Smile, if you're in downtown Houston!
The city is installing 250 to 300 cameras at downtown intersections in an effort to prevent and fight terrorism and crime, part of a security initiative sponsored by the U.S. department of Homeland Security.
The cameras, which the city began installing in earnest this summer, already have helped police catch car burglars in the act, said Dennis Storemski, the city's director of the Office of Public Safety and Homeland Security. Eventually, he said, the cameras could be used to allow dispatchers or officers approaching a crime scene to survey what's happening from their patrol vehicles before they arrive.
"The intent is to protect critical infrastructure and prevent terrorism," he said. "Experience has shown that when people plan terroristic acts, they plan and they do dry runs, so what we would be looking for is suspicious activity around certain locations. And for any crimes, you can go back and look at the video and identify the perpetrators."
More than 50 cameras already have been installed around the George R. Brown Convention Center, Discovery Green Park, the theater district and Minute Maid Park. Every downtown intersection will be equipped with a camera. Eventually, Storemski said, the program may be expanded to include the Reliant Stadium complex, the Port of Houston, even some city parks where festivals frequently are held.
'Big government'
The footage can be monitored in real time by police and after the fact through a computer network built during the past three years.
The cameras will allow police to monitor any scene from several viewpoints at once rather than having to staff events with officers surveying the scene in binoculars, he said.
For some who passed by the northeast corner of Milam and Texas early Wednesday, where a crew installed one such surveillance device, the idea was alarming.
"I'm not in favor of it," said Mike Wells, who was walking to his office across the street.
The cost of operating the cameras, as well as their capability to invade privacy, was troubling, he said.
"That's big government watching our every move," he said.
Chris Goldsmith, who works downtown, said he was most concerned with the cost to taxpayers of installing and operating the cameras.
Public spaces not private
Privacy, he said, is not necessarily a concern because "in the public you've got no expectation of privacy."
Storemski sounded a similar note, saying that all the cameras are in public spaces where people should be aware that their actions are not private.
"We live in an age right now where there's really no expectation that there would be no video in a public space," he said. "Everybody that has a cell phone has a video camera. This happens all the time. We're just doing it for public safety purposes."
The city has spent about $14 million in federal grant funding on the camera program, which it expects to finish by the end of January. The money comes from Urban Area Security Initiative funds doled out annually by Homeland Security to regions across the country, Storemski said.
In recent years, Houston has received an estimated $18 million to $20 million, money to spend on initiatives to prevent and detect terrorism.
Other projects include funding an interoperable radio system and the video network that can sustain the cameras, make footage shot by private cameras accessible to police and even take footage from a helicopter and allow first responders to see it. The latter particularly has been useful for fighting fires, Storemski said.
ID'd subway bombers
Cameras in public spaces already have proven successful in major worldwide incidents, such as identifying suspects in the 2005 subway bombings in London, he said.
In Chicago, dispatchers already have access to cameras and can provide descriptions to police arriving at a scene.
Some Houstonians on Wednesday responded favorably to the camera program.
Julio Flores, a waiter at a downtown skyscraper, said he felt more comfortable knowing that surveillance camera footage could be used to solve crimes or to track suspects.
Judith Hanson, who was visiting downtown to watch her daughter's performance at the Wortham Center, said the cameras could provide comfort to women who come to the area.
"Just knowing that there is a camera just makes me feel a little bit safer," she said.

Shedding Some Light on Resolution
Resolutions
Resolution in an analog or digital world is similar, but there are some important differences in how it is defined. In analog video, an image consists of lines or TV-lines since analog video technology is derived from the television industry. In a digital system, an image is made up of square pixels.
NTSC and PAL resolutions
NTSC (National Television System Committee) and PAL (Phase Alternating Line) resolutions are analog video standards. They are relevant to network video since video encoders provide such resolutions when they digitize signals from analog cameras. Current PTZ network cameras and PTZ dome network cameras also provide NTSC and PAL resolutions since such cameras today use a camera block (which incorporates the camera, zoom, auto-focus and auto-iris functions) made for analog video cameras, in conjunction with a built-in video encoder board.
In North America and Japan, the NTSC standard is the predominant analog video standard, while in Europe and many Asian and African countries, the PAL standard is used. Both standards originate from the television industry. NTSC has a resolution of 480 lines and uses a refresh rate of 60 interlaced fields per second (or 30 full frames per second). A new naming convention, which defines the number of lines, type of scan and refresh rate, for this standard is 480i60 (“i” stands for interlaced scanning). PAL has a resolution with 576 lines and uses a refresh rate of 50 interlaced fields per second (or 25 full frames per second). The new naming convention for this standard is 576i50. The total amount of information per second is the same in both standards.
When analog video is digitized, the maximum amount of pixels that can be created is based on the number of TV lines available to be digitized. The maximum size of a digitized image is typically D1 and the most commonly used resolution is 4CIF.
When shown on a computer screen, digitized analog video may show interlacing effects such as tearing and shapes may be off slightly since the pixels generated may not conform to the square pixels on the computer screen. Interlacing effects can be reduced using deinterlacing techniques, while aspect ratio correction can be applied to video before it is displayed to ensure, for instance, that a circle in an analog video remains a circle when shown on a computer screen.

VGA resolutions
With 100% digital systems based on network cameras, resolutions that are derived from the computer industry and that are standardized worldwide can be provided, allowing for better flexibility. The limitations of NTSC and PAL become irrelevant.
VGA (Video Graphics Array) is a graphics display system for PCs originally developed by IBM. The resolution is defined as 640x480 pixels, which is a common format used by non-megapixel network cameras. The VGA resolution is normally better suited for network cameras since VGAbased video produces square pixels that match with those on computer screens. Computer monitors can handle resolutions in VGA or multiples of VGA.
|
Megapixel resolutions
A network camera that offers megapixel resolution uses a megapixel sensor to deliver an image that contains one million or more pixels. The more pixels a sensor has, the greater the potential it has for capturing finer details and for producing a higher quality image. Megapixel network cameras can be used to allow users to see more details (ideal for identification of people and objects) or to view a larger area of a scene. This benefit is an important consideration in video surveillance applications.

Megapixel resolution is one area in which network cameras excel over analog cameras. The maximum resolution a conventional analog camera can provide after the video signal has been digitized in a digital video recorder or a video encoder is D1, which is 720x480 pixels (NTSC) or 720x576 pixels (PAL). The D1 resolution corresponds to a maximum of 414,720 pixels or 0.4 megapixel. By comparison, a common megapixel format of 1280x1024 pixels gives a 1.3-megapixel resolution. This is more than 3 times the resolution that can be provided by analog CCTV cameras. Network cameras with 2-megapixel and 3-megapixel resolutions are also available, and even higher resolutions are expected in the future.
Megapixel resolution also provides a greater degree of flexibility in terms of being able to provide images with different aspect ratios. (Aspect ratio is the ratio of the width of an image to its height.) A conventional TV monitor displays an image with an aspect ratio of 4:3. Bolide megapixel network cameras can offer the same ratio, in addition to others, such as 16:9. The advantage of a 16:9 aspect ratio is that unimportant details, usually located in the upper and lower part of a conventional-sized image, are not present and therefore, bandwidth and storage requirements can be reduced.
