Run the numbers before you ask for a quote

The same rules of thumb our engineers use for a first design. Good enough for budgeting; the final numbers come from a site survey.

Enter kWh from your bill or a device list; get panel size (kWp), inverter, LiFePO4 battery and roof area for on-grid, hybrid and off-grid systems.

Enter cameras, resolution, codec and retention days; get total TB, per-camera bitrate and a drive/RAID layout for the NVR.

Add up servers, switches and NAS to get a UPS rating (VA/W) with 25% headroom and the battery energy to ride through an outage.

Before you renew with your ISP: size download and upload from users, cloud apps, video calls and remote CCTV viewing.

Counts access points two ways, by floor area and by people online at once, for Wi-Fi 6, 6E and 7. The higher number wins.

Add up the PoE draw of cameras, APs and IP phones to get a switch budget with 20% headroom. PTZs that need 802.3bt get flagged.

Send us a floor plan or a few photos of the site

We’ll come back with a few questions, then a first design. The first consultation is free, in Lao, Thai or English, on WhatsApp or our Facebook page.
