Tech notes

Gear was sourced and tested in Bombay in the week prior to the residency. (Everything was bought around Lamington Road)

cameras and quad:­­­­­­­

Surveillance cameras start at around Rs. 350/- I opted for the ccd ones (supposedly Taiwanese-meaning NOT Chinese -a phrase commonly heard in the market when referring to goods more expensive, reliable or durable) rather than the Rs. 500/- cmos Chinese ones. (There’s simply is NO guarantee for them and they are prone to blowing with the minimum of power fluctuation)  I did buy 2 during a recce, from Manish Market. The image quality was great I kept them as backup.

Jay Mit Systems. (No shop front, No solicitors.) 
They consult and design entire security systems for the Gujrati / Jain jeweler community and do not sell to individual shoppers. I was led to their 2nd floor shop in Tinwala building, Tribhuvan lane with reference from a shop in Kilin lane that sells modulators. After a long chat with the owner, he agreed to sell me his stuff.

The 4 Pcbs’s, lens, and casings were assembled and power and RCA (female) jacks soldered on. (+ DC 12 power adaptor.) The quad processor was also purchased at JayMit. (Rs. 4000/-). 6” x 4” x 1” box with 5 bnc-in and 2 bnc-out.  Apart from the important mirror function (necessary for this project) the owner told me that the processor could motion track demarcated areas on the 4 quads and also activate vcr to record. (in case a rat entered the jeweler shop at night, this movt, (frame diff) will trigger vcr to record the moment) Chirag, a young and very co-operative guy who works at JayMit, also sold me 4 versatile camera mounts (Rs. 150/- each)

RF modulator and coax:

ComsFIbre / Romi Cables
also in Tribhuvan lane proved to be Godsend. I was able to source a really good RF-modulator (much better than we technically needed). The good Sardar suggested channel 3 as opposed to channel 2 to be sure that free-to-air channels (dd etc), frequencies would not clash.

Gurpreet also provided me with 8 bundles of 91 mts rg-6 coax cables (jelly filled). I could pay when I returned or give back to him by paying 25% of the cost.  (91 mts bundle= rs 750/- x4)

RF splitter (4-way) Rs 90/- F connectors (Rs 2 each) BNC, RF, RCA connectors (Rs 10 each).

audio mixer, mics, xlr cables:

Electronic Emporium (near Dreamland Cinema).
Tried Stranger mixer (2000 rs/-) Phono in. It didn’t have line out (just mic out) and would need an amp. Settled for Yamaha (4 XLR mic + line out),  Rs 6000/- + tax. Looked at Ahuja condenser mics (lapel) but signal dropped after 30 mts because it was phono (imbalanced). Settled for Shure dynamic cardioid’s (Rs 850/-). With XLR (balanced.) cables.  (Rs. 15 per metre)

Noronha supported all trials and testing and made the 100 mt. cables with XLR male female connectors asap. When I picked them up from his place in SantaCruz the night before my departure, I was delighted that they were in 4 colours, orange, green, blue, yellow
