Read the passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.
The arrival of 5G recasts surveillance as a truly instantaneous enterprise: ultra-low latency curbs jitter, while higher throughput preserves definition in live feeds. When seconds matter, dispatchers act on crisper, current imagery rather than belated footage. Because endpoints can be authenticated and updated remotely, even legacy cameras are folded into wider patrols. As networks scale, data moves not only faster but also more predictably, so operators coordinate responses across sites, and routine incidents are processed automatically instead of queuing for human review.
In dense estates, the promise of 5G is seamless interoperability: sensors, alarms, drones, and doors converse across one fabric rather than sputtering in silos. If disparate systems are braided into a single pane of control, situational awareness becomes broader and automation more deliberate. Integration also introduces exposure – massively connected estates invite volumetric attacks like DDoS – yet resilient design and throttling can attenuate those shocks. When maintenance is orchestrated centrally, upgrades ripple out quietly, so field teams spend less time firefighting and more time auditing risk.
What accelerates most is inference. Edge models triage streams, while cloud pipelines compare scenes citywide. Instead of pinging guards with every twitch, AI demotes spurious triggers and promotes anomalies that cohere across feeds. These analytics arrive ubiquitous and near-real-time, so patrols shift from reactive rounds to preventative sweeps. Because bandwidth is ample, “heavy” classifiers no longer choke links, and dashboards surface patterns – suspicious clustering, tailgating, unbadged lingerers – before a breach metastasizes. In short, machines shoulder drudgery; humans arbitrate consequences.
Mobility is the hinge. Drones map perimeters, wearables stream body-cam views and vitals, and they hand off feeds to control rooms without stutter. When a fire alarm trips, cameras pivot; medics, police, and facility teams co-view the same telemetry. Where coverage once fractured indoors or in crowds, 5G stitches paths so escorts, evacuations, and cordons are choreographed in one channel. The net effect is faster, more coordinated interventions – provided privacy is respected and cybersecurity stays vigilant.
