    AC to DC rectifier search

    Another option is to use a computer power supply. Depending on the model some can supply 12 VDC at 18 amps. Some more some less. i.e. 120 VAC in with 12 VDC out. Have been using an old Windows computer ATX PS to run all of my 15 watt white LED outdoor lighting that turns lights on/off for...

    Automated way for the 54IR Day and Night profile to change?

    Have been using a LUX sensor to trigger a Dahua API to change day/night modes on a BI system for all cams. While time around sunrise/sunset works, LUX takes into account cloudy vs sunny conditions and switches modes based on light levels vs a preset time. The mode change is only active during...

    Dahua Camera Times - How close from Cam to Cam?

    Using the BI overlay does work and is easy to implement. Using individual Dahua cam time is the more challenging to implement. The overall issue is that Dahua does not support millisecond accuracy for their commonly used cams.

    Getting rid of old tools

    If in the city, place them in a box on your corner and label free. Someone will pick them up. The other option is to place in a bag and go to a garage sale. Place them on a table and leave. Craig's list under free. Or place them in a cart at Home Depot, etc.......

    RF Detector?

    The FCC has little interest unless there a proven RF interference issue caused by a radio operator (think ham/amateur/CB) radio. There would have to be a consistent cause and effect and directly pointing to your neighbor. If others in the neighborhood are experiencing similar RF issues at the...

    RF Detector?

    N9010B EXA has a nice Signal Analyzer that goes from 10 Hz to 44 GHz. If higher frequencies are needed, then another analyzer will be needed. To buy you are looking at $35K plus. Suggest renting for a day to keep costs down.

    Camera suggestions for outdoor, no power, no sun, no internet?

    One issue with power pole lighting is that not all systems are powered on 100% of the time. Some use one photo cell to turn on/off a number of lights. Thus the power will only be available from sunset to sunrise. If each light has its own photo cell, then power is most likely available 100%...

    Will give your script a try. Ran both w32tm /query /configuration and w32tm /query /status on the BI windows computer. The results are in the text file. Take a look and let me know if there is anything unusual going on. The NTP server on the router updates the BI computer. The cams are...
