Frequently Asked Questions
How much does a commercial security system cost?
Cost depends entirely on scope, the number of cameras, whether you need access control or analytics, single or multiple sites. A small retail CCTV system is very different from a multi-floor office with access control. We always survey first and give you an itemised quote so you can see exactly what you are paying for.
Can you integrate CCTV with our existing alarm and access control?
Yes. Modern CCTV, intruder and access systems integrate well, an alarm activation can trigger recording, and a forced door can raise an alert. We design the parts to work together rather than as separate boxes.
Do we need 24/7 monitoring?
It is optional and depends on your risk. An intruder alarm can simply alert your staff, or it can be monitored 24/7 by our partner’s NSI Gold certified Alarm Receiving Centre (ARC), which responds to verified activations and handles keyholder and police escalation. CCTV can be monitored from our own 24-hour CCTV Monitoring Control Room. We advise based on your premises, insurance and risk profile.
How does access control work?
Staff or visitors present a card, fob, PIN or fingerprint; the reader checks it against your access list and unlocks the door if approved, logging every entry. Linked to your alarm, a forced door raises an immediate alert.
How do you handle GDPR for retail CCTV?
We design privacy in from the start, privacy masks to avoid recording beyond your boundary, secure storage, sensible retention (typically 30 days unless an incident requires longer), and help with the signage and notices you need. You stay the data controller; we make compliance straightforward.
Can you keep our CCTV off the main company network?
Yes, and we recommend it. We build CCTV and security systems on isolated networks with their own firewalling rather than plugging cameras into your general corporate LAN, protecting both your security system and your business data.
