1.0 Introduction
The 7420HD series camera system is a digital high denition day/night indoor
xedpositiondomecamerasystem.Thecamerasupports1080p30resolution
and H.264 and Motion JPEG (M-JPEG) standards for video compression.
The 7420HD series camera system is IP (Internet Protocol) based with a full func-
tion built-in web server. Operator functions and administrative features are con-
trolled from the standard Internet browser window.
The camera system has built-in Power over Ethernet (PoE) in accordance with
IEEE 802.3af PoE standard. Power can come from a power supply within a PoE-
enabled networking device such as an Ethernet switch or from a midspan injector. Please refer to section
2.1 for additional information.
OptionalashmemorySDHCClass6cardswithcapacityof8,16,and32GBareavailableforinternal
video recording/storage. (Future option.)
The camera system has programmable input/output lines. The lines can be used for alarms or other user
denedcontrols.(Futureoption.)
Three mounting holes allow the Camera to be mounted on the surface.
For more information on 7420HD specications and a datasheet, please refer to the Cohu website:

2.0 Installation
NOTE:All graphics contained within this document, including screenshots and other displays, are for refer-
ence use only and are subject to change.
This chapter covers the general installation and cable requirements of the 7420HD series.
Before starting installation:
• Choose the installation mounting method. See chapter 3 of this manual.
• Verify that the cables can be routed to the location of the mounting assembly.
• Installationshouldbedoneonlybyqualiedpersonnel.
This assumes that the other end of the cable is properly connected to a source of power and any other
required equipment.
See section 3.1 for details on the installation procedure.
2.1 Power over Ethernet (PoE)
The 7420HD Camera is compliant with IEEE 802.3af standard. Power to the Camera is supplied through the
network.TwotypesofPoEimplementationsarespeciedbythestandard:
• Endspan PoE - power is applied directly by the switch to the Camera. This method requires the
deployment of a PoE-enabled switch.
• Midspan PoE - power is supplied by an injector placed between an existing non-PoE switch and
the Camera.
The PoE injector is supplied with the Camera when the 7425-xxxx option is ordered. Please refer to the
Cohu web page www.cohu-cameras.com/products/74200hd.html for ordering information. The PoE injector
selected for use with 7420HD should meet the following requirement:
• be compatible with IEEE 802.3af standard
Figures 1 and 2 show interconnection diagrams for 7420HD:
• Figure 1 shows a setup of the Camera with PoE-enabled switch.
• Figure 2 shows a typical set up interconnection diagram for the Camera using the PoE injector with
non-PoE switch.
These diagrams give some idea of a typical installation. Each installation site will have its own unique re-
quirements.
2.2 Ethernet 802.3 PoE Connector
For Ethernet: CAT5e or better cable is recommended. For distances up to a maximum of 100 meters (328
feet), use CAT5e cable with four pairs of copper wire, 24 AWG.
When wiring to the Ethernet pins, be sure to consider whether they should be wired for the NIC (network
interface card) in a PC or for system connections to a hub, switch, router, or similar device.
All Ethernet wiring should be done in accordance with TIA/EIA568-C standards set.

3.0 Mounting Methods
The 7420HD isdesignedforindoorinstallation.Thecameracanbemountedtoaatsurfacesuchasawall
or ceiling. Ashort CAT5 pigtail is pre-installed through the back of the dome base for cable routing through
the mounting surface. Use appropriate bolts for the ceiling/wall materials to secure the camera. Each site
will have its own unique requirements.
3.1 Installation Procedure
The sequence of installation can vary from site to site.
3.1.1 Prepare the Mounting Location
• Identify the mounting location so that the area of
interest can be viewed by the camera/lens combi-
nation.
• Determine the cable routing method. Two cable
routing methods are available:
• Routing the pre-installed cable through the
back cable access hole and through the
mounting surface.
• Routing the customer system cable into
the dome base through the side cable ac-
cess hole.
• Use the provided template to drill the mounting
holes for the mounting plate.
IMPORTANT: The camera system is a xed position camera system. Therefore, camera direction will
be determined by the orientation of the mounting plate. The camera has a lateral adjustment range of
+/- 50° from the reference arrow (camera direction) on the template. Be sure that the desired areas of inter-
est can be reached within this adjustment range. See Mounting Plate Dimensions.
• Install the mounting plate to the mounting surface using appropriate fasteners (not supplied) and
run the system cable to the mounting location.
WARNING:
It is the user’s responsibility to ensure that the mounting methods are safe and adequate for the location.
CAUTION:
Electrostatic sensitive electronic equipment is inside. Observe precautions for handling ESD (Electro-
static Sensitive Devices).

3.1.2 Prepare the Camera for Installation
• Detach the dome top from the dome base by removing the fourAllen screws with the provided 3mm
Allen wrench. Keep the rubber gasket with the dome top.
CAUTION: The electronics package is sensitive to damage from electrostatic discharge. Do not touch any
of the circuit boards or electronic components in the electronics module.
• If the back cable access hole with pre-installed CAT5 pigtail is used, then the camera is ready for
mounting.
• If the side cable access hole in the dome base is used then the camera electronics package
should be removed to access the internal RJ45 connector:
• Remove the four M4 Phillips head screws and slide the electronics package to remove it
from the dome base. Disconnect the internal CAT5 pigtail cable.
3.1.3 Mounting the Dome Base
• Connect the customer cable to the CAT5 pigtail end (if the back cable access hole is used).
• Engage the posts on the dome base with the holes in the mounting plate and rotate the dome base
clockwise to lock the posts into the mounting plate.
• If the camera electronics package has been removed (if the side cable access hole is used):
• Run the customer system cable into the dome base and connect to the internal RJ45
connector on the electronics package.
• Tuck the cable into the dome base.
• Place the electronics package into the dome base and tighten the four M4 Phillips head
screws.

4.5 Checkout Procedure
When the power is applied to the Camera the initialization process begins. All Cohu Cameras initialize on
power-up using stored default parameters within the camera’s non-volatile memory. The default IP address
assigned to the Cameras at the factory is 192.168.2.150. For information on accessing the Camera using
the Helios Web Interface see section 5.2.
If the Camera does not operate when the power is applied, check for:
• Proper input voltage
• Proper cable connections
After communication with the Camera has been established and video stream has been started, various
functions should be tested to verify proper operation.
