Very efficient battery camerasI am pleasantly surprised at how efficient these battery cameras are. After six weeks of use, they're still on 100% battery, even though I've already recorded a few clips and accessed the live image more often. The base station only needs a little over 2 watts of power, which is optimal for my application in the holiday flat, and the cameras will easily last the 3-4 months. However, when I first added the battery cameras to the base station, I had to switch off my 5 GHz Wifi, even though I connected the base station via Lan cable, but I have already read about this from other battery cameras.
