A network camera, often also called an IP camera, can be described as a camera and computer combined in one unit.

The main components of a network camera include a lens, an image sensor, one or several processors, and memory. The processors are used for image processing, compression, video analysis and networking functionalities.

Home Like a computer, the network camera has its own IP address,
is connected directly to a network and can be placed wherever there is a network connection.

SpyCameras.com has IP cameras that deliver performance, flexibility, and convenience for your surveillance needs.

The Benefits of IP Cameras

IP cameras are able to function on a wireless network. Initial configuration has to be done through a router; after the IP camera is installed it can then be used on the wireless network. These cameras are used in navigation purpose in defence forces.

Cost-advantage for larger systems. Studies show that for systems with fewer than 16 cameras, analog technology is cheaper, between 16 and 32 they are equal, and beyond 32 cameras, IP-based systems are more cost-effective.

Surveillance Network

Houston surveillance network ties together hundreds of cameras‎

Sitting behind a stacked bank of monitors in a small conference room, Houston senior police officer Joe Mireles can survey much of the city's central business district with a click of his mouse. One screen watches a group of children excitedly splashing through the waterworks at Tranquillity Park, while another zooms in on foot traffic outside the Dollar Store at Main and Walker. One monitor displays a live feed from along Metro's light rail line, and the adjacent screen spies on a quiet corner of Eleanor Tinsley Park. Mireles has tapped into the city's fast-growing surveillance camera network that has been installed by the Mayor's Office of Public Safety and Homeland Security, one that has received far less attention than the controversial red-light camera system.

So far, drawing on $14 million in federal grants, the office has installed 330 cameras, of which 266 are providing live feeds to the city network. That network is also tied into 260 cameras installed inside City Hall and other city buildings.

TranStar cameras on freeways and Metro's rail-line surveillance are also hooked up to the system. Next stop is reaching an agreement to tie into security cameras monitoring streets in the Texas Medical Center, officials said.

Chief Dennis Storemski, a former HPD executive chief who runs the mayor's public safety office, describes the current system as "a work in progress'' and envisions a hybrid government and private network that can command the collective view of thousands of surveillance cameras.

"So as long as I get money, I'm going to keep putting cameras up - there is not a targeted number," said Storemski, who notes that New York City's surveillance system utilizes some 2,000 cameras. "So we have a long way to go.''

Houston's journey into the ranks of cities that keep a close watch on their public spaces has been a gradual one - and reviews are mixed. Civil rights activists view the network with suspicion, while others believe it is a worthwhile use of modern technology in a time of tightened budgets.
