This unit comes with a 9800mAH rechargeble battery pack instead of disposable. I am a Paranormal Investigator and the Founder of a team that has been building the Kinect Cameras for a few years. We are however new to selling them on eCRATER. Many Investigators on my team has been using this exact model and has gotten great results. We have sold many Kinect cameras to other Paranormal groups, Paranormal Conventions, Private Individuals, etc.. Before we sell any model, we put the camera to the test. We check for stability. We aim to keep improving our Kinect cameras for the years to come. We want our customers to be happy with their purchase as we are with the Kinect SLS. How the Kinect camera works: It has four major components which are a four-microphone array, IR emitter, Depth camera, an IR camera. The four-Microphone array pinpoints the location of voices/sounds while filtering out any background noises. The IR emitter projects a pattern of infrared lights, and when those lights are distorted, it then is read by the depth camera. The depth camera then analyzes the IR patterns and builds a 3D map of the room, people, and any objects. The IR light is no different than any other device that has them. Your order will include: New Windows tablet 8"-11.6" screen whichever is available at the moment. It will have a 32GB Hard drive. Kinect 360 camera. These are the only thing used since they do not make them any longer. Metal grip handle which can be placed on the table or carried around. A 12V rechargeable battery pack. We have added a connector if you would like to use a backup battery. All you have to do is plug it into the connector. Your Tablet can also be used for several other things when it is not connected to the Kinect SLS camera such as EVP Software, Dual Cameras for Pics/Video, and Audio Recording and More This device is experimental. I do not guarantee you will catch an apparition/ spirit. Our team has had good luck with it, but it's different for everyone. I recommend you document all findings with the unit. We do not accept returns on our Kinect since they are modified. We do give exchange for 30 days on your tablet. After that, it will be covered by manufacturer warranty. If for any reason your Kinect camera needs to be fixed a year from now you can contact us for assistance in this. We do charge a small fee.
