Firmware Update Dahua IPC-HFW1320S-W

For the test, I will update the firmware on the IP camera Dahua IPC-HFW1320S-W.

Let’s see what firmware is installed, open the web interface of the device, select the “Setting” tab, on the left the “Information” – “Version” menu.

In my case, the Russian version of the firmware was installed:

System Version 2.400.0001.11.R, Build Date: 2017-04-01
WEB Version 3.2.1.392220
ONVIF Version 2.42

Let’s see a new firmware on the official site and download it
https://www.dahuasecurity.com/products/productDetail/5631

The firmware file is usually in the archive, so unpack it.

In the web interface of the device, open the “Setting” tab, on the left in the “System” menu – “Upgrade”.
Press the “Browse…” button, select the file of the new firmware unpacked from the archive and press the “Upgrade” button to start the update process, which will last about 5 minutes, at this time you can not turn off the power of the device.

I was flashing with the English firmware, after the firmware in the “Information” – “Version” menu, the following was displayed:

System Version 2.400.0000000.16.R, Build Date: 2017-08-31
WEB Version 3.2.1.490211
ONVIF Version 16.12(V2.3.1.458331)

The solution of the error “Kernel failure” and “Out of memory” in Mikrotik

There was a problem, often began to reboot itself MikroTik CAS125-24G-1S-RM.
The firmware at that time was the last one – WebFig v6.9
The following information was displayed in the logs:

System rebooted because of kernel failure
Out of memory condition was detected
router was rebooted without proper shutdown

Having looked in “system” -> “resources” it was evident that the free memory of the device is constantly decreasing.
Then I began to recall what was involved and configured on the device.
Bumping into and looking “Cache Used” in “IP” -> “Web Proxy” it was evident that the size of the cache is constantly growing.
From here it was clear that when the device’s memory was running out and the kernel crashed.
Therefore, the solution to this problem was to restrict the proxy cache by specifying the maximum size in the “Max. Cache Size“.
Done.

Configuring Cloud in Mikrotik

Starting from the version of RouterOS v6.14, the Cloud function is added which allows using the Dynamic DNS name for a device that is automatically assigned and can be accessed by it even if the IP address is changed.

Example of switching through the console:

ip cloud set enabled=yes

Example of viewing parameters:

ip cloud print

Enable device time update with DDNS server time (if SNTP or NTP service is not configured):

ip cloud update-time yes/no

Immediate update of DDNS:

ip cloud force-update

View the DDNS name:

ip cloud dns-name

View the public IP address to which DDNS is bound:

ip cloud public-address

Binding DDNS to a local IP address instead of a public one, for example to 192.168.1.101, etc.)

ip cloud advanced use-local-address yes/no

View the current status of the Cloud (updated, updated, error, etc.):

ip cloud status

Through the graphical interface of the Cloud settings can be found in the menu “IP” – “Cloud”.

Reset password on HikVision cameras and DVRs

On the test, I reset the password on the DVR DS-7204HQHI-SH with the firmware version 3.1.3.
Since to him probably some schoolboy picked up a password, changed it and wrote mucks in the names of the cameras :)

The first step is to download the SADP utility from the official site
https://www.hikvision.com/en/Support/Downloads/Tools

Run the utility, connect the device to the same network as the computer or a direct cable to the computer.
The utility displays the connected device, as well as its serial number, in my case:

DS-7204HQHI-SH0420150505AAWR516895417WCVU

We copy this serial number, removing the model of the device in the beginning, in my case it turned out:

0420150505AAWR516895417WCVU

Open the security key generator, enter this serial number, specify the date that is set on the device and generate the code.

Open SADP again, select the connected device in the list, click on the “Forgot Password” on the right, enter the code, then enter the new password in the “Admin Password” line.
Now you can enter under the admin login and the specified password in the web interface of the device.
If the device was hacked, it is desirable to immediately reset the settings and update the firmware to the latest.

Code generators can be found on the Internet, for example, here are a couple of online generators:
http://hikkvisionpasswordreset.github.io
https://ipcamtalk.com/pages/hikvision-password-reset-tool

Also, the code can be requested from HikVision technical support or the store in which the device was purchased.
