How to Safeguard CCTV Security Cameras from Failing to Monitor

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.
