CV301 CM200 VideoCamera repair Easy for N-Scale! Or: Everyone can easy install video into it's own locomotive now! Hello. Continuing attracting people into engineering field of making jazzy usefull and developing things , let us speak about N-Scale Locomotive VideoCams. We live at 2013 Year now! There are lot of Chinese cameras everywhere! Among them there is a very small SV301 CM200 Wireless Camera. It have 8 video channels at 2.5GGz frequency region, color and sound! It has 8 mm width and height! It can be easily inserted into variety kinds of N-Scale locomotives! This Camera costs as little as 25 dollars! It's extremely cheap! BUT! This camera works short period of time, and not so dependable. Damage occurs when supply voltage is non-constant, and have short absence periods. This may happen at any N-Scale locomotive at railroad modelling layout! After detailed inspection i understood, that Chinese people havent enough knowledge in Electronic Engineering! Namely: Digital CCD sensor is connected to universal VMicro chip. This chip requires connection of Read Only Memory (ROM). This ROM chip stores CCD setup data. VMicro read it during startup. Chinese people substitute Read Only Memory onto Electrically Erased Programmable Read Only Memory (EEPROM) (first error), and forget to solder write protect pin to +U. Therefore any unstability in power supply can lead to unrecoverable damage of functionality! HOW TO TREAT CM200 from Chinese-ability: In aim to repair CM200 Video Camera do the following before usage: For NEW CAMERAS: 1) Disconnect pin7 of EPROM from GND and connect it to pin 8 (+U) Now Your cameras will work and work even at extremly unstable electrical pickup which exists at N-Scale locos. For DAMAGED CAMERAS: 1) Take good camera. 2) de-solder EEPROM. 3) Download all data into IBM-PC-AT use PonyProg and very simply COM-port programmer: (http://www.lancos.com/prog.html ). ) 4) Take EEPROMs from damaged cameras and program it with good data. 5) Solder it back 6) All cameras must continue work! As a result: We have not so Chinese cameras now at 25 dollars! It's work well now !

Hello again! Are there anybody who prefere to play as real train driver watching tracks and signals from cab videocameras of model locomotive? Are there anybody who already have locomotive model with VideoCameras? -------- Vadim
I have to admit, I have been considering the idea of installing a video camera into my old Life-Like FA-2 if I upgrade my FB-2 and get the updated FA-2. Also the idea of doing the model railroad version of 3:59 - Canada's Fastest Train has some appeal if I ever decide to correct a second Del Prado LRC. Of course, the current lack of a layout would be a demotivating factor.
Yes, VideoCameras now is still not so smal, but it's possible now to install it into thick (not with hood) locomotives. ------------- Vadim
It's correct EEPROM from CM200 CAMERA. Please rename this file to*.e2p and Flash by PonyProg choosing 24C16 type of EEPROM in settings View attachment PonyProg_24c16_EEPROM_from_CM200.doc
I use a Looxcie 2 camera that sits on a flat car and gets pushed by a loco. Its controlled by a smart phone or and Ipad. Check it out here. http://youtu.be/ULJ-1YTbAvY and here http://youtu.be/80xrDDIwG5U
Good quality, but this camera does not work in real time, sending video from cabin of shunting loco to display near trottle in real time via radio-channel. My aim was a construct technical vision system for modelling realtime shunting work.
