Google Nest information based on Google's Nest support and store pages, Google's small business support page, NerdWallet's Nest Secure and Nest coverage, 9to5Google's April 2024 report, and SafeHome.org's 2026 testing of Nest cameras, as of October 2026.
Key Differences Between Our Security Cameras & Nest’s
A Security Camera Is Not a Security System
Since Google ended Nest Secure, a Nest setup is cameras and a doorbell, with no Google alarm sensors and no professional monitoring of its own. A camera records a break-in. A system detects it, alerts a monitoring center, and gets help moving. Citywide’s cameras sit inside a full system with door and window sensors, motion detection, glass break detection, and 24/7 professional monitoring. See how our home alarm systems work.


Recording That Doesn’t Live Only in the Cloud
Nest cameras upload footage to the cloud. When the internet drops, a camera’s internal memory holds up to an hour of events until the connection returns, according to Google. Citywide records on-site and in the cloud, so footage is not tied to the cloud alone. Hardwired PoE cameras feeding an NVR can record continuously on the property, with weeks of footage available.

Equipment Backed by a Local Company
When Google ended support for Nest Secure and Dropcam in April 2024, devices that had been working stopped functioning. Manufacturers do retire products. Citywide installs and services the equipment it puts in, from offices in Clayton and St. Charles, and has done so since 2010. As one customer, Rachel B., put it, “Cody the technician made sure everything was set up perfectly before he left.”


Smart Home Controls Built Into the Security System
Google Home is Nest’s strength, and it works well for people who already use Google’s smart home devices. The difference is what sits behind it. A Citywide system ties the alarm, cameras, smart locks, lights, thermostat, and garage together, so remote arming and location-based automation work alongside your security. Smart locks can disarm the system in one step for guests, with time-limited codes for visitors. Explore our smart home options.
Switching from Google Nest
If you own Nest Secure, that hardware stopped working when Google ended support in April 2024, so a replacement alarm system is a full installation. If you own Nest cameras, they are built around the Google Home app, so ask any company what it can keep before you plan around the old equipment. Either way, a Citywide technician walks through your home, designs the cameras and alarm together, and installs a complete home security system. The same local team handles service afterward.
