IT Consultancy and Data Network Solutions
A robust, documented infrastructure for your cameras, access control and office network.
Most security systems now operate over a network: IP cameras, recorders, access control panels and remote monitoring. If the network infrastructure is inadequate, even the best camera can produce an intermittent feed. Narstek provides structured cabling, fibre, cabinet organisation, switch and PoE planning, wireless networking and IT consultancy alongside security systems, with a single point of contact.
Site survey and network design
Existing cabling, cabinets, switches and internet connection are inspected on site. The number of users and devices, camera bandwidth, and distances between floors and buildings are assessed to determine copper and fibre cable routes and cabinet locations.
Structured cabling and fibre
Cat6 / Cat6A copper cabling, fibre links between buildings and floors, patch panel and outlet installation are provided. Every line is labelled and tested, and a line schedule is supplied with the test results.
Cabinet, switch, PoE and Wi-Fi
Cabinet cable management, managed switches and PoE budgets, and UPS power continuity are planned. Office and guest wireless networks are arranged according to the coverage requirements of the access points.
Network segmentation and IT consultancy for security systems
Camera, access control and office traffic are separated using VLANs; remote access is configured using secure methods. The business is advised on device inventory, password and permissions management, and backup and update plans.
Why should the camera network be separate from the office network?
IP cameras transmit a continuous, high volume of data. When they share a network with office computers, video interruptions and general slowdowns can occur; in addition, an unupdated camera can become a gateway into the rest of the network. Grouping cameras and security devices on a separate VLAN or physically separate switches, correctly calculating the PoE budget, and controlling external access can reduce these risks.
About IT Consultancy and Data Network Solutions
Can existing cabling be reused?
Lines are tested; if the category, length and test results are suitable, they can be retained. Unlabelled and disorganised lines are documented first, and only the problem sections need to be replaced if required.
How many cameras require a dedicated switch?
The key factors are the cameras’ bit rates, PoE power requirements and the switch’s total PoE budget, rather than the number of cameras alone. During the site survey, calculations are made based on the camera list and a suitable switch configuration is recommended.
Should fibre be used for connections between buildings?
A single copper cable run has a limited maximum length, and connections between buildings carry risks from lightning and differences in earth potential. Fibre is therefore generally preferred for connections between buildings and over long distances.
Can we use the consultancy service on its own?
Yes. Reviewing the existing network, reporting issues and prioritising recommended actions are available as a standalone service; implementation can be carried out by your team or by Narstek.
