Xtern-Cam® is a rugged outdoor standalone surveillance camera with inbuilt GPRS modem (receive the photos on your cell), digital image recording function, integrated night vision and inbuilt Solar Panel to give extraordinary long battery life.
The camera captures high-resolution black & white images when motion is detected and emails a selection of these to a monitoring station or mobile phone as well as storing all the high resolution images to a removable memory card for easy viewing later, on a computer or PDA. The camera can also be powered by an external 12VDC power source and can be externally triggered from a gate or door opening.
Outdoors in time lapse mode using its inbuilt Solar panel to recharge the battery during the day, Xtern-Cam® can capture and transmit wirelessly, one image every 5 minutes at night time without ever requiring the battery to be re-charged. Similarly, if Motion activated, it can capture and transmit up to 150 images every night without ever having to charge the battery.
In busy environments where the Camera may capture and transmit up to 330 images per night, the battery would still last around one month! The camera can store up to 65,000 VGA images and will optionally overwrite the oldest images when the memory card is full to enable ‘set and forget’ operation.
Xtern-Cam® is also available with a colour camera for daytime operation with optional 16mm or 8mm telephoto lenses. (more)
