A multifamily community installs a controlled-access garage. Fobs are issued, the gate works, the system logs every legitimate entry. On paper the garage is secure.

Then two people walk in behind a resident’s car and the entire investment is bypassed in four seconds.

This is tailgating, and it is the most common way controlled-access parking gets breached. It requires no tools, no skill and no forced entry. It requires only patience and a gate that takes eight seconds to close.

Why access control cannot solve this by itself

Access control is built to answer one question: is this credential valid? It answers it well. What it cannot do is count people.

The gate opens for an authorised resident. Everything that follows the resident through the opening is invisible to the system. The access log will show one clean, legitimate entry — which is exactly what makes tailgating so difficult to catch after the fact. The log is not wrong. It is simply answering a different question from the one you care about.

Anti-tailgating hardware exists — turnstiles, mantraps, vehicle-detection loops — but on a residential garage it is usually impractical, expensive, and unpopular with the residents who have to use it every day.

Why recordings do not solve it either

A camera on the gate captures the tailgate perfectly. You can watch it happen, in good detail, the following morning.

By then the people are gone and so, frequently, are catalytic converters, bicycles, tools, packages, or the contents of several unlocked vehicles. You have excellent footage of an event you did not prevent.

Worse, the resident who held the gate open — often out of simple politeness — has no idea anything happened. There is no feedback loop. The same courtesy will be extended tomorrow.

What live monitoring does differently

In the clip above, two intruders tailgate into an apartment garage. An Overwatch agent watching the live feed sees them enter behind an authorised vehicle and identifies immediately that they do not belong — on foot, following a car, no fob presented.

The agent issues a two-way voice-down. Specific, immediate, addressed to them. Both subjects leave, and the agent confirms the property secure.

Total elapsed time: less than a minute. Nothing was taken. No resident had to discover anything in the morning. No police report needed writing.

The reason this works is that an agent is not asking “is this credential valid.” An agent is asking “does this person belong here,” which is a question a human answers correctly in about two seconds and an access control system cannot answer at all.

The context most garages are missing

A parking structure is the highest-risk area of most multifamily properties, and it is the area residents think about most. It is enclosed, poorly lit in sections, full of valuable property, and entered at hours when nobody else is around.

It is also where residents form their opinion about whether a community is safe. A resident who has had a vehicle broken into in their own garage rarely renews. The cost of a single tailgating incident is not the stolen property — it is the turnover that follows, and the reviews that mention it.

What to do about it

A few things help before anyone spends money on monitoring:

  • Time your gate. Most gates stay open far longer than they need to. Shortening the cycle removes the easiest opportunity.
  • Look at what the camera on the gate can see. If it is pointed at the gate rather than at the approach, an agent or a reviewer has no warning and no faces.
  • Tell residents plainly what tailgating is. Most people who hold a gate open are being polite, not careless. They usually stop once they understand the mechanism.

Then add the piece that hardware cannot supply: somebody watching who can speak.

Protect the garage, not just the gate

Overwatch Technologies provides proactive video monitoring for multifamily communities and commercial properties nationwide. Our live agents watch garages, perimeters and amenity areas in real time and intervene while an incident is still preventable.
