Question 1

How many cameras does a park or campus need?

Accepted Answer

Perimeter cameras every 50-80 m of fence, one panoramic or PTZ per major plaza or junction, one per gate lane plus one per face terminal, one per elevator car, plus indoor coverage per building. A 20-hectare campus typically lands between 150 and 400 channels; the reference platform capacity is 2,000 channels.

Question 2

Can video, access control and parking run on one platform?

Accepted Answer

Yes - one management platform takes 2,000 video channels, 300 doors, intercom, ANPR and alarms, shares one user directory and one e-map, and cross-links them so a single rule can pop video, lock doors and push to phones. Subsystems should come from the compatible ecosystem to keep the linkage.

Question 3

Does face access work for visitors?

Accepted Answer

Staff enroll once and pass in about 0.2 seconds with liveness detection; visitors pre-register and receive a time-limited face or QR credential, and their plate can be pre-authorized for the parking barrier. Strangers raise a real-time alert and every passage is logged.

Question 4

What does a thermal camera add over normal cameras?

Accepted Answer

It works in zero light and bad weather, reads temperature so it flags overheating before smoke exists, and sees distant fire points across large grounds. It is an early-warning layer, not a certified fire-alarm system, and it cannot recognize faces - pair it with optical cameras.

Question 5

What happens when the fence is crossed at night?

Accepted Answer

Perimeter analytics fire within seconds at the claimed 99 percent accuracy; the five-level alarm engine pops the camera on the video wall, pins the location on the e-map, can trigger sirens and lock adjacent doors, pushes to the duty phone, and a 42x PTZ preset can swing onto the breach point automatically.
