NEW DELHI: Demand for Chinese closed circuit television (CCTV) and surveillance cameras are increasing in metro cities due to the recent brutal gang-rape incident in the national capital, Assocham today said.The chamber said manufacturing of CCTV cameras are very low in the country and thus traders are importing from countries like China, Taiwan, Malaysia, Israel, the US and Europe."In terms of sales, Chinese CCTV cameras are selling like hot cakes," it said in a statement.Out of the 200 traders, who participated in the Assocham survey, majority said their sales have increased by over 60-70 per cent during the last one month.Further, it said lack of government support, absence of regulatory framework, large investments and outdated technology are key reasons holding back domestic electronic companies from venturing into the CCTV domain leading to increased dependence on imported products."The need for safety and security in almost every walk of life has fuelled the demand for CCTV cameras and more so after the Munirka gang-rape incident," Assocham Secretary General D S Rawat said.The video surveillance and CCTV market in India is growing at a compounded annual growth rate of about 30 per cent is likely to cross Rs 2,200 crore by 2015."Indian CCTV camera market is currently poised at about Rs 1,300 crore," it said.
