I know what Power supply ships from our warehouse with the unit.Typically, it is sold as a kit, and multiple power supplies are included in the kit.
There are a number of different things which can contribute to the power supply on application not matching the one that should be with the kit. We would need specific confirmation of the power setup.
The WD Purple is fine, as long as the power if sufficient.
In regards to the email,here is the thread discussing Email Alerts no longer working. Once a determination is made as to whether or not email will be supported in the units moving forward, I will post that information as a banner on the forum.
The motion sensitivity was bugged previously, and is discussed in this thread.
Reboot of DVR always sets Motion Sensitivity to HIGH - ZMD-DX-SIN8
Given your issues, you may want to call our phone based support, and we can assist you more directly. If the reformat issue isn’t resolved, we can set up an RMA to have the DVR and power supply come back to be checked out. This should not be a recurring issue with any of our products, and we have only been able to recreate the issue in house by underpowering the systems.
We are available from Monday-Friday, 8am-7pm CST, and can be reached at 217-903-5037.
