ISI Surveyor Thermal Imager Key Features
The ISI Surveyor thermal infrared camera (TIC) is a must have piece of equipment for any fire fighter agency. The unit has a thermal imaging sensor array size of 320 X 240 pixels. This is ultra high thermal resolution. Today’s newest thermal imaging cameras TIC’s for firefighting are typically only 160×120 pixels. The Surveyor is 4 times the resolution at 320×240. With the typical thermal imager having 4 times LESS resolution than this device, you can’t get better for your money! The ability to charge the battery in the camera and on a charger makes it so you can charge two batteries at once and won’t have to worry about running out of power. The ISI Surveyor was designed to withstand drops and impacts from up to 3 feet high at any angle the thermal imager lands. It has a Raytheon Digital BST core that makes the picture and image quality much greater in conjunction with the advanced digital electronics inside. We have Video Out wireless transmitters but our Supply is limited so call today to ensure you get one with you ISI Surveyor!

This is a once in a generation opportunity to get a fully fire rated waterproof TIC (thermal image camera) at a low price. These REFURBISHED models are in limited supply and once gone they are gone for good!
