Quick answer
What is a mobile surveillance unit?
A mobile surveillance unit is a trailer- or tower-mounted camera system, usually solar powered with its own batteries and cellular connection, placed on a site without permanent cameras or power. Safeguard On Demand puts trained operators behind each unit: alerts are verified on live video, intruders are warned through the tower loudspeaker, and if they stay, a patrol officer or police are dispatched.
Key facts
- Solar and battery powered, cellular connected
- Deploys without power or network hookups
- Live operator verification and voice-down
- Patrol or police dispatch
- Ideal for construction, lots and vacant property
The problem
Some sites cannot have permanent cameras
Construction sites, open lots and vacant properties need protection but have no power, no network and no budget for a guard every night.
No power or network
Temporary sites cannot run wired camera systems.
Guards everywhere are costly
Large open sites would need several guards to cover every angle.
Recordings do not stop theft
Unmonitored cameras only show what was taken.

Choosing coverage
Camera tower, guard or both?
A mobile surveillance unit is the most cost-effective way to watch large, open or temporary sites overnight. A standing guard is better where someone must check people and deliveries; many sites use a guard during the day and towers at night.
For sites with existing cameras, remote video monitoring can use your system instead. Towers pair well with mobile patrol for response and fire watch on construction sites.
California considerations
What California site owners should know
California Penal Code §632 prohibits recording confidential conversations without the consent of all parties, so our towers use audio for live voice-down warnings rather than recording private conversations, and cameras are aimed at areas with no expectation of privacy. Posted signage is recommended.
Where officers respond on site, they must hold BSIS Guard Cards and work for a licensed private patrol operator. Verify any company or officer on the state’s DCA License Search.
