smart security system
An NVR works only with network based cameras. So remember a DVR works with analogue cameras. and an NVR works with network cameras only. In this article, I will be looking only at NVR based systems. This is because DVR based analogue systems are on their way out, they
simply cannot compete with the quality and convenience of network cameras and NVRs. Cameras – Network cameras a. k. a IP cameras are fully digital – the image is sent digitally to the NVR through a network cable instead of an analogue BNC cable as in a DVR based system. This enables resolution higher than 1080p2MP, and currently you can go up to 4MP. The hard drive that will store the recorded video and images – read my detailed guide to selecting the right hard drive. The Ethernet cables needed to connect the cameras to the NVRThe power
adaptors for the cameras read on to see how you can avoid theseNow there are two ways of choosing the different parts above for your dream DIY home security camera kit – what I call going Pro DIY or Easy DIY.

Want to read A Tale Of Two Cities?It’s on the Internet. Have a question about who the third person to land on the moon was?It’s on the Internet. However, want to be exposed to nudity, pedophiles, and thousands if not millions of other social deviants?You bet it’s on the Internet and just a key touch away from your child or grandchild. So, what do we do about this?First, we educate ourselves. Go to The National Center for Missing and Exploited Children website at and download
their study “Online Victimization – A Report on the Nation’s Youth. ” This report will provide an eye opening look at the perils our children are under every
time they access America Online, Compuserve, or the Internet via the local Internet Service Provider. It also provides a telling survey on how parents deal with their children’s use of the Internet. For example, over 85% of parents have talked with their children about being careful talking to strangers on the Net, and 97% of those polled check every now and then on what is on their child’s computer screen. But, only half the parents ever go back and actually check history to ensure the child is indeed staying out of potential problem sites, and only 39% set a limit on the amount of time their child can be on the Internet. Though it appears that parents do realize the potential exposure their children have on the Net, less than 1/2 play a truly diligent role in ensuring their child is protected. Second, we educate others.

m. ET DETROIT AP A cane equipped with the technology that retailers use totag merchandise could help blind people avoid obstacles. An engineering professor and five students at Central Michigan Universityhave created a ''
Smart Cane'' to read electronic navigational tagsinstalled
between buildings to aid the blind in reaching their destinations moreeasily. ''This project started as a way for me to teach students to see andunderstand the ways that engineering can be used for the greater good,''said Kumar Yelamarthi, the professor and project leader. ''We wanted to dosomething that would help people and make our campus more accessible. '' During the spring term, Yelamarthi and five senior engineering studentstested the cane, which is equipped with Radio Frequency Identificationtechnology, similar to what retailers put on products to keep them frombeing stolen. The Smart Cane contains an ultrasonic sensor that is paired with aminiaturenavigational system inside a messenger style bag worn across the shoulder. For the test, the students installed identification tags between twobuildings on the campus in Mount Pleasant, Mich. A speaker located on thebag strap gave audio alerts when the system detected an obstacle and toldthe user which direction to move. Students wearing glasses that simulate visual impairment tested the cane. The students also created a vibrating glove to assist those who are bothvisually and hearing impaired.
