<div>Walu, I'd like to add a comment.</div>

<div>Below would be a very basic overview of a metro cctv system. As it becomes clear, the task is not cheap nor simple:</div>
<div> </div>
<div>- Webcams and wifi/simple data platforms can only provide very limited functions as they have serious limitations on picture size, quality and control.</div>
<div>- As a minimum, IP cameras can be used with high quality lens assemblies. These provide Wide angle, Pan,Tilt and Zoom features that can be remotely accessed by the operator. ( Added costs )</div>
<div>- IP cameras or even regular cameras with analogue to digital conversion streams consume a lot of local loop capacity between them and an operator room. With the fiber optic growth in major cities, this may no longer a problem</div>
<div>- All cameras require some sort of low light boosters in areas where there are low light conditions eg, infrared etc. ( Added costs )</div>
<div>- As the system would be tamper proof, special power backup ( eg solar ) and protection would be necessary. ( Added Costs )</div>
<div>- The cctv operation centre etc would need an archive system to store all the data gathered for analysis etc. ( A huge cost here )</div>
<div>- Training would need to be provided to operation centre staff. </div>
<div> </div>
<div>Imagine someone hacking into a wifi camera system and able to monitor the events? This itself would be a big issue to security.</div>
<div> </div>
<div>I guess there would be need for some sort of a security policy and budgets to push for the technology implementation over a period of a few years. Hopefully policy makers will see the urgency and push forward plans to make it more safer for all. </div>

Fine, i didnt tip the security guard but it was because he wasnt in site...<br>
><br>> Anyway, just wondering, with all this 'Butterfly' cameras and now 'HOTSPOTS' hovering above the City, why cant the Police take advantage of them and beef up security? I dont think we need to wait for the year 2030 or another multi-billion donor funded project for this to happen. I suspect there is still a HUGE disconnect between regular (r-)Government and electronic (e-)Government.<br>
