320 × 240 pixels.Recommended minimum for electrical work

The industry standard for electrical scanning is 320 × 240 pixels and above. It’s the most important spec when you choose a camera for electrical work, and every camera on this page meets it.

A thermal camera shows the heat you can’t see in an electrical system: loose connections, overloaded circuits and failing parts, before they cause damage.

Most electrical faults come down to too much current or too much resistance. Both turn electrical energy into unwanted heat, and undersized conductors, loose connections or overloaded circuits can run hot enough to melt components. Scan with the system running under normal load, and a thermal image shows the problem early, while it’s still a cheap fix.

Switchboards

Loose connections, undersized conductors and overloaded circuits all run hot before they fail. A thermal camera shows that heat while the board is live and under load.

A 42° wide-angle lens takes in a whole board from close up, and a 24° lens picks out single breakers from further back.

Cameras for switchboards

Advanced switchboard scanning

For large commercial and industrial sites, and contractors scanning boards every day.

  • Up to 640 × 480 pixels on the i64, and 464 × 348 on the E86
  • FlexView on the E86: one button switches between a 24° view and a 14° close-up
  • 42° wide-angle lens on the E76, to take in a whole board from close up
  • 30 mK sensitivity on the E86 FlexView and E76, and up to 1,500°C on the E86 FlexView
  • SwitchReport runs on the i64

Entry-level switchboard scanning

For occasional checks, or a camera that’s always in your pocket.

  • 320 × 240 pixels in a pocket-size camera
  • Measures up to 450°C
  • Works with an Infratek Thermal Studio report template

Custom switchboard reporting

Finding the fault is half the job. The report is what your customer reads, and insurance companies currently expect thermal scanning on insured industrial, commercial and residential property as part of general maintenance.

If you send thermal reports to clients, they should look like they came from your business. There are two ways we can set that up, depending on where you write your reports: on your computer in FLIR Thermal Studio Pro, or on a FLIR iXX camera with SwitchReport.

Power lines and transformers

This work is usually done from the ground, at a safe distance and often in full sun. The FLIR T865 and T560 are built for it.

The T865, T560 and E96 all meet it.

All three give 640 × 480 detail, so a small hot connection still shows from a distance. One button switches to the 14° telephoto view for a closer look at a pole or a transformer, with no lens change, and the rotating lens block on the T865 and T560 lets you aim up at the lines and still see the screen. The T865 adds a viewfinder, so the image stays clear in bright sun.

Solar panels

A defective cell runs hotter than the cells around it, so a scan finds the faulty panel while the system is running, without testing each panel by hand.
