Security Television Systems (STS) provide comprehensive monitoring of protected areas using a complete set of technical equipment including cameras, data transmission lines, video processing and recording devices, and display units 📺.
Technical Equipment
Cameras:
Security television systems use various types of cameras for video monitoring. These cameras are generally categorized as:
- Analog Cameras:
Often associated with traditional CCTV systems (CVBS), which have evolved into modern formats such as AHD, TVI, and CVI—offering high-quality images at a budget-friendly price. - IP (Digital) Cameras:
Designed for use in local or even global networks, these cameras provide high-resolution imagery and support advanced video analytics.
Cameras are also differentiated by installation location:
- Outdoor Cameras:
Built with robust climate protection and advanced features like automatic iris control, electronic shutter, automatic gain control, and backlight compensation. - Indoor Cameras:
Optimized for interior environments.
Recording Devices (Recorders):
These units process, record, and display video signals. While dedicated video recorders are common, PCs or dedicated video servers can also serve as recorders in smaller systems.
Design & Installation
Project Planning:
When designing a security television system, it’s essential to:
- Determine the system’s purpose and select the appropriate type (analog vs. IP), resolution, and focal length of cameras.
- Account for environmental conditions that might require vandal-proof or covert models.
- Choose the right capacity and number of HDDs for the required video archive depth.
Installation Considerations:
Effective installation involves careful cable management (including proper bend radius for conductors) and optimal camera placement. Key factors include:
- Field of View:
Ensuring cameras cover the desired area while avoiding glare and other visual interference. - Accessibility:
Cameras should be placed where they are both secure from tampering and accessible for routine maintenance. - Compromise & Optimization:
Balancing ideal viewing angles with practical considerations such as maintenance access and environmental challenges.
Integration with Other Systems
Modern security television is often integrated with other systems to enhance overall security. Some common integrations include:
-
Alarm Systems:
For instance, on a private property, an alarm may send a GSM alert to the owner. With integrated security television, remote access allows verification of whether an alarm is a false trigger or a genuine intrusion. -
Pan-Tilt-Zoom (PTZ) Systems:
In industrial settings, speed dome cameras (e.g., Speed Dome) can be preset to monitor critical areas. When an alarm triggers, the camera automatically adjusts to capture the exact zone of interest. -
Access Control Systems (ACS):
On premises with strict access protocols, security television can work with ACS to transmit live images of a person requesting access. This image can be automatically verified against stored profiles, with the process fully or partially automated for increased efficiency.
The evolution of security television has blurred the lines between “video surveillance” and “television monitoring.” Today, both terms generally refer to the conversion of images into electrical signals, their transmission, processing, and display on monitors. While “video surveillance” is the more popular term, the principles behind security television remain the same.
