Export/Import comes to Android in v1.8

30. August 2014 19:55 by Jerry in Android, IP CAM

Before today's update (IP CAM Controller Android v1.8) if you want to back-up your camera, the only option is to use share function to share your camera via a virtual hyper link one by one. The good news is that now you can backup your camera in the same way but this time you can export all cameras. Let's see how it works.

 

 Step 1, select "Export Cameras" from menu

There will be a warning after that, tap OK (if you are ok:))

 

Step 2. Then it will show up a list of apps that able to send your backup, in this case, I'm going to go with Gmail

After that, it just like composing an ordinary email (with Gmail of course), please note that the exported cameras are inside an encrypted hyper link (at the end of the email),as well as a file attachment with your setting in plain text. And that's why you have to be caution whom the email is sending to - because whoever have the file and installed my app will be able to access to your cameras.

 

Step 3: Import. Open up the email, you can either tap on the link in the email or download the file attachment (for Android 4 users only), your phone should be asking how to complete the action.

Just like this:

 Tap IP CAM Controller, my app will promote a warning to ask whether you would like to proceed, as this will clear out all your existing (if any) cameras.

 

That's it. Cameras from one phone could be transferring to another Android device just like that:)

Work around for FOSCAM 9821W V2 audio issue

23. August 2014 00:08 by Jerry in

It's a known  issue that audio is not working on FOSCAM FI9821W V2 even with the latest firmware. More info could be found on this post:

http://foscam.us/forum/fi9821w-v2-rtsp-via-vlc-working-for-video-but-not-audio-t10025.html

If you are interesting in applying the patch as mentioned at the end of the post above, you can download it here and uploaded at patch update:

http://www.jerryhuang.net/ipcamcontroller/FosIPC_A_patch_ver2.x.1.10_1_20140606_150128_rtsp_audio.bin

 

I believe this patch will be shipped in future firmware update eventually, so if audio is working for your camera, there is no need to update the patch.

WP8.1: 想说爱你不容易

8. August 2014 12:42 by Jerry in Windows Phone Development

MSFT is about to rolling out the gorgeous WP81 update - the biggest and the most important upgrade in the history. And that is a nightmare for most app developers like meCry

First of all, for those who are having trouble with the title of this post, please kindly click here for translation. I just couldn't find a better title than that and it's time for you guys to learn some Chinese, LOLCool

When I upgraded from WP7 to WP7.8, I don't have too much trouble and of course less excitement - it was nothing but adding a socket (to some extend:). When it came to WP7 to WP8, I was excited because C++ is available and the app finally support audio. I have done a lot of coding at that upgrade but mostly about new functionalities - I don't have to rewrite everything.

Now, things are getting more complicated and it looks like there isn't much benefit I could have (neither the app user). There are 2 options to upgrade the development from WP8 to WP8.1, let's start with a nice comparison: http://msdn.microsoft.com/library/windows/apps/dn655121(v=vs.105).aspx

There are actually 3 options in above article but option 1 (not upgrading) is out of the table as we want to move on and believe me that's the last option MSFT ever want (they put huge money on the new WP81 but telling you to hold off, no way!).  For the other 2 options let's read a discussion I found here: http://social.msdn.microsoft.com/Forums/windowsapps/en-US/bf855b7f-d7ca-4b73-964f-22ac77f7d4c4/benefits-of-windows-runtime-over-silverlight-in-wp81?forum=wpdevelop

To simply put, there are 2 different WP8.1 in terms of development framework, one is Silverlight 8.1 (SL8.1) while another is Windows Runtime (WinRT, aka Universal app). The latter one is the same framework when you develop a Win8.1 store app for Windows tablets and/or W8.1 desktop (Metro). Although MSFT claims that they are equivalent about everything, the truth is that WinRT (universal app) is being seriously promoted right now while SL8.1 in my opinion is something intermediate during the transition (remember WP7.8 before WP8, sound familiar?).

If I predict above correctly, RT is the future for app development (phone and tablet) on Microsoft's platform, therefore in long term I would like my development to be on that. However, it really means to rewrite the whole app again - not everything, but still a lot including the UI. And it becomes more trouble if your projects have reference to 3rd party libraries (which is very common for even a small project) - they need to upgrade to support that as well.

When I say "including the UI", I mean:

  1. This only apply to WP8 -> WinRT upgrade path
  2. XAML is not reusable, because the UI framework are different between WP8 and WinRT, you may consider things are being rewritten/re-design in WinRT.
  3. There are a lot of UI controls available in wp8 have gone or being replaced. such as LongListSelector (replaced by GridView or ListView or maybe something else), <controls:Pivot> becomes just <Pivot>, etc
  4. If you are porting your WP8.1 app from a Win8.1 app, and if you use lib like WinRT XAML Toolkit, you need to find alternative or wait for future update from the component developer because currently doesn't support WP8.1 just yet
  5. If you are upgrading from a WP8 app, and if you use lib like Coding4Fun toolkit, similar to above, you have to find alternative or wait for update because current version doesn't support WP8.1
  6. Don't forget doing so much will not bring any improvement or new feature to your users, instead, it's very likely to cause some bugs as the changes are about everything: UI, API, etc

 

So what if we go with SL8.1 as MSDN suggests just some changes? It's much less painful (above item 5 is also applicable though) but keep in mind that WP8.1 is new, you might still have a lot of users on the old platform and so you need to maintain development on 2 platforms (if you care those users). As a result, you will have to clone a new set of projects (including the UI project) from your WP8 solution (you will need linked files); and re-target the new projects to WP8.1. After that, any change, especially on the UI, you are likely to code twice. This kind of maintenance will last for a while base on my experience, until WP8 is completely or almost fading out.

I haven't completely decided yet how to upgrade my development for my app, for now, I would rather just sit tight and watchCool

Sensor mode: tilt the phone and camera move

1. May 2014 15:41 by Jerry in IP CAM

A new cool way of controlling your camera had been introduced in the latest updates: sensor mode. After turning on the sensor mode, the app will use your phone's Accelerometer Sensor to detect which direction you are tilting and so trigger a Tap to Center (or Tap to Move if your camera doesn't support TTC) command.

Tapping the "direction" button to activate sensor, hold your phone horizontally, then tilt to a direction the camera will move toward that. The above video is using WP8 as sample, the feature is working the same way in other platforms (Android, WinRT). In android, to activate sensor mode, should tap the "compass" icon instead:

 

This is actually interesting and it extends a lot of possibilities. Imagine that you can put your phone on something constantly shaking and so trigger a random patrol on the camera. Another idea which I haven't think it through is that if you have something more advanced like a robot-car, so that your robot could somehow control another camera.

 

The new share feature in WinRT and WP versions

15. April 2014 12:27 by Jerry in IP CAM, Windows Phone, Windows Store

With latest update for WP8 (v3.3.5) and WinRT (v1.3), a camera setting could be shared between these 2 platforms, with either a link or a file attachment. See follow scenario as a sample:

 

On your tablet, activate bottom command bar in single view screen, then choose "Share via File" (or Share via Link if you like)

 

A share charm will be showing on the right hand side:

 

Choose Email to send the file in email attachment; In fact, if you had installed other app with file-sharing ability, there will be more options there.

 

After that, just like sending a regular email, you can type in extra info for the recipient. Just don't forget to tap the "send" button on the right upper corner:)

 

With IP CAM Controller installed on recipient's phone or tablet, simple open up the attachment, IP CAM Controller is able to read the encrypted content from file and open a view screen immediately. With this approach, the recipient doesn't need to input any configuration about your camera (such as IP, port, credentials, etc), they are all inside the small file you sent over.

 

 

Note for using "Share via Link"

The share by link is working similar except that the camera info is inside a hyper link (aka deep link). The link following this format:

ipcamcontroller:view?v=4&cam=xxxxxxxxxxxxxxxx

There are 2 critical parameter here:

v=4: version is 4 which is the newest version number by far;

cam=... : for different version, it works quite differently. For version 4 specifically, it's a shorten URL like http://goo.gl/abcdefgh; for version 3, the cam value is a very long string which normally over 600 characters;

The phone version supports all versions while the WinRT only support version 4.

IP CAM Controller for Windows 8 Store is on its way

15. March 2014 17:24 by Jerry in IP CAM, Windows Store

Finally, we are hereCool

The first release have just been submitted to Windows Store for verification. It might take a few days if I'm not breaking anythingEmbarassed.

 

The first version is always challenging, with a lot of things need to be done and a lot of testing. I admit that there are only a few screens in this version with "multi-view" is missing:( However, the tile experience in this version is great in my own opinion, I guess this is because the device has much large screen space than the phone version (obviouslyLaughing), here is a peek of the live tile on my Surface 2:

 

There are 3 IP CAM Controller tiles in this screen, you will notice there is an app icon at the bottom-left corner. The smaller 2 are camera tile - by tapping them will enter to the single viewer screen directly (same as WP8). While the larger tile is the app's main tile, for now, the app supports 4 different size: Large square, Wide, Medium square (same size as camera tile) and Small. Let's have a better look at the large tile:

 

It could take up to 5 images in the tile, the biggest one is latest snapshot and the 2 lines description shows the camera name and when the snapshot was captured. In the top area of the tile will have up to 4 snapshot in the past updates (latest at the right) from all cameras that you had added.

 

Other features available in this release:

  • one way audio for selected cameras
  • a light weight preview for multiple cameras on main screen
  • in app snapshot (tiles)
  • digital zoom on the fly in single view
  • motion detection

Translation to Italian - Supporto H.264 e ricerca tester per Foscam

17. September 2013 21:18 by BBSYSTEM.IT in Android, IP CAM

Aggiornamento: il periodo di test è completato, adesso tutti potranno scaricare la versione 1.6 con supporto video HD dal Play Store.

La prossimi versione Android di IP CAM Controller sarà equipaggiata con motore H264, in altre parole, saremo in grado di avere video in HD se la tua telecamera supporta formato H.264.

E' attualmente in test finale e per questo vorrei invitare alcuni utilizzatori di telecamere Foscam a testare lo streaming HD nel loro smartphone Android. Se la tua telecamera è una serie foscam H.264 come 9820W, 9821W, 8608W, etc, prego clicca sul link che segue per chiedermi una beta. http://www.jerryhuang.net/contact.aspx

Per scaricare la versione beta, si prega di fornire anche il tuo account Google nel messaggio che stai per inviarmi. 

Attualmente mi sto concentrando su Foscam serie H.264, se avete altri tipi di telecamera, potete contattarmi per vedere se possibile aggiungerle, ma vi prego di notare che sarà necessario accedere alla vostra telecamera in funzione, quindi prima di contattarmi, consiglio di puntarla verso un muro o mettere un grande libro davanti alla telecamera, se la violazione della privacy vi preoccupa.

Ecco un'anteprima della app, se la tua telecamera supporta H264, un nuovo pulsante sarà visibile vicino al pulsante dell'audio:

Translation to Italian - Grazie Germania!

17. September 2013 20:54 by BBSYSTEM.IT in IP CAM, Windows Phone

Gli Stati Uniti sono stati il principale mercato per tutti i maggiori Stores (per esempio APPLE, Google e Microsoft WP). Per questo ovviamente gli Stati Uniti sono in testa come numero di download della mia applicazione (è ancora così); lo stesso vale per la versione su Android. Recentemente è stato superato dalla Germania! Che sorpresa!

Il numero di downloads dalla Germania ha cominciato a salire vertiginosamente dal momento della nuova versione tradotta in Tedesco. Insieme alla crescita di download è arrivata anche una crescita di impressioni positive. Vi sono veramente riconoscente! Vorrei poter scrivere questo intervento in tedesco ma non ne sono capace. In ogni caso, per tutti gli utenti dalla Germania, vi prego di accettare la mia gratitudine, GRAZIE!!   E, uno speciale ringraziamento va a Pascal Künzli volontario traduttore. E’ stato un piacere lavorare con lui.

 

 

Un'altra grande novità è su Windows Phone :)

Dal 1 ° settembre, IP CAM controller per WP8 è stato selezionato per essere evidenziato in Brasile, Spagna e Italia

Vediamo uno dei messaggi di posta elettronica 

 

 

E se sarà per  2 giorni evidenziato sullo Store Italiano i giorni Settembre 03-04, il merito va ad Andrea Busato da BBSystem.it, che è il nostro traduttore italiano sia per Android che per WP

Android: Motion Detect and Baby Monitor

16. September 2013 13:55 by Jerry in IP CAM

Similar to Windows Phone version, today we released motion detection feature for Android. With this feature you are able to monitor a sleeping baby while working on something else at the same time. 

 

When the current movement state reach the threshold for certain level, the phone will be vibrating and playing ringtone to attract your attention.

In addition, if your camera's audio is supported, a new "Run in background" (only for users already paid for audio) menu is available at the following place:

When this activated, the app will be pushed to background while it's still running. It's like a traditional baby monitor if you turn on the audio beforehand. This could be working together with motion detection - the app will trigger alarm when motion is detected. If however, motion detect is off in background, the video streaming will be stopped to save data usage and so battery. But once bring the app back to foreground, video will start again.

Although saving energy is being considered, running in background will still drain your battery pretty fast, so it's highly recommend to plug in charge before using this feature.

 

Italian translation:

Simile alla versione  per Windows Phone, oggi abbiamo rilasciato la funzione di motion detection anche per Android. Con questa funzione potrete monitorare per esempio un bambino che dorme mentre lavorerete o farete altre cose.

Quando il movimento in corso raggiunge una certo livello di soglia, il telefono vibrerà e riprodurrà un suono al fine di attirare la tua attenzione

 

In aggiunta, se il tuo modello di telecamera supporta l’audio, la nuova funzione "Funziona in background" (solo per utenti che abbiano già pagato per la versione con audio)  sarà disponibile in questa posizione:

Quando attivata, l’applicazione sarà spostata in background mentre continuerà a lavorare. Funzionerà come un babymonitor se avrai predentemente attivato l’audio. Questo potrà lavorare in contemporanea con il motion detect - l'app farà scattare l'allarme quando verrà rilevato un movimento. Se, tuttavia, il motion detection sarà spento in background, gli streaming video saranno fermati per salvare utilizzo dei dati e quindi della batteria. Ma una volta portata l'applicazione  in primo piano, il video riprenderà. Anche se il risparmio energetico è stato considerato, in esecuzione in background continua a consumare la batteria piuttosto velocemente, quindi è altamente consigliabile collegare il telefono al caricatore prima di utilizzare questa funzione.
