Sketch your connected site.

Start a conversation with a simple equipment plan for your Home, Shop, Office or Factory. No account, server uploads or paid tools.

Your site planner

Everything runs locally in your browser. Editable JSON includes the plan and an embedded copy of any imported floor-plan image. Autosave is off unless you opt in. The interactive editor and calculators require JavaScript.

Concept only, not an installation drawing. Camera cones illustrate direction and a chosen angle, not coverage, detection range or a guaranteed view. A site survey must validate sightlines, obstructions, cable paths, power, compatibility and applicable requirements.

Loading the local editor…

Plan controls

Autosave is off until you opt in. If enabled, plan details and an embedded copy of your floor-plan image (if used) are stored in this browser’s local storage on this device—not sent to HTMS. Anyone with access to this browser profile may see them. Browser storage can be cleared or unavailable; use Download editable project JSON for a separate backup. Turning autosave off removes the saved copy. Clear autosave also removes it.

Templates are illustrative and not to scale. Replacing the background keeps equipment and cables, but clears calibration. Use a flat, top-down plan; perspective images cannot give reliable lengths.

Not calibrated — cable lengths unavailable.

Select a device or cable. Drag devices, or edit their coordinates below. Arrow keys move a selected device; Delete removes a selection.

Local site plan

C = CCTV · W = Wi-Fi · A = Access reader · ! = Alarm · R = Rack. Teal lines = cable routes; translucent camera cones show illustrative direction/FOV only. Gold = selected item. Long labels are shortened here; full labels appear in the checklist.

Coordinates are drawing units, not metres. Use these controls instead of tapping the plan: Place adds a device; Cable adds a bend; Scale marks one endpoint; Select moves the selected device. On the focused plan, arrows move a selected device (Shift for larger steps).

CCTV storage estimate

Constant average bitrate × camera count × recording schedule × retention. Not a recorder capacity or retention guarantee.

Enable JavaScript to calculate.

Decimal TB (1 TB = 10¹² bytes), not usable disk capacity. Audio, VBR peaks, codec, RAID, filesystem overhead and actual motion schedules affect retention. Validate with the recorder and drive specifications.

PoE power budget

Sum of entered watts for devices marked “Powered by PoE”. Racks and alarms start excluded; check every device.

Enable JavaScript to calculate.

This is aggregate power only. Check per-port limits, IEEE PoE class, port count, startup peaks, cable loss, power supplies and manufacturer compatibility separately. No cable category or maximum run is inferred.

Concept only. No coverage, compatibility or retention guarantee. Verify on site before purchasing or installing. Cable lengths need calibration and exclude vertical runs, slack and fittings. All watts are user-entered assumptions.

From a sketch to a site-validated design.

Use editable project JSON to save and reopen the complete plan; it embeds any local background image. PNG, CSV and print/PDF reflect the current plan, cable quantities and camera directions. Do not include sensitive floor plans unless you are authorised to store and share them.

Standalone tools: CCTV storage calculator and PoE budget calculator.

Discuss your requirements with HTMS

Downloads do not send an enquiry or share your plan with HTMS. Contacting HTMS is a separate step.

Privacy and optional usage counts

Optional usage counts

Choose whether to send first-party aggregate tool-action counts. Tool inputs are not included; you can withdraw your choice at any time.

This browser stores your yes/no choice in localStorage, not a cookie. Tool entries are not stored by this analytics feature. Browser Do Not Track and Global Privacy Control override permission. If storage is unavailable, analytics stays off and the error is shown.

Privacy and optional usage counts

Usage counts are off. No choice is required to use the tools.
