Lack of a secured in life especially in urban living paved the way to tighten security coordination between the local police and other government intelligence agencies. These at the same time expanded security surveillance from the simplest ones to the most complicated and expensive methods, to curb injustice and lower down crime rates. Different techniques are popularized and enhanced to deliver accurate evidence for prosecution and investigations.

With the use of video surveillance solution, surveillance is one of the extensively used process to uncover basic information for crime resolution. Though is mode is generally accepted form of legal investigation, surveillance is at the same time used illegally by some notorious individuals who gain profit from stolen information. Here are some popular forms of surveillance techniques.

1) Counter surveillance — This measures are done to avoid surveillance and covert surveillance. Counter surveillance has a set of actions (countermeasures) that is implemented to lessen the risk of surveillance. CCTV system design is a powerful tool in countersurveillance as well.

Popular forms countermeasures are:

* Human countermeasures — human counter agents are used to act against surveillance. Methods commonly used are: leaving the scene without being followed by surveillance assets, getting lost in the crowd of people, and hiding.

*Electronic Method — done by using sweeping and detecting surveillance devices. Sweeping is done by detecting radio waves with a sweeping device. Although some are not effective in detecting bugs which are programmed to shut down.

2) Inverse Surveillance — Made to protect reversalism in surveillance. Examples are common citizens taking photos of police officers, customers taking shots at shopkeepers, and passengers taking a picture at a cab driver who has surveillance cameras within the cab. This method is [/spin]effective|efficient[/spin] in subverting the panoptic looks of surveillance and at the same time, to subvert secrecy by making recordings publicly available.

3) Sousveillance — An inverse surveillance that includes the activity of the surveillance participant. By using a small portable recording devices, video recordings are directly fed to the internet. Extensive IP camera selection is needed to implement this trick correctly. Workshops from microsoft are available to conduct quality sousveillance.

4) Clinical Surveillance — This type is usually done to monitor events that has significance on public health. The occurrence of chronic illnesses and diseases are examples that require this surveillance technique. The method is also efficient in measuring allocations for health care and education. WHO and CDC has moved to create a database for the study to drive policies in health.

Widespread use of video surveillance solution in surveillance conduction paved the way to boost the CCTV technology in many countries. If you are tech savvy and head over heels eager to get yourself a high end camera with video surveillance design, choose the best IP camera your hands can grab. There are different types of cameras available for you ranging from low-level API style to multi-megapixel IP-CCTV cameras. IP camera selection may need your keen eyes to differentiate low end styles from the advance ones.

Here are some considerations you may want to read before selecting your best pick.

1) Resolutions — High resolution cameras will greatly span image details from a regular CCTV cameras. Make sure to look for this feature in your video surveillance feeds as well. Color details can enhance picture clarity

2) Convergence — Choose IP cameras that can be merged with any existing IP structures. Installing your camera is easier this way and you do not need to setup a different scheme for your own. Its as easy as mixing milk and sugar.

3) Reduce Space Requirements — Installing IP cameras that require lesser space compared other CCTV cameras is a major consideration. Choose cameras that does not require large switches and boards.

Aside from these, you may also want to take a look at some disadvantages before purchasing your fave IP camera.

1) Cost — IP Cameras can not be purchased for IP camera is limited compared to regular CCTVs. Though nowadays, this feature is quickly changing.

3) Lack of Standards — The current IP video protocol is not yet stabilized or standardized. Limitations on the video streaming is obvious and not all cameras will work on a certain IP video recording platform. Further developments are being worked to narrow down these incapacities.

4) Bandwith — High bandwidth system requirements limits the full performance of an IP camera. A simple CCTV camera requires only about 3Mbit.

5) Latency — download streaming is usually slow for IP cameras. It takes more time to travel to the server because of the the huge bandwidth.
