The GS1 Laser Grid keeps things straightforward: project a pattern, set up your camera and watch what changes. It suits investigators who want clear visual reference points without adding a set of onboard sensor displays to the session.

A line grid for visual monitoring

GhostStop specifies a red 20 × 20 grid with a central alignment dot. An object passing through the projected light can interrupt or distort the pattern. Reviewing that change alongside your footage is more useful than trying to remember what a dark room looked like a few minutes earlier.

This is a projector for observation. Do not expect it to identify a ghost, explain the cause of a shadow or automatically turn a recording into a 3D model.

Power and practical details

• Power: two AA batteries, not included.
• Dimensions: 4.5 × 3.24 × 1 inches.
• Manufacturer-rated brightness: optimal for roughly 3–4 hours, with visibility beyond six hours.
• Tripod: optional and sold separately.

Battery condition and your viewing setup affect what you can record, so check the pattern through your camera before the session begins. The protective boot shown in the illustration is listed by GhostStop as a while-supplies-last inclusion; confirm it when ordering.

Is the GS1 the right choice?

It makes sense if a visible grid is the main feature you need. For onboard measurements and event tracking, compare the GS2 Laser Grid System. For a compact green-dot option, browse our laser grids.

A simple recording routine

Set the projector on a stable support and keep the camera fixed. Record the empty scene, then make a known movement through it. Use that clip as a comparison and note any later movement by team members. A shifted projector can change the whole pattern, so check the setup before interpreting a disruption.

Follow GhostStop’s indoor-use instructions and product warnings. Avoid eye exposure and reflective surfaces; never aim the laser at people, animals, vehicles or aircraft.
