Review on 🔒 Enhanced Security Body PIR Infrared Motion Sensor Detector Doorbell Wall System with Intelligent Greeting & Voice Reminder by Dee Parson

I initially chose this doorbell because it has a wired connector on the back that allows you to activate this doorbell in many ways, in addition to an infrared motion sensor. I just sealed my eyes with tape as my usage was different. My project was to remove the speaker from my landline and use this pulse signal to start this device. I wanted to be able to use any sound clip file I wanted (humorous show clips, music, whatever). So now my phone has its own ringtone! Unstoppable fun. Mine is powered by a 12V DC wall transformer next to the phone. Now the tricky problem when trying to upload new sound files. All the instructions are in Chinese, so this is useless: HERE ARE THE INSTRUCTIONS: First, this USB connector is inherently female, so you might think it's the male-to-male cable that goes between the PC and the device , sufficient, but that it is wrong! The device was never intended for such work. Stupidly bought an M-2-M cable. What you need is a very cheap small USB stick. Keep in mind that the device only has 4MB of memory, so today's flash drive will be much larger. You only spend money to buy a bigger drive. The flash drive is only for storing sound clip files and nothing else! So find the oldest, dirtiest drive you can have. You must empty the drive of everything before writing sound clips to it. I assume you can run clips at around 320bps, but mine is 256bps and that's fine. MP3 format NOW THE IMPORTANT PART: With your files on the flash drive (and it matters when the last change was made to keep things tidy), insert the disc into the port, then press and hold the VOLUME + button for almost 20 seconds. You'll know it worked when the clip fails. The output sound level is good and I keep the device hidden in a closet. VOLUME - doesn't seem to decrease the volume, so I can recreate lower amplitude clips to get around this if needed. Much luck! Have fun with custom audio clips! Christopher It doesn't seem to lower the volume, so if necessary, I can recreate lower amplitude clips to get around this. Much luck! Have fun with custom audio clips! Christopher It doesn't seem to reduce the volume, so I can recreate the clips at a lower amplitude if needed to get around this. Much luck! Have fun with custom audio clips! Christopher
