Digital Surveillance Systems
CCTV Surveillance Systems
Today, the presence of CCTV surveillance systems has become very popular. High traffic areas that promote security, such as shopping malls and department stores, will typically have a system in use. Due to their efficiency in curbing theft, they have begun to be used in the home as well.
How do they work?
CCTV surveillance systems are almost like having a dedicated television, which safeguards your home from thefts and break-ins. Using a network at home, the security surveillance footage can be broadcasted easily. However, as opposed to broadcast television the CCTV surveillance systems are directly connected to one another through wireless networks or cables. These systems are being used increasingly across airports as well as casinos.
Prevention of Crime
By using CCTV surveillance systems the crime rate has been curtailed significantly. For example, such CCTV surveillance systems function as deterrents to thieves and convicts, as research in the UK and US has shown. CCTV surveillance systems have captured footage that has been used as evidence in a court of law. Many law enforcement agancies have been helped by the use of these security systems in detecting crimes and the presence of thieves.The use of CCTV surveillance systems has helped the police in catching escaping criminals.
Increased Home Security
The efficiency of these CCTV surveillance systems cannot be doubted as the crime rate has dropped since their installation. The significance of having such CCTV surveillance systems in the home is now being realized by homeowners. A better peace of mind and assurance that your home is safe can be obtained by using one of these systems. With CCTV surveillance systems, homeowners can instantly detect if a thief is trying to gain entry into their home or not. A thief can be deterred from entering a house with the presence of visible cameras. It is because their actions will be recorded on the cameras of the CCTV surveillance systems and they can be caught by the police easily.
CCTV surveillance systems provide high quality images and can be easily installed across as many as 16 rooms in the house. You can choose to keep track of specific places such as the yard, garage, front door or even the mailbox. You can get real-time information on suspicious activities by monitoring specific areas of your home. You can keep your home safe and secure by using CCTV surveillance systems.

they're all basically the same, i'd go with the DXG
Mimicking the brain, in silicon (MIT)
For decades, scientists have dreamed of building computer systems that could
replicate the human brain’s talent for learning new tasks.
MIT researchers have now taken a major step toward that goal by designing a
computer chip that mimics how the brain’s neurons adapt in response to new
information. This phenomenon, known as plasticity, is believed to underlie
many brain functions, including learning and memory.
With about 400 transistors, the silicon chip can simulate the activity of a
single brain synapse — a connection between two neurons that allows
information to flow from one to the other. The researchers anticipate this
chip will help neuroscientists learn much more about how the brain works, and
could also be used in neural prosthetic devices such as artificial retinas,
says Chi-Sang Poon, a principal research scientist in the Harvard-MIT Division
of Health Sciences and Technology.
Poon is the senior author of a paper describing the chip in the _Proceedings
of the National Academy of Sciences_ the week of Nov. 14. Guy Rachmuth, a
former postdoc in Poon’s lab, is lead author of the paper. Other authors are
Mark Bear, the Picower Professor of Neuroscience at MIT, and Harel Shouval of
the ...
