4P350V Four-Cylinder Pick 4 Machine with Cameras

The 4P350V is a four-cylinder pick 4 lottery machine with a camera mounted on top of every cylinder. It is built for operators who must prove each drawn ball on record: as each of the four transparent cylinders releases one ball, the camera above that cylinder films it, and the result appears as an underlined digit on the matching front screen, forming a four-digit combination such as 1-2-8-1. This page covers how the machine is built and how the draw, capture and display chain works.

How does the 4P350V verify every drawn ball on camera?

Each of the four cylinders carries its own motor-plus-camera unit on top. When a cylinder completes its draw and one numbered ball is presented, the camera directly above that cylinder captures the ball, so every digit of the pick 4 result is tied to a filmed ball rather than to a software output alone. For operators running public or broadcast draws, this is the core value of the machine: any dispute about a result can be settled against camera records of the four physical balls. The camera verification happens independently per cylinder, so the record for digit position one, two, three and four is always separable. Combined with the transparent cylinders, which let the audience watch the balls mix and drop with nothing hidden inside the housing, the 4P350V gives you a draw that is both visually open and documentarily backed.

How is the four-cylinder mixing section built?

The upper half of the machine is a row of four identical transparent cylinders, each one a self-contained drawing chamber. Inside each cylinder, solid-color balls of 4 cm diameter are kept in motion by the motorized mixing mechanism mounted at the top of the cylinder, the same top unit that carries the camera. Each cylinder is loaded with up to 10 balls, which matches the 0-9 digit range a standard pick 4 game needs per position. Because the four chambers are physically separate, balls can never migrate between digit positions: the ball drawn from cylinder one is definitionally the first digit, and so on. The transparency of the cylinder walls is a structural choice, not decoration — the audience, the presenter and the camera all see the same mixing action, and there is no opaque section where a ball could be concealed. The four cylinder tops are aligned on a shared mounting deck above the screen bank, so the whole drawing section reads as one engineered assembly.

How do the four screens display the pick 4 result?

The front face of the cabinet carries four display screens in a horizontal row, one screen aligned under each cylinder. After the camera unit above a cylinder films the drawn ball, the corresponding screen presents that digit as a large numeral inside a circle with an underline — the underline marks it as a confirmed, camera-verified digit rather than an intermediate animation. Read left to right, the four screens give the complete pick 4 combination, for example 1-2-8-1. Because each screen is dedicated to one digit position, the audience never has to wait for a scrolling readout or guess which digit belongs to which draw; the spatial layout of the screens mirrors the spatial layout of the cylinders. For televised or stage draws, this one-screen-per-cylinder arrangement also gives the production crew a clean, static shot of the final result.

What makes up the cabinet and electrical section?

The lower half of the 4P350V is a light grey / white cabinet that houses the screen bank, the control electronics and the power supply for the four motorized cylinder units. A black horizontal trim panel runs across the lower front of the cabinet, and an LED accent light strip at the base gives the machine stage presence during a live draw — blue is the standard look shown on our floor, with other colors possible on request. Electrically the machine is organized around four parallel drive channels: each cylinder's motor-plus-camera unit is driven and read independently, and the four screen outputs are tied one-to-one to those channels. This parallel structure is what allows the four digit positions to be drawn, filmed and displayed as separate events under one start command. The cabinet form factor is sized to stand alone as a draw station; dimensions and cabinet details can be adapted to your venue when you send us your game format.

How is the machine assembled and tested before shipment?

Assembly brings together the four cylinder sub-assemblies, the screen bank and the cabinet wiring, after which each machine goes through draw-cycle testing in our testing room: repeated mixing and single-ball draws per cylinder, camera capture checks on each top unit, and verification that the filmed digit matches the digit shown on the corresponding front screen. Only after all four channels pass repeated cycles is the machine released for packing. Finished units are packed in export wooden crates marked with fragile and this-way-up labels, built to protect the transparent cylinders and the camera units during sea or air freight. When you request a quote, tell us your game rules and destination port, and we will confirm the configuration, crate dimensions and shipping plan for your order.

Can the 4P350V be configured for different pick 4 games?

Yes. The machine is configured at the factory around your game: ball sets, digit ranges per cylinder and the on-screen result layout are set up according to the pick 4 format you run. Send us your game rules when you inquire and we will prepare the machine to match them. If your venue needs a different overall size or capacity than the standard build, we also build multi-cylinder drawing machines to custom dimensions — tell us your floor space and ball volume requirements and we will propose a layout. This configurability is why the 4P350V is used as a flexible drawing solution for operators whose game formats differ from market to market.
