The Prism comes packaged with a wide variety of mounts to fit the needs of installing the Prism onto a helmet or a motorcycle. Here is a description of each of the mounts to use with a helmet or a motorcycle along with an example of how each of the mounts for the Prism can be used.

 

Helmet Mounts

 

Helmet Clamp Kit

Prism_Helmet_Clamp_Mount.jpg

 

The Helmet Clamp Kit enables you to mount the Prism on the side of a helmet. The Helmet Clamp Kit uses a Screw Lock which you can loosen to insert the Support Plate which is what holds the Prism onto the Helmet Clamp Kit. Provided in the package is a rubber pad for placing in-between the Helmet Clamp Kit so that the clamp kit presses against the side of the helmet as much as possible. This is necessary for helmets that are designed with a non-flat surface around the rim of the helmet.

*The Waterproof case cannot be used with the Helmet Clamp Kit.

Glued Surface Mounting Adapter

The Glued Surface Mounting Adapter enables you to mount the Prism on the side of a helmet using the Support Plate without using the Helmet Clamp Kit. This is an alternative to the Helmet Clamp Kit.

*The Waterproof case cannot be used with the Glued Surface Adhesive Mount.

Helmet Surface Mount

Prism_Helmet_Surface_Mount.jpg

The Helmet Surface Mount enables you to mount the camera on any surface of the helmet. You can adjust the camera angle by rotating the joints. When you are not using the camera, unscrew the camera from the pivot. The Helmet Surface Mount requires the Curved Glued Surface Mounting Adapter.

 

An example of using the Helmet Surface Mount on a motorcycle helmet:

Goggle Mount

The Google Mount enables you to mount the camera on the goggle band. This is useful when you wear a helmet and a goggle separately.

*The Waterproof case cannot be used with the Google Mount if you use the Screw Lock and the Support Plate.

Motorcycle Mounts

 

*Note: When using any of the motorcycle mounts, use the QRM wire to tie the Prism and mount to the motorcycle to prevent losing the camera and the mount while riding on the road.

 

Top Surface Adhesive Mount

Top_Surface_Mount1-500x362.jpg

The QRM Top Surface Mount enables you to mount your camera on a flat or curved surface such as windshield, gas tank or a helmet. You can adjust the camera angle by rotating the ball joint on the QRM body. When you are not using the camera, you can simply separate the camera-attached QRM head from the QRM body. The Top Surface Adhesive Mount requires either the Curved Glued Surface Mounting Adapter or the Flat Surface Glued Surface Mounting Adapter.

 

An example of using the Top Surface Adhesive Mount on a motorcycle:

Handlebar Mount

Handlebar_Mount.jpg

The QRM Handlebar Mount enables you to mount the camera on your motorcycle’s handlebar (between 7/8’’ and 1 1/2’’ diameter). You can choose the directions of the mounting arm and the U-bolt to best fit the mount on your handlebar. When you are not using the camera, you can take out the camera-attached QRM head from the QRM body.

 

An example of using the Handlebar Mount on a motorcycle:

Dual Suction Cup Mount

Suction_Cup_Mount.jpg

The QRM Dual Suction Cup Mount enables you to mount the camera on surfaces that require some height for recording such as windshield, gas tank, and trunk. You can adjust the camera angle by rotating the wheel joints or the ball joints on the legs. When you are not using the camera, you can simply take out the camera-attached QRM head from the QRM body. The Suction Cup Covers are included in the package for protecting the adhesive of the suction cups when you do not have Dual Suction Cup Mount attached to a surface. 

 

An example of using the Dual Suction Cup Mount on a motorcycle:

Prism_Mounts-56.jpg

 

 

 

Single Suction Cup Mount

QRM Single Suction Cup Mount can be installed on any relatively flat surface on a motorcycle. You can simply adjust the angle to make the view that you want. You can use the short leg that comes packaged with the Prism and one of the two suction cups to make the Single Suction Cup Mount.

 

An example of using the Single Suction Cup Mount on a motorcycle:

Prism_Mounts-21.jpg

The 2 black disks that are included in the packaging for the Prism in the lower left of the image above are for maintaining the adhesive of the suctions when they are not attached to a surface. When the white pieces of paper are removed from the suction cups after using them for the first time then you will need to use the black disks to maintaining the adhesive so that they will continue to firmly attach to a surface for each subsequent use of the Suction Cup mount.

If the rubber on the Suction Cup mounts become hard due to freezing temperatures in the environment then do not try to remove the suction cups as they have become brittle and will break apart if they are removed from the surface. Give time to allow the rubber to thaw in a warmer environment before removing the suction cups to prevent the rubber from breaking apart.

The QRM head can also be used with the Waterproof Case that comes with the Sena Prism.

 

The QRM Handlebar Mount enables you to mount the camera on your motorcycle’s handlebar (between 7/8’’ and 1 1/2’’ diameter). You can choose the directions of the mounting arm and the U-bolt to best fit the mount on your handlebar. When you are not using the camera, you can take out the camera-attached QRM head from the QRM body.

 

The Handlebar Mount can be mounted on locations such as: The Handlebar, The Engine guard, The Frame guard, or a different location of your choosing.

 

The QRM Top Surface Mount enables you to mount your camera on a flat or curved surface. You can adjust the camera angle by rotating the ball joint on the QRM body. When you are not using the camera, you can simply separate the camera-attached QRM head from the QRM body.

 

The Top Surface Mount can be mounted on flat or curves surfaces such as: The Top Case, The Pannier Case, The Front Fender, or a different location or your choosing.

 

The QRM Suction Cup Mount enables you to mount the camera on surfaces that require some height for recording. You can adjust the camera angle by rotating the wheel joints or the ball joints on the legs. When you are not using the camera, you can simply take out the camera-attached QRM head from the QRM body. The QRM Suction Mount is interchangeable between using two suction cups or a single suction cup.

 

The Dual Suction Cup Mount or the Single Suction Cup Mount can be mounted on: The Pannier Case (Side Case), The Top Case, The Windshield, or a different location of your choice.

 

Note: When installing the Prism to a motorcycle, use the QRM wire to tie the QRM system to the motorcycle to protect it from any accidental falling.

Unfortunately, listening to music and recording audio from a headset is not possible because of the Prism having a higher priority than stereo music (A2DP).

It takes about 3.5 hours to completely charge the battery on the Prism. The Prism comes packaged with a micro-USB cable for charging the battery and updating the firmware. In addition, the micro-USB cable can be used to charge the battery of the Prism while the back door is closed by uncovering the charging port and inserting the cable into the micro-USB port.

Yes. The battery can be removed after unlocking the back door and moving the spring-loaded lock that holds in the battery. Additional batteries for the Prism can be purchased on our online store here: http://www.buysena.com/camera-audio-pack/prism/sca-a0102.html.

Here are the recommended audio settings on the Prism:

 

Bluetooth Audio - On

Internal Microphone Gain - High

Ultra HD Audio Mode - On

Internal Microphone Auto Mute - On

 

Sena recommends to have the Bluetooth Audio Recording feature turned “On”, the internal microphone gain set to “High” and the Internal Microphone Auto Mute turned “On”. With this configuration, whenever a Bluetooth headset is connected to the Prism for recording audio from the headset’s microphone then the internal microphone on the Prism will automatically be disabled. If a person does not want to record audio from a Bluetooth headset then Prism will record outside audio through the internal microphone because the internal microphone gain is set to “High”.
