Physical security as a service (PSaaS) is a label providers use for physical security sold as a subscription or managed service. It is not a formal standard or a fixed bundle: depending on the provider, an offer may include one or more of cloud-managed video, door access control, intrusion alarms, professional monitoring, hardware and lifecycle services such as installation, maintenance and replacement. On-site cameras, readers, locks and sensors stay in your buildings; some or all of the software, storage, monitoring and upkeep is delivered as a service. It overlaps with narrower models such as video surveillance as a service and access control as a service.
At a glance
- PSaaS is a provider label, not a standard; offers may include one or more of cloud video, door access, alarms, monitoring, hardware and lifecycle services.
- On-site hardware remains; depending on the offer, management, updates, event history and maintenance move to the provider.
- Some offers include professional monitoring by live operators; many do not, so the response side varies widely.
- Pricing is usually per camera, per door or per site per month, with hardware bought upfront or folded into the fee depending on the contract.
- You still own camera placement, network design, privacy compliance and code compliance at the door.
What problem it solves
Many organizations end up with a different security vendor at each site: one company’s cameras recording to a box in a closet, another’s badge system on an old server, and a separate alarm company on a phone line. Each has its own login, maintenance contract and failure modes, and nobody has a single view of what is happening across locations. Replacing all of it at once is a large capital project.
PSaaS offers aim to address that by moving some or all of the pieces onto a provider’s platform or managed service, often with integration between them, and spreading the cost over a subscription. A door forced open can be checked against the camera covering it from one screen. Adding or removing a person’s access, pulling video from another city or checking that every camera is online happens centrally. Where monitoring is included, it also gives smaller teams a way to have someone respond to alarms at night without staffing a security desk.
How it works
On-site hardware. IP cameras, card readers, door controllers, locks and sensors are installed at each site, usually by an integrator. They are network devices, so they need cabling, power (often PoE), and a protected network segment as part of IoT security.
Cloud platform. Video management works like video surveillance as a service (VSaaS), with recording on the camera, on a small appliance or in the cloud. Door management works like access control as a service (ACaaS), where controllers in many products keep local permissions so doors keep working through an internet outage; behavior varies by product. Some platforms do both natively; others integrate separate products.
Monitoring and response. Depending on the offer, alarms, door events and video analytics alerts go to your staff, to a provider’s monitoring center, or both. Professionally monitored offers can resemble traditional intrusion alarm and monitoring, with operators verifying events on video before dispatching help.
Add-ons. Common extras include visitor management, intercoms, environmental sensors and longer video retention, each usually priced separately.
When it matters for buyers
- When opening a new office. Starting on one subscription platform avoids adding another recorder, server and alarm contract.
- When legacy systems reach end of life. A failing recorder or unsupported badge server is a natural point to consolidate.
- When standardizing many sites. One platform and one set of credentials across locations is the main draw.
- When nobody responds after hours. Offers that include monitoring can fill that gap, if the contract says who responds and how.
- When comparing capital and operating cost. Subscriptions lower upfront spend but add an ongoing fee; compare total cost over the expected life of the hardware.
Questions to ask vendors
- Which components are included: video, door access, alarm monitoring, visitor management, sensors? Which are separate products or partners?
- Do you provide live monitoring, and if so, what do operators see, what can they do, and how fast must they act?
- Who owns the hardware, and what happens to it and to our video and door history if we cancel?
- Can we reuse our existing cameras, readers or locks?
- What happens at each site if the internet or your platform is down?
- How much upload bandwidth does each site need with our camera count and retention?
- Who installs, maintains and is responsible for code compliance at the door?
How it differs from VSaaS and ACaaS
VSaaS and ACaaS are single-system models: cloud-managed cameras, or cloud-managed doors. PSaaS is a looser provider label for subscription or managed physical security, with no agreed scope: one PSaaS offer may be cloud video with monitoring, another door access plus hardware and maintenance, another several systems together. The terms also overlap in practice, because many VSaaS and ACaaS providers sell or integrate the other half. Judge an offer by what it actually covers, how well the parts work together, and who responds when something happens, not by the label. For help comparing options, see our video surveillance overview.
