spike that single stage gas tube protectors let leak through. The diode array’s low capacitance assures that the

protector will not degrade the high-speed signals. The RS-485 control line is connected to the protector via its

screw terminal blocks. The terminal blocks are removable to ease wiring.

AC and DC Power Lines

The PTZ camera’s power lines are also protected using a 3-stage design. This provides superior protection from

transients and surges. The first stage is comprised of a differential gas discharge tube. Stage two is a pair of

suppression coils and the final stage is a 5000 Watt uni-polar Transient Voltage Suppression (TVS) Diode used on

the AL-VDP DC models. For AL-VDP AC models, a Metal Oxide Varistor (MOV) is used. Power lines are connected

to the protector via high current rated screw terminals.

Weatherproof Design

These units feature a weatherproof ABS enclosure with gasketed cover and concealed mounting holes. Water tight

cable glands provide entry and exit points for cables. A ground clamp on the enclosure’s exterior provides a tie

point for earth ground.
