Security technology has shifted fundamentally over the past decade. Analogue cameras and tape recorders have given way to IP megapixel cameras, intelligent video analytics, and cloud-connected network video recorders that let you pull up a crisp 4K feed from the other side of the planet. VOLTCITY SURGE brings electrical and network engineering expertise to security installations — which matters, because most security failures trace back to the infrastructure layer: an undersized UPS, a PoE switch that resets under load, or cable runs that introduce interference and degrade image quality when it counts most.
IP Camera Systems — Resolution That Holds Up in Court
We specify and install IP cameras from Hikvision, Dahua, Axis, and Hanwha — brands whose hardware is used by government, utilities, and enterprise clients demanding forensic-grade image quality. For perimeter and carpark coverage, we favour varifocal lenses and motorised zoom cameras with IR illumination rated to 50+ metres. For internal applications, wide-angle fixed cameras with H.265+ compression balance image quality against storage costs. Every camera is PoE-powered from the network video recorder or a managed PoE switch, eliminating separate power runs and enabling remote reboot from the NVR dashboard.
What We Install and Integrate
- IP bullet, dome, PTZ, and fisheye cameras in weatherproof housings rated to IP66 and IK10
- Rackmount and desktop NVRs with RAID storage arrays for 30 to 90 days of continuous retention
- Video analytics — loitering detection, line crossing, licence plate recognition, and facial detection
- IP intercom and video doorbell systems with door-release relay integration
- Electronic access control — proximity card and PIN readers, maglocks, and electric strikes
- Monitored alarm panels with PIR, door/window sensors, glass-break detectors, and siren outputs
- Remote monitoring integration via Hikvision HikConnect, Axis Camera Station, or third-party VMS platforms
Access Control Beyond the Key
Keys get copied, lost, and handed to the wrong person. Electronic access control gives you a timestamped audit trail of every door event, the ability to issue and revoke credentials instantly, and time-based access profiles that restrict after-hours entry without a conversation. We install proximity card readers, biometric fingerprint readers, and Bluetooth mobile-credential readers linked to EM or ML maglocks and electric strikes. For larger sites, we integrate access control with your HR system so that an employee's first day triggers credential issuance and their last day triggers automatic revocation.
Alarm System Design and Monitoring
A CCTV system records what happened. An alarm system tells you it is happening right now. We design monitored alarm systems using Grade 2 and Grade 3 panels to AS 2201 standards, integrating PIR motion sensors, dual-technology detectors for false-alarm reduction, perimeter beam sensors, and glass-break acoustics. Alarm events feed to both your mobile device and an ASIAL-listed monitoring centre, with verified response options that can dispatch security patrols or police rather than relying on a siren that your neighbours eventually tune out.
Cabling, Power, and Resilience
Security systems must work when an intruder cuts the power. Every installation we commission includes a UPS with sufficient battery runtime for the NVR, switches, and access control panels to remain operational through typical outage events. Cable runs are planned for discreet routing, with surface conduit and concealed penetrations handled cleanly. Network infrastructure for security cameras is segregated onto a dedicated VLAN, keeping surveillance traffic isolated from business data and preventing cameras from becoming an entry point for network intrusion.
Frequently Asked
How much storage do I need for my CCTV system?
Storage depends on camera count, resolution, frame rate, and the proportion of time that motion-triggered recording versus continuous recording is used. We calculate storage requirements during the design phase and specify NVR configurations with appropriate RAID arrays. Typical residential systems achieve 30 days of continuous recording with 4-8 cameras at 1080p; commercial sites requiring higher resolution or more cameras are quoted with expanded storage or hybrid cloud archive options.
Can my security system integrate with my smart home or building management system?
Yes. Modern IP security platforms expose APIs and integration modules that allow alarm events to trigger smart-home actions — such as turning on all lights, unlocking an access door, or pushing a notification with a camera snapshot to your phone. We design these integrations at the system level, not as an afterthought.
Do you handle the monitoring contract as well?
We partner with ASIAL-listed monitoring centres and can arrange monitoring service contracts as part of your installation package. Alternatively, if you have an existing monitoring provider you prefer, we configure the alarm panel to their specifications and protocol requirements.
