This camera totally wire free, it literally screws to the wall and then connects to your phone APP through your Wi-Fi. It is the solution for areas that cannot be wired easily and ideally also receive a decent amount of sunlight.
It does not have to be in direct sunlight but it would charge better with a bit of direct sunlight a day.
The units come with 2 heavy duty rechargeable batteries, This can be upgraded to 4 batteries for a cost of €15.00 effectively doubling the standby capacity.
Under ideal conditions the sunlight received would power the unit and charge the batteries enough during the day so that the batteries can take over at night time and on cloudy days.
If however the batteries do drop in power they can be easily topped up by plugging a small USB charging cable into the underside of the camera. (supplied), using a standard mobile phone charger. (not supplied)
Under average conditions the standard battery pack should last 2-3 months before maybe needing a boost. And with the battery upgrade they should last for 5-6 months.
These figures are based on the unit being woken up on average 10 times a day, this is when the movement sensor on the front of the camera is triggered and it starts recording.
