We all know the risks with Chinese-manufactured electronics -- and that's why we keep our cams off of the internet.
If I may add,
Regarding cybersecurity -or lack thereof.
I am reluctant to share with you a personal experience with an executive that works for a rather large hi-tech American...
My first post for help here...
I'm a bit new to IP camera internals so please forgive my ignorance.
I have a Dericam S2-32G I bought about 5 years ago -for my mom's house.
I ended up owning it, and it has been a good PTZ camera. Then about 2 years ago it's pan/tilt quit working.
On power-up it...
Flintman, Just a guess...but it probably needs new filter capacitors -those big round metal cans standing on end you see inside.
The kind of conducted 'noise' I refer to is inaudible to the human ear.
What you are hearing is likely to be power line frequency (60 or 120Hz) hum. Easy for humans...
Hmm, my first post as a noob...
Clutch, it occurs to me that your microwave oven may be leaking a little bit of 'RF' radiation. Check/clean the surfaces around the door..?
I'm a retired RF savvy black arts tech. I've seen a lot of weird stuff in the radio world and I'm skeptical of wifi for this...
