8000

500

256

128

2. Huawei eSpace IVS intelligent video surveillance platform management, media access device, internet and other network modules can be co-located on a server to save space and cost, also independently deployed, multiple cluster to improve performance and throughput.

TRUE

FALSE

3. The video surveillance project in the park should focus on () (Multiple Choice)

Government park monitoring

Supermarket chain monitoring

Residential area monitoring

High campus monitoring

Metro monitoring in a transportation park

4. What type of camera is arranged in the place where the entrance and exit of the station has a strong light and dark contrast?

Low illumination Camera

Laser Camera

Wide Dynamic Camera

Infrared camera

5. The advantages of using video surveillance and electronic patrols together is () (Multiple Choice)

Video surveillance is usually used as evidence afterwards, and patrol inspections because the security guards must go to the prescribed locations to inspect the inspections in time, some hidden dangers can be found in time to eliminate possible incidents in the bud.

The manager’s work of managing the security by querying the video surveillance video is time-consuming and laborious; the electronic patrol system can check the work of the inspectors at a glance.

Video surveillance cannot detect smoke or fog in time or has false alarms or sensor failure. Through patrols, security is in place in time, and hidden dangers can be found in time to prevent accidents.

There is a blind spot in video surveillance, and criminals may perform activities outside the surveillance range. The electronic patrol system can enable patrol personnel to conduct timely inspections of dead corners, thereby greatly reducing the incidence rate of video surveillance dead corners.
