There are also disadvantages to the usage of wireless security cameras. For example, digital video recorders can sometimes pick up the signals from these cameras, threatening the security of the images. Also, if one knows the proper frequency, the signals can be jammed.
You know the myriad of activities that go on in a large metropolis. People go to offices to take care of business, shop owners try to sell their wares, students go to attend classes, and drivers maneuver the cars and trucks around-such a lively bunch of activities. Unfortunately, a less-than-pleasant activity also strives in the city-crime.
However, in most cities, the officers of the law are usually outnumbered. To make up for the disadvantage, they resort to surveillance cameras to monitor public areas. Surveillance cameras alert operators to areas where violations of the law occur, allowing them to dispatch police officers more quickly.
