CCTV Installation in Bhiwadi

Most Bhiwadi factory enquiries start with a budget rather than a resolution. The honest answer is that both HDCVI/analog and IP systems are still viable in 2026, and the right choice depends on your cabling more than your camera preference.

Analog HD systems send video over RG-59 coaxial cable to a DVR. They are cheaper per channel, tolerate long cable runs without active equipment, and are a sensible retrofit when a site already has coax in the walls. The ceiling is real though: you are limited to roughly 5 MP, there is no useful on-camera analytics, and every camera needs a home run back to the DVR.

IP systems run Cat6 to a PoE switch and give you higher resolution, on-camera motion classification, and the ability to put a switch in each shed rather than pulling forty cables to one room. The practical constraint is the 100-metre Ethernet limit per segment. On a large plot that means distribution switches in weatherproof enclosures, which adds cost but usually less than the cable it saves.

For a greenfield factory we default to IP. For a running unit with existing coax and no appetite for shutdown, HD-over-coax upgrades often deliver more improvement per rupee.

Undersized storage is the single most common fault we find on systems installed by others. A site is sold '30 day recording' and discovers at the worst possible moment that it is overwriting after nine.

The arithmetic is not complicated. A 4 MP camera encoding H.265 at 15 fps averages roughly 2-3 Mbps depending on how much motion is in frame. That works out to about 25-30 GB per camera per day of continuous recording. Sixteen such cameras recording continuously for thirty days therefore needs on the order of 12-14 TB of usable disk, before any RAID overhead.

There are three levers. Drop to motion-triggered recording on low-traffic views and you can cut consumption substantially, though you accept gaps. Reduce frame rate on static areas such as store rooms, where 7 fps is genuinely sufficient. Or accept a shorter retention window on some channels and keep the full thirty days only on gates, cash handling points and dispatch.

We specify surveillance-rated drives, not desktop drives. A recorder writing continuously from sixteen cameras is a far harsher duty cycle than a PC, and consumer drives fail early under it.

Every gate specification we receive asks for number-plate capture. Most standard cameras will not deliver it at night, and it is worth understanding why before you sign a BOQ.

A general-purpose camera at night uses a slow shutter and infrared illumination to produce a bright, usable image of a scene. A moving number plate under those settings blurs into an unreadable white rectangle, made worse by the retroreflective plate surface bouncing IR straight back at the sensor.

Capturing plates reliably needs a camera configured for the job: fast shutter, tight zoom on a single lane, and dedicated illumination. The image looks dark and unhelpful to a human watching the live view, because it is optimised to expose the plate and nothing else. If you want both an overview of the gate and readable plates, that is two cameras, not one.

We will say so at survey stage rather than after handover. The same logic applies to reception desks and weighbridges, where a wide view and a face-identification view are different jobs.
