Again, go back to page 446 and read what it says about sensor functions, especially the table on the right hand side. Notice how camera s and microphones are listed as sensor functions
In your examples, everything on the list of sensor functions in that table can be chosen as the part of an array or a single sensor after you've gotten the housing. Anything not listed, such as the audio and video enhancements, would have to be bought separately. The camera and omni-directional Mic would each count as one capacity, just like atmosphere sensor and Geiger counter.
I never said the array covers everything you listed. I specifically said it covers sensor functions, which are explicitly listed.
ETA:
Now that I'm in front of a computer, let me get the relevant sections.
Page 445, Sensors:
Sensors need to be placed in a housing or case of some sort, or built into another device.
Sensors are available in seven ratings (2–8) and two types: single and array.
Sensor array: This sensor package includes up to eight functions listed under Sensor Functions.
Single sensor: This is a sensor that can do only one function listed under Sensor Functions
Page 445, Housings:
Sensors can be put into devices that have capacity. Most vehicles and drones come factory-equipped with a sensor array (at a rating listed with their stats). What you can put your sensor in is limited by the Rating of the sensor (see Sensor Housings table).
Page 446, Sensor Functions (emphasis mine):
All of the functions you can choose for your sensor(s) are listed on the Sensor Functions table. If a function has the same name as an imaging or audio device, it’s the same as its description in those sections, with a Capacity equal to its Rating, and thus is not described here.
Page 446, Sensor Housings table
Lists the maximum rating a housing can hold, greater size = higher rating
Page 446, Sensors
Lists price for handheld housings (capacity 1 through 3) and wall mounted housings (capacity 1 through 6). Also lists price for array and single sensors, which take up 6 and 1 capacity respectively.
Page 446, Sensor Functions
Lists all 13 sensor functions which a sensor can perform. Notice that several of these are not listed on page 446 because they are audio or video devices. These include: Camera, Directional Microphone, Laser Microphone, and Omni-Directional Microphone.
So in your example, you pay the following:
Rating 3 Sensor Array, 3000¥
1. Omni-directional microphone (sensor function, Rating 3, included with array), Spatial Recognizer (1000¥, 2 capacity as per page 445), and Select Sound Filter Rating 1 (250¥, 1 capacity). This fills all the available capacity of the microphone
2. Camera (sensor function, Rating 3, included with array, Thermographic Vision (500¥, 1 capacity as per page 444), Low-Light Vision (500¥, 1 capacity), and Flare Compensation (250¥, 1 capacity). This fills all available capacity of the Rating 3 camera
3. Atmosphere Sensor, Geiger Counter, Laser Range Finder (each 1 capacity, included with array).
This would leave you with 5 out of 8 capacity used, for a total cost of 5500¥. You can certainly add 8 rating 3 cameras to a sensor array, but since facing isn't well implemented in Shadowrun it wouldn't really do you much good in my opinion. You don't even technically need a microphone unless you specifically want enhancements for it, as the camera itself has a microphone as per page 443.
