To choose a security company in San Lorenzo, first check that it's licensed by Paraguay's National Police, then compare what it actually delivers: equipment, monitoring, response time and who can access your cameras. For most homes, a monitored alarm plus a few well-placed cameras does more than a full-time guard, especially when combined with your neighbours' own organisation.
Alarm, cameras or a guard?
- Monitored alarm: sensors on doors and windows connected to a control centre that alerts and calls you when it's triggered. This is the most common setup for houses.
- Cameras: good for seeing what happens and keeping a record. On their own they don't stop a break-in; they work best alongside an alarm.
- Security guard: makes sense for shops, buildings, gated communities or events. If you hire one, the guard must hold the credential issued by the police.
- Equipment only, no monitoring: cheaper each month, but when the alarm goes off the response depends on you and your neighbours.
First: make sure the company is licensed
In Paraguay, private security companies are regulated by the National Police through its private security oversight department (ABC, 2023 (opens in a new tab)). That department licenses agencies, issues guard credentials and enforces Law No. 5424/2015 (opens in a new tab) (Hoy, 2022 (opens in a new tab)). Every company needs a licensing resolution from the Police Command, and the requirements include being a registered commercial company, having its own premises and life insurance for its guards (La Nación, 2023 (opens in a new tab)).
This matters: in 2023 the police had 135 companies registered nationwide, after cancelling or suspending around 200 in a clean-up (La Nación, 2023 (opens in a new tab)). With an informal company there's no guarantee staff are trained or that your data is protected, access to your cameras may end up with an outside technician, and no one can promise the alarm will respond to a forced entry (Hoy, 2022 (opens in a new tab)).
Ask the company for its licensing resolution number and, if in doubt, check with the National Police before signing.
What's different about San Lorenzo
San Lorenzo is Paraguay's fifth most populous city, with 225,395 residents in 54 neighbourhoods, and about 850,000 people come and go every day; the commercial centre sits on Route PY02 around km 15, and the UNA university campus keeps traffic constant (Wikipedia (opens in a new tab)). That affects response time: ask where the patrol or technician is based and how long it takes to reach your neighbourhood at rush hour.
Residents' experience is telling too. In the San Felipe neighbourhood in 2024, one resident said intruders kept getting in at any hour despite cameras, alarms and dogs (Última Hora, 2024 (opens in a new tab)). In May 2026, in another part of the city, a neighbourhood alarm made two armed motorbike robbers back off (Última Hora, 2026 (opens in a new tab)). The lesson: your home system works better alongside a neighbours' group, a shared neighbourhood alarm or the local security committee, if there is one.
How to compare quotes
Paraguay's consumer protection law, Ley 1334/98 (opens in a new tab), requires a service provider to tell you, among other things, what the service includes, the equipment used, the price including taxes and payment terms, how long the quote is valid and the scope of any warranty (art. 15). Any warranty must be in writing (art. 11). Ask two companies for:
- The same list of zones: doors, windows, yard, gate, garage.
- Equipment and monitoring priced separately: installation cost, monthly fee, and whether the equipment is yours or on loan.
- What happens when the alarm goes off: who they call, in what order, and whether they send someone or just notify you.
- Contract length and the cost of cancelling early.
- A written warranty on equipment and installation.
Before you pay for installation
- Test every sensor, the siren and the phone alerts with the technician.
- Change the camera and app passwords, and ask who else has access.
- Write down the control centre's number and 911 on paper, in case your phone isn't working.
- Get a legal invoice and the signed contract, including the company's licence number.
FAQ
How do I know a security company in Paraguay is licensed?
Licences are granted by the National Police through a resolution from the Police Command. Ask the company for that resolution number and, if in doubt, check with the police before signing.
What's the best security company in Paraguay?
The best one for you is licensed by the National Police, covers your neighbourhood, responds quickly and puts the service and warranty in writing. Compare at least two quotes for the same list of zones.
Do I need monitoring or is buying the alarm enough?
Without monitoring, the response when the alarm goes off depends on you and your neighbours. With monitoring, a control centre alerts and calls you; ask exactly what they do and how fast.
Are cameras enough to prevent break-ins in San Lorenzo?
Not on their own. Residents of San Felipe said intruders kept getting in despite cameras, alarms and dogs; they work best with a monitored alarm and neighbourhood organisation.
