I have a Stick up security camera, hardwired for power, (NOT battery) This camera has worked fine for 10 months. The video and motion detection are still perfect. Its the audio, that has begin causing issues 2 to 3 weeks ago.
When I play back a video, it has a constant, consistant high pitched squeal sounding off. I can still hear other sounds, but, the high pitch squeal is dominant. Then about 2 days ago, the sound has changed to like what an old dial up modem sounded like in the early 1990’s.
It squeals then gargles, some low pitched, squeals back n fourth.
I tried to attach an example but it will not allow mp4
You can go to the below link and click either of the mp4 files to hear.
Or these go directly to the mp4
Does anyone know what this is ?
