Study Notes

Video Surveillance System

Video Surveillance System is an essential security requirement in Indian Railways, provided at various locations including stations, railway establishments, and coaches.
The system is operated and monitored by RPF (Railway Protection Force) staff.

IP Based Video Surveillance System (Stations & Railway Establishments)

The system is installed at various locations such as entrance/exit, platforms, waiting halls, reservation counters, parking areas, railway yards, and foot over bridges.
It captures images of commuters and public, and carries out analysis.
IP cameras complying with RDSO specs are used for stations, while CCTV cameras may be installed at non-critical locations after approval from the competent authority.

System Description

The system is end-to-end IP-based with IP cameras, video management, and video recording deployed on servers/network video recorders at RPF/GRP Thana/Posts.
The system has a provision for viewing and monitoring camera streams at Divisional HQ/centralized location or other clients connected to MPLS/IP network.

Centralized Management

A centralized management system, including video management software, is deployed in Datacenter/Centralized Location/Cloud.
The system allows for viewing and monitoring of camera streams at Divisional HQ/centralized location or other clients through MPLS/IP network.
The video data at the Data Centre/Cloud is accessible to any other centralized location or clients through MPLS/IP network.

IP Based Closed Circuit Television (CCTV) Surveillance System in Coaches

The system is provided for surveillance in coaches of passenger trains of Indian Railways.
Each coach is installed with 8 cameras, including 4 in doorways, 1 in each vestibule portion, and 2 in the aisle area.
Each coach has a video recorder unit or mobile network video recorder along with system software.

Maintenance

The equipment should be kept clean and tidy without dust.
The connectivity to switches, cameras, servers, PC workstations, storage, etc. should be checked regularly.

Do train staff and update their knowledge to maintain the VSS network more efficiently.
Do not change hardware when power supply is ON, unless it supports hot swapping.
Do not change IP addressing scheme and IP address of the working network without written permission.

IP Cameras and Network Video Recorders

IP Cameras, Network Video Recorders, and Software must comply with global ONVIF standards, specifically profiles 'S' and 'G'.
Profile 'S' ensures interoperability between Video Management Software/NVR and Camera.
Profile 'G' ensures interoperability between Video Management Software/NVR and SD (memory) Card in the Camera.

Video Management and Recording System

The system must provide secured recording for evidence purposes and user authentication to protect data integrity.
Redundant Servers/NVRs may be provided in an N+1 configuration to ensure recording and playback availability in case of Server/NVR failure.
The system must be able to continuously record for 30 days at any given point in time.

Environmental and Viewing Requirements

Equipment must operate in a typical temperature range and humidity.
Railway may specify additional temperature and humidity requirements.
Viewing of any camera must be possible from Divisional, Zonal Headquarters, and Railway Board during emergencies or as desired.

Cloud-Based Architecture

Video Analytics and Face Recognition Software must be deployed in the Cloud.
Video/data must be stored at RPF/GRP Thana/Post on External Storage Devices/Servers/NVRs and at Cloud as required.
The system must provide secured recording for evidence purposes and user authentication to protect data integrity.

IP-Based CCTV Surveillance System in Coaches

Each Coach must be installed with at least 8 cameras.
Each Coach must be provided with a Video Recorder Unit or Mobile Network Video Recorder (Mobile NVR) along with System Software.
Cameras must be installed and fixed on Coach Ceiling with vibration-proof fixing and connection arrangements.

System Components and Maintenance

The system must consist of various components, including IP cameras, Video Recorder Unit, Managed PoE Ethernet Switch, Wi-fi Access Point, Mobile NVR, System Software, Face Recognition Software, Server Hardware (Data Centre), and various types of cables.
The system must have a unique digital identification number.
Necessary action must be taken to ensure uptime better than 99.5% in consultation with the manufacturer and system integrator.
A LAPTOP along with other required accessories and tools must be provided to the supervisor maintaining the VSS system.
The complete VSS system of a station must be inspected, checked, and maintained by the concerned SSE/JE on a monthly basis.

Do's and Don'ts

Do's:
- Write configuration changes in a register.
- Properly lace internal wiring.
- Protect cables from rodents.
- Train staff and update knowledge to maintain the VSS network more efficiently.
- Use ESD wrist bands while handling VSS equipment.
- Use a good quality earth and maintain earth resistance below 1 Ohm.
- Change passwords of PC workstation/servers once a month and record it securely and confidentially.
- Take back-up of various configurations every time the configuration is changed.
- Follow procedures for clearing event and performance logs of PC workstation/server at specified intervals.
- Plan replacement of UPS batteries as per specified lifecycle.
- Check backups at least once a week.
Don'ts:
- Do not change hardware of the system when power supply is ON unless it supports hot swapping.
