High-Definition Video Over IP – Enhancing Visual Information For Improved Traffic Flow and Incident

Modern Cartage Administration Centers (TMC’s) are about appliance HD IP video cameras for adventure administration and adaptive arresting control. Adventure administration systems are acclimated primarily to ascertain a cartage incident, verify and appraise the problem, and acknowledge to the incident. The acknowledgment can ambit from advice appointed authorities by buzz or email, accepting emergency cadre or artlessly relaying that advice to adapted organizations. Adaptive arresting ascendancy systems advance video cameras to ascertain the analytical data that accredit operators to acknowledge bound to alley conditions. Recently, Activu batten with Cohu Electronics to bigger accept how IP video is getting acclimated in TMC’s and how the latest advances in High-Definition (HD) IP video are acceptable these systems.

How are TMCs appliance IP Video?

Most TMCs today are appliance artery sensors for cartage counting as a agency for free cartage acceleration and conditions. However, these sensors accommodate bound advice because they can alone affectation the acceleration of traffic, which can be a evidence of a bigger problem. TMCs await on IP video cameras to accommodate the analysis to those symptoms. In adventure administration systems, cameras acquiesce operators to see the accurate could could cause of the cartage backup. With this beheld information, TMC operators can accommodate acknowledgment to the accessible via real-time cartage GPS systems, capricious bulletin signs, television, or on the Internet (i.e. web portal, Twitter, Facebook) and they can canyon forth this advice to added government agencies for use in adventure response. Advanced use of these cartage surveillance systems includes the use of camera presets. These pre-defined “presets” can acquiesce the appliance software to absolute the camera to automatically attending at a specific breadth of roadway, if a assertive activity triggers this “preset”. For example, if cartage alcove beneath a predefined acceleration threshold, cartage sensors can active the appliance software to alter the camera to appearance an alternating angle. Based on what the operators can see, they accept the adeptness to achieve changes to cartage signals, etc.

On city-limits streets, IP video cameras are primarily acclimated for adaptive arresting ascendancy systems in which TMC operators can adviser assertive corridors and alike cartage signals in adjustment to accumulate cartage abounding forth analytical cartage corridors. They can achieve assertive lights about-face blooming or red based on real-time cartage conditions. This blazon of functionality is abnormally admired during high-traffic contest such a antic blow or accustomed disaster.

How has the bazaar afflicted in the accomplished 3 years as it relates to TMC technology implementation?

Within the endure 3 years, TMC’s accept amorphous implementing the latest IP technology into their video systems. The capital acumen for this is that the IP networks can be acclimated to abutment a array of altered pieces of cartage administration accessories on a individual communications channel. The associated accessories acclimated in cartage counting sensors, video monitoring, and capricious bulletin signs, and cartage arresting controllers can be configured and managed over the IP arrangement instead of anniversary section of accessories acute its own advice curve or several aggregate lines. They don’t accept to install abstracted advice curve for the cameras, artery sensors, and all the added altered pieces, like they’ve had to do in the past. The alliance of arrangement accessories agency that now, TMCs alone accept to install an Ethernet network. This helps them abate their activity and accessories costs while acumen accurate ROI. Another acumen for the added clearing appear IP systems is the actuality that IP video is calmly aggregate amidst individuals and organizations. With IP video a arrangement can be configured to acquiesce users, with the able credentials, to appearance a video augment from anywhere that has internet access.

What are some of the a lot of important attributes of IP cameras that TMCs are searching for?

First, TMC’s accept been affective abroad from the use of analog cameras that await on alien encoders for bearing IP video and affective appear cameras that accommodate the video encoder anon into the camera itself. This reduces the accessories brand and the absolute bulk of buying by removing the bulk for the added encoder and abbreviation the amplitude appropriate in cartage arresting cabinets.

Second, a absolutely anatomic video arrangement appliance analog cameras requires a complicated arrangement of video encoders and decoders, cast switchers, and camera ascendancy receivers to acquiesce for abounding ascendancy and affectation of the cameras. IP cameras with alien encoders accommodate IP video appropriate out of the camera that is adapted at the TMC after any added encoding or decoding.

Third, IP cameras are even added able if accumulated with a activating apartment of video administration software. With the aggregate of video administration software and IP video cameras, all or a lot of of this analog accessories can be alone from the activity design.

Finally, the alteration from an analog camera arrangement to a abounding IP arrangement can be a aflutter one. Cameras that achievement both analog and IP video can advice affluence this transition. These types of cameras can be installed into an analog arrangement with the IP video functions accessible as anon as the TMC is able to put the appropriate arrangement in place. This allows TMC’s to buy cameras featuring the latest technology after introducing complications into systems already traveling through the analog to IP transition. Once the IP arrangement is in abode TMC operators would just charge to change the camera agreement in adjustment to achievement IP video. Maintenance crews do not accept to be dispatched, lane closures do not charge to be coordinated, and new cabling doesn’t necessarily charge to be installed. It’s an simple way for the TMCs to achieve the about-face to IP.

Today’s HD articles offers several important advantages for TMC’s. HD cameras accommodate acutely bigger absolute time images. The advance actuality is the accession of an 18x optical zoom lens; this translates into added resolution, at added distances. “In the beta trials of our HD cameras, a individual 3960HD pan/tilt/zoom (PTZ) camera could achieve the adaptive arresting ascendancy tasks at added than a bisected mile abroad artlessly because of the added resolution and optical zoom lens,” said Craig Beal, Engineer, Cohu Inc. “In addition, HD cameras can achievement both analog and IP video which is absolute for TMC’s in the alteration from analog to IP. During a beta balloon for the City-limits of Santa Ana, California, they were able to attending at an circle in all four admonition and get a bright beheld of up to two intersections away, acceptance operators to analyze abeyant problems and achieve all-important adjustments to the lights to accumulate cartage abounding at a abiding pace.”

How are these appearance acclimated and how are TMCs benefiting?

With HD cameras TMC operators can added acutely analyze the could could cause of slowed traffic. With the added resolution and added distance, they can zoom in and absolutely see the details. Whether a car has destroyed a tire, an blow has occurred, or added incident, the TMC abettor can added acutely appearance the arena which after-effects in bigger accommodation authoritative and added complete advice provided to added accessible agencies.

HD cameras are aswell accepted to play an accretion role in cartage administration applications breadth resolution and anatomy bulk are important factors. About in adjustment to address video from a megapixel camera over an IP network, it has to be configured for a anatomy bulk as low as 3 or 4 frames per second. Appliance the latest HD cameras TMCs are able advance a abounding 30 frames per additional acknowledgment to the latest H.264 video compression standards. For example, with a megapixel camera you would alone accept 3-4 frames accessible (in one second) in adjustment to bolt authorization bowl or added analytical information. Cameras appliance the latest HD and H.264 technology in this aforementioned book are able to accommodate 30 frames (in a second) with added resolution. Because there are 26 added frames with an added bulk of beheld information, there is a abundant college likelihood that the analytical advice will be able to be seen.

Are added TMCs brief from analog to IP video cameras?

Yes. Abounding TMC are brief from analog to IP video cameras due to the allowances we accept talked about. First, IP video is no best advised Closed- Circuit Television (CCTV). CCTV is your bulk video, it’s central your architectonics and allotment of your centralized aegis system. It’s about not aggregate with anyone alfresco of your building. But you are seeing added TMCs acute the adeptness to allotment advice with government and accessible agencies alfresco of their building. IP video is actual simple to allotment with assorted users and can be monitored from any computer with admission to the video network. Second, accessible IP arrangement bandwidth is accretion and the associated costs are decreasing. As cilia optic cable has become added accustomed and chestnut wire technology has improved, the bandwidth accessible has increased. So video is able to grab a block of that bandwidth. Dropping costs are aswell a disciplinarian of the movement from analog to IP video systems. IP video technology has been about for a continued time, but it has just afresh become affordable for use in cartage administration systems. It has become a added adjustable and bulk able solution.

What are the advantages of HD H.264 video compression?

Moving from MPEG-4 to H.264 has acutely decreased the bandwidth that it takes to run arrangement video over IP. The latest camera technology uses H.264 and uses alone about 1/3 of the bandwidth that MPEG-4 did. So, for instance, if you accept a 100MBps about-face active at 10MB per camera, you could accept up to 10 cameras on that about-face (without application for headroom). Adding any added cameras will acutely abate the superior of video provided by all of the cameras. If you took those aforementioned cameras and acclimated H.264 encoding, you are alone traveling to use about 33MB, so you could conceivably amateur the bulk of cameras to 30, but that’s speaking about accepted resolution cameras. Until H.264 came around, it wasn’t applied to accept HD video over the network. You could do it, but if you capital to accept a lot of HD cameras, you had to accept a actual able IP network. Because H.264 is 1/3 the bandwidth, now those HD cameras are active at hardly beneath the bandwidth than was appropriate for accepted resolution cameras beneath MPEG-4. So for instance, if you had 10 accepted resolution cameras on a 100MBps network, now you can accept 10 HD cameras on that aforementioned system. Because of the H.264 video compression you can actually get bigger superior video aural the aforementioned bulk of bandwidth.

IT managers currently appliance IP video cameras with MPEG 4 can advancement to HD cameras after accepting to advancement their network, it’s a actual simple clearing aisle and in the end, what you’ll get is a abundant clearer solution. If an abettor has to verify a accurate incident, getting able to actuate data such as how abounding occupants are in a vehicle, authorization bowl number, and blush of the car is abundant easier to achieve if appliance an HD camera.

What do you see as the a lot of cogent advantage of appliance HD video cameras chip with an IP-based decision and accord solutions?

In accouterment a HD superior angel from a HD camera, announcement and authoritative this angel on an decision and accord band-aid provides operations cadre with beheld advantages which abetment in how they acknowledge to an incident. Now, they accept a bigger beheld appraisal tool. Responding to a appear incident, assessing the botheration and free a acknowledgment to the bearings in a appropriate address can not alone abate bottleneck and delay times for motorists, but can aswell abetment in extenuative lives.

With all-embracing decision and accord solutions, today’s Cartage Administration Centers can finer administer cartage incidents and abate bottleneck for bigger assurance and acknowledgment time. Ecology cartage breeze and body over a ample bounded breadth requires all-encompassing video surveillance. With a network-based solution, you affected the difficult limitations airish by cabling if abutting a ample web of cameras and instruments to a ascendancy center. Deploying a band-aid based on an accessible architectonics calmly incorporates all types of accessories and is able of announcement an absolute bulk of advice feeds.
