Button Cell Bluetooth Transmitter

So much better than monitor Bluetooth button is no much easier to use

Purchased 2 weeks ago... no problems so far. Easy install (Base to wall with 2 mounting screws. Then attach two existing old doorbell button wires to the new camera head; then snap camera head onto the base.) ... Would like to have seen a better security feature where the camera head attaches to the base. I like that the power from the wires keeps the battery in the camera head charged, and also rings my existing indoor chime when the camera outdoor button is pressed, as well as alerts my cell phone. Also like the bottom facing camera to see the landing in front of the door for any package deliveries. (Very clear images). Unit has lights for improving night vision recordings that are activated by motion detection. They can be programed to turn on or off. Camera mode allows for All motion or Human motion. The All setting shows and records every vehicle passing by. The Human setting shows and records only people. The recordings last about 6 seconds or until no motion is detected. Each recorded clip is stored in the unit and can be viewed/deleted at anytime. Disliked recording every vehicle going by. The Doorbell unit alerted my cell phone when I was 30 miles away... wasn't sure it would do that, but it did. I haven't used the voice thing yet to talk to someone at the door, but seems to be a good feature. There are many more good features but probably one of the best is .... NO subscription cost.

This product is excellent. I can connect my cell with mixture through Bluetooth and doing live. Great product. Thank you.

I have 2 Sony RX100 M5 and 1 Sony RX10 M4. These cameras have Sony's High Frame Rate feature which allows to record approximately 7 second clips at 480 or 960 frames per second. The HFR feature allows you to trigger and record the next 7 seconds or the last 7 seconds. In this case I wanted to trigger all 3 cameras at once getting the last 7 seconds from 3 angles. I purchased 3 Revo VRS-Multi-W units and used all three receivers and only one of the triggers. You have to sync them together by turning on the transmitter and holding the record button. While continuing to hold the record button on the transmitter turn on each receiver. Then release the record button. At that point one transmitter will trigger three receivers. The Revo customer service representation advised me that I should not count on all three camera being trigger precisely at the same time e.g. all 3 videos starting on the exact same frame. For my purposes the difference are trivial if any, For standard frame rate movies I always sync them anyway in PowerDIrector using sync by audio...

I am new to off camera lighting, and this transmitter was like hitting an easy button!! Very effective and enabled me to get up and running quickly as I prepared for my biggest photography session yet. Love it!

I love this bluetooth transmitter! I lets me use ANY device with an earphone jack to play good music through my good sounding bluetooth speaker. It reconnects automatically too, so all I have to do is turn the devices on and listen. Kudos!

I'm using this to connect my rear projector and sound system wirelessly. I was using so far bluetooth based transmitter receiver which was providing low sound quality lagging and breaking. This one works simply out of the box, no setup needed, and quality is high. The only down side is that some simple audio connectors are missing, but I used those of my previous set.

Highly versatile and compact Bluetooth Receiver/Transmitter with built-in DAC. It has separate optical input and outputs and a dual-use coax line. The Bluetooth connectivity is solid but it might take a few tries with older Bluetooth equipment. Once you're connected, it stays connected. Highly recommended!

Paired easily to my bluetooth transmitter then paired to my other Philips speaker very easily. Good range and great sound

When teamed with a BlueSENSE Bluetooth audio transmitter, I've got great sound anywhere in my house. Easy to set up and great sound with my Yamaha receiver and CD player!
