I see the 1.02_b5 as the latest FW, but the dlink.com support website still has v1.01_v7 (Sep 10 2013 date on the zip file). 1.02_b5 has bugs, so did they pull it from dlink? Latest is supposed to be greatest, but is it?

The firmware is posted in multiple locations on sites maintained by D-Link USA -- unfortunately the firmware versions on each of these locations are not necessarily in sync with each other. The latest firmware is posted on http://mydlink.com/support (http://mydlink.com/support), while www.dlink.com contains earlier iterations of the firmware. For future reference, the mydlink.com/support site seems to be updated more frequently and sooner than the main website. You shouldn't read anything into the fact that mydlink.com/support and www.dlink.com contain different versions.

To further confuse matters, I sometimes post firmware from other sanctioned D-Link sites that are published for worldwide distribution.

Hi forum,

I'd like to see more robustness regarding the connection to the FTP server. If my camera is close to my access point, all motion detected vids are uploaded to FTP server just fine, and are perfectly playable. If I move the camera further away (where I need it to be), the camera will upload either 0KB .avi files or fullsize .avi files (about 2,3 MB with my settings) which are not playable by any media player.

The WiFi signal is not weak where I need the camera to be. My smartphone reports 3 out of 5 bars on WiFi when put where I need the camera, and the DCS-933L webinterface including the live monitoring works just fine. So I think it may have to do with FTP timeout values or other parameters that affects robust upload.

I have the exact same problem. And also constantly during night mode. Not only during the switch.

Motion detection is useless with this bug. Is this being fixed.

Only false detections. I cannot make it work correctly.

Recent firmware releases on other D-Link Cloud cameras contained a fix that improved the judgement logic used for the day/night transitions. Hopefully that improvement will soon work it's way into the DCS-933L as well.  :-\

What you are describing sounds like noise in the video feed that's triggering motion detection events, not something related to day/night mode transitions.

No sound involved. Sound detection is off.

I placed the cam in a dark closet to test it. All day false motion detections. It has nothing to do with day/night switching. I simple got mails during normal operation. I want to send the photos so you can see. You can see all kind of scrabled lines and blocks. The movie is flickering black for a very short moment. So this is no normal behavior and has not to do with switching between the day/night mode.

How can I give you the images? So you can check.

When I said "noise", I was referring to image artifacts (e.g. lines) that the camera is most likely interpreting as movement.

Possible causes for these artifacts may include interference from other electrical devices or the power lines themselves. Try placing the camera elsewhere to rule this out. The only other additional recommendation I can offer at this point is to save your camera settings as a "Configuration Settings" file (option exists in the firmware web UI); reset the camera to the factory default settings; reinstall the firmware; and upload your settings from the saved file.

The cam was reset to factory defaults after I removed it from "mydlink.com". I use it without cloud now. The cam is placed in the hallway against the wall now (I did this yesterday evening). I got the false detections during my test day in the dark closet (yesterday during the day). But I am not the only one. Please read the posts. I don't think it has anything to do with interference from other electrical devices or the power lines themselves. Please inform if there are more complains with the same problem and if they are working on an update. I need to know if I must wait for an update or return the cam. I reported this issue twice at the dlink support site but no reaction. Can you please inform...

I tried again, wall mounted away from electric things. I tried night mode again. Cam is wired, no wifi, no extender, only cam.
And again I got scrambled photos. False detections. Am I the only one? Now I am trying day mode but the hallway is dark so I cannot see a bit.
The scrambled photo is generating the false detection, is has nothing to do with movement.

Pease let me send the photos and inform for me.

I keep you informed about the day mode.

Thanks.

I tested this night with MJPEG (320x240) and No False detections!!!

I think the problem is H.264! That's also why the 932L is much better.
Since the start I was using H.264 (640x480). I think it's a problem with the H.264 codec or the resolution!

I will test further combinations later.

Maybe you can check some things too.

My video has always been set to MJPEG (640x480) and I continue to get false detections.

Can you see scrambled lines and/or blocks on the photos and videos? My (6) photos contains big scrambled lines and blocks in H.264 mode.

If you don't see scrambled lines and/or blocks I think it's really a motion, maybe some light or other things.

The scrambled lines and/or blocks on the photos are very easy to see, very big. Until now only in H.264 mode for me.

Please tell me about the photos. I want to solve this issue....

Last night in MJPEG (640x480) Jpeg Quality: High and Frame Rate: 30 -> 3 false detections!! >:(
In the movie I can see the a few frames flickering. A coding error -> for sure!

Conclusion: I guess the higher the Resolution and/or Quality and/or Frame Rate the more problems. The cam has problems with encoding video. H.264 needs a lot CPU power so I guess this is not working fine. If I run in MJPEG (320x240) Jpeg Quality: Low and Frame Rate: 15 it's working much better.

So if you have false detections: Please test with Low Resolution and Low Quality and Low Frame Rate.

Please communicate your experiences. Thanks.

Another vote for problem with H264 implementation.  The stream itself is choppy, even if buffered for 10 seconds, and using lower resolution/frame rates via good wifi connection (no prob with mjpeg though, besides lack of audio).
Does D-Link really think everyone wants to use their cloud service crap, this thing would be much more reliable with a FFMPEG stream option, rather than this H264 in an flv container bull!
I'm guessing this unit just lacks the necessary CPU...

Yes, and even MJPEG in 640x480 is not working. Also strange black frames and scrambled frames.

Now I run in in MJPEG (320x240)
Jpeg Quality: Low

This is working much better.

But who want the lowest quality???

Hi, another user with the same problem. False triggers with no motion in the image whatsoever. Just sometimes artifacts in the captured images that remind me of an old TV with a horizontal sync. problem. I even tried a replacement camera, the results were identical. Tried using it two different locations to eliminate the likelihood of electrical noise being the cause. I doubt it is now.

I've tried reducing the image resolution as suggested, but now when I try to view the camera on my app, it crashes the app. Set the resolution back to 640x480 and the app works, but I get false alarms again.

This product really isn't up to the standard I expected. Hope that Dlink can come up with a solution.

Hi,

I hope they are able to fix this issue but when......

IP Cam Viewer on Android is working fine with all resolutions. I'm not using the cloud.

Low resolution (320x240 MJPEG, Jpeg Quality: Medium, Frame Rate: 15) works fine but it's ridiculous that it's not possible to use higher rates.

I wouldn't call this an issue as it's by design to manage traffic. When viewing a DCS-933L via mydink on a local network the maximum resolution is 640 x 480, while viewing live video via mydlink remotely the maximum resolution is 320x240.

Same problems here with distortion: https://app.box.com/s/uuzmdwqhscga7y7hbf9o (https://app.box.com/s/uuzmdwqhscga7y7hbf9o)

I've already added some ferrite to the power-cable to exclude RF interference picked up by the power cable:

For the firmware engineers some hints to what could cause these kind of effects:
- DRAM hardware issue? Unlikely, there entire device would probably crash then
- Sensor interface timing? Unlikely, there is also timestamp/overlay data in the corrupt image
- (Non)Atomic framebuffer access? Could be.. The frame is overwritten by a new one. The fact that the problem disappears with lower framerates can confirm this.

While H.264 is enabled, try setting the motion detection sensitivity to the lowest setting and incrementally increase the sensitivity as needed and see if that can compensate for any image noise.

The false detections has nothing to do with the sensitivity. The cam is generating scrambled blocks and lines with all sensitivity values. Only the lowest MJPEG resolution and low quality values are error free.

While motion detection sensitivity settings may not be the root cause of these particular false triggers, the sensitivity settings can impact how the camera reacts to them. Again, by setting the sensitivity values to a very low value and incrementally increasing, you can try striking a balance where the camera effectively ignores the image artifacts, but is sensitive enough to detection motion. I'm posting this as a suggestion for users to test.

With all respect but this idea is completely useless since the scrambled blocks and lines sometimes fills half of the view. Did you ever saw the problem? I can give you video and photos. I asked many times for experiences from D-Link about this problem and also about the other older 932 cam. All without any reaction. If you think I still have any kind or trust in D-Link, the answer is zero. I bought a cam to use the specs D-Link is giving. I cannot use it the way D-Link is telling the whole world. I only can use the lowest and baddest quality. Isn't it terrible. You think I ever buy a D-Link thing again! Never. The baddest thing is the complete lack of support. >:(

If you think I still have any kind or trust in D-Link, the answer is zero. I bought a cam to use the specs D-Link is giving. I cannot use it the way D-Link is telling the whole world. I only can use the lowest and baddest quality. Isn't it terrible. You think I ever buy a D-Link thing again! Never. The baddest thing is the complete lack of support. >:(

You did that before...

Who is going to pay the phone costs. More expensive than buy a decent cam from another brand.
What kind of service is that. Ever heard of support via mail or internet.

Sorry. >:(

D-Link USA technical support is a toll free number (i.e. no phone costs) for users calling within the United States. D-Link also offers email-based support, but I find the live phone support more responsive.  ;)

 :( I used to be a very happy D-Link customer... until the time of this last firmware upgrade that has totally screwed up my home security.  I currently have 10 dlink IP cameras.  This includes the 932 and 933 models.  The 932 models do not show any issue (as they do not relate to the same firmware).  The 933 models are the ones where I see this issue... false detection.  I have also bought new models which show the same issue.  Occurrence depends on model but 3-5 times per hour on average.  You multiply this by days and my 7 models and this is no longer acceptable.

I have tried the d-link technical support thru telephone and they have been of no help.  It takes over an hour to explain the entire situation and then they give you a case number at the end saying they cannot resolve the issue over the phone.  But that they will let someone over there know.

What I would recommend is that we spread the word... to be specific relay the facts.  Customers buying this product should know what they are getting.  As I got my products from Amazon, Best Buy and Office Depot, I will shortly relay my feedback thru these sites.  I recommend everyone reading this to do the same if they are experiencing this same issue. 

At the same time if dlink does fix the issue we need to be fair and relay this in all of the sites where we post.

In the US, I guess it is the Mass Media that will drive improvement.

Again, I used to love dlink...

Do the image/video captures from the false detections contain anything that would indicate the cause? i.e. image artifacts, shifting, etc... Please elaborate.

The issue is the same as the ones given by others. 

* Issue is occurring for only DCS-933L
* There are constant false detection notice that are sent
* There are two types of photos which I receive:
   - Those with the 6 photos that show no difference
   - Scenario where of the 6 photos one of them shows a "static" type image
     often where the photo left side is showing on the right side.
* This was not occurring earlier as I was able to use this with no issue.  The only
   change has been in the firmware.
* I have tried repositioning the units.  The DCS-933L has this issue where when
  I position a DCS-932L in the same location there is no issue.
* This issue does not occur for the DCS-932L which works perfectly fine
* I bought a new DCS-933L yesterday from Best Buy to see if it was unit specific.
  The same issue is occurring for the new model.
* I have also bought and changed my Netgear router after the detection of this
   issue to the new D Link router 868L.  Issue does not change.
* I have conducted the following as well: Default to factory settings, upgrade of
   firmware, the issue continues to occur.
* Have changed setting from H.264 as well as to MJPEG.  Issue continues.
* The issue occurs for all three of the DCS-933L which I have used.  Two from my original
   purchase around June of last year and the other which I bought yesterday at Best Buy.

This is a very big issue as if I just use my previous setting, where I would only receive motion detection about 2-3 times a day has multiplied to close to 100 for each camera.

Hope D-Link can work this out and fast.

Let me know if you require additional info.

It's nice that Dlink is aware of the issue, probably every camera is affected with this... The next step is to resolve this issue with a firmware update:
- Track the source of the issue (reproduction is not that hard) -> Is anybody working on this?
- When issue is in software -> It can be fixed with a FW update
- When issue is in hardware -> Make a work-around (e.g. require at least 2 frames of motion)

A few days ago I completed a test where I successfully replicated this issue on a DCS-931L.  Over a five day period, I encountered one instance of image artifacts: 7 images over a 2 hour period that caused false motion detection triggers.

During the five day period, the DCS-931L pushed approximately 11,500 screen captures to FTP storage. Except for the 7 images in question, all 11,500 images were generated from valid motion detection events. This is not to discount reports from other members stating that they've encountered this issue with greater frequency. This inconsistency leads me to ask the question: Is the cause firmware, environmental (i.e. some form of interference), or hardware?

???  :-*  ???

I passed my findings, as well as all of the related DCS-931L and DCS-933L links, to D-Link.  I'll post back if I hear anything.  ;)

As an FYI, aside from posting in this forum, D-Link often escalates issues based on the quantity of reports they receive through their support desk. A large volume of tickets with the same issue raises a flag. You may want to log this issue with technical support for that reason alone: 1-888-851-6464

Here is some additional info relating to my tracking of the issue.

I set up last night 5 D-Link Cameras:

1) DCS-933L Unit 1 Bought in May/Jun 2013 Positioned Outside
2) DCS-933L Unit 2 Bought in May/Jun 2014 Positioned Inside towards ceiling
3) DCS-933L Unit 3 Bought Just last week Positioned Inside towards ceiling
4) DCS-5020L Positioned inside room
5) DCS-932L Bought in May/Jun 2013 Stairs

Changed settings to all of these (excluding DCS-932L) to be

H.264: Res 640x480, 2Mbps, 20 frames
MJPEG: Res 640x480, Jpeg Quality: High, Frame Rate: Auto
Default View Mode: Image
Motion Detection Sensitivity: 40%

Conducted test from 9:15PM to 10:30AM (US Central Time  :))

I then EXCLUDED all notifications that showed motion or light change in the photos. 

Here are the results:

1) DCS-933L Unit 1 (Outdoor)
    24 false motion detection notifications
    1 of the false notifications included static image

2) DCS-933L Unit 2 (Study Ceiling) 
    15 False motion detection notifications
    3 of the false notifications included static images
    2 of the 15 may be due to very slight light change

3) DCS-933L Unit 2 (Dining Room Ceiling)
    9 false motion detection notifications
    2 of the false notification included static images
    1 of the 9 may be due to very slight light change

4) DCS-5020L (Side view of non-used game room)
    2 false motion detection notifications
    Note: prior to dropping the sensitivity from 50% down to 40%
    false notification was occurring more frequently.

5) DCS-932L (Stairs)
    0 false motion detection notifications.
    All were actual motion notification and there were no notifications during the night.
    Note: The DCS-932 settings are currently as shown below:
    JPEG (only selection) 640x480, FPS:Auto, JPEG Quality: Very High, View Mode: Image
    Motion Detection Sensitivity: 63%

Additional Note:
* Previously I had to set my motion detection sensitivity at about 60-70 percent in order to detect proper motion.  Based on my findings on the current firmware/model seems to need this dropped significantly lower in order to properly operate.  I still need to test the sensitivity based on the 40% to see if actual motion can be captured correctly.  If there is a change in sensitivity when comparing previous to now, DLink should let their customers know.

* I have started a second test run setting the percentage to 37%,  Will update once tested.  During the first hour I have received 5 email notifications from only Unit 1 (DCS 933L Outside scenario).  Of these 1 of the notices has a static image.

Will add more as I conduct further testing.  Seems though that his static image showing up indicates a problem with either the hardware or firmware of both.

Let me know on what you detect thru these findings.

Just as an additional note on my previous findings.  The false notifications do not include the actual motion triggered emails.  The numbers are the count of cases where I could not detect any change in the image photos or where there were static images included.

Based on further investigation, here are some factual info to add to my previous comments.

The DCS-933L models have EXTREME sensitivity.  In my following tests, I lowered all of the motion detection settings to 25%, the lowest you can set without going into Advanced Settings.  This was still too sensitive.  By lowering the setting to about 10-20% has reduced the number of emails (with photos) significantly but where there will still be non-motion notifications.  It is totally ridiculous as I cannot set the motion sensitivity level from the main setting screen as it will not allow me to move it to the level required as it is so low (lowest allowed is the 25%).

Note that after adjusting my DCS-5020L to 30% I have had no non-motion triggered email issues.  I have this issues only with the DCS-933L units.

The email notices are supposed to be 300 sec apart but this function is not working.  This is the same for all of my 933L models as well as for the 5020L model.  There seems to be a flaw in the firmware.  For quite a few of the notifications each day, they come with about 3-4 emails which all come in within the same 1-2 minutes.  This occurs in many cases when the static image email is sent but not always.

I also put in some AC noise filters for the cameras which I was testing to see if this would reduce occurrence.  This did help reduce some of the non-motion notices but my guess is that the sensitivity is still too extreme and so it may be where the noise filter is helping to band aid existing sensitivity issue.  I have DCS932 units which work fine without the noise filters.

The occurrence of the non-motion triggered notification is about 19 within 12 hours for the 3 DCS933L units.(excluding the motion triggered notices).  Of these about 50% have the static images.  The occurrence of the static images has not really changed compared to previously when I had the sensitivity set to be higher.

In summary, my assumption on what DLink needs to get fixed are:

* Motion Sensitivity being too sensitive for the DCS933L
* Static images occurring for the DCS933L
* Multiple emails being triggered within the same minute (although the setting to allow this compared to before would be good).  This in my test is not just for the DCS933L but also for the DCS5030L.

The 933L seems to be a very bad and unacceptable model compared to the 932L.  I hope that DLink is able to fix this.  I am returning two of the units tomorrow to Best Buy.

when you say "static images", are you referring to screen captures with image artifacts (i.e. distortions or shifted frames)?
Title: Re: DCS-933L - Firmware v1.02b5 - Comments & Observations
Post by: Sad User on February 24, 2014, 05:04:30 AM
Yes.  These are images with the left shifting to right or right sometimes to left and with the entire screen looking like pieces of brick due to digital distortion.  This only occurs for one of the six photos sent when the issue occurs.

Yes, the corrupt image seems to be triggering the motion detection event and then the remaining "normal" images are generated as per the number specified in the user configured Emal/FTP settings.

Post by: Sad User on March 01, 2014, 09:20:51 AM
Some additional input and assumptions.

* The "static" photos seem to trigger the emails but could the other emails that are received which are not triggered by motion detection be triggered by these "static" occurrences?  As the photos are only every 0.5 to 1 second, could the static have occurred between the snapshots?  If this is the case even though the "static" email photo may not be included in the 6 photos received,  they could still all be triggered by this "static" image occurrence.

* As I remember someone else mentioning, I tried connecting the units thru LAN hardwire (Cat5e cable) and they work just fine.  The issue seems to relate to wireless signals but note that this is occurring only for my 933L units.  my 932L units and 5020L unit when put into the same location work just fine.  So although due to wireless, I believe it is a specific issue inside the 933L.  This occurs for all 3 of my 933L units.  Also note that when I connect through hardwire, I have to readjust the sensitivity back to about 60-70% for the unit to work properly.

The 933L unit is a faulty product.  Although they are currently on discount I strongly recommend that people do not buy.  The 932L (at least the remaining inventory) as well as the 5020L would be a much better choice.  Also the 5020L as it has the pan and tilt can cover for 2-3 of the 933L units depending on where you place it which justifies it's higher price.

I hope D-Link fixes this as I am at the point of considering on switching my entire IP cameras over to another brand even if it is throwing away my entire d-link camera investment.  "Unreliable" is the word that I think of nowadays when I think of "D-Link".

The DCS-931L also suffers from this same issue. The DCS-931L and DCS-933L are identical save the Night Mode.

But I am not the only one. Please read the posts. I don't think it has anything to do with interference from other electrical devices or the power lines themselves. Please inform if there are more complains with the same problem and if they are working on an update. I need to know if I must wait for an update or return the cam. I reported this issue twice at the dlink support site but no reaction. Can you please inform...

Grt.


I am also having exactly same issues.  The false triggeres due to artifacts (they appear either in color os b/W) are happening for me 12-14 an hour which lead me to disable the motion detection. This renders the camera pretty useless ...  What I do not understand is why the 942L has no issue, and the 933 and 931 does?  Is that so complicated for D-Link to release a product consistent among their models?

The DCS-931L and DCS-933L are essentially the same camera with the exception of Night Mode (DCS-933L only). Meanwhile, the DCS-930L, DCS-932L, and DCS-942L are all very similar to each other, but are from the previous generation of D-Link cameras. The hardware from the 931L/933L should not be compared to the 930L/932L/942L.

Again, D-Link is aware of this issue and is working on a resolution. If I receive any updates,  I will post them in the DCS-931L and DCS-933L boards for all to see.

D-Link expanded the release notes for the latest DCS-933L firmware version 1.03b08 (security update). There are additional changes that were not documented in the first set of release notes: DCS-933L - Cumulative Firmware Release Notes (http://forums.dlink.com/index.php?topic=53798.0)

There are two particular bug fixes that leave me wondering if the issue described in this thread was addressed. The release notes entries are a bit ambiguous:


I'm not sure how to interpret this. . .  :-\

Have any DCS-933L owners who updated with the security update noticed any improvement on the image artifacts discussed in this thread?

I can tell you that the v1.03b08 is much better. I'm running 640x480 - H.264 - 1.5Mbps - fps30.
I mail my motion detected (40%) movies, 8 seconds, to keep the avi size acceptable. And I upload the motion detected movies (15 seconds) to a FTP server. Until now no false detections.  ;D

I think they did a good job. Unfortunately without any communication during the development process. I still think that's a very bad think D-Link!!!! We were waiting 4 months without any status update.  >:(

Thanks for your continued feedback. I hope other DCS-933L owners post their experience as well to validate that everything has in fact been resolved. I'd feel more confident proclaiming success with at least three people offering similar results.
