Futian is the centre of the universe

So I am consolidating my various databases, getting ready to migrate from Bento to Filemaker Pro 9 Advanced here at the home office. My list of cctv/dvr manufacturers has expanded like a football team at the Home Town Buffet. One curious fact has emerged: the Futian District in Shenzhen, Guangdong, China (PRC) is the centre of the CCTV/DVR universe.

Companies like Shenzhen's Vangold Technologies offers over 50 different DVR cards to DVR manufacturers. Aopvision Tech's offering of just 16 cards, seems small by comparison. With all of the small companies that dot the countryside, you'll never look at a "generic stand-alone" DVR the same way again. The case is made somewhere, the DVR board - somewhere else, the DVR software - somewhere else again ... The combinations are complex enough to make you cry.

All totaled, my database has passed 300 manufacturers - from the biggies like Pelco, Bosch, GE, and Honeywell, to the mid-sized like Dedicated Micros and GeoVision, to the seemingly small companies like Shenzhen's New Surway Digital Technology (with their 40 DVR cards). So, do the math ... over 300 DVR manufacturers x an average of two dozen products each = way more than 7200 unique DVR products on the market. Ouch! How does one keep up?

And there sits little Futian District - the epicenter of the DVR universe?
