A few days ago, I received two cameras from Amazon: the C225 and the C520WS. After a couple of days, I tested the two-way communication mode on the C225 and discovered that I couldn’t be heard (at maximum volume, I could only hear fragmented sounds, and even then, only by placing my ear almost directly against the speaker). In the alarm settings, when playing different sounds, they were also extremely quiet.

At the lowest volume setting, the sound is clear but very quiet. However, when set to maximum, it becomes only slightly louder but distorted (like over-amplification or something resembling a torn speaker).

I performed the same tests on the C520WS, and the volume was perfect on that device.

I also tried resetting the C225, but it didn’t help. Even during the first sound test after the reset, the output was still quiet and distorted.

Unfortunately, I didn’t think to test the speaker before updating the firmware, which the camera suggested automatically. Could you please advise if there’s a chance this is a firmware issue, or is it a physical defect, and I should request an exchange through Amazon?
