    Another B52IR Z12 failing

    As the title says, another B52IR-Z12 is giving up the ghost. This is the 3rd one since last year. It's fine and then goes black and comes back on. The off time varies - from a few seconds up to a minute. The recording timeline verifies that the camera stops outputting a signal as the timeline...

    RF Detector?

    Is there a handheld device to detect RF and where it is emanating from? It would be helpful to show signal strength to pinpoint direction and closeness. Hell, it would be a bonus to show the activity/events of the RF in real time as well. Any suggestions?

    Weird NVR behavior

    Recently noticed random selections on the NVR viewing through HDMI on my LG monitor. Most of the time, the monitor is off. Sometimes when I turn it on to view the cameras, a single camera will be displayed, not the camera overview screen. It happens very randomly. It may not happen for a week...

    Lighting in a narrow side yard

    I've had a small dome PTZ on the rear corner of our soffit viewing the narrow side yard that leads to the gate to the back yard since 2020. I'd like to improve the lighting since it does not have IR. I tried using a cheap solar/battery light temporarily to experiment, but it splashes light...

    I know it's a pretty broad question to ask, but does anyone have any suggestions for an ANPR camera in a residential area. It would help to have some real-world experience to compare. I'm looking for something that can be set up as a stand-alone ANPR

    MS Edge Explorer option removed Windows 10 in latest update

    Well, with today's MS Edge update, it looks like Explorer was removed. The option no longer exists on my Windows 10 laptop. And while Palemoon does work, it is so painfully slow.

    Warranty period on EmpireTech cameras?

    One of my B52IR-Z12B LPR cameras is resetting. When it switches from Day to Night, it goes offline and comes back on a minute or two later in day mode, but switches back to night again and repeats the cycle. I purchased it in the first quarter of 2025, is it still under warranty?

    Low-cost label maker

    Hi all. I'm looking for a low-cost wire label maker to organize my network cable mess. I can't see spending hundreds of dollars on a DYMO as once it's used to organize my cables it will more than likely sit in a drawer or in a cabinet and forgotten. Any suggestions?

    One B54IR Z4E down during the storm

    The 5442 Z4E I put up recently went dark during the thunderstorm we are having. It sits right above the B54IR ZE which is working, and both are connected via combiner/splitter. I swapped the connections from the splitter at the NVR and the 2 channels status also swapped. I even replaced the...

    It's been a while since I mounted my PTZ cameras (just over 5 years) and I noticed a lot of rust on the bottom of the pole mount bracket. Is the PFA150 Pole Mount Bracket made from regular steel or is it aluminum like the camera housings?

    Same gallon of gas in 4 or 6 cylinder

    Someone explain to me how a 4-cylinder engine getting the same mileage as a 6-cylinder engine is more fuel efficient. They both burn the same amount of fuel in the same distance and a gallon of burned gas emits the same 20 lbs. of CO2 in either case. Other than reduced costs for the...

    Nosey neighbor?

    Yesterday, I swapped out the Lorex crap camera on our south side with a used Dahua 5231 2mp turret. I repositioned the FOV to the right as the bush my wife planted 3 years ago was now blocking the view. I also zoomed it all the way in to attempt to allow recognition of the person or vehicle as...
