    Purple flickering bars! Dead Dahua Ultra?

    Shipping will be very expensive because this camera is very heavy. Is there any guarantee that they will be able to repair it and any idea of cost?

    Purple flickering bars! Dead Dahua Ultra?

    It was 2015 or 2016 roughly. I unplugged the camera as to not cause further damage. Ill plug it back in and get the exact date. Could a bad power supply cause this behavior? I don't have another to test but I might buy a POE injector if I can find one capable of this power (38w). Any...

    Purple flickering bars! Dead Dahua Ultra?

    Nevermind, it’s back again :( Did a factory reset and still the same. The only other thing I can think of is to reflash the firmware. I've never done that on a Dahua because I've never been sure which files to use. Anyone think it would be worth a shot and want to point me to the correct files?

    Turned off WDR and it seems better... what would have caused WDR to fail?

    Purple flickering bars! Dead Dahua Ultra?

    Just a couple days ago my Dahua DH-SD6ALA230FN-HNI started flashing with purple horizontal bars and crappy image. I rebooted it and it got better but not perfect. Now they are back in full force. Is there anything I can do to try to fix this or is it toast?

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    I think you’re thinking about the angles in terms of a compass and the camera uses polar coordinates. In mathematics, 0deg would be East and the angle increases CCW, north would therefore be 90deg, West=180deg, South=270deg, etc... Polar Coordinates Nevertheless, the camera doesn’t know where...

    Dahua Captures mailbox break-in

    The zoom typically zooms great. My zones have worked very well. I normally would have gotten a great close up. Somewhat of a fluke I think. Then to compound the matter there is a time limit before it will re-aquire a motion target. He came in somewhat on the wrong side of the roadI'm going...

    Dahua Captures mailbox break-in

    Yep. All rebuild and good to go. Terrible to say but all the neighbors are a bit jealous now. Brand new everything. As far as this video goes... I've tried After Effects and Premiere but Im a novice at best so it wasn't much help. I feel like there is enough there for software of some sort to...

    Neighbor kids getting caught turning off power

    Mine was replaced at least 5 years ago. No more manual meter reading is the real benefit. I will be relocating my side fence so that the meter and panel will now be in the backyard . For now it’s padlocked

    Neighborhood Watch.

    Distraught young adult with gun. His family called it in. Police completely surrounded the area and put the school on lockdown. The dumbass in the car parked completely blocking the driveway of the corner house. My neighbor started to take a pic of the plate. This happens frequently with the...

    Neighbor kids getting caught turning off power

    Can’t see him actually throw the switch. I need another camera! He was just being a nuisance. No real reason. He got at least two other houses as well. I did get him on cam doing the house next to the one that burned. Glock 17 w/ crimson trace green laser and truglo sights.

    Neighbors house blows up

    Completely agree.... and in the future the first thing I would grab is my gas valve wrench and a face shield....I’ve already made a mental note of it. It’s really the only thing I could have assisted in in that situation

    Door checker avoids both houses with Dahua cams and checks all others

    He actually rips off my neighbor a couple doors over who did not have cameras. Other neighbor who did caught it on cam. You can see how he looks away while passing the two houses with cams. If nothing else, good deterant.

    Neighbor kids getting caught turning off power

    They knew it was there but underestimated it. Turned off my power. At first I thought it was a power outage but then I could see my neighbors lights on. Fearing the worst (trying to disable alarm system, which is on battery backup), with family inside, came out glock in hand through a side door...

    Neighbors house blows up

    Fire dept said combustibles near the hot water heater was the cause. It was a hot humid day. Not sure if that contributed. Kinda scary because I’m sure most of us have stored a can of gas for the mower in the garage. Maybe not next to the water heater but with gas vapor, how close is too close...

    Neighbors house blows up

    Nope, actually it’s almost done being rebuilt. It’s been 10 months. They removed the garage (including the slab and driveway) and two bedrooms above the garage, all plumbing, electrical, and drywall from the entire house. Thanks to the firewall the flames didn’t move much beyond the garage...

    Neighbors house blows up

    I was in the backyard and heard the popping from the ammunition. Peaked over the fence and heard neighbor call for fire extinguishers and I saw small fire and lots of smoke. Buy the time I came running out with the extinguisher the flames were out of control and I felt stupid standing there with...

    Neighbors house blows up

    Yep, all auto until the very end when I started watching the firemen on the roof. Looked like one guy almost slipped off the roof.

    Neighbors house blows up

    WWII vet and his wife both got out safely. I think he’s bulletproof. There were live rounds of ammo going off like crazy. Guy in black shirt gets hit in head at 1:25. Little bit of blood but he was ok. Scariest part was that the elementary school was just getting out and kids were all over. The...

    IP cameras over coax?

    That I have. I guess I should have said coax CAMERAS are foreign. Will I be able to set the zoom of the varifocal via coax, without rs485, or will I need to connect that for the initial setup?

    IP cameras over coax?

    I ordered a XVR7208A recorder, 6TB Purple drive, and a HAC-HDW2231R-Z camera and wall mount. Also got a Monoprice 16 channel 12vdc power supply, some BNC compression terminals, and power pigtails. Anything else I overlooked? I'm accustomed to IP cameras. Coax is foreign to me. Thanks for...

    IP cameras over coax?

    Is there a decoder for these model numbers? HVCI vs XVR? AN vs A at the end for instance? What’s the main difference between 5204 and 7204, 15 vs 30 fps? I don’t see much difference on their site. What about 1U vs, smart, compact, mini? Just physical size? 1U - Dahua Technology

    IP cameras over coax?

    I was really disappointed when I popped the plates and saw coax. It was built in '06 so I suppose back then it could have gone either way. Thinking back, it wasnt too long ago, 7 or 8 years, I built my outdoor bar/kitchen and ran a coax cable (for a Directv box) and never bothered to run cat6...
