Security Video Surveillance
Not every video surveillance system qualifies as security-focused. Security surveillance aims to protect individuals and assets by identifying and preventing illegal activities.
This requires continuous monitoring by an operator for quick responses during emergencies. A typical security surveillance setup includes:
- Cameras.
- Signal processing devices (switches, DVRs, video servers).
- Monitors.
- Power supplies.
Key Features of Security Surveillance
Operators often use tools like motion detection with alert systems to ensure efficiency. Advanced setups may include:
- PTZ (Pan-Tilt-Zoom) Cameras: Preconfigured to monitor various zones dynamically.
- Event-Based Alerts: Automatic full-screen display of the area where an incident is detected.
- Priority Groups: Cameras grouped by security zone importance.
Monitoring priorities may shift based on time, events, or tasks, such as:
- Monitoring entry points during shift changes.
- Watching vehicle movements.
- Detecting unauthorized access.
Equipment for Security Surveillance Systems
A security surveillance system typically includes:
Signal Transmission and Protection:
- Video transmitters and receivers.
- Surge protection devices.
PTZ Camera Controls:
- Standalone controllers or integrated solutions in DVRs or surveillance software.
Climate-Protected Equipment:
- Weatherproof enclosures for outdoor installations, protecting against extreme temperatures and environmental factors.
These components ensure reliable performance, especially in outdoor environments.
Cameras for Security Surveillance
Security surveillance systems can use analog or IP cameras, but the choice depends on the specific requirements of the system.
Field of View:
- Defines the camera's coverage area and level of detail.
- A wider field of view reduces detail, so careful selection is crucial.
Resolution:
- Higher resolution improves identification but must align with monitor capabilities.
- For IP cameras, megapixel resolutions allow zooming into specific areas without quality loss.
Recording Compatibility:
- DVRs, servers, or PCs must match the camera’s resolution to ensure high-quality recordings.
Security video surveillance systems combine advanced technology and carefully selected components to provide a reliable solution for protecting people and property. Proper planning and equipment selection are key to building an effective system.
