Instruction: Answer the given question by extracting information from the supporting document.

Input:
Question: Does it have a light indicator, when its in recording mode? Or does it make noises, when battery is low? (Many cams have these oxymoronic feature)
Document: It can also use a combination of those modes. All but the vibration activation mode constitutes continuous operation which is about 10 hours of use I get from a full battery charge. The vibration activation mode can be left on for up to several weeks depending on how often the camera triggers. I wish the motion activation was more like the game trail cameras with a separate motion sensor. That way it could be used for longer periods in that mode without draining the battery.
The new firmware now has my Z16 recording for 2 minutes minimum after the last triggered event rather than the previous 5 minutes as reported in my review. I still wish the duration was user selectable but this firmware update is enough of an improvement for me to change my rating from 3 to 4 stars.
2 weeks or more)~ Excellent field of view. Looks like about 180 degrees without the major 'fisheye' look from most lenses of this type.CON's:~ Price is a little steep but remember, you get what you pay for. (With that in mind, a steal of a deal)~ Not too many con's here...~ Oh, the slightly raised lense might get scratched if putting in a closed space. Be wary.
The video quality degrades significantly in indoor lighting though it is still useful. The 160 degree view is very wide and I would imagine cover most any room. There is some distortion as would be expected from such a wide viewing angle.Recorded sound quality is much better than I expected though be aware of the potential legal consequences if you record someone on audio without their consent.
The time it records for each trigger event is not user selectable and cannot be changed. I'd like to see the option to change that in the widget because less than a minute would suite my needs and result in smaller saved video files so more events could be stored on the memory card.
Okay first off, let me say that I love this little device. The widget makes it super easy to set custom settings.PRO's:~ Very compact.~ Decent video quality. Maybe not 720p, but good enough to identify faces and any identifying marks / features (tattoos, moles)~ Rotatable camera for a well hidden perspective. (It's stealth is only limited by your imagination)~ Accepts MicroSD, MicroSDHC and MicroSDXC memory cards.
I received my Zetta Z16 within just a few days of ordering it and it arrived well packaged and in good condition. The included documentation is very minimal and there is no software included. The programming widget can be downloaded from the Zetta web site.No microSD card is included. I purchased a 64gig card which according to Zetta requires formatting in a specific manner with software that again can be downloaded from their site.
Answer: The software from the company allows you to customize the behavior of the single side-mounted LED.  When placed on the "custom settings" slider, the LED can be set to only be active the first 10 seconds of the recording process, to confirm it's started.  Then the LED goes dark and stays dark until battery death.  The default behavior is a green LED for "ON" and a yellow/red error color displayed briefly for certain faults.  It has no sound output of any kind that I've ever discovered.
