Title: Transfer from MicroSD slow
Post by: Pripyat on March 30, 2017, 10:21:15 AM
Even when connecting directly to the camera via ethernet the best transfer speed I can get is 230kb/s on a modern i7 PC.

I tried different microSD cards and it didn't have any effect. All were class 10 or better, differing brands. Pinging the device yields <1ms replies yet the transfer speed is painfully slow.

Is this typical?

What Mfr and model is the main host router?
Turn off all anti virus and firewall programs on PC while testing.

There is no router - I am plugged directly into the camera. It isn't the PC - I have tried two different PCs and both transfer at 220-230kb/s. I am keying in the camera IP into a browser, then browsing to the SD card, then selecting a file to download onto the PC.

I set a static IP on my machine and also have a static IP set on the camera. To reiterate, Ethernet cable goes from PC directly to camera. I have also tried going through an unmanaged switch with the same result.

I was using wireless to begin with but the transfer speeds were even slower, likely due to signal strength issues. I hard-wired expecting the speeds to increase but they only got slightly better.

Can you connect using Windows Explorer and do a xfer there?

I'll try this as soon as I figure out how to. It may be tomorrow before I have time to sit down and play with this again.

That's fast!  There's no gigabit on these.

Is that about expected speed for SD card file xfer?

I tried to discover the camera in windows but can't figure out how. Can you direct me to some instructions?

This would be a lot easier than going through the webpage.

Note that he's reporting a transfer speed in kbps, not mbps.

I downloaded a single video file from a DCS-2230 of "Size 51484", and IE 11 reported around 2.4MB/s.

Which is 2400KB/s. or 19200 kb/s.

I really doubt the original poster is getting 230 kb/s. 

I don't have a card in my 2330L to test.  But downloading multiple files from the 2230 will over load/cause frame loss if streaming, and if wireless - the camera will give up the ghost and restart.

I have three of these cameras on my local network. All have the same speed issue. I have transferred files on three separate PCs with two different OSes. The screenshot was done with a direct connection to the camera, no network at all.

It does look slow.

I can't get any of the PCs on the network to see the cameras as a media device. Any tips? Is there something on the camera that has to be enabled? Or anything on the PC?

Be sure uPnP and uPnP Port Forwarding is enabled on ALL cameras.
Make sure uPnP is enabled on the main host router and PC as well.

I can see the device in windows now but it isn't recognized as a media device. It is listed as "other devices".

Why does port forwarding have to be on if I will only be accessing the camera on the local network?

Post by: FurryNutz on March 31, 2017, 11:11:49 AM
uPnP is how devices are see and determined to be media devices in Windows. If it's not enabled, then Windows may not recognize it as a media device.

It does look slow.

However, at least it is actually KBps and not Kbps as he originally wrote.

The instant I enabled upnp I had the camera pop up in Windows. But, it is recognized as "other devices".

Any tips on getting it recognized as a media device? Currently I'm unable to access the camera through Windows - Only able to view the camera properties.

Apologies on mixing up the units. I should know better..

I've tried on two Windows 7 machines and one Win10.

While I'm here - I've had issues with the cameras dropping off the wifi. Do you guys have any recommendations or things I can try? I've tried setting static IPs on the camera outside the DHCP pool but I still lose the cameras after some amount of time. Cycling power on the cameras themselves always fixes the issue.

I tried having them automatically reset at midnight but that made the issue worse.

What wireless modes are you using on the main host router?
What Mfr and model is the main host router?
What channels are you using on the main host router?
How many cameras and devices do you have connected to the main host router?
Any other wifi neighbors near by? How many and what channels are they using?
Ensure uPnP and uPnP Port Forwarding is enabled on ALL cameras.

Even when connecting directly to the camera via ethernet the best transfer speed I can get is 230kb/s on a modern i7 PC.

I get a download speed of between 250 to 290 KB/sec using Firefox to download 4.5MB .mp4 files over WiFi from the SD card in my DCS-2330L.
