What the differences mean

Resolution

The Reolink Altas PT Ultra shoots 4K. The Google Nest Cam (outdoor or indoor, battery) tops out at 1080p, with HDR to compensate in tricky light.

Pan-tilt tracking

The Reolink Altas PT Ultra pans 355 degrees and tilts 90 degrees with auto-tracking, covering far more ground than a fixed camera. The Google Nest Cam (outdoor or indoor, battery) has a fixed view.

Pre-recording

The Reolink Altas PT Ultra keeps a 10-second rolling buffer, so a triggered clip includes what happened just before motion started. The Google Nest Cam (outdoor or indoor, battery) has no such buffer.

Battery and warranty

The Reolink Altas PT Ultra is rated for a longer stretch between charges and is backed by a two-year warranty, against one year on the Google Nest Cam (outdoor or indoor, battery).

Ecosystem reach

The Google Nest Cam (outdoor or indoor, battery) ties directly into Google Home, Samsung SmartThings and Amazon Alexa. The Reolink Altas PT Ultra works with Google Home directly, but needs a Reolink Home Hub for Alexa, Home Assistant or RTSP.

Which one to buy if

What owners say

Owners of both cameras value not paying a monthly fee for the basics, but come away with different favorites. Reolink Altas PT Ultra owners praise the 4K image and ColorX night vision as exceptional, and single out the 10-second pre-recording for catching an event that a typical battery camera would start recording too late for, while a recurring complaint is that the bundled solar panel cannot keep up with true 24/7 recording and the battery can stop holding charge in a hard freeze. Google Nest Cam (outdoor or indoor, battery) owners praise the free three-hour event history and how reliably its on-device AI tells a person from an animal, though a minority report Wi-Fi drops or slower than expected charging.
