Punjab PSEB Sr. Sec. NSQF Private Security (CCTV Video Footage Auditor) study plan

Label the five functional blocks of a CCTV chain (camera, encoder/recorder, network, storage, viewing client) and state what each block contributes to the evidential value of a clip

Distinguish analogue HD formats (AHD, TVI, CVI) from IP-based systems by resolution, cabling, and where recording actually happens

Explain frame rate, bit rate, resolution, compression (H.264/H.265) and GOP length in terms of what they cost you during a later frame-by-frame review

Map a typical DVR/NVR storage layout: hard disk, RAID option, retention window, and overwrite behaviour once the disk is full

Identify the timestamp sources a recorder can use (internal clock, NTP, manual set) and why clock drift matters for evidence

Execute a full export workflow on a practice recorder or simulator: locate footage by time and camera, select the range, export in native format with the player, and record hash values before and after

Draft a chain-of-custody form that captures seizure/export time, operator identity, device serial number, storage medium ID, hash algorithm, transfer signatures and storage location

Practise writing a time-anchored event log entry (camera ID, timestamp, frame reference, observed action, confidence) instead of a narrative opinion

Differentiate native player export, proprietary format, and transcoded MP4, and state the evidential risk of each

List the failure modes that destroy footage value: overwrite before export, wrong time zone, clock drift, re-encoding, missing player, unlabelled media

Perform a systematic review pass over a 20-minute clip: first a continuous pass for context, then a frame-stepped pass for detail, logging every timestamp you stop on

Apply a written identification checklist (height relative to known objects, gait, clothing layers, carried items, vehicle model and plate legibility) rather than snap judgements

Quantify footage limitations in writing: pixels per metre at the subject's distance, lighting, motion blur, and whether a face or plate is actually resolvable

Identify and log at least three distinct event types (intrusion, loitering, vehicle movement, camera tamper or blind spot) in the same clip

Write a short bias-control note describing what you expected to see and how you prevented that expectation from shaping the log

Summarise the legal position for private security video evidence in India: BSA 2023 provisions on electronic records, the certificate requirement, and the difference between private and police-held footage

Explain why the original media or a verified bit-stream copy is preferred over a re-encoded file, and what a Section 63-style certificate must state

Apply data-protection principles to CCTV: purpose limitation, minimum retention, access restriction, notice, and handling of third-party images and bystanders

Structure an audit report: scope, methodology, evidence register, findings, limitations, recommendations, and annexures

Practise redacting personal data from a still frame and documenting the redaction in the evidence register

Describe the CCTV operator's and auditor's place in the site security organisation: reporting line, control room protocols, escalation triggers and handover procedure

Reconcile an incident report against footage and document every discrepancy between the written account and what the video shows

Explain the auditor's boundary: you report what the footage shows, you do not interview suspects, assign guilt or advise on discipline

Draft interview questions for a site supervisor about camera coverage, blind spots and maintenance history

Outline a site security survey of camera positions, fields of view and known blind spots, and note how gaps affect later audits

Identify workplace hazards specific to CCTV auditing: prolonged screen work, eye strain, musculoskeletal load, electrical and cabling hazards in equipment rooms, and lone working during night shifts

Apply ergonomic and work-rest controls to a realistic 6-hour review shift and write the schedule you would actually follow

Describe emergency response sequence for a control room: fire alarm, evacuation, power failure, and preserving recording continuity during an emergency

State the auditor's safety duties on site: PPE, escorted access, no lone entry to server rooms, reporting near misses

Explain incident reporting obligations and how to preserve footage of a safety incident without contaminating the evidence

Write findings in neutral, factual language: convert judgemental phrasing into observable description and cite the frame or timestamp for every claim

Deliver a 10-minute verbal briefing of findings to a mock client, handling two hostile questions without overstating the evidence

Apply confidentiality and conflict-of-interest rules: what may be disclosed, to whom, and how to record a disclosure request

Practise giving corrective feedback to a colleague whose log entries are vague, using specific examples

Review your own report for accuracy, clarity and consistency and produce a tracked revision

Complete two timed full-length mock papers under exam conditions and score them by domain to find weak areas

Re-drill the three weakest domain areas using your own error log rather than re-reading notes

Rehearse the end-to-end evidence workflow from export to courtroom-style presentation in under 30 minutes without notes

Assemble a one-page formula and definition sheet: hash, chain of custody, retention, certificate, report structure, event log format

Simulate a cross-examination: defend one finding against five challenges about method, bias, image quality and custody
