CAUTION!
The declared degree of protection of the camera relates to its housing and does not take into account the possibility of moisture infiltration into the camera by connection cables. Connection cables protection through i.e. sealing up is the camera installer duty. The manufacturer is not liable for any camera damages caused as a result of failing in performing that activity by installer, which also means that camera damaged in that way is not subject to warranty repairs.
CAUTION!
Camera power supply connector is not hermetic. Installer should seal this connector by himself. Camera can be supplied using external power supply unit corresponding with the camera parameters or by using RJ45 network socket and PoE (802.3af) power supply unit. If you’re using external power supply please connect wires according to polarisation shown on picture:

CAUTION!
In order to provide protection against voltage surges/lightning strikes, usage of appropriate surge protectors is advised. Any damages resulting from surges are not eligible for service repairs.

2.3. Camera mounting
To mount a camera please follow the instructions below:

Place the mounting template on the surface on which the camera is to be installed and mark the drilling points.
Drill holes for mounting screws and cables in the marked places
Drill a hole for the signal cable at the connection point (if necessary)
Connect the cables and fix the camera foot using the provided pegs and screws
Loosen the lock screws “A”
Adjust the camera position
Tighten the “A” lock screws
Adjust the field of view with buttons “T” and “W” (described in point 2.1.) or with the zoom+ /zoom- buttons available after logging into the camera via a browser.

CAUTION!
Please note that the wall or ceiling must have enough strength to carry the IP Camera.
CAUTION!

Furthermore, when installing the bracket on rough/uneven surfaces, please additionally seal the junction with appropriate sealing mass. Please pay special attention to any mounting holes and if they are a loop-through ones, seal them too.

2.4. Starting the IP camera
To run NOVUS IP camera you have to connect ethernet cable between camera and network PoE switch with PoE support (IEEE 802.3af).
You can also power it from 12VDC power supply compatible with camera power supply specification. The recommended way to start an IP camera and perform its configuration is a direct connection to the network switch which is not connected to other devices. To obtain further information about network configuration parameters (IP address, gateway, network mask, etc.) please contact your network administrator.

Connection using network switch with PoE support
Connection using external power supply and network switch
Connection using external power supply directly to the computer

Information:
Power supply adapter is not included. Please use power adapter with parameters specified in user ‘s manual.

2.5. Initial configuration via the web browser
The default network settings for NVIP-4H-6522M/F-II camera are :

IP address – 192.168.1.200
Network mask – 255.255.255.0
Gateway – 192.168.1.1
User name – root
Password – pass

Knowing the camera’s IP address you need to appropriately set PC IP address, so the two devices can operate in one network subnet ( e.g. for IP 192.168.1.1, appropriate address for the camera ranges from 192.168.1.2 to 192.168.1.254, for example 192.168.1.60). It is not allowed to set the same addresses for camera and PC computer.
You can either set a network configuration (IP address, gateway, net mask, etc.) of NOVUS IP camera yourself or select DHCP mode (DHCP server is required in this method in target network) by using web browser or by NMS software. When you use DHCP server check IP address lease and its linking with camera MAC address to avoid changing or losing IP address during device operation or network/ DHCP server breakdown. You have to remember to use a new camera IP address after changing network parameters.
After network setting configuration has been done, the camera can be connected to a target network.

2.6. Security recommendations for network architecture and configuration
CAUTION!
Below are shown security recommendations for network architecture and configuration of CCTV systems that are connected to the Internet to reduce the risk of unauthorized interference with the system by a third party.

Absolutely change the default passwords and user names (if the device gives this possibility) of all applied network devices (recorders, cameras, routers, network switches, etc.) to the severely complexity password. Use lowercase and uppercase letters, numbers, and special characters if there is such possibility.
Depending on the available functionality in the order to restrict access to the used network devices at the administrator account level, it is recommended to configure the users accounts accordingly.
Do not use DMZ function (Demilitarized zone) in your router. Using that function you open the access to recorder system from the Internet on all ports, which gives possibility for an unauthorized interference with the system.
Instead of DMZ use port forwarding redirect only the ports which are necessary for the performance of the connection (detailed information about ports of communication in different models of recorders, cameras, etc. can be found in the operating instructions).
Use routers with firewall function and make sure it is enabled and properly configured.
It is recommended to change the default network communication port numbers of used devices if there is such possibility.
If used network devices has a UPnP feature and it is not used, turn it off.
If used network devices has a P2P feature and it is not used, turn it off.
If used network devices support HTTPS protocol for connection, it is recommended to use it.
If used network devices support IP filtering for authorized connections function, it is recommended to use it.
If used recorder has two network interfaces it is recommended to use both of them to physically separate network for cameras and network for Internet connection. The only device in the system, accessible from Internet will be recorder – there will be no physically access directly to any camera.

NETWORK CONNECTION USING WEB BROSWER

3.1. Recommended PC specification for web browser connections
