Wired security cameras connect to continuous power, which supports features such as longer video clips or continuous recording, but installation may require routing cable and securing a permanent mounting location. Battery-powered security cameras offer more placement flexibility without a constant power connection, though technicians or homeowners need to plan for battery charging and may add a power cable when continuous operation is needed.

Compare 2K and 1080p security cameras based on the level of detail needed, with 2K providing more image information for viewing and cropping important areas. For low-light performance and field of view, look for HDR, night vision, vivid color after sunset, and a wide, tall view that captures more of the scene.

Google security cameras can connect to a mobile app for live viewing, event history, activity alerts, and two-way communication, depending on the camera. Compatible smart displays, streaming devices, tablets, and voice assistants can also show camera feeds or control features such as an integrated floodlight.

Outdoor Google security cameras should use a model designed to withstand wind, snow, and rain, with an adjustable mount or suitable exterior mounting location that provides the needed viewing angle. Wired cameras need a compatible power connection for continuous operation, while battery models offer cordless placement, and floodlight cameras require hardwired power to replace an existing exterior light fixture.
