A credible security system is not a consumer kit screwed to a fence post — it is a layered, professionally engineered solution covering surveillance, intrusion detection, and access control. PrismTech Electrical designs systems that integrate all three layers into a unified platform, giving property owners a single interface for live viewing, alarm management, and gate or door access, whether they are on-site or halfway around the world.
IP CCTV Systems and Network Video Recorders
We install commercial-grade IP cameras from manufacturers including Hikvision, Dahua, and Axis, selected for their optical performance, weather resistance, and long-term firmware support. Resolution starts at 4 megapixels for standard coverage zones and scales to 4K for entry points, high-value storage areas, or licence plate capture requirements. Cameras are powered via Power over Ethernet (PoE) switches, eliminating separate power cable runs and simplifying future repositioning.
All footage is recorded to a dedicated Network Video Recorder (NVR) sized to provide the retention period required by your insurer or your own risk assessment — typically 30 to 90 days of continuous recording. NVRs are installed in a secure, ventilated cabinet with UPS battery backup so recording continues during mains interruptions. Remote access is configured via encrypted HTTPS connections, with multi-factor authentication enforced as standard. We do not use port-forwarding configurations that expose your NVR directly to the public internet.
Intrusion Alarm Panels and Monitoring
PrismTech installs hard-wired alarm panels — including DSC, Bosch, and Paradox series — that communicate over both cellular and broadband networks for redundant signalling. Wired passive infrared (PIR) detectors, door and window reed switches, glass break sensors, and dual-technology detectors are positioned based on a formal site walkthrough that maps likely intrusion paths rather than convenient mounting locations.
Panels can be connected to a Grade A1 monitoring centre that receives alarm signals and dispatches response in accordance with your pre-arranged protocol. For commercial sites, we prepare the compliance documentation required by insurers and building managers. All wiring is run inside conduit or within wall cavities, producing a clean installation that resists tampering and presents professionally to clients and tenants.
Access Control: Electronic Locks, Intercoms, and Keypads
Electronic access control replaces physical keys with auditable credentials: proximity cards, PIN codes, smartphone Bluetooth credentials, or biometric readers. PrismTech installs magnetic lock systems, electric strike frames, and motorised deadbolts wired to access controllers that maintain an event log of every entry and exit. Integration with your CCTV system means each access event triggers a camera clip, creating an automatic visual audit trail without manual review.

Licensed Electrical Installation — Not Just Security Fitting
Many security companies subcontract electrical work or operate under low-voltage exemptions that limit what they can legally install. Every PrismTech security installation is performed under a full electrical contractor's licence, meaning we handle 240V power circuits for cameras, access panels, alarm sirens, and intercom units without the grey-area workarounds common in the industry. This matters for insurance claims, building certification, and warranty coverage.
After installation, we provide a full system handover including camera placement maps, NVR login credentials stored in your choice of password manager, panel user codes, and a plain-language guide to daily operation. We also offer annual service agreements covering firmware updates, camera lens cleaning, battery testing, and a functional test of all detection zones.
Frequently asked questions
How many cameras do I need for my home or business?
Camera count depends on the number of entry and exit points, the size of the perimeter, and any specific areas requiring close monitoring — such as safes, server rooms, or cash handling areas. As a practical starting point, most residential properties require four to eight cameras to cover all entry points and key outdoor zones. Commercial sites vary widely. We conduct a site assessment before quoting so the design reflects actual coverage requirements rather than a generic package.
Can I view my cameras remotely on a smartphone?
Yes. We configure secure remote access using the NVR manufacturer's encrypted cloud relay or, for clients who prefer it, a private VPN connection to your local network. You can view live feeds, review recorded footage, and receive motion-triggered push notifications from the manufacturer's iOS or Android app. We test this configuration with you during the handover so you leave confident in day-to-day operation.
What is the difference between a monitored alarm and a self-monitored system?
A professionally monitored alarm transmits signals to a Grade A1 monitoring centre staffed around the clock. Operators follow your pre-agreed response protocol, which may include contacting you, nominated keyholders, or dispatching a security response vehicle. A self-monitored system sends alerts directly to your phone, leaving response entirely up to you. Professionally monitored systems are generally required by commercial insurers and are strongly recommended for properties that are unoccupied for extended periods.
Will the CCTV cabling be visible on the outside of my building?
We aim to minimise exposed cabling on all installations. Cabling is run inside conduit on external walls, concealed within roof cavities where possible, and finished with colour-matched conduit where surface mounting is unavoidable. Camera housings are selected to complement the building's facade. The result is a professional, tamper-resistant installation rather than a collection of cables draped across fascia boards.
