Do some sensors have built in EOL resistors?

[johnnynine]

Should I see EOL resistors near the window or door sensors or are they built in to the sensor?

If so does anyone have a picture of this so I know what to look for?

They are intended to go at the sensor end. Lazy installers put them at the panel. Some sensors, like the George Risk ones can have the EOL built in but that is not too common. If the panel does not require them, like the M1, sometimes they are left out alltogether.
