How to improve lag time for WVC-210 for remote viewing

Hi,
My 2 camera WVC-210 is all setup. When I operate the camera remotely, I instanly hear the lens motor operate but there is aproximately 30 to 60 seconds lag time before the video is refreshed. This can be very frustrating at time. I have both cameras set up wireless.
Can somebody first explain to me why this happens and what I can do to improve the lag time. Perhaps I should tweak some settings. I would also consider buying what ever gadget is needed to make it work better.
Just to review my problem. Sound is instant but video lags.
Thank you all in advance,
Rod

May I ask if this is also happening if you’re not viewing the camera remotely? Have yoy tried adjusting the sensitivity of the WVC210?

How to get execution time for a view inside procedure ?

Hi,
I want execution time for all the views in my database. I tried "execute immediate" but it does not seem to work.
It is not waiting to complete the execution of view to go to next step.
If I am executing the same statement in sqlplus, it is displaying correct time.
Here is my code:
Begin
output_file := UTL_FILE.FOpen ('RECORDING',v_FileName, 'W', 32767);
Open viewcur;
Loop
Fetch viewcur into v_view_name;
     Exit when viewcur%notfound;
     SELECT to_char(systimestamp,'DD-MON-YYYY HH24:MI:SS.FF') into v_start_time from dual;
     v_stmt := 'Select * from ' ||v_view_name ;
     Execute Immediate v_stmt;
SELECT to_char(systimestamp,'DD-MON-YYYY HH24:MI:SS.FF') into v_end_time from dual;
v_record_str := v_start_time||','||v_view_name||','||v_end_time;
     UTL_FILE.PUT_LINE(output_file, v_record_str);

How to improve the speed for backing up files to time capsule via in hose wifi?

via in hose wifi?
Use a bigger hose??
House??
Need to spell this out a bit more..
But speed via 2.4ghz to the TC is restricted by Apple to max 130mbps link speed.. much slower actual transfer.. latest TC and laptops can do 450mbps on 5ghz but you need to be up close.. so place the TC near the device using it.. and force 5ghz connection by using a different name for 5ghz network.

How to increase the time for detect a device down on Prime 2.0

Hi,
I would like to know how to increase the time for detect when a device has lost connection, currently I monitor several stand alone Access Points that are paleced on differents locations connected to prime through 256 Mbps Links, so when the location has very high bandwith utilization, an e-mail notification about the unreachable Access Point is sent, but if we check te reachability, the Access Point is reachable, and we don´t want to receive to many of this notificatios,
thanks for your help

Go to the Console, Select the server --> configuration --> tuning tab,
Stuck Thread Max Time and Stuck Thread Timer Interval (give your required time)
This will definitely increase the Stuck Thread time interval.
or
by using work manager also you can define Stuck Thread Max Time interval by editing deployment descriptor file
<work-manager>
<name>wm_name</name>
<max-stuck-thread-time>30</max-stuck-thread-time>
<stuck-thread-count>5</stuck-thread-count>
</work-manager>

You can activate Time-Dependent Publishing Service on your XML form and once the Lifetime of Documents is over then the document is not visible to users.

How to create transaction code for maintenance view

hai friends,
i hope every thing goes good.
i have doubt, how to create transaction code for maintenance view. I created view for tranperant table and now i want to create transaction code for the view.
i tried and i donot know the screen number and program name and where can i give the view name.
if any one know please post in details.
thanks in advance.

Hi Elam,
You need to create a "Parameter Transaction".
What this means is that you will have a transaction (let's call it "ZMAINT") which calls "SM30" and passes in your table name.
Go to transaction SE93 and enter your new transaction code. Enter in the Tcode description and choose "Transaction with Parameters" (it shouldbe the last radio button).
Enter in the default transaction "SM30" and tick the "Skip Initial Screen" check box. Hit Enter.
Now scroll to the bottom of the screen and you will see a Table Control where you will need to enter in the values to the SM30 selection screen.
Because you hit ENTER, the program will have loaded in the Selection Screen parameters into it's memory. Hit the drop down for "Name of Screen Field" and select "VIEWNAME" and then enter in your Z Table in the "Value" column.
Now go to the next line and hit the drop down and select "UPDATE" in the "Name of Screen Field". Enter in a "X" in the value column.
Now save the transaction and there you have it.
Hope this helps.
Cheers,
Pat.

Help networking a Security System DVR for remote viewing

Hey,
I am trying to network my Security System DVR for remote viewing but cannot seem to get it working. I have read some post on this site as well as many others and followed instructions to the T but to no avail.
Here's what I've got:
Linksys WRT54G2 V1 connected to a modem.
My DVR has 3 settings for networking:
-PPPOE
-Static
-DHCP
On DHCP, The DVR automatically sets these settings:
IP Address: 192.168.1.100
Subnet: 255.255.255.0
Gateway: 192.168.1.1
and then the DNS is the same as the one on the "status" area of the router settings...
Port: 10000-10020
I set up port forwarding for 192.168.1.100 for port 10000-10020 selecting "both"
If I pull up the "DHCP Clients Table" it shows the above IP Address but with no name....and the MAC address is something like ee:ee:ee:d4:03:5f.
I have tried to change the DVR to Static and do everything manually but thats not working either.
I created a Dynamic DNS with goddns.org but the DVR seems to have its own one built in that you cannot change. (at the bottom of the network settings it says something like "URL: 123484984.goddns.org----Status: OK." But when I try to type that in the address bar of IE it goes no where.)
I hope someone can tell me why its not working.... It was working when we first got everything set up...then it stopped. then I messed with it and got it working but didn't know what I did. Now its broken again and I don't know what to do.
-Ian
PS. When I am connected to the router via LAN cable and I type the internal IP Address assigned to the DVR by the DHCP (192.168.1.100:10000) it brings up the DVR menu perfectly. But when I try to log into it from a different location...with the external IP address...thats when I have trouble. I do not think my external IP has changed since I got this router set up.
Any help would be awesome.

Hmmm... Did that and I can't seem to get it working still. Whats weird is that as long as I am connected to the router...I can access it through the internal IP address.... (if using DHCP its 192.168.1.100:10000 and if using static its 192.168.1.99:10000)
Those both work when set up on DHCP for the first and Static for the second. But as soon as I type the external IP address with the port it doesn't work. Its like there is a firewall OR the port forwarding is not working. But everything on the port forwarding page looks good... Its enabled, set on Both, correct port range... 10000-10020...
Any Ideas?

How to execute lag time only for once

Dear Friends,
I want to on and off my heaters only when some X condition is fulfill.

For that kind of timing the Elapsed Time function works well. Set it for 5 min, keep the Reset line True until condition X, then wait for it to time out. The benefit of this function is that it keeps counting through loop iterations, so you can put it in a fast loop. Read the Time Elapsed? output to trigger your heater. You'll need a little additional logic to keep the Reset line input to what you want, but that shouldn't be too hard.

How to get remaining time for baton after setting timeOut property

Hello,
Is it possible to get the remaining time for baton after setting timeOut, or do I have to maintain a separate Timer for that?
Been following this excellent tutorial here http://tv.adobe.com/watch/adc-presents/create-shared-forms-in-livecycle-collaboration-serv ice/

Thanks Nigel, before reading your reply, I came up with something like this, but it seems extending the Baton class is not enough, as I would need my own BatonProperty as well that uses this extended Baton class...
Also attempted to get some help here http://stackoverflow.com/questions/7116814/actionscript3-lccs-how-to-access-property-paren t-class-protected-var/7116882#7116882
Could this be made into a feature request for Baton and BatonProperty, se we could easily get the remaining time please? I guess I can wait for a future release.
/custom as file /
package com.mysite.BatonExtender
     import com.adobe.rtc.sharedModel.Baton;
     import flash.events.TimerEvent;
     public class BatonExtender extends Baton
          public function BatonExtender()
          super();
          _autoPutDownTimer.addEventListener(TimerEvent.TIMER,countDown);
          trace("CURRENT TIMER:"+_autoPutDownTimer.currentCount);
          trace("BATONEXTENDER added");
          public function countDown(p_evt:TimerEvent):void {
               trace("TRACING START countDown....");
               if (_autoPutDownTimer.running) {
                    trace(_autoPutDownTimer.currentCount);

How to reduce processing time for ResultSet getter methods

In my application, I have the following code.
query = .....;
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
var_1 = rs.getString(1);
var_38 = rs.getString(38);
The query generates 35,000 rows. It is running slowly. I checked all the code, it turn out that this WHILE loop runs the slowest. Does anyone know how I can improve the performance for this issue?
Any advice or suggestion will be appreciated.
Thanks in advance,
aloe9451

Now the slowest one is the while loop which get 38 columns.
We do have the requirement pulling 38 columns for 35,000 rows.The short answer: bandwidth isn't infinite.
The long answer:
35,000 rows by 38 columns, by 10 characters per column equals a little over 13 Mb, not counting protocol bytes. Adjust this upward if your fields are bigger, but I don't think you can adjust it downward very much because those protocol bytes are important.
Running FTP between my desktop computer and one of the servers here, I get a tad under 3 Mb/sec transfer rate. So, assuming that your network has similar speed, your 13 Mb of data will take no less than about 4 seconds.
However, FTP is an efficient protocol: it's just streaming bytes as fast as it can, and writing them to a file. Processing a result-set, on the other hand, is synchronous: even if you batch rows, the server still waits for the client, then sends some data, then waits for the client. THen there's the cost of client-side processing, which is going to be significant simply because you're doing close to 1 million method calls.
So yes, for your data size, 7 seconds is very reasonable. But no, for a web page, it's unreasonable ... but so is displaying all that data.

How to improve the performance for integrating third party search engine

hi,
I have been working on integrating verity search engine with KM. the performance for retrieving search result totally depend on how many search result returned, for example if there is less than 10 records, it only takes 3 seconds, but if there are 200 records, it takes about 3 minutes, is it normal? anyway to improve it? Thanks!
T.J.

Thilo,
thanks for the response, would you recommend some document for configuring KM cache service, I did change memory cache, and also dynamic web reposity, whatelse out there that I can change? right now, I have one instance(EP6.4 sp11) works well, it returns 200 records from Stellent within 6s. But when I put this KM global service on EP6.0 sp2 (our current system) it takes about 15s. I am not sure is this because of different EP version, or something else. I have tried my best to slim down SOAP component from Stellent. I don't think anything else can be done from that side anymore. before I changed the SOAP, it tooks about 60s. just wonder what else I can do on KM side to improve it performance? Thanks!
