What are the advantages and disadvantages of a CCTV camera?

Answer 1

The advantages of CCTV cameras are that they are kept everywhere. So if a crime is committed the culprit will be eventually caught.

Disadvantages are that they are costly, do not always work(as they are not set up in the right places) and manipulate with people's privacy.

Potential advantages.

The advantages of CCTV cameras are that they are kept everywhere. So if a crime is committed the culprit will be eventually caught.One of the immediately obvious advantages is that the unit is no subject to the failure of any type of wiring. The cameras make use of wireless technology to accomplish the task at hand. This absence of wiring that could fail or be cut means there is much less chance of something going wrong with the unit, or that a clever thief can circumvent the system by severing the connection. Short of ripping the entire camera out of place, there is not much that will slow the unit down.

Another advantage has to do with the clarity of the images that are captured. Most of these wireless units have a high-resolution image that makes it very easy to identify faces and other physical characteristics. This makes the cameras ideal for use as part of the security for research facilities and other establishments. Security personnel can easily monitor all activities within range of the cameras, and clearly note any suspicious or unauthorized behaviour, while getting a clear image of the person engaged in the activities.

Recording is another advantage of these wireless cameras. In times past, storing recordings could be quite a task. From magnetic tape to VHS tapes, storage could become quite a problem. Many of the units on the market today make use of CDR technology, making it possible to store more hours of surveillance on a single disk. This can be crucial for law enforcement officials, as well as persons who are responsible for conducting security in office buildings and manufacturing facilities.

Another advantage of these newer models of wireless surveillance units is that they are usually less expensive than most people would think. In fact, it is possible to purchase these types of cameras at a significantly less amount per unit than many of the wired counterparts on the market today. Coupled with the fact that wireless units make for much easier installation, it should come as no wonder that more and more people are choosing to go wireless for their security camera needs.

Potential disadvantages

The following are some of the potential weaknesses of IP cameras in comparison to other CCTV cameras.

· Disadvantages are that they are costly, do not always work(as they are not set up in the right places) and manipulate with people's privacy.

• Higher initial cost per camera.[citation needed]
• Fewer choices of manufacturers.[citation needed]
• Lack of standards. Different IP cameras may encode video differently or use a different programming interface. This means a particular camera model should be deployed only with compatible IP video recording solutions.[citation needed]
• Technical barrier. Installation for IP camera required a series of complicated network setting including IP address, DDNS, router setting and port forwarding.[citation needed] This is very difficult for most users to do without help from an IT technician.
• Lower dynamic range - i.e. reduced ability to cope with low light and high contrast scenes.[citation needed]

Vulnerable to hacking, and hoaxing via internet (numerous instances of false bomb threats being called in as hoaxers watch on web); criminals can hack into a facility's CCTV system to observe security measures and personnel, thereby facilitating criminal acts and proving the IP technology to be counterproductive
