Makevember Care Package

Posted by ralphjy Top Member Nov 21, 2019
Just received a surprise care package from E14, I think in response to my Makevember posts. Thanks tariq.ahmad  for the great bit of kit !!   A couple of interesting items that I'll need to figure out how to use in a future project:  a slim E14 2600mAh 5V power pack and the Molex antenna sample kit.     There were some other goodies - my wife has been coveting my E14 Blue Man, so she decided that this new one was hers......   One idea I have for the WiFi and ...

NVR Died

Posted by ralphjy Top Member Nov 2, 2019
The NVR that I use to store my ip surveillance camera video just died.  it has been running continuously for 14 months.  My experience with electronic equipment that runs 24/7 is that things tend to die in the 3-5 year timeframe.  Usually it's the power supply, especially if it's a wall wart.  Or with NVRs, DVRs, or network storage, it is usually a disk drive.  The unit is an Amcrest NV4108-HS 8-channel HD NVR.   I noticed that the unit was not functioning when I t ...
