The use of surveillance cameras in public places is a controversial topic. Some people argue that cameras are an invasion of privacy and that they do not deter crime. Others argue that cameras are a necessary tool in the fight against crime and terrorism.
There is no clear answer to the question of whether or not surveillance cameras are effective. However, there is some evidence to suggest that they can be helpful in deterring crime. For example, a study by the University of Nevada found that crime rates fell by 18% after surveillance cameras were installed in a public housing complex (1).
Another study, this one by the University of Cincinnati, found that video surveillance caused a reduction in violent crimes, including homicides, rapes, and robberies (2). There is also evidence to suggest that surveillance cameras can help solve crimes. A study by the University of South Wales found that CCTV footage was used to identify offenders in 82% of burglaries and 83% of robberies (3).
Overall, there is no definitive answer to the question of whether or not surveillance cameras are effective. However, there is some evidence to suggest that they can be helpful in deterring and solving crimes.

The primary disadvantage of a home alarm system may be its expense. It is costly to have the system installed in the first place, but security companies charge a daily or monthly fee to provide monitoring services as well. These fees can quickly add up, so if you are on a budget, it may put a strain on your finances. 
Disruption of signals Â This is the major con. Wireless IP cameras operate on one specific frequency. The chances of the signals getting disrupted are high if there are other networks like internet or microwaves. Risk of hacking Â If the camera is not secured properly, there might be the risk of hacking. 
There’s no one-size-fits-all answer to this question, but here’s the gist: Wired security systems have more reliable signals, whereas wireless systems provide a more streamlined installation and can be used in places where wired systems can’t. 
The jury is still out on whether or not surveillance cameras are effective. Some say that they are a necessary evil, while others believe that they are an invasion of privacy. Whatever your opinion, it is undeniable that surveillance cameras have become a part of our everyday lives.
