When purchasing a home security camera, there are several important features to consider. Look for cameras with motion detection technology and night vision capabilities; these features will enable you to capture footage in low-light and even dark environments. Additionally, consider selecting a camera that is equipped with two-way audio capabilities so you can listen in on conversations or scare off intruders. Finally, consider cameras that offer cloud storage options, as this will allow you to access your recordings remotely without requiring additional hardware.
