wired solution is still best.
On the whole, these are impressive solutions with the easiest of setup procedures.
(If you are looking for a more professional solution or for linking up buildings you can use a wired IP system and wireless bridges or various wireless adapters to become semi-wireless with mains power.)
