Univivi 90 Degree Wide Angle IR Illuminator

Univivi Infrared Illuminator, 850nm 6 LEDs 90 Degree Wide Angle IR Illuminator for Night Vision,Waterproof LED Infrared Light for IP Camera,CCTV Security Camera

The Univivi U06R turned out not to be all that wide angle. Despite the name it is really only about 60 degrees wide. That is great for long range applications but closer to you will probably want something wider like this 90 degree one. Here are some sample shots from my raccoon trashed barn to make it real easy to see the diff. This section is about 30 by 30 feet. The pics are with an Amcrest IP3M-943B

This is with the Univivi U06R 

And this is the same shot with wide angle

Both floodlight s put out about the same lumens. It is just the angle that is diff. Hence the 60 degree is brighter. Just over a narrower area.

Rollback Harmony firmware if your Harmony stops responding to your home automation.

Seems Harmony Hub FW 4.15.206 has a bug in it that cause the the hub to no longer respond to API requests. The simplest way to fit this it to roll back the firmware. Here are the steps that work from a  reddit post.

  1. Launch MyHarmony app on PC.
  2. Press Alt+F9 to open the advanced tools menu
  3. Scroll the window to find your Harmony model.
  4. Select "Factory Reset" for the appropriate model. This does not do anything immediately.
  5. Steps 1-4 will be displayed for completing a Factory Reset. We are only doing Step 1. "Restore" here means "Rollback".
  6. Connect your Harmony hub to the PC via micro-USB.
  7. Within a few minutes, it will be detected by MyHarmony and display Remote Model, Firmware Version, and Hardware revision. The Restore button will be enabled.
  8. Click "Restore" and wait. (Now is the first time that it actually describes that it's a rollback!)
  9. When it completes, you should be on Firmware Version 4.15.193. Disconnect the hub from the PC and return it to its original location.

You might want to block WAN traffic to and from your Harmony hubs till an update it posted.


Next morning my main remote was not talking to the matching hub. Tried to sync it but it seems that required unblocking the hub from the internet.
