CCTV and Video Surveillance

Camera placement, storage sizing and control-room design planned from a coverage survey, not a generic camera count.

A security control room at night, an operator silhouetted at a curved desk facing a wall of CCTV monitors showing car park, corridor, loading bay and entrance views.
CCTV and video surveillance reference systemFixed, dome and number-plate cameras across the site are powered and connected over a PoE switch on a dedicated CCTV VLAN. Streams record to an NVR or video management server, which writes to sized storage. Operators view live and recorded video from a control room, and off-site viewing is reached through an authenticated encrypted gateway rather than by exposing the recorder to the internet.CCTV VLANEncryptedFIXED BULLETPerimeter approachDOMEInterior and lobbyNUMBER PLATEGate and yardPOE SWITCHPower and dataNVR / VMSRecording and searchSTORAGESized to retentionCONTROL ROOMLive and reviewSECURE REMOTEAuthenticated access

Reference system

A site plan with camera fields, edge network, recording, control room and secure remote viewing.

Symptoms

When this matters

If any of these describe your environment, this is the conversation to have.

  1. 01Camera coverage was decided by budget rather than a survey of actual blind spots.
  2. 02Recordings are lost or overwritten before an incident is even reported.
  3. 03Nobody can say with confidence how many days of footage the system retains.
  4. 04Legacy analogue or ageing NVR hardware is failing and needs a migration plan.
  5. 05Remote viewing exists but access is not properly secured.

Scope

What KINNEX delivers

Surveillance is only as useful as its weakest link — a blind spot, an under-sized disk or an unsecured remote-viewing link undermines the whole system. KINNEX treats CCTV as network infrastructure with a retention policy, not a set of cameras bolted onto a wall.

  • Risk and coverage survey, camera type selection, lens and mounting strategy.
  • IP camera, NVR or VMS architecture, control rooms, remote access and health monitoring.
  • Storage and retention sizing based on camera count, resolution, frame rate, codec, motion and policy.
  • Network, PoE, fibre, UPS, time synchronisation and security design for CCTV infrastructure.
  • Audits, upgrades, migration from legacy systems and preventive maintenance.
  • Analytics such as ANPR or intelligent detection only where accuracy, privacy and environment are assessed.

How this is calculated

Storage = bitrate × recorded seconds per day × retention days × cameras. Capacities are decimal TB, as drives are sold.

Default bitrates are typical good-quality figures at 25 fps, moderate scene, H.264: 2MP 4 Mbps, 4MP 6 Mbps, 5MP 7 Mbps, 8MP 12 Mbps, 12MP 16 Mbps. H.265 halves this; smart codecs reduce it to about 30%. Busy scenes add 50%, quiet ones save 40%. Lower frame rates save less than proportionally, because most bits go into changes between frames.

Bitrate varies by camera, settings, lighting and scene. Enter the figure from the camera’s datasheet or recorder for an exact result.

RAID 5 needs at least 3 drives, RAID 6 at least 4. Recorders also have drive-bay and bandwidth limits; we size those on the survey.

Standards and terms

Standards we design to, and the terms you will hear

Specifications are written against recognised standards. Here is the vocabulary, in plain language.

  • IEC 62676 (video surveillance systems)
  • IEC 62676-4 (DORI pixel density)
  • EN 50132 (CCTV alarm systems)
  • ONVIF Profiles S, T, G, M, Q, A, C
  • IEC 60529 (IP ratings)
  • IEC 62262 (IK impact ratings)
  • IEEE 802.3af, 802.3at, 802.3bt (PoE)
  • TIA-568 and ISO/IEC 11801 (cabling)
  • BIS and STQC (Indian camera safety and security testing)
  • ISO/IEC 27001 aligned operating practices
  • H.264, H.265 and MJPEG video coding
  • RAID levels 1, 5, 6, 10
  • ATEX and IECEx for hazardous areas
  • IEC 61000 (EMC and surge immunity)
DORI
Detect, Observe, Recognise, Identify: the four levels of usable detail in IEC 62676-4, set by pixels per metre on the target. About 25, 63, 125 and 250 px/m.
Pixel density
How many pixels cover each metre of the scene at a given distance. It, not the megapixel count, decides whether a face or plate is readable.
WDR
Wide dynamic range. Lets a camera hold detail in both a bright doorway and a dark lobby in the same frame.
BLC / HLC
Backlight and highlight compensation. Stops headlights or windows from blanking the rest of the image.
Bitrate
The video data a camera sends each second. It drives network sizing and storage, and rises with resolution, frame rate and scene motion.
H.265 / H.265+
Compression standards that cut bitrate roughly in half compared with H.264 at similar quality, saving storage and bandwidth.
NVR / DVR / HVR
Network, digital and hybrid video recorders. NVRs record IP cameras; DVRs record analog; hybrids record both.
VMS
Video management software: the platform that connects cameras, recorders, users, alarms and maps.
ONVIF
An industry standard that lets cameras and software from different makers work together.
ANPR / LPR
Automatic number-plate recognition. Reads vehicle plates for logging, access control and watchlists.
PoE budget
The total power a PoE switch can supply across all ports. Exceed it and cameras drop out.
ANR
Automatic network replenishment: cameras store video locally during an outage and send it back when the link returns.
RAID
Disk arrangements that keep recording if a drive fails, trading some capacity for resilience.
Retention
How many days of footage are kept before it is overwritten. A business and legal decision that sizes the storage.
SOP and SLA
The standard operating procedures for how issues are handled, and the service levels agreed for response and restoration.

Questions

Frequently asked questions

Retention is a design decision, sized from camera count, resolution, frame rate, codec and motion activity against your required retention policy — not left to whatever the default hardware provides.

Through a physical coverage survey of the site, mapping fields of view against entry points, high-value areas and known risk zones.

Where condition and specification allow, yes — the survey identifies what can be retained and what needs replacing rather than assuming a full rip-and-replace.

Through authenticated, encrypted remote-access design rather than exposing NVR or camera interfaces directly to the internet.

Health monitoring is set up to flag failures early, and preventive maintenance visits catch degrading hardware before it causes a full outage.
