The test for WIFI Borescope Endoscope camera ( wifi wireless snake camera)




Home Endoscope,Wireless WIFI Borescope,Tube Extendible Snake Scope Inspection Camera support iPad/iPhone monitoring



I had tested the WIFI Borescope endoscope camera (wifi snake camera).

I will compare with  WIFI Borescope endoscope and FEBON230  small wifi AP.



The product is divided two parts.

1. camera side is CVBS output.

2. compression module is  Multimedia main module + interface board with USB wifi dongle

-------------------------------------------------------------

1. camera side is CVBS output

   How can we know it is CVBS output?

   1.1All of Borescope endoscope on website is 640X480 resolution.

        I CAN NOT see the 1280X720  

   1.2  It use the " video decoder TW9900 "

       It means the camera is CVBS output.




   1.3   So, It will face the issue  problem of  " CVBS transfer  Digital" as below


       Comb filter:
 
         TW9910 is a cheap video decoder, it can not YC separate!

          This color means Moiré

 
    The below image is from wifi borescope camera.


     

   If  add the 3D comb filter , the video will as below
     ( This is my product, FEBON 100 UVC grabber card+ FEOBON230 UVC wifi AP)



      De-interlace

       it is not  3D de-interlace! It just smooth it!

 

          If  add the 3D de-interlace , the video will as below
     ( This is my product, FEBON 100 UVC grabber card+ FEOBON230 UVC wifi AP)




    2. compression module is  Multimedia main module + interface board with USB wifi dongle


This solution divide three parts

2.1  Multimedia main board.
2.2  interface board
2.3 wifi usb dongle with antenna




2.1 Multimedia Main Board.


   many many pin account!!!

   The size is very large~~~   38mm x 38mm

 


Let compare with  FEBON230  UVC WIFI small AP card. 

The size is only  25mm x 35mm 





 2.2  interface board & 2.3 wifi usb dongle with antenna

   The purpose of the interface board will provide the power to main board and transfer the CVBS video  signal to interlace ITU.656

  This solution is hard to change to the mega pixel  resolution.

  This is NOT technical  issue...  The F/W  support is very very heavy...

  For example, which sensor  can use, which resolution can use , which color parameter can use

  The condition  is too much~~




FEBON 230 is PIFA ANTENNA. The PIFA is very very cheap and performance is  also good


 No extra  wifi usb dongle! 

The size is very small!!!  25mm x35 mm





Comparison Table



FEBON230 WIFI small AP WIFI Borescope Endoscope
Main board 1. SIZE: 25mm x 35mm
2. embedded the PIFA


1. size: 38mm x 38mm
2. need the extra USB WIFI dongle


Interface board Provide the Power Provide the power and transfer the CVBS video  signal to interlace ITU.656
CVBS camera 1. USE UVC USB Grabber card solution
2. Have 3D De-interlace /3D comb filter



1. ITU656 directly connect to main chip.
2. No 3D comb filter

MEGA PIXEL If camera module follow standard UVC driver, the connect between camera and FEBON230 wifi AP  is very easy.




Due to the firmware issue, It is hard to design

There is No mega pixel wifi Borescope endoscope
