Active Solid-State
The third and least common method is the emitter follower where the camera output supplies the current used for detection. In this conguration is shown in
Figure 7.

Output Relay Conguration
The relay output congurations vary based on the manufactures design. Because of these variations, the IP Reset I/O Detect input needs to operate in one of three
ways. Refer to your camera user manual for more information regarding the output relay conguration of your camera.
Passive Solid-State
The second method is similar, requiring the IP Reset to supply current to an open collector output transistor. This conguration is shown in Figure 6.

Dry Contact
The rst and most common method requires the IP Reset to supply current to the dry contacts of a relay. This conguration is shown in Figure 5.
