![]() ![]() AE Ctrl - this is for controlling the auto-contrast/brightness.Timer Ctrl - there is an RTC built into the DSP which you can set, however there's no battery backup so if power is lost the RTC will be reset so we don't think its terribly useful.Power Ctrl - this is for testing the power down mode, and it seems like you might be able to have it auto-power down when there's no motion.Mirror Ctrl - we think this is so you can flip the display (if its bouncing off a mirror).Color Ctrl - this is for selecting Color or Black&White or Auto select (probably based on lighting conditions).Even we don't know what it would be good for ![]() Don't do this unless you're sure you know what you're doing since it will mess with the camera's ability. R/W Data - this is for writing raw data to the DSP chip processor.Personally, we don't suggest going in to any of them unless you really need to. There are many options for this software, here's what we think of the other buttons. Communication: 3.3V TTL (Three wire TX, RX, GND).Baud rate: Default 38400 (the datasheet claims you can change the baud rate with a command but it does not work reliably).Monitoring distance: 10 meters, maximum 15meters (adjustable).However, as far as we can tell, this is the best module on the market. The reason for all this is that it's meant for surveillance, not for nature photography. And it is sensitive to infrared light, which alters the color rendition somewhat. The module is admittedly not extremely high resolution - the maximum image size it can take is 640x480 pixels. When motion is detected, it would take a photo and save it to a disk for later analysis. So for example, normally its just displaying video to a security monitor. The serial port commands can request that the module freeze the video and then download a JPEG color image. Its meant to constantly stream TV-resolution video out of the Video pin (this is NTSC monochrome format) and also take commands from the serial port. The module was initially designed for surveillance purposes. Since it is a little confusing how this is both a snapshot and video camera, we'd like to explain it in detail now. ![]()
