Hi Mark.
The box says "ZTV Electron". I'm sure the guy that I bought it from was an acting distributor and bought a bunch at a cheap price and put them all on ebay. ALL of the research I've done points to Electron being the manufacturer of all the camera's talked about. It's a matter of marketing and markup on who you purchase it from. (IMHO)
If you go to
http://www.sznewway.com/ they have all the goods and probably the cheapest for a direct purchase. The little 200mW are 30 bucks direct purchase. The company is real good on returning emails. A friend of mine has purchased from them with no regrets. I was about to buy the 1500mW from them but I saw one come up on ebay. The 1500mW is good if you are like me and technically illiterate in the video area. It WILL put out the signal, and YOU WILL recieve it, no matter what.
Hope this helps
Spanky
