outlet, contact a locally certified electrician to replace the obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
Alternately, this unit may be equipped with a 3-pole grounding plug (a plug with a third pin for
earth grounding). This safety feature allows the plug to fit into a grounded power outlet only. If
unable to insert the plug into the outlet, contact a locally certified electrician to replace the
obsolete outlet. Do not defeat the safety purpose of the grounding plug.
Moving - Disconnect the power before moving the unit. Move the unit with care. Excessive
force or shock may damage the unit and the hard disk drives.
Outdoor signals - The installation for outdoor signals, especially regarding clearance from
power and lightning conductors and transient protection, must be in accordance with NEC725
and NEC800 (CEC Rule 16-224 and CEC Section 60).
Permanently connected equipment - Incorporate a readily accessible disconnect device in the
building installation wiring.
Pluggable equipment - Install the socket outlet near the equipment so it is easily accessible.
PoE - Never supply power via the Ethernet connection (PoE) when power is already supplied
via the power connector.
Power disconnect - Units have power supplied whenever the power cord is inserted into the
power source. The power cord is the main power disconnect for all units.
Power lines - Do not locate the camera near overhead power lines, power circuits, or electrical
lights, nor where it may contact such power lines, circuits, or lights.
Rack-mount - Read the following guidelines for rack-mounted equipement:
– Ventilation - Do not place this unit in a built-in installation or rack without proper
ventilation or adhering to the manufacturer's instructions. The equipment must not
exceed its maximum operating temperature requirements.
– Mechanical loading - Properly mount the equipment in a rack to prevent a hazardous
condition due to uneven mechanical loading.
Video loss - Video loss is inherent to digital video recording; therefore, Bosch Security
Systems cannot be held liable for any damage that results from missing video information. To
minimize the risk of lost digital information, Bosch Security Systems recommends multiple,
redundant recording systems, and a procedure to back up all analog and digital information.
Warning - This device is intended for use in public areas only. U.S. federal law strictly prohibits
surreptitious recording of oral communications.
