Hi. Yes you’re right it’s on the board …. And the only way to reinstall is the send your unit back Dahua will not send you the operating software have you checked the cooling fan ? Some early dahua units would not startup if fan does not start … also check your power supply

I am starting this thread to capture a bunch of information in one spot to assist those with "bricked" cameras due failed firmware upgrades. I bought my first Dahua IP camera just a couple weeks ago. I was impressed & pretty happy with it, but upon reading about new capabilities in newer firmware, I decided to upgrade it. Then like many others on here, I lost access to the Web GUI and the camera was no longer functioning. I spent the last two weeks getting to know everything about these cameras and this thread will capture all this information. It will take me several weeks to document all the information so please be patient. There are a variety of problems that I will try my best to explain and share the possible solutions. I have gotten pretty comfortable with these cameras and have purposely bricked them to various degrees of severity just to validate the recovery process. Most people "brick" their cameras trying to upgrade the firmware. This is not a serious issue and it can be corrected very easily. The camera runs an upgrade service on port 3800. The configTool always shows a default port of 37777 but this is not an issue as it can do the upgrade on port 3800 anyway. Change your port to 3800 and use a firmware file lsted below and you are back in business. I will keep updating this post as I get more time to write all the details around recovery. I will also post links to over 40+ firmware files that and which cameras they will work with. It will take me a bit of time to capture all this information, so please be patient. BRICKED CAMERA? How can you tell? There are several types of "BRICKED" camera conditions and they have varying levels of severity and also varying levels of complexity for recovery. Most are simple and caused by bad firmware uploads. The worst will require a full rebuild of the partitions which load the kernel, software and all other data. 1. The first step in identifying the severity of your issue is to determine what still working on your camera. In order to do that, lets remove as many variables as possible to the troubleshooting process. If possible, connect the camera ethernet and PC ethernet on it's own switch and make sure that no vlan tagging is enabled on the switch. Next, you need to figure out if the IP address is still reacheable. Ping the last known ip address. The default address for most cameras is 192.168.1.108. If you don't know it you can use the arp/ping method to configure which adds as startic arp entry to a new ip address. (This feature is enabled on the camera by default) 2. Once you have a pingable IP, you need to know what services are still active on the camera. This can be done with a simple port scanner. I have added a link to below in tools. 3. Run the port scanner and record which ports are still open. In many cases port 23 and port 3800 will still be open. If this is your situation, it is a very simple fix. If no ports are open, you will need to do a full image load which is more complex. The typical ports that you would see are: 23 - Telnet access 80 - Web User interface 443 - SSL 554 - Real time streaming port 3800 - Upgrade Deamon 5000 - UPnP 37777 - TCP Video streaming 37778 - UDP Video Streaming 42323 - Real time remote runner Plus a whole bunch more of UDP ports and more TCP ports REPAIR WITH PORT 3800 Download a step by step guide (DAHUA IP Camera Recovery v1.0.pdf) with screen prints @ http://tinyurl.com/lbl3up7 1A. If port 3800 is open you can connect with the Dahua Config tool (link below in tools). I tdefault to port 37777 but change it to 3800 as this port where the upgrade daemon is listening. Port 37777 is a redirect but it won't work if your firmware has failed. Launch the config tool and click on login button. Type the IP address , username and password then port 3800. Open a know working firmware file and upload to the camera. 1B. If port 3800 is not open, go to the next step to enable port 3800. 2. If you have telnet access, you can login with putty. Link to putty below in tools. The default Web UI password is admin / admin. In older firmware the telnet account is root / vizxv In newer firmware the telnet account is admin / 7ujMko0+"web UI password" ---> 7ujmko0admin Once connected you can execute a ps command to see running processes. /usr/sbin/upgraded process is what listens on port 3800 for the firmware binary file. There is also another copy in /var/tmp/ A useful tip for watching the upgrade process is to kill the "upgraded" process that is running and re-launch it in the foreground to watch the upgrade. ~#>ps 625 root 0:00 [mtdblock3] 630 root 0:00 [mtdblock4] 635 root 0:00 [mtdblock5] 772 root 0:00 [ubi_bgt7d] 776 root 0:00 [ubifs_bgt7_0] 790 root 0:00 /sbin/telnetd 798 root 0:00 [OSA_796_1] 860 root 0:00 syshelper elper 60 861 root 0:00 /usr/sbin/upgraded 869 root 0:00 [dsplogd] 870 root 0:00 [encode_guard] 889 root 0:00 [flush-ubifs_6_0] 923 root 3:29 ./VideoDaemon AEWB AF TVOUT ~#> kill -9 861 ~#> /usr/sbin/upgraded [OSA-APP] OSA Build on Apr 19 2014 at 09:55:50.

Here you can see each partition being loaded wit the individual img files. I will write a quick how to on loading each one individually at a later time. If you chose a valid firmware file, you will be back in working order. If you still have problems, repeat with another firmware file till you have a valid file. The IPC-HFW4300S-V2 is not natively compatible with all other 4300S firmware. I am in the process of writing a how to that explains how to over come this issue. UNBRICK WITH UBOOT via SERIAL NOTE: This section is coming soon... I'm gathering all the images I need for various camera types OTHER USEFUL INFORMATION (to be sorted later) The firmware consists of several images that are loaded into various partitions in flash in a UBI file system. You can load each partition separately if needed. More on this later.... (I'll put a guide together on flashing and recovering partitions) Once you telnet into the camera, there are number of useful binaries in the user shell that can help correct and diagnose some of the problems people are experiencing. One of the helpful steps is to kill the /var/tmp/upgraded process and run it in the foreground so you can see what is going on and easily capture error messaged. The /var/tmp/upgraded process is what opens the port 3800 and allows you to connect to the camera with the config tool if your web services have failed. There is also another copy in usr/sbin/. Also, in there is a command to reset all the parameters back to factory defaults (username, password, ip address back to 192.168.1.108 etc.) This can be accomplished with /sbin/clearparam. Another issue that people run into is the constant reboot issue. This can be caused by a failed process. The main application which provides all the camera capabilities (web interface, streaming, etc.) is /usr/bin/sonia. This process is what makes most firmware different from version to version (sort of). There are also changes to the web partition which contains the web server pages that /usr/bin sonia hosts on port 80. The sonia process is invoked by a shell script in init.d and if the process is killed, the camera reboots after a few minutes. This has cause many people issues when trying to "unbrick" the camera since you only have a few minutes between reboots. To stop the reboots you can update the flash. There is a parameter called appauto that tells the camera to auto start /us/bin/sonia. If you want the camera to start and not invoke the shell script that launches sonia, you need to set appauto to 0. This will stop the camera from rebooting when sonia is not running. This cam be accomplished by running '/sbin/appauto 0'. To turn it back on, just run /sbin/appauto 1. This writes the boot parameter in flash that the kernel reads before starting the process. You can check the current status of the appauto bootparameter with 'cat /proc/dahua/bootpara' It will only show what the parameter was when you booted up, so if you changes it you need to reboot to see the change in /proc/dahua/bootpara. Realtime streaming URL - rtsp://192.168.1.108/cam/realmonitor?channel=1&subtype=0&proto=Onvif You can change the subtype to 1 for the secondary stream also you can add user:password@ in front of the IP address if you have the permissions set requiring it. You can use the HTTP API to configure some parameters that are not yet in the web UI. For instance, another member discovered he could enable NFS through the web UI in addition to the local SD card. This config is not possible through the web interface as you need to pick one or the other. These documents details the API of Dahua video products (links provided to some of the versions below). Programmers or users can access and configure Dahua video products through the API. Every setting of the camera is available through the API whereas only a small number are available through the WEB interface. The document with version 1.10 is available with firmware version 2.0 and above. This document with version 1.20, 1.21, 1.22, 1.23,1.24,1,25,1,26,1,27,1,28 is available with firmware 2.210 and above.This document with version 1. 29 ,1.30, 1.31, 1.32, 1.33, 1.34, 1.35, 1.36 is available with firmware 2.210 and above.This document with version 1.37 is available with firmware 2.212, 2.4 and above. I have also done a bit of testing around the tftp process that is invoked in u-boot that looks for upgrade_info_7db780a713a4.txt and failed.txt. I think with a little more work, I'll figure out if there is a recovery method using tftp without serial access. This would be necessary if you lose telnet access and need to rebuild the kernel partition that hosts telnetd.

I have just started the process of uploading firmware... There are much more to come as well as many more camera models. Also if you have any you want to share please PM me what you have and where I can link them to this thread. Thanks to Euly for sharing firmware files! ___________________________________ IMPORTANT NOTE FOR IPC-HFW4300S-V2 CAMERAS The new camera appears to have differences (a few that I already found) that makes some of the general firmware incompatible with them. I have found a workaround, but it is complex. I will try to summarize it in a separate thread in the following weeks. I will also repackage the newest firmware files in versions that will work for the V2 cameras. Stay tuned! In the meantime, you can use General_IPC-HX5(4)XXX_Eng_N_V2.210.0000.21.R.20140613.bin or the PAL equivalent to recover your camera. Well, that's all I have time to share for now, but I'll do my best to put together a comprehensive guide to the inner workings of these cameras and a guide to unbrick in any failed software situation. Thanks and take care. Rob

Hi all. I am looking for a 4k external camera with >90deg fov with an SD card slot, wifi interface, night vision and smart movement detection. Dont need/want ptz or zoom. would love PIR! The object is to reduce cabling to a simple locally provided 12V only and not have any centralized NVR. I have found such cameras for 1080p but not much higher res.

Hi We are searching IP camera for controlling door entrance in shop(incide shop mall). We need to setup entrance detection by crossing entrance line and it will be better if there will be good face detection and calculation people traffic. What model can you recommend.

Hi if all you have is the dvr and not the 16 cameras to go with it …… then your best not wasting time on it that unit is 14 years old and it’s a SDI only recorder

Hi if in the uk I would look at the viper (TVT) 8 way 5mp dvr BB I have many of these systems out and never any problems it is the only unit on the market that is fully controllable via phones pads and pcs semding footage is as simple as an email direct with 8 cameras you will get 29 days with 1tb the app used is SuperLive plus

I had the same problem with mine and I just kept persevering. I think I eventually managed to get in to 888888's account using 000000 I then set up my own account Menu Advanced Account Add user I then signed in and deleted the 888888 account You probably know the above when you've got in but I hope that helps.... Other passwords I tried (as I cant remember exactly which one eventually worked ), were 09876 012345 and as above Good luck..... I'm in but can't get the settings right to view remotely, PC and phone

Hi your going to find it’s not true 4K like a lot of cheap cameras like in earlier post 4K with SD card is pointless you will keep loosing incidents smart motion is another problem with sd cards …… it will overwrite in a few hours adding a Poe injector or switch would it not of been simpler and much better to of used a Poe nvr then you would not need to use the P2P reolink software which in its self is a bad thing

Hi active is standard for cctv

Also cheap cameras at a higher resolution perform awful at night. A good brand of camera will give a specification sheet. For 4k (8MP), you would want near 1/1.2" cmos or larger... not a tiny 1/3" or 1/2.5" cmos sensor. In Reolink's video you can see how the person 'ghosts' into the background at points. https://www.youtube.com/watch?v=Y6Oxhxk8lxM Ghosting happens with a cameras exposure is too long for the amount of movement. A typical reason for a CCTV camera to have a long exposure is because the imaging sensor cannot capture enough light to capture a decent image. You can help reduce motion blur by adding external IR flood lights, but that adds extra power consumption.

Hi the problem with 4K and SD card storage only is the amount of data …… a day or so storage is pointless especially if you go away for weekend or on holiday it is better to have at least 2weeks storage to look back on cctv is not just for crime it also helps in other ways like disputes with parcels being delivered was it delivered or stolen also helps if someone else in the street has damage done to there cars …… it’s always good to view recordings going back more than a day or so many of my customers like seeing the wildlife around there property…… cats playing with hedgehogs…. Foxes and a customer sent me a picture of a albino badger and they are very rear in the uk

Hi. Good to see your going to do some homework first as far as the install goes with equipment today it’s easy and you will probably like the experience I was in Boston in November servicing a system

Hi problem with doing passwords is they need to be same day ( your screen shot) plus if the screen goes off it also need to be done again ….as is states on screen in red next screen shot can you leave cameras on

Hi not on a 2014 camera

Hi, I recently bought two of these cameras: http://www.amazon.com/Hikvision-DS-2CD2132-I-Fixed-Focal-Camera/dp/B00EJXK0I6 . Here are the specs: Hikvision DS-2CD2132-I 3MP Dome Camera 3MP (2048 x 1536) high resolution Full HD1080p real-time video Up to 30m IR True day/night IP66• Vandal-proof It supports PoE. Here's a video showing it's installation using PoE: My Router does not support PoE, so I used these PoE Injectors to add PoE to the Ethernet cable: http://www.amazon.com/Ubiquiti-Poe-15-Output-Ethernet-Adapter/dp/B002R7JPGE I would think my units were broken/defunct, but getting two that don't work at the same time is very unlikely, I would think. The distance is <100 feet (about 50-70 feet), and I'm using Cat 6A, so I doubt it's distance related. It crosses some electrical lines, but never runs parallel to them closely. I used a network tester to verify that the cables are crimped correctly and that PoE was indeed being added to the line. Everything checks out. However, my problem is that these cameras do not turn on. They do not appear on my network. It's almost like the PoE Injector just destroys the connection, and adds PoE to the Ethernet cable leaving nothing left. I haven't dealt with PoE at all before this, so I may not be understanding how it works. What could my issue be? What should I check? Are my PoE Injectors incompatible with this setup? Any help is appreciated. Thanks, Tremor.

Welcome to the forum Speed Test

Hi I just got a Hikvision camera DS-2CD2387G2-LSU/SL and I have connected using a TP-Link injector and when I look at my ASUS router it shows the port the injector is connected to as 'connection can be improved in orange' if I connect the camera to a switch I don't get this message and the port shows in green Just wondering if the injector is faulty after having it for so many years Also I would like to know if is there any difference between the using the injector or using the switch? I found the answer myself, the PoE injector I have is not Gigabite capable, it's only 100 mb and My ASUS router LAN port is 1gb I probably need to get a Gigabite Poe Injector although no single IP camera will use more than the 100Mbps capability of this injector Correct me if I'm wrong Thank you

salve, buongiorno a tutti

Okay, so I was playing around with the settings as my cameras would not display across the entire screen in 5MP@15/20 fps. It's a 1080p TV and just yesterday, it was displaying fine. Anyway, I started experimenting with a few settings - went into the PTZ menu that you access from the camera's main screen (not the DVR's main menu) - and I changed it from AHD or TVI to CVBS. Now both my cameras (as I changed both their default CVI setting to CVBS to check the aspect ratio) - are stuck in CVBS/ultra low resolution mode or SD. I can no longer access the PTZ menu. When I click on the main interface - nothing happens. I also noticed in the DVR's main menu PTZ settings (under "camera") that the Control Mode option is now greyed out. I can't even access that. This is driving me absolutely nuts - my CCTV camera feed looks like it's more than 20 years old! I'm not even getting colour on one of the cams now. It's just stuck in CVBS mode. How do I restore it to TVI, AHD or CVI? I've literally tried experimenting with every single option in the menu. Please HELP!! I have the Dahua dh-xvr5104hs-x1 with a Dahua camera and Pogo camera, both 5MP@20fps capable and 1080p@30 fps capable.

I have an 8CH H.264 Standalone DVR ZMD_DT_SCN8 DVR with 8 ZModo BNC Cameras attached to it. I installed 6-8 years ago. It went belly up yesterday. I would like to buy a replacement DVR and use my existing cameras. It appears that ZModo no longer sells DVRs My question is if I can use any DVR that has BNC inputs. Here is what the ZMode manuals says about its inputs. Analogue video signal: The video input port is BNC connector plug. The demand of input signal is PAL/NTSC BNC (1.0VP-P, 75Ω). Since I am replacing I might go with a 16 CH and adds some additional cameras later but for now I just want to get back up and running. Not much in the way of others requirements LAN, HDMI, Android, etc. I really don't want to install 8 new cameras. These are the cameras. http://surveillance.zmodo.com/700tvl-ultra-hi-reso-outdoor-security-camera.html And here are the camera specs: * 1/4" Color CMOS Image Sensor * 700 TV Lines, Horizontal * 3.6mm Lens * Signal: NTSC * Night Vision Min. Light: 0 Lux (IR On) * IR Irradiation Distance: up to 80' * Operation Temperature: 14F~122F * Weatherproof: Yes * Power: 12V DC * Mount: Wall * Video Connector: BNC * Power Connector: RCA 12V DC I did a search in the forum but didn't find any relevant posts.

Every dvr has a VGA (dvi) port where you can directly (~10 meters) connect monitor. Also you can find vga (dvi) extender over cat5 to extend the range. or you can use your LAN to access dvr

You have purchased the wrong injectors...those are specific to ubiquiti...they are not true poe standard 802.3af compliant..they will not work with your cameras at all..return them asap.. If you want injectors get these injectors (select injector not splitter or kit) http://www.amazon.com/TP-LINK-TL-PoE150S-Gigabit-Injector-compliant/dp/B001PS9E5I/ref=sr_1_1?ie=UTF8&qid=1416977530&sr=8-1&keywords=poe+injector or you could just buy a poe switch, this one will power 4 cameras (the other 4 ports are not poe, just standard ports) http://www.amazon.com/TP-LINK-TL-SF1008P-100Mbps-8-Port-802-3af/dp/B003CFATT2/ref=sr_1_1?s=electronics&ie=UTF8&qid=1416977620&sr=1-1&keywords=poe+switch&pebp=1416977653577

Great list but your Avigilon VMS pricing is way off Per channel Core ~$100 Standard ~$200 Enterprise ~$350
