MV73X install

[Karl_Jacobsen]

Hi all,

       I'm installing my first MV73X camera and I'm a little confused as to the use of the 12V line. The 73X has the normal RJ45 line for power/data but it also has a 12V line that connects to a screw type connector marked 12VDC. Is the for additional heating of the unit in cold temps? The install guide doesn't seem to mention it.

You can use either one, you don't need to use both types.

This is because this camera supports Wifi, so you can use the power supply and connect via Wifi, without the need to use a network cable.

+1.

Also, if you have a legacy camera deployment using coax cables, you can  run the power along the coax and use a "MV Low Voltage Power Adapter (LVPA)" to power the camera.

So is the 12VDC line to power the camera like the PoE would? I'm having an issue with snow accumulating on the camera, especially overnight. I can address this by trying to add a shield around the mount but it's tricky....

[alemabrahao]

Exactly.

Got it.... we'll have to find a way to shield it. Thanks!

There are sprays you can put on the dome for water to run off, these might also help with snow.  I think @Ryan_Miles has used them and commented elsewhere.

I think he mentioned rainx.

Might have been this comment from another Merakian

Thanks @Ryan_Miles, indeed it was @GreenMan and RainX does state that it helps keep snow off as well 😎
