What smart video doorbell to choose if the internet is unstable?

If you've got unstable internet, the main thing is to pick a device that works fine without cloud services. I'd recommend looking at video doorbells with local video storage, meaning built-in memory or microSD card support. That way the recordings will be saved on the device itself, not just on the internet. Second important thing - check if your doorbell can work with local network storage (NAS). Models like Hikvision or Dahua often offer this feature, and it really saves you when the network is acting up.

Personally, I saw a friend install a battery-powered video doorbell with local storage - notifications came with a delay, but all the recordings were saved. Important point: check the motion sensor sensitivity, because if your internet isn't stable, you might not get a notification quickly, but at least you'll find what happened in the recording history. Also recommend checking if the device supports RTSP protocol - that lets you view the stream through a local app without the cloud.

One more tip: if possible, think about a Wi-Fi booster or switching to a wired connection (PoE), it's way more stable. And honestly, for unstable internet I wouldn't really skimp on the device itself - better to get a model from a well-known manufacturer with good local functionality support than to end up disappointed later.
