System Setup

Whether you're a solo-shooter on the street, a B-unit filling in scenes, or location shooting a critical action shot with your lead, Andra is designed to keep up on location and in moving situations with sub-centimeter accuracy. 

Our mobile system options: 

One Ambit System

Typically attached to a camera rig, our 1-ambit system features a 16’ diameter performance area that goes wherever the camera goes. 

Two Ambit System

Using a grid pole with two ambits attached, and operated in a similar fashion to a boom mic, the 2-Ambit system features a moving 16’x 24’ performance area that can go anywhere – just keep the camera and subjects within the performance area.

Ideal uses


Whether you are walking down a street together or sitting beside each other, Andra Radius is perfect for capturing the back and forth between the interviewer and subject, almost instantaneously pulling back to your subject to get that key emotion up close and in low Depth of Field. Put a 2-ambit system with grid-pole on a c-stand, or if your performance area is small enough, you can even hide a single ambit in a piece of furniture. 

To keep your subject feeling more natural and comfortable, for a better result, you can shoot with a much smaller lighting package, just open up your aperture safe in the knowledge your focus will never miss. Intimate moments are closer than ever. 


With an ambit on the camera rig, and your reporter set up with a pack and sensor along side their mic kit, you don’t need to expand your crew to get a live feed with more drama and more natural lighting. Extreme weather reporting may never be the same. Of course, add a pack and sensor and you’re field ready for a one-on-one interview. Pulitzer anyone?


Action shots are unpredictable and challenge even the most hardened focus puller, but with a dolly/steadicam and choreography designed to keep the action in the performance area, the role can change from trying to just keep focus to deciding where it should be. Whether it’s a chase scene, a close-up quick movement, or capturing an extreme sport, when you can stay close, Andra will be right there with you keeping things sharp. New heights of artistic expression and on-screen tension are ripe for the taking.

System Components


The Andra Radius System maintains focus on objects and subjects by tracking their position within a magnetic field. This field is produced by a cube shaped device known as an Ambit.

Rubberized corners, a lip and groove seal and an internal cradle have been engineered to protect the component from normal production use.


  • Creates an 8’ (2.44m) radius magnetic field.
  • Lemo push/pull power connector.
  • No line of sight needed.
  • Up to 25, in a 5x5 grid, can be used at a time to create a maximum performance area of 48’ x 48’ (14.63m x 14.63m)
  • Flexible grid creation to map out the needed performance area.
  • Up to 100 selectable frequencies, within four channel, allowing up to 4 systems to be used in proximity.


  • Mounts to a camera, carried on a boom pole or ambit grid pole, hung overhead or hidden in or behind objects.
  • Dimensions: 11 cm (4.33”) L x 11.19 cm (4.41”) W x 11.19 cm (4.41”) H.
  • Weight: 400g (.88lbs) without mounting plates.
