CCTV Camera Installation and Maintenance
Security that starts with capturing images and is shaped around your needs.
A camera system’s value is not measured by resolution alone; field of view, lighting, recording capacity and access must all be planned. Narstek plans CCTV installation and maintenance work after assessing the site and its intended use.
Site survey and camera positioning
Areas to be monitored, blind spots, backlighting, night-time lighting and mounting conditions are assessed. Camera types and positions are planned to meet these needs.
IP and analogue system installation
Camera, recorder, network switch and cabling requirements are considered together. The suitability of the existing infrastructure for retention and compatibility with the new system is assessed before the project begins.
Recording and access configuration
Recording schedules, image quality, storage requirements and user permissions are configured. If remote access is required, the network structure and access method are assessed.
Maintenance and fault repair
Image loss, disk status, connections, power supplies and time settings are checked. Lens and housing maintenance, required software work and component replacement are carried out according to the scope of work.
Define the purpose of monitoring before deciding on the number of cameras
Monitoring general activity and capturing facial or vehicle details require different designs. Pixel density, lens, viewing distance and lighting conditions are assessed against the intended purpose; recording duration depends on the number of cameras, data rate, recording method and disk capacity.

About CCTV Camera Installation and Maintenance
Can an existing analogue system be converted to IP cameras?
The options depend on the cabling, power infrastructure and recorder specifications. A phased upgrade or retaining part of the existing infrastructure may be possible.
Does higher resolution always produce better results?
Not on its own. The lens, lighting, mounting angle, compression settings and storage capacity must all be considered together.
How are recordings checked after installation?
During commissioning, live footage, recording search and sample playback are checked. User permissions and basic operating instructions are shared with the responsible personnel.
