double click the empty URL box to select an example, or enter a direct link.
Resize video by dragging the bottom right corner, click "popup"
to open in a new window, "max" to fill the screen, or select a preset size.

Text Extends Off Screen (PSS)
PSS software is not DPI Aware - when using a higher DPI setting with PSS (eg. 120 DPI) the text may extend off the screen.
If so then you have 3 choices; set your DPI back to default (96 DPI), edit PSS files manually, or use the
PSS DPI Fix
This issue should not apply to Smart PSS.
Cannot Login/Connect (PSS / iOS / Android)
PSS 4.06.2 - 4.06.5 and some iOS/Android apps may not connect to regular user accounts, only admin accounts.
To fix this enable the following user privilege in the device: QUERY_SYSTEM_INFO or r_SysInfo.
Or login with an admin account, which will have that privilege enabled by default.
This issue was fixed in PSS 4.06.6.
Note: Some firmware (eg. 2.608.GVxx) will not login with PSS 4.06.2 even with that privilege,
and will login with PSS 4.06.8 but will not playback (fixed in PSS 4.06.9).
Offline Devices Hang (PSS 4.06.5+)
When adding an offline device to PSS 4.06.5+ your system may hang - this does not occur in previous versions.
If your system becomes unstable use CTL-ALT-DEL to close PSSProject.exe, and then edit device.xml manually.
2.608.GVxx Decoding (PSS)
NetSDK 3.37 and higher is required for firmware versions 2.608.GV00 - 2.608.GV01 to properly decode video - this may also affect other firmware versions.
PSS software uses NetSDK so this means you need to use PSS 4.04+.
Note: decoding from devices using this firmware requires more system resources than previous versions.
Some 2.608.GV00 firmware tested on different devices did however worked fine with SDK 3.35 and above,
so it varies from one device to the next.
24/32-ch Device Config (PSS)
If you want to configure a 32-channel device using PSS you need to use version 4.04.6+.
Anything less and you will not be able to edit the "DETECT" or "ALARM" sections.
And if you are using firmware version 2.606.0024.4 or 2.608+ then you need 4.04.6 or newer to edit the "ENCODE" section properly.
24-ch devices have too many PSS issues to list. PSS 4.06.6 and 4.06.12 will not load device config properly for the 32 channel DVR (HF-S).
4.06.10 loads the config fine. With Firmware 2.616 you will need PSS 4.06.10, while PSS 4.06.2 works okay for 2.608.
Device Config Issues (PSS/SmartPSS)
For 2.616 firmware you may need PSS 4.06.12 to load all device config details properly.
With one particular 2.616 firmware on a 2014 4-ch DVR, 4.06.10 would not load cam names in the encode section - however 4.06.6 and 4.06.12 does.
Newer 3.2 firmware may have even more issues with device config - eg. Hybrid DVR with firmware 3.2 will not load motion detect at all in PSS,
and will not save changes made to motion detect in SmartPSS. SmartPSS "copy" to other channels does not work well either.
Smart PSS Issues (SmartPSS)
Version 1.00.2-1.00.6, Device Config does not work for most DVRs with old or new firmware.
Some new DVRs even with the latest firmware will not even connect with version 1.00.7 (eg. 3108H DVR).
SmartPSS 1.10+ does not work with 2011 and earlier firmware.
SmartPSS has limited firmware support for playback and device config.
Convert DAV to AVI fails (Play/Convert)
DAV files from old DVRs may not work with the latest Players/Converters.
This would generally be a PlaySDK compatibility issue with your firmware version.
If the DVR is from 2007/8 (first generation Dahua DVRS) you may need to use the original Dahua converter.
Here is the 2008 converter
or the 2007 ePSS software
(use Search, Player).
Ofcourse, sometimes the DAV file may just be corrupt or from a vary rare custom firmware.
DAV converter 3.31 should work for most 2010-2014 firmware.
DAV to AVI Corrupt Audio (Play/Convert)
This usually means the PlaySDK is not compatible with the firmware. Please try an older/newer version to convert those files.
Eg. PlaySDK 3.33 may not decode audio from old firmware properly (eg. 2009-2011). 22.214.171.12430 (and earlier) and 126.96.36.19925 will decode the older audio properly.
Multiview Limits (PSS)
PSS 4.01 - 4.05.3 supports 121-way multiview, while PSS 4.06+ only supports 100-way multiview.
Default settings vary from 32-way to 64-way multiview - this can be changed in PSS_Config.ini.
Old DVRs (ePSS)
2007-2008 DVRs will need to use a specific version of ePSS.
You may have to test different versions until one works for your device.
Match the dates of the software and firmware versions (or when you purchased the DVR).
