Wireless Camera transfer to Pocket PC

hi
I spent allot of time searching the net for a wireless camera (for security purposes) that has the ability to transfer live video to my Qtek2020i which is wireless enabled.
I am not looking for an IP cam, I dont want to view the video by connecting to GPRS, I want my pocket pc to find the camera as a wireless access point and using some software I want to see the video from that camera, is there anything like that?
all of the wireless cameras I found has a reciever device to connect to TV or VCR and this is not what I want, and the others has the capability to send the video to internet and by accessing the site from the PDA you can see the video, this is also unwanted for me.
so please tell me if there is such a cam and how to buy it and how much, I really need such a product for controlling my office while I am moving in the building, my job includes moving allot to different offices, so I need to check if anyone mess around in my office during my absence directly. i dont want to record then watch, I need something live !
thanks

[Q] Webcam app? (EVO as desktop webcam)

I'm wondering if anyone is using their EVO as a webcam with their PC, preferably using the front facing cam. I've tried a few options I found while searching but haven't had success.
WO Webcam looked promising, especially since it uses bluetooth, but I get the error "cannot load orange bluetooth camera device" when trying to connect my EVO to the desktop software. This might be due to me running Win7 64-bit because they don't currently offer 64-bit drivers.
USB Webcam is on my 'to do' list but I read a comment saying it doesn't use the front facing cam.
Fring appears to be strictly for the phone and doesn't act as a desktop cam.
Are there any other apps that might work? Only using the rear cam isn't necessarily a deal breaker but it isn't the best option when between the EVO's kickstand and my dock since the rear cam faces down and will require repositioning. On the plus side the rear cam is of better quality.
Oh, and yes I searched but the thread results didn't answer all my questions, plus new apps may have been developed since June.

I use IP Webcam (http://ip-webcam.appspot.com/). It allows you to turn your phone into a webcam server, but it also can be used as a remote webcam for your PC. I've used it here and there are a remote PC webcam and it works pretty well.

Might want to check out "DroidCam"

[Q] ???Remote Screen/Display Solution???

Hey Guys,
I need your help. I currently have a carputer running Windows XP in my car now with an 8" touchscreen interface. It works and does what I want it to but I'm thinking I want a cleaner solution. At first, I was thinking about loading Android onto it but then I was thinking I could probably go one step further. My EVO does everything I currently have in the car (nav, music, video, etc) and it'd be awesome to use my EVO as the CPU if I could get it working with a bigger screen. Is there some kind of device on the market that acts as a remote display/screen that allows seamless touchscreen functionality? I'm talking about mirroring the display of the EVO. Like via bluetooth or HDMI out with USB interface for the touchscreen function?? That would work so much better because all I would have to do is mount the screen and run power to it. I could completely remove all of the computer hardware saving space and points of failure. It'd be best via bluetooth that way I wouldn't even have to take it out of my pocket. If there was a way to get it to work with the HDMI port for the video/audio feed and the micro-USB port for the touchscreen interface, I could just run a dock in the car and work it that way. If anybody knows of a device or a solution that would accomplish this, PLEASE let me know! If you think you have an easier/better idea, please feel free to share that as well! Thanks!
-Greg

I know there are several developers on the brink of completely unlocking the HMDI port functionality so I know it can be accomplished...but getting the touchscreen to be seamless I think would be the most challenging part...

Ok, so after changing some search terms, I was able to find something similar: Mimo USB Monitor. The entire monitor (power, video feed, and touchscreen interface) is though one USB connection. I came across this XDA thread that pretty much explains how it could possibly work: http://forum.xda-developers.com/showthread.php?t=898418 Has anybody done any research on this or know anybody that has or is currently working on something like this??

Any ideas??

That wont work. The usb port does NOT do video out. Your only option for video out is the hdmi port, which as of right now, will only output video and pictures. As said above, there are dev's working on full hdmi output, but who knows when it will be available.

That monitor is a standard USB DisplayLink device. No special video out needs to be on the port, you just need a device capable of operating as a USB host with the correct drivers loaded (which are open source on normal Linux and thus should be portable to Android if someone was so inclined). Thus, any phone which could be used with a USB keyboard, mouse, thumbdrive, etc. can support that monitor.
That said, I've looked a few times and do not believe the Evo has USB-OTG support and it certainly does not have a standard host port, so we may be SOL there. N1 users can do it for sure, I'm pretty sure I've seen it used with an Ubuntu install, creating a kind of hacker's version of the Altrix around a year earlier.

Alternatively, it's not the fasted method, but there are a couple of software solutions that basically let you VNC to your EVO from the PC. androidscreencast is one (google that phrase, can't post links yet) but it seems as though it's stalled out. I think that Droid Commander (or something like that) also has a screen casting option. This way you don't have to worry about touch screen drivers etc.

I wonder how a cheap chinese tablet with a usb host would work.
I've considered just installed a cheapo tablet in my car then go out to rca's or a bluetooth transmitter. My line of thought on is most headunits/music is only stereo(2 channel), so you wouldn't lose anything there. The two big problems I forsee would be a reduction in the the output quality using 3.5 to rca and finding one with a fm radio thats worth a damn.

Well if you really wanted to go a tablet route. there is the smartq v5 you can pickup for around 250. it has full hdmi out usb host bluetooth and hardware video decoding (1080i hdmi video looks soo nice on a tv form it). You can download the android 2.2 firmware and run rocketplayer for allmost any video.

Just ordered Miracast + AirPlay dongle

UPDATED WITH REVIEW:
In-depth review below, will update in a few days to cover DLNA support and revisit Miracast experience while at home (currently discussing the experience at a university)
The PTV Miracast adapter works as advertised, but isn’t perfect. Miracast functionality works like a charm, but with the same slight delay in most other adapters out there. AirPlay is listed as a feature, but don’t expect it to work. Upon opening the package, I was greeted with a matte black, rubbery dongle that was slightly larger than a USB thumb-drive. Under the cap is the HDMI plug, on the other end are two micro USB ports -- one for power and one to connect a storage drive. On one side of the USB end is a tiny button that doesn’t clearly indicate it’s purpose, but is meant to switch between Miracast connectivity and AirFun mode (see below).
Using this adapter isn’t as intuitive as I would like it to be, but it does work. When you initially plug the device into the HDMI port of the TV and USB power, you’re greeted with the AirFun screen, which is green and black. This screen displays the dongle’s IP address, a url containing the IP address and ending with “/remote,” and what network it’s connecting to. When no network is available, it turns itself into it’s own wireless network to allow you to connect. Visiting http://ipaddress/remote takes you to a web-based remote for the dongle to set it up and control the DLNA features of the device. When connecting to this address from an Android device, it prompts you to download the app for this same control. The app is called AirFun and CORRECTION: is in the Play Store - https://play.google.com/store/apps/details?id=com.realtek.airfun.client. The app appears to be stored on the dongle itself also. Don't worry much about this app after you've adjusted the settings to your liking. Use another DLNA app for your media, MirrorOP if you wish to take advantage of that, and wait on AirPlay.
Connecting the dongle to wifi is easy, but the first step isn’t apparent. You must first connect your phone or tablet to the wifi hotspot the dongle creates. At this time, you will not have an internet connection and will only be able to connect to the Miracast dongle. The next step is to go to the url containing the ip address that is displayed on your TV or use the app to connect to the device. In the settings, you can choose the wireless network you want to use and enter the password. Once this is completed, the Miracast adapter will disconnect it’s own hotspot, disconnect your phone or tablet from the device, and connect to the wireless network you chose. At this point, you should connect to the same wireless network in order to pair with the device again.
I must share a mistake I had made in hopes of those reading this can learn from it. Do not, under any circumstances, connect to an open wireless network in which you need to visit a web browser to sign in or click and accept button. The Miracast adapter can’t choose to accept a license or enter login information. I did this at the university I work for and found that I could no longer access the dongle for anything relying on wifi, including accessing the settings. I had attempted to disconnect and reconnect, reset, unplug and plug in again the device. As I had already set it to connect to the wifi that requires authentication in a browser, it automatically connected to it every time. I was forced to bring this in a location in which that wireless network was unaccessible so that I could connect directly to the device’s own hotspot and connect it to another network.
Once the wireless connection has been connected to both the PTV dongle and your phone or tablet, you can begin using MirrorOP, DLNA, or AirPlay. Please note that Miracast is connected using different steps which I will discuss later. No wireless connection is needed for Miracast and if this is the sole purpose of using this device, you can ignore the steps above and continue to the section specifically about Miracast. After connecting to wifi, I tested MirrorOP and found that connecting to this worked without issue. The screen mirrored as any other MirrorOP connection does. MirrorOP is an AirPlay-like connection except that it requires a rooted Android device or jailbroken iOS device to connect. It mirrors the screen like AirPlay to a device on the same wireless network. The MirrorOP app needs to be installed on your device to make the connection. Though screen mirroring works, MirrorOP does not support audio mirroring -- the audio will continue to play through your phone or tablet.
Connecting to AirPlay was very disappointing. I attempted to connect to AirPlay both at the university I work at and at home using an iPad on iOS7. In each attempt to connect, the iPad recognized the Miracast dongle as an AirPlay device. When selecting to connect to it, it appeared to work initially. Choosing a photo to display on the AirPlay device, however, proved nothing worked. The photo would not project to the TV. The same applied for video as well, but I have not yet tested audio. When enabling screen mirroring in the AirPlay settings, I was also disappointed by the results. The notification bar turned blue, the device appeared to be trying to connect for mirroring, then the AirPlay settings reset, turning off the connection to the dongle. No matter how many times I tried, it wouldn’t work. It may be my lack of knowledge with iOS and how to properly connect the devices, it could be an incompatibility with iOS7, or it could just be a falsely advertised feature. I don’t know the answer to this. EDITED: If I am correct in that Visiontech makes this device, their website (in a couple of posts below) indicates AirPlay is a feature still in development and will be added in a future update.
EDITED: DLNA works as expected. I did have some buffering/stuttering, but that was likely due to my new ISP which is a reduction in speed. Any DLNA/UPNP app or device will recognize this dongle and send content to it. Since DLNA plays the content locally, I haven't narrowed down which files are supported. I have not had any issue with mp4, which should be expected. In order to use DLNA, this dongle needs to be in AirFun mode, but you don't need to use the AirFun app to use it. This app just gives basic functionality and allows you to setup the dongle.
The most important feature in which I purchased this for is the Miracast functionality. I tested this in two different environments and found two different user experiences. I tested this at the university I work for and at home (which I am still testing more at home and will update this with more information later). Before you can connect to Miracast, you must press the button on the side of the dongle twice to switch to the wireless HDMI mode. At the university, the experience was such that I don’t feel it would be beneficial for the classroom. Connecting took several attempts before it was successful. Upon a successful connection, most of the time my device’s wireless connection was disconnected and reverted to cellular data. The screen mirroring worked as it should, however with a fraction of a second in latency. Audio transmitted to the TV flawlessly as well. At times, especially during heavy activity, the TV would fall further behind than initial connection and the picture would display large groups of poorly rendered blocks. This was further exaggerated when I reconnected to wifi for some reason. It may be due to the large number of wireless devices on a college campus causing interference that caused these issues, but I don’t know enough about networking to make an educated guess to this. I did notice turning the HTC One’s Power Saver mode off improved the experience, but only slightly.
EDITED: At home, I get mixed results. Most of the time, it works flawlessly via Miracast. There are times that the picture lags behind and when it starts to, it can be tens of seconds behind. It eventually catches up, especially if you stop your activity to allow it to catch up. With that said, I streamed a few movies from Plex to my HTC One which was Miracasting to the PTV dongle. I did not see any moments in any attempt in which the mirroring had fallen out of sync with my phone. I did, however, find a few movies that would not play sound over Miracast. I am not sure if this is due to bandwidth, licensing/authentication/DRM, or something else entirely. I need to investigate the files more in depth to determine if it's the stream. I tried to play a game with this, but I honestly found myself looking at my phone more than the TV to see where I was touching on screen. I didn't notice any delay here either, but I wasn't playing a complex game either. I ought to try this using a game controller and see how it performs this way. I also discovered that Google Play Music and Google Play Movies & TV are blocked over Miracast. They will not play, even locally stored music tracks. Play Movies tells me this feature is not supported, while Play Music will either display "Cannot play track" or disconnect the Miracast connection completely. Upon contacting Google with regard to this, they responded indicating that this is normal behavior and suggested I buy a Chromecast. I shouldn't have to buy another product to use Google services that already work on my device.
Being a Sprint customer and experiencing network issues regularly on their cellular data, I have installed an app that floats network download and upload speeds on my screen so that I can determine if anything isn’t working due to my internet connection. I noticed that while connected through Miracast, my upload speeds were incredibly high. This is what I would expect from a Miracast connection considering 1080p video encoded as h.264 mp4 video and up to 5.1 surround sound audio is being sent from my phone to the dongle over wifi direct. For anyone curious about the network activity, my upload speeds floated between 7-9 Mbps while connected to Miracast. Download speeds remained normal for the activity I was performing.
I also wanted to note that the PTV Miracast adapter gets about as hot as the HTC One can during high activity. It can be uncomfortable to touch. The included manual warns about this and promises that it will not affect performance. I am still concerned of the heat, despite the manual’s acknowledgement of this issue. Hopefully the heat doesn’t affect this device’s lifespan. I hope that this in-depth review has been helpful to all those who have read it. I would recommend this product to others, but I would warn others of the shortcomings this dongle has as well. The $50 I paid for this was a fair price considering the average price for Miracast today. Others at the same or higher price don’t offer MirrorOP or AirPlay -- I’m hoping a firmware update down the road fixes the AirPlay problems.
Tested with:
MirrorOP - Nexus 7 (2012) on Android 4.3
AirPlay - iPad 2 (two different iPads) running iOS7
Miracast - HTC One on Android 4.3 Sense 5
Full HD 1080P WiFi Display Dongle HDMI Wireless PTV Support DLNA / Miracast
http://www.amazon.com/gp/product/B00ESUPKE4/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

I just received this dongle. Haven't had time to play with it yet, but will very very soon. I did manage to test whether or not the HTC One would connect and on 4.3 Sense 5, it connects and detects it. It's not as intuitive as I would hope, but I'll elaborate later. iPad connectivity via AirPlay will be tested soon too.

Well, I plan on writing an in depth review later and putting I on the Amazon page too. But some initial thoughts:
So far, miracast works great! WiFi turns off while connecting. Not sure if this is normal or not. Performance is also worse with wifi on, in fact it can be very unusable with wifi on. But this was tested at work so far, home wifi might be a different experience.
If you plan to use any of the other features, I don't recommend setting it up on a wifi that needs to be authenticated - as in if you need to open a website, get a splash screen, and either sign in or accept a license agreement. This is not possible to do on this device and it locked me out of the dongle because it was connected to this kind of network and I had no way to change it.
You download the app to control this device directly from the dongle via ip address. You use the app for everything besides miracast - Dlna, configuration, etc.
I'll update op with full, in depth review after I spend some time with it.

EDIT: testing at home not disconnect of wifi upon connection. iPad on iOS 7 will see the dongle as an airplay device, but can't connect to it for mirroring, not sure what else to do with it. More testing to come.

Another note for everyone before I write my in-depth review... Airplay doesn't work. The iPad will see the dongle as an Airplay device, but won't connect to it. Tried screen mirroring and just picture sharing, neither worked. Could be something to do with iOS 7 or something.

Updated OP with in-depth review. Need to revisit two sections after I play with it some more. Will update in a few days.

Not having much success at home either. It works for a little bit, then has problems like I experienced at the university. Still planning to update with more info. But I think I found the company that makes this - the vendor has left this information out and the packaging doesn't include this info either. The specs, description, features, and pictures are all identical.

In case anyone wants to investigate further.

Wow! this review is very helpful man. thanks for this review. Now I think I want one :cyclops:

No problem. Shop around though, I think if it supported 5ghz wifi like miracast is supposed to, this would have been a better experience. I just recently discovered that.

HI,
2 weeks ago I got this unit http://www.win-star.com/eshop/goods.php?id=159
I choice it because of the integrated LAN, and simplified functionality (no android, no need to play with air mouse).
It prove to need it own mouse to switch between different modes, as there no any button on unit itself(only hidden reset)
During first star the Unit create own wifi network so I connect to it my samsung galaxy s4 active. However I was unable to test miracast mode not connect.
Then I switch to "bridge to wireless" trying to connect WS-AV601D1 to my existing network but unsuccessfully. I switch back manually to "AP only" mode, however since then I can not see any more networks from the device itself nor to access WIFI settings(its gray/unaccessible). I can not see anymore the open WiFi network that the device should make. I reset it several times to default settings but it going to "Bridge to WiFi" mode instead of "AP only". WiFi light not switching on at all, and wifi module is unaccessible. WiFi module fail about 10 min after first start.
Note that the unit support only WEP encryption, and have no settings for connection to not broadcasted /hidden SSID. So practically I could not connect it WiFi to my existing network even if it works(unless broadcast SSID and change to WEP)!!!
Further I could test only airplay(android airfun appk) from my s4 active and notebook, and screen mirroring from my notebook only(having the device connected to my network via LAN cable). Using the software provided.
Most important for me was the 1080p video played from notebook to TV quality. So the quality was bad, looks like xvid 700MB rip(or more like x264, baseline, ultra fast, 1000bit/s encoding). Dont understand me wrong quality was fair for animation movies of my son, despite of HDMI playback of same video you can not see each hear and dimple of actors face). There was some sound distortion too, however i dint paly with sound settings of the unit. Upload speed during playback was 2-3mbit, while normal speed within my network is 6-7mbit. Note that the Unit is LAN connected to my Asus RT-N66U.
I already send my back to China and waiting for refund.
So I could not test miracast! Does it provide better video quality when mirroring 1080p video What unit you could recommend

I purchased the iview Mira Cast dongle and it pretty much works the same. I did notice a slight lag in playing videos and sometimes it falls behind. The dlna feature works really well but with no remote you have to push everything from the One or browsing your dlna server with another app. I use skifta.

Installing a tablet as a backup camera monitor in my car

So I've had this fantasy of installing a tablet in my car's dashboar to act as a car computer. That means I will be able to access my google music cloud, using it as a radio, navigation system, OBD scanner, etc... (I plan on getting a tablet with cellular connectivity).
But the thing that looks most complicated to me is to hook it up with a reverse backup camera and to make the camera feed pop up every time i put the car in reverse, and close when I put it out of the reverse gear.
Does anyone have an idea of how I could make this happen?

You'd have to, not only, find a way to interpret the reverse signaling via USB or through the OBDII connection, but also accept the video input from the backup cam. Considering most aftermarket backup cams use a standard RCA connection for video and reverse light for a trigger, I'd say you're better off either getting a headunit that supports a backup cam input or a rear view mirror with a ghost screen.

Yea I've seen some people on youtube managing with it. Some used RCA to USB OTG adapter.
Some examples:
This guy used this this which connects to the reverse lights' power.
This guy did it with a webcam so there would be no need of using RCA adapter. The only question is how do you make the video feed pop up automatically when going into reverse gear.

You'd have to find something that understood the reverse signaling or interface with the OBDII on the tablet, other than that I have no idea.

Actually, if you just wired the camera to use the 12v+ from the reverse lights, then the camera would only be on when the car was in reverse. Then it's simply a matter of having the system display an image when one is being transmitted, and turn off the app when video transmission stops. Seems this would be much easier than trying to tap in to OBDII and look for an R signal.

Yea I managed to get to that idea already. But, I will probably abandon this project since in my annoying, full of bureaucracy country it is illegal to mess with your car's electricity if you don't have an electornics engineering degree.

Wow. That is crazy. I had no idea that vehicle laws in Israel were so strict. Would you be allowed to install the system if it all plugged in to the cig lighter? Therefore it could be seen as a complex accessory, rather than a modification? I'm just curious.

Wifi connected reverse cam
You should check out how Garmin codes for this scenario. The BC30 connects to the reverse 12V and only transmits when in reverse. They use a wifi receiver that is integrated into the power cord. There is a setting in the OS to either auto switch to camera or only switch when told to. They use 2.4GHz

I have sourced a wifi based reversing cam , but the problem is that when it transmits my samsung galaxy note drops its internet connection and therefore google maps etc. I am a newbie, so there might be a way to hold two connections open simultaneously? Any ideas?

I think this is going to be so complicated and that the amount of time and effort put into it would far outweight the cost. you can buy very low cost backup camera addons that work in any car on ebay straight out of china. You could probably sell your tablet on a used goods site and buy one of these addons and still have money leftover form the sale of the tablet.
