Camera Specifications
Definitions
Client: A computer or device that makes use of a server. As an example, the client might request a particular file from the server.
DHCP: Dynamic Host Configuration Protocol. In this procedure the network server or router takes note of a client’s MAC address and assigns an IP address to allow the client to
communicate with other devices on the network.
DNS Server: A DNS (Domain Name System) server translates domain names (ie: www.vikingelectronics.com) into an IP address.
Ethernet: Ethernet is the most commonly used LAN
technology. An Ethernet Local Area Network typically uses twisted pair wires to achieve transmission speeds up to 1Gbps.
Host: A computer or device connected to a network.
Host Name: A host name is a label assigned to a device connected to a computer network that is used to identify the device in various forms of network communication.
Hosts File: A file stored in a computer that lists host names and their corresponding IP addresses with the purpose of mapping addresses to hosts or vice versa.
Internet: A worldwide system of computer networks running on IP protocol which can be accessed by individual computers or networks.
IP: Internet Protocol is the set of communications conventions that govern the way computers communicate on networks and on the Internet.
IP Address: This is the address that uniquely identifies a host on a network.
LAN: Local Area Network. A LAN is a network connecting computers and other devices within an office or building.
Lease: The amount of time a DHCP
server reserves an address it has assigned. If the address isn’t used by the host for a period of time, the lease can expire and the address can be
assigned to another host.
MAC Address: MAC stands for Media Access Control. A MAC address, also called a hardware address or physical address, is a unique address assigned to a device at the factory. It
resides in the device’s memory and is used by routers to send network traffic to the correct IP address. You can find the MAC address of your K-1775-IP phone printed on a white label
on the top surface of the PoE LAN port.
Router: A device that forwards data from one network to another. In order to send information to the right location, routers look at IP Address, MAC Address and Subnet Mask.
RTP: Real-Time Transport Protocol is an Internet protocol standard that specifies a way for programs to manage the real-time transmission of multimedia data over either unicast or multicast
network services.
Server: A computer or device that fulfills requests from a client. This could involve the server sending a particular file requested by the client.
Session Initiation Protocol (SIP): Is a signaling communications protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet
Protocol (IP
) networks. The protocol defines the messages that are sent between endpoints, which govern establishment, termination and other essential elements of a call.
Static IP Address: A static IP Address has been assigned manually and is permanent until it is manually removed. It is not subject to the Lease
limitations of a Dynamic IP Address
assigned by the DHCP Server. The default static IP Address is: 192.168.154.1
Subnet: A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example,
all devices with IP addresses that start with 100.100.100. would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons. IP networks
are divided using a subnet mask.
TCP/IP: Transmission Control Protocol/Internet Protocol is the suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones
being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data over networks.
TISP: Telephone Internet Service Provider
WAN: Wide Area Network. A WAN is a network comprising a large geographical area like a state or country. The largest WAN is the Internet
.
Wireless Access Point (AP): A device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. The AP usually connects to a router (via a wired
network) as a standalone device, but it can also be an integral component of the router itself.
Wireless Repeater (Wireless Range Extender): takes an existing signal from a wireless router or access point and rebroadcasts it to create a second network. When two or more hosts
have to be connected with one another over the IEEE 802.11 protocol and the distance is too long for a direct connection to be established, a wireless repeater is used to bridge the gap.

A. Mounting
The K-1275-IP is designed to be installed in a sheltered location, and is not meant to be used outdoors. For outdoor
applications use the K-1275-IP-EWP. The K-1275-IP can either be installed as a flush mount unit using the included
rough in box, or as a surface mount unit using an optional VE-5x10 or VE-5x10-SS. The rough in box uses the inner
set of four holes on the face plate while the VE-5x10 uses the outside set of holes. A set of dummy screws and nuts are
provided to fill the unused mounting holes.
NOTE: Write down the MAC Address (found on the RJ-45 jack) as this may be needed to identify the unit after installation.
B. Changing the Directory
To install a directory, remove the four screws that
mount the directory lens to the front of the K-1275-IP
using the included Allen wrench. Insert a paper
directory behind the lens and secure the two back onto
the front panel being careful to align the names with
the front panel graphics.
Note: To print directory forms for the K-1275-IP, go to
www.vikingelectronics.com and enter “930” in the DOD
field at the top of the page for a direct link to the PDF.

* Note: Up to 150 ft video cable run length can be achieved using CAT5E or CAT6 cable. Longer cable runs can be used if a passive or active video Balun
transceiver is used on each end of the cable. Generally, passive transceivers can achieve up to 750 ft cable runs where active transceivers can achieve up to
3000 ft runs depending on cable type, etc. The type of video balun transceiver required is specific to your cable run length. For more information on video balun
transceivers go to: www.northernvideo.com.
Caution: When routing CAT5E or CAT6 cable, maintain a minimum distance of 3 ft from any parallel high voltage wire (110 VAC) and a minimum of 2 ft from
crossing any high voltage wire. For installations where RF noise is expected (commercial applications) or wire runs are near high voltage (110 VAC) wires, a
shielded video cable such as RG6 is recommended.
C. Using a Video Encoder to Convert the Analog NTSC Video to IP
D. Adjusting the Camera
Axis manufactures video servers that encode analog video signal for transmission across IP
network or the internet. The single channel model M7011 is shown. Supplied software allows
you to access Axis units connected to the network (auto-discovery) and program them via a
web page interface. The video can then be monitored from any location on the network.
For more information, go to www.axis.com
The camera can be tilted and rotated to your desired
position. A portable service (test) monitor can be used
to determine the correct viewing angle during
installation.
Important: To prevent the edge of the faceplate from
being viewed in the video image, do not rotate the
camera beyond 30 degrees or tilt beyond 20 degrees.

The front panel of the K-1275-IP is mounted using security Torx screws to help prevent intruders from removing the panel
and accessing the on board door strike/gate control relays. For applications requiring additional security, a Viking model
RC-4A remote relay controller can be used. The relay controller is mounted securely inside the building and connected to
the same LAN as the K-1275-IP. The on board door strike relays would not be used in this case as the K-1275-IP will send
an encrypted message to the RC-4A to activate its relays which control the door strikes/gates. For more information, see
DOD# 582 at www.VikingElectronics.com.
Up to 4 K-1275-IP’s can communicate with one RC-4A allowing you to securely control four entrances.
When using an RC-4A for remote relay control the K-1275-IP’s relays should be set to “External” in the PC programming.
Note: If the K-1275-IP loses communications with the RC-4A, the LED on the front panel of the K-1275-IP will flash 3 times
every 2 seconds indicating the communication error. If this error occurs, make sure the RC-4A is powered, has a network
connection and has the correct IP address and security code of the K-1275-IP displaying errors.
