Safety Notice
Before you access any components located inside the unit, remove the DC cable and wait until all
the status LEDs turn off. Only qualified service personnel should access the inside of the unit.
An AC power cord is provided with a grounded attachment plug for the external power supply. To
avoid electrical shock, always use the AC power cord and plug with a properly grounded outlet
(connected to earth).
To maintain safety compliance, ensure the AC power cord has the appropriate safety approvals for
the country in which the equipment is to be installed. For North America, the AC power cord must
be a UL listed SJT NEMA 5-15 equivalent or better.
Cameras located outdoors (or outside plant: the infrastructure that is designed and installed external
to a facility or building) must be analog only. Analog cameras can be located outdoors or indoors.
When connected to an outdoor camera (analog only), the screen of the camera’s coaxial cable must
be properly grounded (connected to earth). Cable distribution systems are subject to the National
Electrical Code (NEC) in the United States and the Canadian Electrical Code (CEC) in Canada.
PoE cameras and devices must be located indoors only. The PoE (Power over Ethernet) ports must
be connected to PoE networks and PoE devices that route inside plant (the cabling and equipment
installed inside a facility or building). Do not connect to PoE networks and PoE devices that route
outdoors (outside plant).
Do not insert any foreign objects into the fan, vents, ports, or other opening in the unit.
Avis de sécurité
Avant d'accéder aux composantes internes de l’unité, retirez le câble d'alimentation DC et attendre
que toutes les lumières d’état (‘STATUS LED’) de l’unité soient éteintes. Seulement le personnel de
service qualifié a le droit d’accéder l’intérieur de l’unité.
Le câble de pouvoir AC est fournie avec un câble de mise à terre pour le bloc d’alimentation
électrique. Pour éviter tout choc, utilisez toujours le câble de pouvoir AC relié avec la prise de
courant adéquate (contenant une mise à terre).
Pour maintenir votre conformité de sécurité, assurez-vous que le câble de pouvoir AC a obtenu les
approbations de sécurité applicables pour le pays ou l’installation est faites. Pour l’Amérique du Nord,
le câble de pouvoir AC doit avoir une certification UL SJT NEMA 5-15, équivalente ou meilleur.
Les caméras situées à l'extérieur ( outside plant - à l'extérieur de l'installation: l'infrastructure
conçue et installée à l'extérieur d'une installation ou d'un bâtiment) doivent être uniquement
analogiques. Les caméras analogiques peuvent être installées à l'extérieur ou à l'intérieur.

8716P Hybrid NVR Installation Guide 8
Mandatory Regulations
Lorsque relié à une caméra installée à l’extérieur (analogique uniquement), l’enveloppe du câble coaxial
de la camera doit être mise à terre de façon adéquate. Les systèmes de distribution câblés sont sujet au
code électrique National (NEC) au États-Unis et au code électrique Canadien (CEC) au Canada.
Les caméras et appareils PoE ne doivent être installés qu'à l'intérieur. Les ports PoE (Power over
Ethernet) doivent être connectés aux réseaux PoE et aux périphériques PoE qui acheminent à
l'intérieur de l'usine (le câblage et l'équipement installés à l'intérieur d'une installation ou d'un
bâtiment). Ne vous connectez pas aux réseaux PoE et aux périphériques PoE qui acheminent vers
l'extérieur (installation extérieure).
N’insérez pas d’objets étrangers dans le ventilateur, les évents, les ports ou toute autre ouverture
dans l’unité.
Ground Connection
You must install a protective earth conductor for the 8716P Hybrid NVR.
There is a grounding stud on the back of the unit. The grounding method is described in “Ground
Connection” on page 24.
Connexion à la terre
Vous devez installer un conducteur de terre de protection pour le 8716P Hybrid NVR.
Il y a un goujon de mise à la terre à l'arrière de l'unité. La méthode de mise à la terre est décrite
dans « Ground Connection » à la page 24.
Anti-Static Precautions
Ensure proper use of an anti-static guard during installation to avoid damage to the unit from
electrostatic discharge.
Servicing Notice
The procedures contained in this publication outline how to install or service components located
inside the unit, requiring the removal of the cover. Installation and maintenance procedures
requiring internal unit access are to be performed by qualified service personnel only.
Shipping Notice

invalidate your warranty. The list of field serviceable parts includes:
• Hard drives, caddies, and cables
• Back-up batteries
• Fans
Do not power up or operate the unit with the cover removed. The cover ensures the safe operation of the
unit. Operating the unit without the cover can expose you to live electric current and can cause the hard
drives to overheat.
ATTENTION : Les procédures contenues dans ce guide décrivent comment installer ou réparer les
composants situés à l'intérieur de l'unité, nécessitant le retrait du capot. Les procédures d'installation et
de maintenance nécessitant un accès interne à l'unité doivent être effectuées uniquement par du
personnel de maintenance qualifié.
Lorsque vous travaillez à l'intérieur de l'appareil, assurez-vous de prendre des précautions antistatiques.
Toute tentative de réparation de composants de l'enregistreur qui ne sont pas considérés comme
remplaçables sur site annulera votre garantie. La liste des pièces réparables sur site comprend:
• Disques durs, caddies, et câbles
• Batteries de sauvegarde
• Ventilateurs
N'allumez pas et ne faites pas fonctionner l'appareil avec le couvercle retiré. Le couvercle garantit le

Feature Overview
Video Inputs
There are 8 analog video inputs and 8 PoE ports on the back of the unit for a total of 16 camera
channels available.
The PoE IP cameras are connected through a short Ethernet cable between the Camera
Loopback Ethernet port and the 0/1 Camera Ethernet port.
The other IP cameras (non PoE) can be added to the unit two different ways:
• Connect the camera to any one of the 8 available PoE ports. The PoE module has a built in
Ethernet switch with an aggregate port labeled Camera Loopback. This is a Gigabit Ethernet
port. The other PoE ports 1 to 8 are 10/100 Ethernet ports with PoE.
• IP cameras can also connect to the recorder through a camera network on the camera Ethernet
port (see “Ethernet Ports, USB Ports, Video and HD Monitor Output” on page 21). IP cameras
are connected using a CAT5e cable or a cable of higher performance, such as CAT6 cable.
The number of IP cameras the unit supports depends on the number of analog cameras in use.
Of the 16 total camera channels available:
• 8 are hybrid channels which can include any combination of 0-8 analog cameras and 0-8 IP
cameras.
• 8 are IP-only channels which can include any combination of 0-8 PoE IP cameras and 0-8 non-
PoE IP cameras.
Note: There is a maximum of 8 analog channels available and a maximum of 8 PoE IP channels
available.
Video Inputs on BNC Coaxial Connector
The analog video inputs are BNC coaxial connectors that support NTSC and PAL inputs.
Video Termination
Video termination for the 8716P NVR is controlled through the Visual Intelligence software. You
can use the March Networks Administrator Console application to view and modify the analog
video termination.
For more information, see the Administrator Console User Manual or online Help.
