(10.5 V - 16 V)

• Calculation method of maximum cable length

between camera and power supply.

10.5V DC ≤ V

A − (R x 0.42 x L) ≤ 16V DC

L : Cable length (m)

R : Resistance of copper wire (Ω/m)

A : DC output voltage of power supply unit

A − 12

L standard = (m)

A − 16

L minimum = (m)

0.42 x R

A − 10.5

L maximum = (m)
