This.
Unless you monitor the network it is very likely that it is pinging a Chinese server.
Many years ago we bought a treadmill with LCD screen and Android running on it with a browser and other stuff. Connected it to WiFi and were happy.
A couple of years later I got a Ubiquiti edgerouter, configured it and decided to check its deep packet filtering. It started showing me an odd Chinese domain being pinged periodically, like every 5 min. Don't remember the domain but it was some Chinese search engine/portal I had never heard of (not Baidu). It took me a while to figure out that it was the treadmill that was doing this. At which point I had to just disconnect it. I have no idea why it was doing what it was doing and what data it was sending and if I was running a backdoor in my home all this time.
Point I'm trying to make is, don't assume. Mistrust and Verify should be the modern day mantra for Internet connected, especially Chinese, devices.
- rbut 7y agoNot true, though admittedly I had the same fear. I have a Hikvision NVR and 4k camera setup. I keep them on a separate subnet and have blocked all access to other subnets and the internet via a Mikrotik router. In the year or so I have had this setup there hasn't been a single packet from the NVR or cameras in an attempt to access the internet.
- yangikan 7y agoIs it possible to still get alerts, upload videos to the internet with this setup? Any pointers?
- ol-sparky 7y agoyes and no. its a little work but you could whitelist a domain the NVR can connect to or maybe an IP. Block anything else. for example: if you want the NVR to upload to Dropbox, you would whitelist the list of domains that are needed for Dropbox to work. if the NVR tries to connect to 'heartbeat.hikvsn.cn' it would fail.
- a254613e 7y agoI don't have the above mentioned cameras, but I do have cameras that are completely blocked from the internet. The way I do it is: When I leave my home my home assistant will enable the FTP upload on motion detection feature of the camera. If there's motion then the camera will upload the recording to a ftp server running locally (synology), this then gets synced to google drive. Home assistant can also do push notifications if there's movement detected.
