FAQs

Product Information

Do your surveillance products comply with Australian safety and legal standards?

Yes, all our products meet Australian safety and legal requirements and are sourced through authorised distribution channels to ensure quality and compliance.

Are your cameras suitable for both indoor and outdoor use?

Most of our product range includes dustproof and waterproof models (e.g., IP66 and above), making them suitable for outdoor as well as indoor use. We also offer indoor-only models, which should not be used outdoors. Please check the specifications for each product to ensure it meets your installation requirements.

Do your products support remote monitoring?

Yes, all our CCTV products support remote monitoring via an official app. Users can view live video feeds and control their devices remotely, making it easy to monitor your property from anywhere.

Do I need professional installation, or can I install the system myself?

We provide comprehensive technical guides to assist customers with DIY installation. However, if you prefer professional assistance, we can arrange for an expert to install the system for you. Before opting for DIY installation, please ensure you understand and comply with local regulations.

How long can recorded footage be stored? Does it automatically overwrite old recordings?

The storage duration depends on the hard drive capacity, recording mode, and settings. Most DVRs and NVRs support loop recording, meaning the oldest footage will be overwritten when storage is full. Depending on your setup and recording mode (e.g., continuous or event-triggered), footage retention can range from several days to weeks. We recommend choosing storage options that suit your needs.
