At Shadow Surveillance, we go beyond standard alarm and CCTV systems by offering a comprehensive key holding and alarm response service across Brighton, Hove, and Sussex. This added layer of protection ensures that your property is always looked after — day or night. If your alarm is triggered or CCTV picks up unusual activity, and you're unavailable or need support, one of our high-profile, SIA-licensed mobile patrol units will respond promptly. All vehicles are GPRS-tracked for accountability and typically arrive within 20 minutes of an alert. Our service runs 24/7, 365 days a year — including weekends and public holidays — providing around-the-clock peace of mind.
