Plot plan
Boundary from the cadastre, a satellite map or a survey — in real metres
The boundary, the fence with the gate and wicket, the house with its doors, sheds and trees — or open a plan you already have. They are what blocks the view.
Open the CCTV section → Coverage and press «Cover entrances and perimeter»: cameras on the gates, a doorbell at the front door, corner cameras, a recorder and cables. What is already covered stays.
Check the red hatched blind spots, move and turn cameras, change lenses and look through each of them in 3D until every entrance has its ✓.
Export the camera plan, the CCTV schedule with every camera and the estimate to PDF — for the installer and the shop.
A camera sees less than its angle suggests. Walls and the house cast a full shadow, a solid fence or a hedge lower than the camera only a short one — a person’s head shows above it further away. Under the camera there is a blind spot. gardmi computes all of it on your plan and hatches in red what no camera sees.
The camera hangs inside the plot on the fence 3–6 m from the gate and looks along the fence at it: faces of everyone who comes in are large, the street stays out of the picture.
A video doorbell sees the visitor face on at 1.4 m; other doors to the garden and the terrace need only to be watched — a corner camera usually already covers them.
Corner cameras look along the walls: the edge of the picture runs along the facade, so a person walking by the house cannot slip past, and the view stays inside the plot.
The whole view is drawn, past the fence too: watch the road to read number plates or keep an eye on your other plot. When a camera would recognise the faces of neighbours or passers-by, gardmi warns — turn or move it, or note a privacy mask for the recorder.
What matters is not the angle but the pixels on the target. By IEC 62676-4 a face is identified at 250 pixels per metre, recognised at 125, a person is observed at 62.5 and detected at 25. gardmi turns the resolution, the lens, the height and the tilt of the camera into four zones on the plan and names the distances.
Enter the distance at which a face must be identified — gardmi picks the lens. For a 4 MP camera at 2.5 m: 2.8 mm (103°) identifies up to about 4 m, 4 mm (84°) up to 5.6 m, 6 mm (54°) up to 10 m.
The higher the camera, the larger the blind spot below it and the further the face zone starts. The tilt is set automatically — the horizon near the top of the picture — or by hand.
IEC/EN 62676-4:2014 by default; the Russian set follows R 78.36.002-2010 (identification — 120 % of the screen height) and GOST R 51558-2014; the stricter IEC 62676-4:2025 is also there.
The handle at the nose turns the camera within its bracket — it cannot look into the wall; the handles at the edges of the sector change the lens.
Click the camera button in the toolbar and look through the nearest camera: the picture has its real angle, tilt and frame shape, and the arrows switch between the cameras of the project. Drag to turn the camera on its bracket, scroll to zoom a varifocal or PTZ lens — the plan updates at once.
The stream of every camera follows its resolution, the codec (H.264, H.265, H.265+) and the frame rate; days of archive and continuous or motion recording give the terabytes, and gardmi picks the disks for the bays of the recorder with a reserve.
The recorder is chosen for the number of cameras — 4, 8, 16 or 32 channels — with the incoming stream and the PoE power budget checked.
Every PoE camera gets its own twisted pair to a port of the recorder or a switch: the length is the route plus the drops, and a line longer than 90 m is flagged — Ethernet carries power and video up to 100 m.
Where there is no cable and no Wi-Fi, a 4G camera with a solar panel stands on its own post and records to a memory card — it is in the same catalogue and draws the same zones.
You are already in the app — gardmi is installed.
Yes. gardmi installs straight from the browser, without App Store or Google Play: on Android and in Chrome or Edge on a computer press “Install the app”, on iPhone open the site in Safari and choose Share → Add to Home Screen. The app opens full-screen from its icon and keeps the same cloud projects.
Usually four to eight: one inside the plot at every gate and wicket, a video doorbell at the front door and a camera on the corners of the house looking along the facades. Buildings, sheds and tall trees leave blind spots behind them — gardmi hatches them in red, so you add cameras until the plot is covered, not by a rule of thumb.
At gates and doors — 2.3–2.8 m: out of reach, yet low enough to see a face at no more than 15° from above; higher, the camera sees the top of the head. Cameras under the eaves at 3–4 m watch the approaches and the yard. gardmi shows the blind spot under every camera and how far the face zone starts and ends.
It is a trade between angle and detail. For a 4 MP camera at 2.5 m, a 2.8 mm lens (about 103°) identifies a face only up to about 4 m, 4 mm (84°) — up to 5.6 m, 6 mm (54°) — up to 10 m (IEC 62676-4, 250 pixels per metre). A wide lens watches the yard, a narrow one — a gate far away. gardmi picks the lens for the distance you need.
Archive = the streams of all cameras × the recording time. A 4 MP camera in H.265 at 15 frames per second streams about 2.5 Mbit/s, so eight cameras recording around the clock for 30 days need about 6.5 TB — one 8 TB disk; recording on motion only cuts it to about 2 TB. gardmi sums your cameras and picks the disks for the recorder.
Seeing the road — for example to read number plates — is fine, but keep the faces of neighbours and passers-by unrecognisable. In the EU a home camera that films the street or a neighbour’s plot is no longer a purely household matter and falls under the GDPR (CJEU, case C-212/13 Ryneš); in Russia filming the private life of neighbours may breach Article 152.2 of the Civil Code. gardmi draws the whole view, past the fence too, and warns when a camera would recognise people outside your land — then turn or move it, or mask that area in the recorder.

gardmi is a free online planner. Coverage, distances and disk sizes here are a preliminary design — check the final camera positions on site with the real cameras and follow the privacy law of your country.
