Good color reproduction: Ensuring that the color of the image is real and natural helps to accurately judge the state and characteristics of the object. For example, when identifying the color of traffic lights and vehicle colors, accurate color reproduction is crucial.
Low-light performance: It can also provide clearer images in low-light environments, such as at night and in tunnels. Good low-light performance can be achieved by using high-performance image sensors and advanced night vision technology.
Real-time:
Low-latency transmission: The transmission of video and data should have a low latency so that the monitoring personnel can understand the real-time status of the vehicle in a timely manner. The delay time should generally be controlled within a few hundred milliseconds to ensure that a quick response can be made in an emergency.
Continuous monitoring: The system should be able to monitor continuously and stably without long-term interruptions or freezes. This requires reliable network connection and efficient data processing capabilities.
Multi-angle monitoring:
Multiple camera coverage: Multiple cameras should be equipped to achieve comprehensive monitoring of different angles of the vehicle, including the front, rear, sides and inside the vehicle. For example, the front camera is used to record driving conditions, the rear camera is used for reversing assistance and monitoring the rear vehicle, and the in-car camera is used to monitor driver behavior and passenger status.
Adjustable viewing angle: The camera's viewing angle should be adjustable to meet different monitoring needs. For example, the camera's viewing angle can be adjusted to expand the field of view in narrow sections, and it can be adjusted to a more focused view of the road ahead when driving at high speeds.
2. Wireless transmission performance
Stability:
Reliable connection: During vehicle driving, whether in different environments such as cities, rural areas or mountains, a stable wireless connection can be maintained. Avoid monitoring failure due to signal interruption, which affects the safety management of the vehicle.
Anti-interference ability: It has strong anti-interference ability and can work normally in complex electromagnetic environments. For example, there are a large number of radio signals and electronic devices in the city, and the system should be able to effectively resist these interferences to ensure the stability of data transmission.
Bandwidth and speed:
Sufficient bandwidth: It can support the real-time transmission of high-definition video, and can also transmit other data, such as the vehicle's location information, driving speed, fuel consumption, etc. According to different application scenarios and monitoring requirements, the bandwidth should be able to meet the requirements of simultaneous transmission of multiple videos.
Fast data transmission: Ensure that videos and data can be uploaded to the monitoring center in time for real-time analysis and processing. For some emergency situations, such as vehicle accidents and failures, fast data transmission can provide key information for rescue and processing.
Network adaptability:
Support multiple networks: It should be able to adapt to different wireless network environments, such as 4G, 5G, Wi-Fi, etc. In different regions and scenarios, it can automatically switch to the best network connection method to ensure the continuity of monitoring.
Roaming function: For long-distance transport vehicles or vehicles traveling across regions, the system should have good roaming functions to ensure seamless switching between different network coverage areas without affecting the continuity of monitoring.
3. Data storage performance
Local storage:
Large-capacity storage: The monitoring equipment on the vehicle should have a certain local storage capacity so that it can continue to record video and data when the network is interrupted or cannot be connected to the monitoring center. The storage capacity should be reasonably configured according to the monitoring needs and the use of the vehicle, and generally be able to store video data for at least several days.
Reliability: The local storage device should have high reliability and be able to work normally in harsh environments such as vibration, high temperature, and low temperature of the vehicle. At the same time, it should have data protection functions to prevent data loss or damage.
Remote storage:
Cloud storage support: The system should be able to upload videos and data to a remote server for storage so that they can be queried and played back at any time. Cloud storage should have high security and reliability to ensure the confidentiality and integrity of the data.
Data backup: To prevent data loss, remotely stored data should be backed up regularly. The backup strategy should be formulated based on the importance of the data and storage requirements to ensure that data can be quickly restored in the event of an accident.
4. Functional performance
Alarm function:
Abnormal detection: It can monitor the status of the vehicle in real time, and immediately issue an alarm signal when an abnormal situation occurs, such as speeding, sudden braking, collision, etc. The alarm method can include sound, light, SMS notification, etc., so as to promptly remind the driver and monitoring personnel to take corresponding measures.
Tamper detection: The system should have anti-tampering function, and can issue an alarm in time when someone tries to destroy or tamper with the monitoring equipment. This can be achieved through encryption technology, hardware protection, etc. to ensure the authenticity and reliability of monitoring data.
Positioning function:
High-precision positioning: Accurately determine the location of the vehicle, and the positioning accuracy should be within a few meters. It can be achieved through a variety of positioning technologies such as the Global Positioning System (GPS) and the Beidou Satellite Navigation System to provide accurate location information for vehicle dispatch, management and rescue.
Real-time tracking: The vehicle's driving trajectory can be tracked in real time, and the monitoring personnel can view the vehicle's location and driving route at any time. This is very important for vehicle management in industries such as logistics and public transportation.
Remote control function:
Equipment parameter setting: The monitoring personnel can set the parameters of the monitoring equipment on the vehicle through remote control, such as adjusting the camera's viewing angle, setting the alarm threshold, etc. This can improve the flexibility and adaptability of the system and meet different monitoring needs.
Equipment restart and troubleshooting: When the equipment fails, the monitoring personnel can restart the equipment or perform some simple troubleshooting operations through remote control to reduce the time and cost of returning the vehicle for repair.
5. Security performance
Data encryption:
Transmission encryption: Encrypt the transmission of video and data to prevent illegal theft or tampering. Advanced encryption algorithms, such as AES encryption, can be used to ensure the security of data during transmission.
Storage encryption: Both locally stored and remotely stored data should be encrypted, and only authorized personnel can access and read the data. This can effectively protect the privacy information of vehicles and users.
Access control:
User authority management: Strict authority management is performed on users of the system, and users of different levels have different access rights. For example, administrators can perform system settings and device management, and ordinary users can only view videos and data.
Identity authentication: Users should perform identity authentication when logging into the system to ensure that only legitimate users can access the system. Multiple authentication methods such as username/password, fingerprint recognition, and facial recognition can be used to improve the security of the system.
Anti-attack capability:
Firewall protection: The system should have a firewall function to prevent attacks from external networks. The firewall can prevent illegal access and malware intrusion, and protect the safe and stable operation of the system.
Vulnerability management: Regularly scan and repair the system for vulnerabilities, and update the software version in a timely manner to ensure that there are no security vulnerabilities in the system. At the same time, an emergency response mechanism should be established to quickly take measures to deal with security incidents.
