Slow download speed of recordings in SmartPSS Lite

Hi everyone!


Let me explain my setup.
I have a Dahua WizMind Series 5 IP camera installed in a sports complex. It’s connected via PoE to a Hikvision PoE switch, which in turn is connected to the ISP’s router.
Recordings are stored directly on the camera using a 512GB SanDisk Ultra microSD card.


From home, I access the camera through SmartPSS Lite, added by public IP on port 80, since port 37777 doesn’t allow the camera to be recognized.
Everything works fine — I can view the live feed, playback, and settings — but when I download recordings, the transfer speed averages around 1.5 Mbps (according to Windows Task Manager).


Is this normal? What could be limiting the download speed?


Any help or suggestions would be greatly appreciated!

Believe it or not, but the speed can be dependent on the browser you are using.

Thread 'Downloading videos files directly from camera via web interface (using other than IE) seems to be capped at *TEN* Mbps'

2025_10_18 UPDATE: This problem still exists with the new T54PRO-ZE ... using both @EMPIRETECANDY and Dahua firmware.

It's very easy to demonstrate. Login to the camera web interface with any of Chrome, Edge, Firefox in Windoze. First, pretty much everything works ... WITHOUT the plug-in ... good work Dahua.

Click the Snapshot button and you'll see the ~10 MBYTE PNG download in a second ... that's 100 Mbits/sec. And try uploading some firmware - 700 MBYTE's takes just over a minute - again, the full wire-speed of 100 Mbits/second is doable bi-directionality.

But how is the browser I’m using related to SmartPSS Lite? I’m downloading it directly from the program, not from a browser.
 
Oh sorry I thought you said you couldn't connect via Lite.

It looks like your data is going thru the router and that usually is a speed killer with these devices as they don't know how to buffer.

Its not likely the program, its a connection issue 99%

For instance I can download a 100MB clip local on my network in 10? seconds.
Try to do that from a remote NVR and it takes much longer.

I have two remote locations 3o miles from here but 1500 ft apart, same provider and each their won cable modem and router.
One takes 2x longer than the other.

Ok, taking into account that it’s about the internet connection, what would you suggest or recommend I do to be able to download the recordings at a higher speed? Each video takes me about 3 hours to download, and there are 3 videos per day. That’s a lot of time.

Likely you’ll have to pay the provider at the source of the video a business class type fee with guaranteed up/download

But we don’t know yet if it’s your own provider restriction or that at the source…?

What is your internet provider download /upload speed for your service? I hope you are not using DSL like I used to which only have a 5-6MB download speed until fiber was available in my area and increased to 500MB.

Also the SD card you are using also affect your download speed too. You need a fast read/write SD card as well.

I'm used to downloading from NVRs, I hadn't thought about the speed of the SD card. Good point !

I doubt you could buy a (micro) SD Card these days that is NOT capable of at least 10 MBYTES/sec ... and therefore able to saturate the 100Mbits/sec Ethernet connection. So that is NOT a bottleneck!

BTW, as someone who did the referenced post, an easy "end-to-end" test of your connection is to upload firmware ... which goes at the maximum 100 Mbit/sec. You can ALSO do a "browser snapshot" ... as the PNG's come in at about 10 MBYTES ... and they download in about a second .... so again, the expected maximum rate.

So clearly "everything" is capable of 100Mbits/sec ... but you use any browser to download the .dav video files directly from the camera, it crawls along at a pokey ~1.5MBYTES/sec ... so there's some sort of goofiness that limits this - be nice if it was fixed.

I suspect SmartPSSLite is hitting that same limitation. Removed per @bigredfish comment below.

I’m not a network savvy guy.

So why would SmartPSS be able to download a 100MB video from my LAN NVR using say a 4K 16,384 recorded stream in less than 10 seconds but a 2MP recorded 20 MB video from a remote NVR in more like a full minute +?

Doesn’t seem like SmartPSS is the bottleneck?
