The LZ-5S/POL is a passive device and allows to distribute the power supply.
The housing of the LZ-5S/POL has been prepared for mounting with screws to a wall or with a tie to a mast (tie, screws - not included).
An unquestionable advantage of employing the LZ-5S/POL in monitoring systems powered from a central point is additional tamper protection. Without individual protection for each power line, an intruder can stop powering of the whole system just by shorting out the power line of the single camera.
