I would highly recommend PoE (yes that means running a wire to your router or a switch). I bought a couple of wireless wifi cameras (various brands, none Amcrest) and they are so unreliable. Constant dropped frames and loses connection randomly, bad quality, and can clog your wifi network. I'd recommend trying one out before buying more. https://www.amazon.com/Amcrest-Security-Wireless-Nightvision-Separately/dp/B08VF8839T/ref=asc_df_B08VF8839T/
