No grid, no network, nobody on site. Solar towers with their own wireless connection and ACS operators watching live — for empty buildings, lots between tenants and seasonal sites.
Arson is the one line on Canada's property list that did not fall with the rest — and the American fire services have measured what an empty building does when it burns.

vacant residential building fires were reported to U.S. fire departments each year, causing an estimated 75 deaths and $785 million in property loss annually. The leading cause, at 34%: intentional.

arson offences recorded at abandoned and condemned structures by NIBRS-reporting agencies in 2025, among 6,572 property offences at those locations.

NFPA has separately reported that vacant-building fires were 6% of U.S. structure fires but 13% of firefighter injuries.
There is nothing on the site to build on — no power, no network, nobody. So the coverage brings its own. This is what an ACS tower does in its first night on an empty property.
An ACS tower on empty ground — its own power, its own connection, and nothing on the site it needs to plug into.
The reason empty property goes unwatched is never that nobody wanted to watch it. It is that watching it meant a utility connection, a service account and a trench across ground that is about to be sold.
Solar and onboard storage run the cameras, the lighting and the radio. Nothing is drawn from a meter that was disconnected when the last tenant left, and nothing has to be reconnected to start.
The link out is cellular. There is no line to install, no account to open with a provider, and no cable for anyone to cut at the pole.
Footage is written on board as well as sent. A weak signal or a cell outage costs live monitoring for that period — it does not cost you the recording of what happened.
The same unit covers the north corner this month and the gate next month. A site that is about to change hands, be demolished or be re-let does not deserve permanent infrastructure, and does not need it.
When the property sells or the tenant takes possession, the tower is towed away. There is nothing to decommission, nothing left in the ground, and no contract attached to a building somebody else now owns.
There is no grid, no network and nobody to call from the site itself. Here is what ACS puts where, and what each position is there to stop.
Solar power and a wireless connection on a 25-ft mast, so a building with nothing switched on still gets watched.
An operator speaks to whoever is on the site, over the tower, and escalates from there.
Mobile Patrol & Alarm Response
A licensed officer checks the building on a schedule and attends an alarm, and records what was found each time.
Fixed cameras for the point where the property is re-occupied, re-let or handed to a contractor.
Towers relocate as the property's status changes: between tenants, mid-redevelopment, or at the end of a season — see what an assessment covers
Vacant property is not worth a permanent installation, and does not need one. Everything below arrives on a trailer and leaves on the same trailer.
It arrives behind a truck. There is no service connection to arrange, no permit for a pole, and nothing to leave behind when the property sells.
Its own power and its own link out. That is the whole reason empty ground can be watched properly instead of driven past twice a week.
Fixed views holding the whole site with a zoom head for the approach track and the openings. On empty ground there is no innocent traffic to filter out, so every zone stays armed.

Problem: a temporary site with no power, no network and no time to build out a system.
Plan: a self-powered mobile defense tower with wireless connectivity and live oversight.
Outcome: the tower was live the same week and repositioned as the site changed.
Read the case
Problem: a person detected on a monitored site, well after close.
Plan: AI detection verified by a trained operator, then a live voice-down over site audio.
Outcome: the subject left the property, and the incident report was filed before morning.
Read the caseNo. The towers are solar-powered with a 4-day runtime on a full charge and run on 5G wireless internet, so they don't need grid power or a site network. They're also direct-power capable where a feed is available.
Timing is confirmed at the site assessment. Towers need no permanent install, and we confirm placement against the property's layout and risk windows before we deploy.
Both. Live monitoring is available on every unit. Trained operators verify alerts in real time, intervene by on-site audio and coordinate with law enforcement. Recording is not the same as preventing.
Yes. Mobile patrol sends a licensed officer on scheduled rounds to check doors, gates and the perimeter, and an officer attends when an alarm trips. Every visit closes with a timestamped report.
Yes. There's no permanent install, so towers relocate as the property's status changes: across the site, or to the next property between tenants or seasons.
From tighter urban lots to larger properties and broader perimeters, mobile defense towers scale to the site. Mobile patrols can add scheduled door and perimeter checks.
Yes. ACS operates under Ontario's PSISA and carries comprehensive general liability coverage on every contract.
