Benefits of CCTV cameras cannot be ignored. Surveillance of a premise helps in deterring crime. Anything illegal or undesirable going on in the premise can be monitored. It can be recorded and viewed later. Even if the system is not working, anti-social elements won’t know this fact! They may refrain from any wrong-doing owing to the fear of being caught. Its mere presence puts off crime. However, its actual success in reducing crime has been debated. Statistics do not support this claim. Recent survey by the UK police concluded that only 3% of crime was solved because of CCTV security cameras. Many times, the surveillance instruments have been subject of attack themselves.
No technology is foolproof. CCTV security cameras are vulnerable to assaults. Individuals with mal intentions resort to damaging them to carry out any activity. The tactics employed by
them to prevent surveillance and the manner to overcome such problems can be given as below:
Destroying the Equipment
Intruders may destroy the camera to prevent their recording. Damaging the device may lead to failure to prove the crime. Owners may never be able to find out the people who committed this act! This is especially true for outdoor appliances.
Spraying Liquid over CCTV Cameras
Many times, spraying things like water over the device makes it too blurry to watch. Images obtained are not clear. It may not serve the purpose it was designed for!
To overcome the above mentioned two problems, one may select vandal proof CCTV security cameras. Try hitting this system with a baseball bat! It won’t break. Cameras bubble is made from aluminum, magnesium, brass, and zinc. It remains indifferent to even a vehicle running over it. Spraying water may not affect the system. On the other hand, spraying water continuously for some time on an ordinary appliance may blind it.
Infrared Light can blind the System
Infrared lasers, if fired to CCTV security cameras , can instantly blind the appliance. Wearing high brightness Infrared Light Emitting Diodes (LED) may restrict the system from identifying the individual. It will know where you are but won’t be able to recognize you!
Color filters can reduce this effect. Many tools come with such filters and they can be installed instead of the simple ones. Besides, not all the surveillance mechanisms can be blinded by Infrared.
Jam the Signals of Wireless CCTV Cameras
It is possible to jam the network of this appliance. If we broadcast a signal of similar frequency, it may compress the network of CCTV security cameras.
Modern wireless systems can be designed to notify the police if a jam is detected.
Above mentioned are few of the strategies to make the system useless. Suggestions to prevent this occurrence are also mentioned. Producers of this appliance need to keep these points in mind. One cannot afford to compromise on the quality of images or security of the surveillance equipment. Otherwise, mounting it is of no use! In fact, it ought to be physically protected. Doing so may provide better protection to a premise.
