Twisted Pair Cable*1
(BNC)
(RJ-12)
*1: For twisted pair cable, use shielded low-impedance cable with a thickness of at least AWG#22
(0.33 mm
2
).
*2: Keep the overall length of coaxial cable under 1200 meters (in the case of 5C-2V).
*3: Be sure to connect the grounding cable to ground.
Alarm In/Out Ratings
Alarm In : 5 V DC pull-up input. Drive capacity of at
lease 0.2 mA required.
OFF : 4 V DC minimum 5 V DC maximum,
or open
ON : 1 V DC maximum or short
Alarm Out : Open collector output. 16 V DC, 100 mA
maximum drive capacity
OFF : Open
ON : 100 mA maximum
* When connecting to an external device, set up the
system so the ratings are not exceeded.
Note: Do not turn off camera power within 30 seconds
after turning it on. Doing so can cause pan, tilt, zoom,
or focus to go out of position.
Precautions
• The following connections should be made by qualified service personnel or system installers in accordance
with all local codes.
• Turn off the power at the fuse box before starting the installation work, or it so could result in fire, electric shock,
personal injury, and material damage.
