2nd this configuration. My firewall rules block all external camera traffic and Frigate (once configured) is superb at detecting people without false alerts. All recordings are stored locally. It is disturbing just how much traffic smart devices try to send to China and Amazon, even when not subscribed to cloud services.
Home Assistant makes everything ridiculously flexible and is configured to turn on camera sirens if someone is detected at night or while my alarm system is armed, and disable sirens and alerts when doors have been opened or the alarm has just been turned off. The open Wireguard ports appear closed to scanners so I’m also reasonably comfortable with network security.
Besides the miserable experience unchecked advertisements cause, it is simply not safe to allow those advertisements to load.
A few years ago (before SSDs were common) I noticed unusual hard disk activity when loading a popular link aggregation site. A bit of investigation turned up a Trojan on my system. After removing it and reloading that site, my PC was immediately reinfected. The site owner denied any responsibility and said it was the advertising company’s fault.
The way the Internet operates now means no one is responsible for the content their site provides or the damage they cause. Imagine if restaurant owners were able to deny responsibility for the atmosphere in their restaurants or food poisonings they caused? IMO it’s the same thing.
Advertisers and websites have created the “dark traffic” mentioned here by repeatedly poisoning the public and they deserve the massive loss of revenue their behavior has caused.
