Smart Security Solutions From CCTV to Keyless Entry

A robust security system encompasses multiple layers of protection, each designed to deter, detect, and respond to potential threats. Our comprehensive approach includes:

CCTV Cameras: Strategically placed CCTV cameras provide real-time monitoring of your property, both indoors and outdoors, allowing you to keep a watchful eye on your premises and deter potential intruders.

Alarm Systems: Advanced alarm systems act as a first line of defence, detecting unauthorised entry and triggering loud alarms to alert you, your neighbours, and the authorities.

Access Control Systems: Secure access control systems restrict entry to your property, ensuring that only authorised individuals can gain access.

Back-to-Base Monitoring: Our 24/7 back-to-base monitoring service provides constant surveillance of your property, ensuring that any alarms or security breaches are immediately detected and responded to.

Intercom Systems: Intercoms facilitate secure communication between individuals inside and outside your property, enhancing access control and visitor management.

We've used O'Brien Electrical a few times now and our experience with them has been a pleasure each time. The assistance from Eloise and her prompt attention to my inquiries made booking the service very easy. Paul carried out each job with good knowledge and did exactly as instructed , he arrived on time and was always polite and friendly. I will use them again for any electrical work

Trudy C. -

The team at O’Brien Electrical Alexandria were prompt and professional from the get go. From Eloise in the office to Darren who attended they didn’t stop till the job was completed successfully. I didn’t know that this level of service still existed. I know who to call next time there is an issue. Prompt, professional and good value. Highly recommend.
