    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%...

    One is never too old to learn new tricks! What is now helpful is the use of AI. Look into either Copilot, Claude or others. Most have a free trial where technical questions can be asked and answered. Many use these same AI engines for writing computer code without the need to know the...

    Dahua Camera Times - How close from Cam to Cam?

    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...

    Dahua Camera Times - How close from Cam to Cam?

    Not concerned at this time with the overall time. But more concerned that the cams vary so much from one another. Did a test using a static set date/time. Reset all the cams. And in a few seconds some were off. It would be my guess that it is a cam issue and related to the internal clock...

    Will be glad to share has only been tested on BI. It runs on PowerShell ver 5.1 - 7.6 plus one needs to setup a flat datebase file with a listing of your cam IP addresses of interest. That is nothing more than a text file with one line for each IP address. Will get that file ready to go...

    Dahua Camera Times - How close from Cam to Cam?

    Right now it is running on the system clock. From a historical aspect there has been a lot of drift on certain cams even with running NetTime using Google time. The BI box has no internet. Is there a way to make that happen?

    Dahua Camera Times - How close from Cam to Cam?

    It is using a local Asus router on the LAN as the NTP source. Overall, it appears that the issue is not the time, but the drift within the cams.
