Case Studies

Delhi CCTV

Government-sponsored CCTV at the Delhi College of Arts and Commerce and the Shiva Ji College – part of Delhi University in India – was to improve student safety, reduce theft, and provide 24-7 coverage.

Akshat Srivastava, CEO at the Indian-based electronic security company Alvarion Vision, said: “The government was not about to compromise on any aspects of quality for this university project. There were numerous instances of other vendors failing for this very reason. In fact, the entire process took 7 months from first demonstration to installation, but Hikvision always impressed.” Mr Srivastava decided on centralised analogue CCTV featuring six Hikvision products. Placed in the colleges’ corridors is the DS-2CC5192P low-light dome camera. Since cameras are not within classrooms, resolution clarity was required to identify students and faculty from others that should not be on the premises. The dome’s 650 TV lines provide the required high resolution.

While most of the university keeps to office hours, this dome’s Super Low Illumination feature often is not needed. However, noting the similarity in model number, Hikvision’s DS-2CC5192P-IR3 IR weather-proof dome offers extra coverage of some corridors. In this case, the DS-2CC5192P-IR3 offers up to 40m of infra-red range and 650 TV lines high resolution.

Outdoors

Two other Hikvision IR bullet cameras: the DS-2CC192P-IR3 and the DS-2CC192P-IR5 cover the university’s outdoor areas. Both models are placed at the university’s main gate, college entrances and exits, and perimeter areas (including open grounds, such as playing fields and the students’ quad).

An extra challenge is the sub-continent’s climate. Mr. Srivastava said: “India’s weather can be absolutely brutal. The daytime conditions are almost diametrically opposed to the night-time conditions. In effect, these cameras go through scorching heat in the day and bitter cold in the evening. Additionally, there are the monsoon seasons that inundate India with rain and humidity.”

Both cameras’ IP66 rating is essential. While both makes have the same “general” responsibilities, there are marked differences – hence the differing IR ranges. For the DS-2CC192P-IR3, and its differing IR range of up-to a maximum of 60m, it is suitable for the college entrances and perimeters. However, for CCTV coverage requiring a longer distance, the DS-2CC192P-IR5 has 50 to 60m of IR range. In the case of this university, the main exit provides an example of this need: an area requiring extended coverage to identify, and track, people leaving the site.

Either way, both cameras’ resolution (650 TVL high resolution for the DS-2CC192P-IR3 and 420/480/540TVL for the DS-2CC192P-IR5) provide the clarity necessary for security personnel.

Hikvision’s DS-7204HVI-SN and 7208HVI-SN standalone digital recorders are connected to LAN cables and LCD screens in the security guarding office and in select university administrators’ offices. Four, eight or 16-channel synchronous playback and up-to 4CIF resolution recording let officials view the many Hikvision cameras on the two campuses.

As Mr Srivastava added: “The success of our Hikvision tools at the prestigious Delhi University has literally opened the door for new security solutions at a variety of other universities throughout India. Hikvision and Alvarion Vision’s future is very bright in India.”
