How much of your CCTV coverage can actually identify a face?
An interactive 3D model of a complete IP CCTV system showing real coverage instead of camera symbols on a drawing.
- FOV cones for dome, fisheye, bullet, LPR and PTZ cameras
- DORI zones: identify 250 px/m, recognise 125, observe 62, detect 25
- A 4MP 2.8 mm dome identifies faces only up to about 4 m

What really happens inside a building when a fire starts
An animation of fire and life safety systems responding together, from one smoke detector to Civil Defense notification.
- FACP, notification, smoke control, door release and lift recall
- Sprinkler flow switch, jockey, electric and diesel fire pumps
- Why the C&E matrix, trade coordination and integrated testing matter

Sep 2026 · Checklist
A 5-point checklist for every ELV submittal
For new engineers reviewing their first shop drawings: most submittals fail at the interfaces, not the equipment.
- Architecture vs specification, containment and segregation
- Link lengths measured on the real route, IDF locations
- PoE budget, UPS autonomy and the integration matrix

Temporary power: 10 steps before the first tool spins
Temporary power is where site discipline slips. Ten close-out items before energising anything on a construction site.
- Approved temp power SLD, genset, neutral-earth bond and electrode
- Type-tested ACS boards, 30 mA RCDs, 110 V CTE for hand tools
- Cable selection, overhead clearances, test and tag regime

Fiber backbone submittals: the same three gaps
Lessons from reviewing fiber backbone submittals, with a worked loss budget on an 800 m OS2 link.
- Missing loss budget: 2.42 dB vs a 6.2 dB transceiver budget
- Extra cross-connects can fail a link on paper
- Confined space entry for manholes in the method statement

BMS points, and who starts the smoke fan in a fire
DI, AI, DO and AO explained in two questions, plus the fire interface point checked most often in submittals.
- The FACP drives smoke fans by hardwired relay and overrides the BMS
- Every DO command needs a DI status feedback
- Fans and dampers confirm operation within 60 seconds

Building Management System, explained simply
The closed control loop behind every large building: sense, communicate, decide, act, report.
- Intelligence sits in the DDC controllers, not the server
- The BMS monitors the fire alarm system and never commands it
- Most disappointing BMS projects are commissioning failures
