Neighborhood Entry
Where did you preorder? I might consider getting one for review and demo to my neighborhood association. Looks like two bullets under the eaves, supplemented by two of these LPRs might be just what we need for reasonable entrance coverage. Just captured some video (yesterday) from an older Lorex... -

Updated NVR firmware published - NVR_78_79_EXX_V3.4.80_160718.zip
I did not attempt to restore my unit. I purchased via Amazon and was able to return it and purchase a replacement. My unit was Chinese and had been reconfigured with some kind of an English Language Hack. From what I have read, this is why I bricked it by applying the wrong firmware version. I... -

This is a screen print of what I was getting with putty...Also I cannot ping the camera using last known Ip address nor default 192.168.1.108. would connecting to a PC and using wireshark still work? -

Special Request
I got a usb to serial interface and tried the serial method as per that guide you mentioned. The best I could get was a scrolling gibberish and a few mixed chinese characters. Tried putty and real term. I'm beginning to think i have a bad bootloader. -

Interesting - That is what I did and the url came up as USA/IPCamera/PTZ/Lite/DH SD22A204TN GNI - Dahua Wiki. That is where I got the firmware update. The firmware file I was directed to was DH_SD-Zi-Themis_Eng_N_Stream3_IVS_V2.400.0000.4.R.20150607 and after reboot - brick! -

Updated NVR firmware published - NVR_78_79_EXX_V3.4.80_160718.zip
I attempted to update the firmware on two devices - nvr and camera - each time I bricked the device. At this point I have decided not to try again until I have some hardware that I can practice on. Since you have a Chinese version, you need to be careful. That is about all I know as I am new... -

Thanks! Ideal capture would be face and license plate. The 4 camera solution makes sense. Did not consider that. We have a small entry building that we use for misc storage and aesthetics. Could mount 4 bullets at each corner. So that is definitely a consideration. -

Thanks Cor35! Would be great addition. Question - How do you determine whether your camera is a Chinese model? As you might know, considering the number of posts I have regarding my attempts to unbrick, I bricked my camera trying to update the firmware after assuming I had a English version. Is... -

My neighborhood association needs security cameras to cover our front entrance for incoming and outgoing traffic. We currently have 2 Analog Lorex PTZ cameras which are not functioning correctly. They keep suddenly pointing down and have proven unreliable. I am thinking two Dahua Starlight PTZs... -

Being able to recover a bricked camera using various proven methods appears an almost necessary skill if one is to save money by buying cameras and NVRs from sources other than big box stores and online security stores. Noobs like me are clueless unfortunately as to the nuances of working with... -

Dahua IPC unbricking / recovery over serial UART and TFTP
Question, regarding the "*" key in the terminal window, is this key applicable for all terminal software like putty. If not, what should I look for in the software documentation to find this key. What is this keystroke for? Thanks. -

Dahua IPC unbricking / recovery over serial UART and TFTP
I did try a direct connection to my laptop and keep getting the same scrolling gibberish. I just don't know enough as to what to expect in order to rule out anything. I did test the dongle by shorting the rx/tx pins and was able to type directly in the console. I just wish there was a way that I... -

Dahua DH-SD22A204TN-GNI
I purchased this camera at Amazon a few weeks ago and bricked it trying to update the firmware. I've been unable to recover via a serial method after much help from forum members. Beginning to think there might be something about the camera itself such that older methods of recovery no longer... -

Dahua IPC unbricking / recovery over serial UART and TFTP
I'm still unsuccessful. I've tried (looking left to right) RX TX GND VCC as well as (looking right to left) VCC GND TX RX. I was able to get a continuous scrolling of gibberish but nothing in english. This continues as long as there is power. I've tried making a GND connection from the Dongle to... -

Dahua IPC unbricking / recovery over serial UART and TFTP
I'm still struggling with this and trying to restore the camera using the serial interface method. have some time to try before I am out of time to return the camera. As to the 4 pin UART connector, there is no indication on the board what the pin out is. I've tried each one and I do get a blue... -

Dahua PZT firmare upgrade
Good point - I was thinking a firmware update might solve the issue with me trying to add a Dahua Dome PTZ to my Hik nvr. But I agree with you - I'm probably going to end up bricking another camera and there has been no mention of firmware being the problem I am having with this camera. Might... -

Dahua PZT firmare upgrade
Decided to send the camera back for an exchange or refund since I am still within the timeline to do so. I might just go with an Hikvision Dome PTZ and avoid this headache altogether via plug n play. A bit undecided as I really like the Dahua model. I did order a CP2101 serial interface to have... -

Dahua PZT firmare upgrade
In looking at the circuit board on my camera there is a 4 pin male UART. I just happen to have this UP02 serial to usb interface that fits. It is a serial device I used to update firmware on RC Helicopters. Anyway, there is a serial GUI that runs it so hopefully I can figure out how to adopt it... -

Dahua PZT firmare upgrade
Not sure if my camera had chinese region firmware. The model number is DH SD22A204TN GNI. It came in a Dahua box with all English. It is not doing a boot loop. There are no lights, it does not respond to the reset button, and I cannot ping it isng the last ip address which was the default one... -

This is a continuation of trying to add a dahua dome ptz camera to my Hikvision nvr. So far I have been unable to access the camera via the POE port so decided to try upgrading the firmware.

How Do I Use A Dahua Camera With A Hikvision NVR?
I setup my network setting for static using 192.168.254.254, 255.255.255.0, and Default gateway 192.168.254.1. I then connected my PC to a switch and the camera to one of the ports on the switch along with a power interface that I have. I was able to connect to the camera from my browser and... -
