    how much current per camera?
    What type of connector do they use? (PoE?)
    Just a distribution box or power supply as well?

    if you want to go as cheap as possible. i would use an old pc power supply to supply the power, most will supply 15 or 20A, the ratings are written on the side of them. each camera i imagine would use well under 1A so there is plenty of room to add extra cameras later if you desire.

    as for fusing just put an inline fuse on each camera lead wire or get a fused distribution block. depending on the distribution block it may have led indicators and switches. if you label the fuses you may not even need led's

    here is a link to an atx power supply pinout. use the yellow 12v wires as the positive and the black ground wires as negative

    i have used pc power supplies as general power supplies for ages and they make great high current power supplies
