Linea SWIR GigE 

Quick Start Guide  

This Quick Start Guide helps you to set up your camera for basic operation. Refer to the Linea SWIR GigE 

Camera User’s Manual for specifications, networking, external signal connections and application 

development. 

Note:

 screen images were made using the 1k model but instructions also apply to the 512 

model.  

Before you begin, ensure that you have: 

 

Camera power cable or Power over Ethernet (PoE) setup using a PoE Ethernet Switch or PoE Injector. 

 

Cat 5e or Cat 6 Ethernet cable. Note

:

 cable should not be less than 1 meter (3 feet) long or more than 

100 meters (328 feet) long. 

 

A computer with a second or unused Gigabit Network Interface (NIC) and any necessary imaging 

software (such as Sapera LT). 

 

Other necessary components of your system, including: light sources, camera mounts, lenses, encoders, 

etc. Please note that for best imaging performance it is recommended to use a lens designed for short 

wave infrared wavelengths between 900 and 1700 nm. Standard lenses designed for visible light may 

not transmit IR light fully nor perform to specification outside of their intended wavelength range. There 

are several manufacturers that make C-mount SWIR lenses specifically for machine vision systems. For 

assistance in selecting suitable optics for your application please contact one of our regional sales 

offices.  

Connect the Linea SWIR GigE Camera  

Before connecting power to the camera, test the power supplies. The camera requires a single voltage input 

(Min +12 V to Max +24 V) on Auxiliary connector or PoE Class 2 setup.  

 

Connect power via PoE or the 10-pin connector, but 

not both

. Although the camera has protection, 

differences in ground levels may cause operational issues or electrical faults. The Auxiliary connector 

pinout is outlined below. See the Camera User’s Manual (document number 03-032-20280) for detailed 

information and recommended cable solutions.
