1. Guardian Mode
“Guardian Mode” refers to the capability of mobile security trailers to automatically detect and track individuals and vehicles, while also capturing detailed images around the clock. This seamless operation means you’ll have the evidence you need, even overnight or when no physical camera operator is present.
Flock’s Guardian mode unlocks 24/7 security coverage for your premises while also obtaining actionable evidence in the event of an incident taking place. Movements from people and vehicles are automatically tracked, allowing for zooming in for identifying details during investigations.
This functionality reduces the need for multiple cameras, security guards, and additional labor-hours needed to monitor video feeds.

Watch the video below to see Guardian Mode in action and its ability to zoom in on a suspect exiting one car, stealing an item from another, and returning to his vehicle. Every detail is captured, providing invaluable evidence for investigators.
2. Alert Response Service
Flock’s third-party Alert Response Service instantly connects you with trained professionals who manage after-hours video alerts and can help de-escalate incidents using talk-down speakers and/or directly notify your security team or law enforcement of active crimes as they’re taking place - ensuring rapid and effective responses.
The three major benefits of Flock’s Alert Response Service are:
- Cost-Effective Solution: Get after-hours protection at a fraction of the cost of a full-time guard. Gain access to an entire team of security experts for less than the price of one employee’s salary.
- Proactive Crime Deterrence: After-hours agents respond to Flock video alerts in real-time, using talk-down speakers to deter criminal activity. If necessary, they seamlessly escalate the situation to on-site security or law enforcement, ensuring swift and effective action.
- Peace of Mind for Customers and Staff: Safeguard your customers and staff by proactively de-escalating threats. With trained operators responding to after-hours alerts, you gain unmatched peace of mind and a secure environment around the clock.
3. Talk Down Speaker
Flock’s mobile security trailers are equipped with talk-down speakers that enable your security team to deliver both live and pre-recorded warnings to trespassers. Whenever mobile security trailers detect suspicious activity from an individual or vehicle, talk-down speakers allow you to respond swiftly by issuing direct warnings to trespassers on your premises.
Here’s how it works:
At a construction site, a Flock Mobile Security Trailer detects an unauthorized vehicle. An operator receives the alert via Flock software and uses the talk-down speaker to broadcast a warning message: “You are trespassing. Leave immediately, or law enforcement will be notified.” Startled, the suspects flee before causing any damage or theft.
4. Blue Flashing Lights
Flock mobile security trailers feature flashing blue lights to complement their bold design to send a clear message to potential offenders: that they’re being watched.
Flashing blue lights are the perfect deterrence because:
- Association with Law Enforcement: Blue lights are widely recognized as a symbol of police presence. When offenders see flashing blue lights, they often assume law enforcement or other crime deterrents are nearby.
- High Visibility at Night: Flashing blue lights are bright and easily seen from a distance, especially in dark or low-visibility environments like parking lots, warehouses, construction sites, and more. This visual presence increases the perceived risk of being caught.
5. Integrations with License Plate Readers
Flock mobile security trailers can also integrate with Flock’s license plate readers to deliver unparalleled crime deterrence (mobile security trailers) and actionable intelligence (license plate readers) in the event of an incident taking place.
Integrating license plate readers with mobile security trailers enables businesses to link vehicle data to video evidence, providing the actionable intelligence needed for your security teams and/or law enforcement to expedite case closure.
By integrating license plate readers with mobile security trailers, you’ll benefit from:
- Greater visibility into incidents
- Reduced response times
- Being able to access stronger evidence
