    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.

    Dahua SD5A225XA reboot mark: abort

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

    This is from Finnish importer/distributor of Dahua.

    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...

    Dahua SD5A225XA reboot mark: abort

    Thanks Wittaj, every day learning something new. Dahuas manual does not tell this. I will try it when threre are struggles again..

    Dahua SD5A225XA reboot mark: abort

    Ah, there it is! Also "days ago" in this camera when I click enable. What are these "old files" actually? Videos and snapshots on the card?

    Dahua SD5A225XA reboot mark: abort

    I couldn't have imagined that there even is AWG27 cable sold, but that seems to be the case. Now there is Dahua PFL2106-4ET-96 and 60W orange port used to supply. Reboots are almost gone. Directly from switch to camera. I'm probably going there this week to see the cabling with my own eyes.

    Dahua SD5A225XA reboot mark: abort

    Yes, I have noticed that Dahua + sd-cards are not reliable combo. What does that "auto delete old files" actually mean? Is it wiping also the recordings or just some temp files inside camera that user even does not see? I see no schedule for auto delete, only enable or disable. Or does it go...

    Dahua SD5A225XA reboot mark: abort

    I know they work outside, I have installed two myself in outdoor enclosures and they have worked fine over 5 years. However, my client wants to do his installations by the book so if something fails nobody can say those power supplies are only for indoors.

    Dahua SD5A225XA reboot mark: abort

    I have suggested him to install AC24V power supply to eliminate the PoE-problem. Further using of AC24V is not an option because in this case it should be installed outside enclosure and here it could be -30c during winter, and those power supplies are specified only for indoor use/temperatures.

    Dahua SD5A225XA reboot mark: abort

    He has two switch models he has tested. First is Milesight MS-S0208-EL. With this switch there is frequent reboots, I should say clearly more frequent than with Dahua PFL2106-4ET-96. When he changed the switch to Dahua PFL2106-4ET-96 and plugged in port 4 (>60W), camera still has reboots, but...

    Dahua SD5A225XA reboot mark: abort

    My client has several of DH-SD5A225XA-HNR 25x AI PTZ domes and some of them seem to have occasional reboots. In the log there is reboot mark: abort. This can happen right after IVS has been triggered and tracking has been started, but also when there is no events triggered (nothing moving in...

    Dahua SD card recording problems and most reliable sd card?

    Wittaj, thanks for your thoughts. My client is using continuous recording and 1 or 2 IVS rule to trigger motion recording. Over 10 Dahua cameras and all suffer more or less of SD card recording. Encode settings vary, but surely they are at least 20-25fps in all cameras. He likes to have smooth...

    Dahua SD card recording problems and most reliable sd card?

    Have been using now WD Purple 256GB cards for >6months. At the beginning it looked good but now there is issues also with those cards. Gaps in timeline and sometimes recording just stops and card needs to be formatted. After format recording starts again. How a security device can be this...

    Dahua's DSS Express or Pro

    Ok, thanks, got to test it. I assume the server process will be then running all the time and reserves some system resources? Not so convenient if user just wants to open it couple of times of day like SmartPSS and just check the NVR. Hope the SmartPSS support stays in Dahua devices still.

    Dahua's DSS Express or Pro

    I got reply also from Dahua support. SmartPSS is now included in the Dahua toolbox, it is not yet buried. But seems that the interest is more to develop DSS. If I have - to say - a system of NVR4208 with 8 cameras and want to install Dss Express to view NVR remotely, do I need to install both...
