A major city in Southern Taiwan planned to upgrade its inner city surveillance system to provide safety and security for its population in 38 districts. The project would include upgrading to megapixel solutions that can be fully integrated with the control center, branches, sub-station junctions and the existing IT infrastructure.
To ensure the protection of citizens, city surveillance is the most direct and productive method for any government. However, due to a large geographic coverage with thousands of cameras, the installation, integration, stability and reliability issues are very difficult to overcome. Surveon has completed a professional project with 3,000 IP camera installations and fulfilled requirements of high stability, reliability and an extremely low rate on the return merchandise authorization(RMA).
Customer
A major city in Southern Taiwan planned to upgrade its inner city surveillance system to provide safety and security for its population of 2.8 million in 38 districts. The project would include upgrading to megapixel solutions that can be fully integrated with the control center, branches, sub-station junctions and the existing IT infrastructure.
CHALLENGES
High Reliability
To maintain a project with 3,000 cameras spreading across the city is not an easy task; any RMA is costly for the SI and inconvenience for the customer. Especially many cameras are installed in the intersections and at higher points, it time-consuming and more resources required to evaluate the situation and conduct the repairs.
Wide Monitoring Area
The widely distributed network areas, scalable architecture and maintenance issues were the challenges the SI first faced in this project. Environmental factors such as heat, humidity, and temperature changes were also obstacles to overcome.
Complex Lighting Conditions
Every corner is required to be monitored at all times to protect people, prevent potential security threats and provide evidence whenever needed. However lighting changes can affect the camera performance.
Customized Features
Often there are special requirements and restrictions for city surveillance; for example, limited bandwidth but stable streaming required, different lighting conditions but clear visibility demanded, remote storage, offline recording and so on.
SOLUTIONS
3 Megapixel Cameras
Surveon 3 megapixel cameras provide the high image quality with low light performance. With a maximum 2048x1536 resolution, Full HD real-time video recording, and features such as DC iris and WDR, the cameras are the ideal solutions for high-level security applications.
Furthermore, Surveon's 2nd generation 3 megapixel real-time HDR cameras have extended the real-time performance to 3 megapixel at 30 FPS. The series also features HDR with over 100dB, giving installers a high quality and real-time performance well beyond what the standard WDR and DWDR can offer. Along with other advanced functions including H.264 high profile, ROI video cropping, enhanced 2D/3D noise reduction, and edge enhancement, Surveon 3 megapixel real-time HDR cameras are the excellent choice for professional applications such as city surveillance.
Industrial-grade Design
Every Surveon's product is in-house designed and manufactured with industrial-grade components and backed with 3-year warranty. More than 300 hours of verifications and validations have been carried out before production in the self-own, ISO 9001 and ISO 14001 certified production site. Moreover, Surveon's products are under strict examinations, full QA processes and 8+ hour-burn-in tests before any delivery.
PROFESSIONAL FEATURES
Offline recording
To compensate the limited bandwidth issue, Surveon cameras are equipped with the SD slot and the offline recording capability which can automatically store the video to the SD card during downtime and resend the video to the NVR when the network is recovered. In addition, the balance of bandwidth between live view and offline video resending can be achieved and network bandwidth control.
Advanced image settings
Two profiles are available for different image parameters on the subjects of iris, shuttle speed, AGC, brightness, contrast and DNR levels subjected to change automatically with the day and night settings to ensure a fixed image quality under different lighting environments.
Network detection
This function identifies the best firmware configurations for the network environment.
Internet small computer system interface (ISCSI) supported
With ISCSI, recording can be made directly without any integration problems for future storage expansions.
