    Dahua SD5A225XA reboot mark: abort

    And double check: I put back the previous MCU FW and did nothing else. In one hour got 3 abort reboots.

    Snow - blow me...

    Do you have a normal motion detection and IVS on the same time? I should put motion detection off and just rely on IVS. Normal (traditional) motion detection triggers on snowing and whatever.

    Dahua SD5A225XA reboot mark: abort

    News again. More than week ago I got a new MCU firmware from Dahua support. Probably it is customized as it is not (yet) available for public download. Since upgrading the MCU, camera has been working fine without reboots for a full week. I even put back the TAM1GT1GT-30 injector after upgrade...

    Dahua SD5A225XA reboot mark: abort

    Caught it finally. Almost 1 sec power spike of 40W. Although, connected to Hi-Poe port the switch should handle this?

    Dahua SD5A225XA reboot mark: abort

    It is AC 24V. Also states in the cameras carton box. Too pity it's wrong in the datasheet.

    Dahua SD5A225XA reboot mark: abort

    I must check the power supply tomorrow but I am almost sure it is AC. Would be tragicomic if that is also wrong in the datasheet. SD49225XA-HNR would be an option but I couldn't find it has autotracking as I looked in the specs. One option worth of testing could be also supplying 24V via...

    Dahua SD5A225XA reboot mark: abort

    Well, that is one option. Just trying to find the solution for my client. I personally would just put AC24V power supplies and be happy with that. But if they want to use PoE, it seems to be hard with these models..

    Dahua SD5A225XA reboot mark: abort

    I have news again. The dealer found out together with Dahua support that there is a moment when camera models current draw rises high and causes reboot especially when connected in TAM1GT1GT-30 injector. Dahua support recommended to use either Hi-Poe 75W injector or 24VAC power supply. It seems...

    Dahua SD5A225XA reboot mark: abort

    Yes, that's what I've been thinking also. It must be that these 25x and 45x HNR models have something which makes them reboot on PoE power. Sorry my English, I meant by similar = identical. So the dealer tested SD5A225XA and TAM1GT1GT-30 injector; just the same I have here.

    Dahua SD5A225XA reboot mark: abort

    Please read the whole chain and just my last message: "I just got report from the dealer that he has tested similar camera + injector combo and had similar results. " My client has several (near 10) of these cameras and all of them have reboot issues with PoE power. Some several times a day...

    Dahua SD5A225XA reboot mark: abort

    Actually the injector should be fine. I just got report from the dealer that he has tested similar camera + injector combo and had similar results. I also replaced the injector yesterday with Dahua PFS3005-4ET-60 switch but plugged the camera in port 2 (30W). This worked better than injector...

    Surge damage repeating

    I am not sure about that. Sheeps are not outside this time of year anymore, but it is possible it was in use when the last damage happened... have to ask.

    Surge damage repeating

    I was asking them the same about big motors or big power devices, but there is none in use anymore in the farm. Also no big radio tx nearby that I know. We'll see later what they found. It has to be something to do with power outages.

    Surge damage repeating

    That's the 24V access point PoE injector. LAN connector solder melted and foils blown out.

    Surge damage repeating

    Sorry, I might sound stupid, but if there is no lightning, where the energy comes from?

    Surge damage repeating

    That's what I thought also when I realized that camera chassis is attached to steel ceiling which is not grounded in the safety ground. To me it feels that there has been LOT of energy gone trough those fried devices. It needs >200C to get solder to melt. Could a voltage between two grounds do...

    Surge damage repeating

    There is no very long runs, just around 20m to the outdoor access point and <10m to the camera. Camera is attached to metal inside ceiling. With ohmmeter it seems that ceiling is not grounded to buildings safety groundwire. It is "grounded" via steel support bars. Now thinking, there might be...

    Thanks Teken, very interesting information. I will let electrician do the measurements and checks, let's see what he founds.

    Surge damage repeating

    That's exactly what I was thinking also. But the damage in these devices look so big that could it be ESD? I tried to find pictures of ESD damage in poe injectors / power supplies, but could not find any. In this time of year there is no thunderstorms in Finland.

    Surge damage repeating

    I'm not sure about the source, I was thinking the same that it might be separate as there has been big power consumers in the past. Nowadays just some lights and drinkwater-defroster. I have been thinking about UPS too, if the power is too harsh. However, I have advised them to get electrician...

    Surge damage repeating

    I have installed cameras on a site 4 years ago. There has been several devices damaged during these years. Poe switches, cameras, wifi access points and injectors. There are cameras in 3 buildings, and internet / lan connection to NVR is done with 2.4GHz wifi outdoor TP-link access points. In...

    Dahua periodic FTP upload messed! Does Dahua FTP upload have quota?

    I have had one Dahua IPC-HFW5541T-ASE doing periodic (2min) snapshot upload via FTP and internet to a Zyxel NSA362 NAS device with 2x6TB WD Red configured RAID1. I have monitored the progress just now and then looking that the folder structure is solid and I have also PHP script to pull out the...

    Dahua SD5A225XA reboot mark: abort

    And more news. Tested TL-SF1005P switch for one week. Works perfect, no reboots at all. Today I switched back the Dahua injector, and less than 3 hours I got the first reboot.

    Dahua SD5A225XA reboot mark: abort

    News again. Yesterday I replaced the Dahua injector with cheap TP-Link TL-SF1005P Poe+ switch. So far no reboots at all for 29 hours.

    Yes, I know, I have good communication with the distributor and we are trying to figure this out together.

    Dahua SD5A225XA reboot mark: abort

    Some update in my testing. Since 8th of september, I have replaced the cable with other 23AWG U/UTP cable. After the issue continued, I shortened the cable as short as possible. Now it is 4m between PoE injector and camera. As dealer advised, I also updated camera firmware (2.8.21 is the...

    Dahua SD5A225XA reboot mark: abort

    ljw2k, yes, my next test is to try other cables. I have quite good "test environment" so I can try different lengths and also factory-made cables easily. I will keep the forum informed about the progress...

    Dahua SD5A225XA reboot mark: abort

    ljw2k, that's what I thought also, but as my client has several of these cameras and those with longer ethernet cables have same symptoms, I think it must be a fault of camera model.

    Dahua SD5A225XA reboot mark: abort

    Update in the thread. I bought myself also one SD5A225XA to test if I can get the reboot mark: abort - problem repeated. Shortly: I can repeat the error message, and it seems to be related in PoE. Longer explanation: Zyxel POE12-HP injector, 20-25m AWG23 ethernet cable, Both RJ45 connectors...
