I can only post 2 links. I modified my external links and posted the raw captures and the PCB picture in comments.
Frequency: 315MHz, 390MHz
Modulation: Amplitude Modulation (AM)
FCC ID: HBW7964 (link 1)
IC: 2666A-7964 (link 2)
Device Model: 953EV/EVC
Manufacture Date: 02/15
Other Information:
- 3 buttons
- Link below contains information for decoding Sec+ 1.0 and 2.0. (link 3)
- Only capturing for 315MHz because 390MHz seems to only be for legacy devices (link 4)
