The document discusses 6 threats to CCTV cameras: 1) Damage from lightning, 2) Damage from mischievous people, 3) Vision being blurred by paint or other substances, 4) Hacking, 5) Voltage fluctuations, and 6) Damage from water contact. Suggested solutions include using lightning rods, protective casings, placing cameras out of reach, strong passwords, voltage stabilizers, waterproof housings, and hoods over cameras.
2. 1. Damage to CCTV cameras by lightning
During rainy seasons there is a lot of thunder and lightning which is one of the
major risks a CCTV camera has to face. If lightning falls over a CCTV camera, the
camera can be damaged beyond repair. If such damage occurs to a CCTV
camera then that means loss in many ways. First, loss of the camera and second,
a damaged camera can provide a good opportunity for burglars. Bullet cameras
are more prone to such types of damages as they are the ones generally fixed in
the open.
3. Solution:
Lightning attracts point sources. A CCTV camera can attract lightning as it is more
like a point object. Also, it is an electronic device that provides a double
opportunity for lightning to fall on a CCTV camera. The use of a lightning rod on
the roof of the building could be a possible solution to this problem. Another
solution to prevent damage from lightning is to use well-insulated wires and a
good earthing system. A plastic casing over the CCTV camera can also be of great
help.
4. 2. Damage created by mischievous people
A mischievous person never wants himself to be seen on camera, so the first thing
a person with ill intentions will do is to either break the camera or simply blur its
vision so that he cannot be seen doing wrong. This type of damage can be done
to both indoor as well as outdoor cameras. Outdoor cameras can easily be broken
when hit by a flying stone. Burglars try to break cameras in the first place.
5. Solution:
For outdoor cameras, they should be CCTV fitting on a high enough place so that
it could not be reached. For protection from stones and other hard objects thrown
with the intention to break the camera, a casing can help it out. Metal or hard
plastic frame made like a cage fixed over the CCTV camera can protect it from
breaking.
6. 3. Paint or other things were thrown over the camera to
blur its vision
A most popular idea used by burglars is to blur the vision of CCTV camera by
throwing paint or other stuff on the camera. Once the vision is blocked, a person
can easily get out after having the theft done simply without been seen.
7. Solution:
To fix cameras out of reach of anyone from a distance. The person will have two
options, either he will quit his mission or he will be seen on camera if he comes
close enough to blur its vision.
8. 4. Hacking
A CCTV camera can be hacked which is the worst thing that can happen to a
CCTV camera. Many hackers nowadays use their hacking skills for doing many
mischievous activities. They can hack a CCTV camera and hence see everything
that's going on in a particular place.
9. Solution:
Hacking of CCTV cameras can be prevented by putting in strong passwords to
the wifi network. One should never reveal the password to any outsider. Another
important thing that can be done to prevent hacking is to keep on changing its
password at regular intervals.
10. 5. Voltage fluctuations
Voltage fluctuations may occur sometimes or the other. A very low or very high
supply of electricity can also cause CCTV cameras to get damaged. A sudden
high voltage can cause a short circuit and hence damage the CCTV camera
along with other appliances.
11. Solution
One can use a voltage stabilizer at home so that voltage fluctuations can be
managed and any kind of damage to CCTV or other appliances can be prevented.
use stabilizer. Another solution to the High Voltage problem can be the use of a
fuse in the main switch of the place.
12. 6. Water
Any electronic device be it a simple lamp or a complex closed circuit television
camera, it does get affected when water comes in contact with it. Water due to rain
or other sources like a leakage from somewhere above the camera or somebody's
mischief may cause a damage to CCTV camera.
13. Solution:
Use of waterproof case/housing for the CCTV camera can aid the problem. One
should try to place CCTV cameras in a water-resistant place. A hood over the
CCTV camera can also do to some extent.
