    Perdonad si estáis hablando en otro mensaje de esta cámara, he buscado pero no he encontrado referencias a ella. La he visto en:

    http://www.maximus-racing.com/fr/maxicopters/camera_hd.html

    En resumen, dicen que emite en 1280x1024, con una potencia de 50mW sólo, pero dicen que se puede llegar a 5Km de alcance...

    Lleva incluida una batería de litio de 1200mAh, y con ella pesa 125 o 150gramos (depende del modelo).

    Incluyen la cámara, y un "MMC-1105-CENTER", y necesitas un portatil: la señal va de la cámara al Center, y de ahí al portatil de forma inalámbrica... Por eso dicen que pongas el Center en un sitio alto y el portatil donde quieras, ya que no hay cable hasta el Center...

    Lo que no se es el precio, porque así por características me parece una maravilla, lo malo es que valga una burrada... ¿Qué os parece? ¿Alguien por ahí la ha visto en funcionamiento? ¿Precio?

    Gracias!!!

    MMC-1105 HDTV Wireless Camera








    MMC-1105 maybe is an unprecedented brand new concept of digital wireless camera, which is digital totally from lens to RF output circuit. For real time wireless monitor use, its resolution can be HDTV 1280×1024; its definition is 3-10 times as the former microwaves wireless camera(CCD wireless camera, the maximum theoretic resolution is 720*576 or 760*480) and COFDM. If use it for low altitude aerial photography, 60-degree you can see clearly the brand name of the cigarette box on the ground don't need change the lens focus. For book photographing or evidence taking, at one time it can photograph clearly all the words on 2-3 A4-sized papers. The above-mentioned performance of MMC-1105 is beyond the normal PAL/NTSC videography equipment can do, including some of the equipments for broadcast use.​

    Taking advantage of the most update 2.4GHz BroadWide™ RF blind-area compensable technology, the advanced technology MM-1105 takes has very good performance in signal transmission. Take basic specification of MMC-1105 as an example, the transmission power of it is only 17dBm(50mW), but its reference transmission distance can be more than 5KM.

    A complete set of MMC-1105 system consists of a wireless camera host machine, MMC-1105-Center and a laptop computer (the laptop is prepared by yourself, the video memory of which must be more than 256M). The process of data transmission is: from host machine wirelessly transmit to MMC-1105-Center, and then wirelessly transmit to the laptop. From the above, we can see the three parts can be separated in different places. And the user doesn't need to stay with MMC-1105-Center; it can be independently put in high place.

    Olfaction-Detection. MMC-1105 can intelligently find out most of the public wireless networks around it. Such as WIFI hotspot and China-Net, don't need the username and password Through setting the parameters to match with the public wireless network, MMC-1105 can wireless transmit pictures through the stated wireless network. The process of data transmission is: from Camera wirelessly transmit to hotspot , and then wirelessly transmit to your laptop (Note: The signal receiving sensitivity of the external wireless LAN card is above 5~ 10 times as the built-in wireless LAN card.).
    In this mode, the MMC-1105 Center will be temporarily abandoned.​

    The working environment between ground and air is very different. Though MMC-1105 takes advantage of the most update 2.4GHz BroadWide™ RF blind-area compensable technology, when there are barriers, its signals still will be declined to some extent. The key to control the decline within the acceptable range is to select a proper position to install MMC-1105 center (mainly for its antenna), which determines the result of the system in ground environment.

    About Weight: 125/155g including built-in 1200maH lithium battery, which can support MMC-1105 to work continuously more than 3 hours. or 1 hour for MMC-1105S


    MMC-1105 has great value in military & civil use. The main advantage of MMC-1105 is that, it can attain super high resolution of video image, which is 3-10 times more than previous micro wireless cameras. MMC-1105 can allow the user to see the very details in the picture screen.

    Such as if used for police for real-time monitoring, the high definition picture of real-time video and later-recall video will greatly help the police to attain importance evidences and to solve the cases successfully.

    The resolution of the general airborne video camera on the mini TUAV is very low. It only can allow the user to see the big objects or the objects in obvious positions, which will lose many valuable targets especially those fleeting targets. Therefore, to get better results, the users have to make the TUAV to fly back and forth many times to photograph the targets from different angles and in different times. For those unclear and unknown targets, the TUAV has to approach it close or reset the zoom lens to get better result. During war, it is difficult to get overall information of the enemy.

    Pufff

    Pufff, acabo de ver el precio en RCGroups, el sistema entero sale por 1200 euros :icon_eek: nada menos... bueno, ya irán bajando estás cosillas...

    Aquí hablan de ella en RC Groups:

    (el tipo que la presenta es un poco spammer, ha puesto varios mensajes repetidos hablando sobre la cámara...)

    http://www.rcgroups.com/forums/showthread.php?t=1170374

    Aquí podéis ver algún resultado (son imágenes del fabricante):

    (por si os sirve de idea: en el fondo es una webcam inalámbrica más un repetidor tipo router potentillo y una tarjeta inalámbrica en el ordenador potente... a ver si alguno se anima y nos decís con componentes de "PCCity" algo parecido, yo siempre he pensado que tenía que haber alguna cosa de los PC que valiese para esto del FPV... ¿54Mbps es un buen caudal de datos para meter un vídeo y audio? ¿o es poco?

    ¿Y 108Mbps? (con los nuevos sistemas que han bajado mucho de precio, como los MIMO:

    http://www.ciao.es/D_Link_Super_G_with_MIMO_Wireless_Router_DI_634M__626030 )

    Gracias y perdonad, que creo que metí la pata enseñándoos la MMC-1105, pensaba que era mejor opción...

    Edito: Creo que he encontrado un video real, a ver si es verdad y que tal está... pero con lo de los 10 frames por segundo la han matao...

    Bah, ya he visto el video (todos son el mismo, una demo con mucha niebla...) y realmente va totalmente a saltos (10 frames por segundo), no merece nada la pena creo yo...
