Surveillance system solution for road traffics:

eSSL Security

Surveillance solution uses sophisticated devices and technologies to build a stable and reliable video surveillance system and ensure the safe and standard operation of traffics. This solution provides interfaces for connecting to standard devices and other systems.

Traffic cameras are an innovative and extremely functional use of video surveillance technology. You've seen their footage during traffic reports on the TV news. They're atop traffic signals and placed along busy roads, and at busy intersections of the highway. Whether they're recording traffic patterns for future study and observation or monitoring traffic and issuing tickets for moving violations, traffic cameras are an explosively popular form of video surveillance.

Traffic surveillance includes the urban surveillance system, high-definition checkpoint surveillance system, bus and taxi surveillance system, and high-definition e-Police system. With these surveillance systems, the Solution provides real-time traffic monitoring and releases traffic information to notify drivers of road conditions. To meet the requirements of different transportation means, Intelligent Traffic Surveillance Solution provides the urban road transportation solution, highway transportation solution, and railway transportation solution, which helps optimize an existing transportation infrastructure, alleviates traffic bottlenecks, and maximizes traffic efficiency.

 

Advantage of traffic surveillance camera:

Aid commuters - Traffic cameras placed at common congestion points on highways, freeways, interstates and major arteries often share feeds with news outlets - both radio and TV, which in turn pass them onto commuters in the form of traffic reports. Normally, traffic flows do not vary much from day to day, but in the event of a severe accident or road closure, a traffic alert can be extremely valuable for a time-crunched commuter.

Valuable data - Traffic cameras that simply monitor car flows on roads and major arteries are often maintained by state departments of transportation. Along with monitoring the roads for accidents or major closures, footage from traffic cameras is influential in decisions regarding future road development and construction.

Enforce laws - Cameras used to enforce speed and red light laws are effective in catching moving violations and issuing tickets.

Encourage safe driving - Visible surveillance cameras posted at intersections can encourage safe driving habits and discourage moving violations.

How Does an IP Camera Work?

HB IP Camera

The IPCamera or Network Camera is an all-in-one system with built-in CPU and web-based solutions providing a low cost solution that can transmit high quality video images for monitoring. The system can be managed remotely, accessed and controlled from any computer over the Intranet or Internet via a web browser.

Instead of transmitting video over a video cable to a monitor or DVR, an IP Camera transmits digital video over a data connection; Ethernet, USB, Wi-Fi, etc. Everything required to transfer images over the network is built into the unit. It is connected directly to the network, just like any other network device, like a printer or scanner. Depending on what type of camera it is, it may save video to an attached memory source, connect to another device on the network for storage, or stream captured video to the internet.

An internet camera captures images the same way any digital camera does. What makes it different is its ability to compress the files and transmit them over a network. If a building is equipped with a network, the necessary infrastructure is already in place to install network cameras. If adding one or a few cameras, a user may use a decentralized network camera, one that has its own control interface and storage medium built in. When installing multiple network cameras it can be wise to use a centralized network camera, which requires a Network Video Recorder (NVR).

An NVR is a program that can store video from network cameras and allow for viewing of multiple cameras at once. It is similar to a Digital Video Recorder (DVR), but while a traditional DVR is responsible for encoding and processing video from component cameras, NVR depends on the cameras to encode their video, simply storing it and allowing for centralized remote viewing. NVR software can be installed on a dedicated device with its own operating system or on an existing computer. There are hybrid systems available that can accept both IP and analog inputs. These will often allow analog cameras to be viewed remotely along with any network cameras.

There are 3 types of networks in common use for IP Camera applications:

·     Wired networks will connect to a broadband modem or router through Ethernet cables (RJ45, CAT5, and CAT6). These are the fastest and most secure way to connect, removing the chance of signal interception and interference.

·     Wireless networks use a Wi-Fi router to transmit data to and from a wired modem. They transmit data at a slower rate than a wired network, and are at increased vulnerability to unauthorized access, though this can be mitigated through the use of encryption. The decreased security is balanced by the ease of setup and customization of a wireless network.

·     Cellular network access tends to be the slowest of the three, but is more secure than Wi-Fi. If the cameras themselves are equipped with cellular transmitters, they don't even require a LAN to be in place, so there's virtually no installation required. These types of cameras, however, can be quite expensive, especially when transmitting high quality video.

Conclusion:

A network camera has its own IP address. It is connected to the network and has a built-in web server, FTP server, FTP client, e-mail client, alarm management, programmability, and much more options. A network camera does not need to be connected to a computer; it operates independently and can be placed wherever there is an IP network connection.
