    Grounding Best Practices?

    I've been an electronics tech for 40 years working first working on 2 way radios and tower repeaters, then FAA RADAR and automation. I mostly agree with what Teken said. There are some extremes that can be done for lightning protection that I was involved in with the FAA. We don't have...

    Giving up on PC + Blue Iris- should I try an NVR?

    I went a different way. I do not have any alerts stent to me, but the system does have that capability. I did start with a NVR from Andy, but later due to power issues during a storm while I was away had too much trouble with the NVR when I returned home. I purchased a used server computer...

    DHI-NVR5432-16P-4KS2 won't boot up after upgrade

    It's been a good UPS. I've replaced the batteries not long ago but was surprised it did not pas the available commercial power through. A change is in the future. I have some timer relays that will hold off power for your set time after power is applied to relay. I'll have to wait till I...

    DHI-NVR5432-16P-4KS2 won't boot up after upgrade

    I had another power failure, this time while I was home. I shut down the NVR. When the power came back I turned it on and the UPS it is on went up and down a couple times taking out the NVR firmware again. So what actually took out my NVR and cams was the UPS and not a lightening strike...

    DHI-NVR5432-16P-4KS2 won't boot up after upgrade

    I fixed my NVR boot problem using a crossover cable directly from pc to NVR. I used a USB to DB7 serial cable to interrupt the boot process using *. Be sure to set the Gateway on your network settings to the NVR's ip address. Set up your ftp server to use your pc's ip address and the firmware...

    New guy from bama, need some recommendations

    If you were closer to Roanoke, I'd give you a hand. I ordered from @EMPIRETECANDY a few weeks ago my cameras and NVR. Shipping was quick and the system look great on my testing so far. I agree with the recommendations above. The 2mp starlight cams can see color when I can't hardly see...

    Any email/smart phone experts?

    Another vote for K9. I use it to get mail from different domains too. Works very well.

    Cameras and security lights

    I would really like to know about your exterior light control. That would keep me from attracting all critters within 3 miles. Update: Your post had me digging around. Found this...

    DAHUA NVR5XXX-4KS2_MultiLang_V3.216.0000002.0.R.20181106

    Irmware. It does not have a function to keep the IR lights off for use with external IR lights only. Does the previous version allow for this? I can hook the cam into my router and login through a browser to access this setting. Don't think it will stick if I ever change a cam setting through...

    Assistance with removing condensation from Dahua HFW5231E-Z12

    I know this is late, but may help someone else reading this. I have dried out small electronic items by opening as much as reasonable, wrap in paper towels, and bury in a large bag of rice for a few days. Another note: It is very possible to wash electronic equipment. You don't want to leave...

    network gurus need help on picking out firewall/router

    It's been a few years since I done some reading on dd-wrt.com, but I will consider options there for my secruity network. I was trained for N+ and A+ certifications and ran a home server for filtering when I had young children at home, on windows and linux. Most servers now are run on linux...

    UPS PROTECTION

    Hi guys, new member first post. I'm a recently retired electronics tech. The commercial power where I worked in Kansas was by far dirtier than the power from our non-inverter generator. It often had several harmonics that would run our transmitter power out the top of the acceptable range if...
