a shorter life span due to their reduced efficiency over time and at low
temperature. It is also possible to use a lead-acid external battery cell with 6V
output or suitable AC adapter-see below for more details.
Using an External Power Source (optional, user provided)
Optionally, you can connect an external 6V DC power source to the "DC In"
jack at the bottom of the KeepGuard Cam. It is recommended to use a power
source with a current output greater than 1000mA. However, during bright
daytime operation when no flash is required, the KeepGuard Cam can function
with much less current (>400mA). Please use a compatible power source
cable (not provided) to connect the external DC power source with the power
input jack of the KeepGuard Cam, making sure that the polarity is correct.
Note: The power connector is a 4.0 x 1.7mm coaxial DC power plug with
positive "tip" (inside pin) polarity (Radio Shack P/274-1532 or equivalent). If
both an external power source is connected and batteries are installed, the
KeepGuard Cam will be powered by the external power source. When the
batteries become weak, the low-battery indicator LED will glow blue, indicating
the batteries should be changed.
Inserting the SD Card
The KeepGuard Cams have 32MB internal memory, which can hold only about
18 photos (12MP resolution). This is handy for testing and getting familiar with
