SOLAR TODO delivered a Smart Security System deployment in Puebla, Mexico to protect a large perimeter with fast intrusion response, reliable detection coverage, and continuous operation despite variable local infrastructure conditions.
Answer Capsule: A 483m perimeter was secured with a large 24-zone hybrid alarm, multi-sensor detection, PTZ auto-tracking (<2s), and self-monitored recording—backed by solar + LFP battery + grid for 72hr autonomy.
Project Overview
In Puebla (19.04, -98.21), the client required a perimeter security solution that could handle multiple entry vectors—doors, windows, breakage events, and line-of-sight intrusion—while also reducing investigation time after an alarm. SOLAR TODO designed the system around a large 24-zone security architecture with TCP/IP connectivity and a full detection-to-verification workflow:
intrusion → alarm (<2s) → PTZ auto-track → NVR recording → app notification → dispatch.
The result is a security installation where alarms are not just signaled; they actively trigger real-time camera reorientation and evidence capture within seconds.
Local Infrastructure Challenges in Puebla
Puebla’s mixed urban and peri-urban environments often present three practical constraints for security deployments:
- Power interruptions and unstable supply: Facilities can experience short outages due to network variability and maintenance windows. For a security system, even brief downtime can create unacceptable blind periods.
- Concealed entry paths and fragmented coverage: Perimeters frequently include multiple access points and structural features (doors, glass, walls). Without sensor diversity, an intruder can exploit coverage gaps.
- Investigation latency: When an alarm triggers without automated visual verification, staff must manually search camera feeds. This delays response and can reduce the effectiveness of dispatch.
SOLAR TODO addressed these constraints through a three-source hybrid power approach (Solar PV + LFP battery + grid), a multi-layer sensor map, and a smart linkage that couples detection to camera tracking and recording.
System Design: Perimeter Coverage and Detection Strategy
The installation protects a 483m perimeter with a carefully mapped sensor layout designed to detect both direct intrusion and manipulation attempts.
Alarm Core (24-Zone, TCP/IP)
At the heart of the system is a 1× 64-zone hybrid alarm panel (TCP/IP) operating as the control and event router. Although the client’s deployment is described as a large 24-zone security system, SOLAR TODO configured the panel to support the required zone segmentation for the perimeter and protected areas while leveraging the panel’s 64-zone capacity for future expansion and flexible wiring.
Two LCD touch keypads (2×) provide local control, arming/disarming, and status visibility for operators.
Intrusion Detection: Pet-Immune Motion and Contact Coverage
To reduce false alarms from domestic animals and routine movement, motion detection uses 24× PIR (dual-element, pet immune 25kg). The dual-element approach improves stability against nuisance triggers, while the 25kg pet immunity supports safer operation in environments where animals may roam near protected zones.
For entry-point integrity, SOLAR TODO installed 48× magnetic door contacts, covering gates and door assemblies where tampering or opening would otherwise be difficult to detect reliably.
Glass Break and Environmental Smoke Detection
To address vandalism and forced-entry attempts involving windows and glass surfaces, the system includes 12× glass break sensors (7m range).
For early warning on life-safety hazards, SOLAR TODO added 12× photoelectric smoke detectors. This expands the scope beyond intrusion-only security to include smoke detection as part of the same alarm workflow.
Line-of-Sight Perimeter: Quad IR Beams
For perimeter line-of-sight detection, the system uses 5× quad IR beam (100m range). These beams provide a long-range, structured detection layer that complements PIR and contact sensors—particularly useful along fence lines where motion sensors might be affected by background movement.
Video Subsystem: PTZ Auto-Tracking and Evidence Recording
A key success factor of this deployment is the integration between alarm events and camera behavior.
Fixed Cameras (12× 4MP)
SOLAR TODO installed 12× 4MP HD bullet/dome cameras configured for IR, H.265+ compression, and IP67 weather resistance. This combination supports durable outdoor monitoring across Puebla’s seasonal conditions and provides consistent image quality while reducing storage load via H.265+.
Auto-Tracking PTZ Cameras (2× PTZ 2MP 20x)
To accelerate identification and reduce manual searching, the system includes 2× PTZ 2MP 20x zoom (auto-tracking) cameras. When an intrusion event is detected, the smart linkage triggers PTZ auto-track immediately.
Recording and Storage (16ch NVR + 4TB)
For centralized recording, SOLAR TODO configured 1× 16ch NVR (H.265+, 4TB HDD). The NVR records evidence after the event chain begins, ensuring that the moment of intrusion and subsequent activity are captured for review.
Alarm Output and Alerting
To ensure alarms are unmistakable on-site, the project uses layered siren outputs:
- 5× indoor siren (110dB) for protected interior zones
- 2× outdoor siren/strobe (120dB) for external perimeter presence
The combination of audio and strobe improves deterrence and visibility for guards and nearby occupants.
Hybrid Power Architecture: Solar + LFP Battery + Grid
While solar generation is part of the overall hybrid concept, this project emphasizes the system’s hybrid power reliability for continuous operation.
SOLAR TODO deployed a three-source hybrid power system (Solar PV + LFP battery + grid, advanced) designed for 72hr autonomy. This ensures continuity during grid outages and reduces the risk of downtime during periods when utility supply is interrupted.
The security system remains operational across the full workflow—alarm signaling, PTZ tracking, NVR recording, and app notification—because the power strategy is engineered for sustained availability.
Smart Linkage Workflow (Under 2 Seconds to Visual Verification)
The project’s smart linkage is the differentiator between “alarm-only” and “alarm-with-verification.” SOLAR TODO configured the event chain exactly as follows:
- intrusion is detected by the mapped sensors
- alarm (<2s) is triggered by the alarm panel
- PTZ auto-track immediately reorients to the event area
- NVR recording starts/continues for evidence capture
- app notification alerts authorized users
- dispatch is initiated based on the event and policy rules
This reduces the typical time-to-evidence, helping security personnel focus on confirming and responding rather than searching multiple camera feeds.
Monitoring Mode and Standards Compliance
The installation uses self-monitored operation, meaning the system is managed locally with automated event visibility and alerting.
SOLAR TODO aligned the deployment with internationally recognized security and reliability requirements, including:
- EN 50131 (alarm systems—electronic security systems)
- UL 1023 (burglary alarm units and systems)
These standards support structured alarm performance expectations and help ensure the system’s event behavior is consistent and testable.

Frequently Asked Questions
1) How quickly does the system start camera tracking after an intrusion is detected?
The configured smart linkage triggers PTZ auto-tracking in under 2 seconds after the alarm event is generated.
2) Will pets trigger motion alarms around the protected areas?
The system uses 24× PIR dual-element sensors with pet immunity up to 25kg, designed to reduce nuisance alarms from animals.
3) What happens during a grid outage in Puebla?
The system uses three-source hybrid power (Solar + LFP Battery + Grid) and is designed for 72hr autonomy, maintaining alarm, PTZ tracking, and recording continuity.
4) Does the system record video automatically when an alarm occurs?
Yes. The workflow is configured as intrusion → alarm (<2s) → PTZ auto-track → NVR recording → app notification → dispatch, so evidence capture is part of the event chain.
Conclusion
SOLAR TODO’s Smart Security System deployment in Puebla demonstrates how a perimeter security design can be both comprehensive and operationally efficient.
