Crime can be very scary. But if there are security cameras, in business areas, restaurants, playgrounds, schools, parks and most areas where there are more people and less people that goes to, etc. Added cctv's can alert or prevent many crimes or even can solve crimes. Now the future are more on smart products, I was thinking also of digital signs that flashing instead of just a stationary signs, example in business areas, like restaurants, movie theatre, activity places etc, where people can be so attracted to the lights, and the night is very attractive to tourist when there are more digital lights and more colourful lights. Just like in other countries like Japan and Hong Kong, Tourist spent there evenings outdoors because of attraction to what they can see. Investors can open businesses and it will create more jobs to calgarian.
