D25 90M 3+1 CCTV Coaxial Cable — Complete Buyer's Guide for India

Setting up a CCTV security surveillance system in India — whether for your home, shop, office, or factory — starts with one decision that many buyers overlook: the quality of the cable connecting your cameras to your DVR or NVR. No matter how advanced your IP camera, AHD camera, or HD-TVI camera is, a poor-quality coaxial cable will degrade the video signal, introduce noise, and even cause complete signal loss over longer distances. The D25 Pure Copper 90 Metre 3+1 CCTV Coaxial Cable is engineered specifically to eliminate these problems — delivering stable, high-definition video, audio, and power transmission across your entire security network.

Why Cable Quality Defines Your CCTV System's Performance

In India, a large number of security camera installations suffer from grainy footage, colour bleeding, horizontal streaks on screen, or cameras that stop recording in the monsoon season. In the vast majority of these cases, the root cause is not the camera — it is the coaxial cable. A low-quality cable with a CCA (copper-clad aluminium) conductor instead of a genuine copper conductor loses signal strength rapidly as the cable run gets longer. By the time the signal travels 40 to 60 metres, it can be too weak for the DVR to decode properly, resulting in pixelated or black-and-white footage even from full HD cameras.

The D25 3+1 CCTV cable solves this problem at the source. Its 23 AWG solid copper center conductor maintains signal integrity over the full 90-metre length, ensuring that a camera installed at the far end of a large property delivers the same sharp, colour-accurate footage as one installed just a few metres from the recorder.

What Does 3+1 Mean in a CCTV Coaxial Cable?

If you are new to CCTV installations or purchasing cable for the first time, the term "3+1" can be confusing. Here is what it means in practice:

A standard coaxial cable (RG59 or RG6) carries only the video signal between your camera and DVR. However, CCTV cameras also need a power supply — typically 12V DC — and many cameras with microphones also need an audio signal path. Traditionally, installers had to run three separate cables: one coaxial for video, one twin-core wire for power, and one audio wire. This made installation messy, time-consuming, and expensive.

A 3+1 CCTV cable bundles all of these into a single sheathed cable: 1 RG59 coaxial core for HD video signal, 2 power wires (positive and negative for the 12V DC supply), and 1 audio/mic wire for microphone-equipped cameras. This all-in-one design dramatically simplifies installation because the electrician or CCTV technician only has to route a single cable from the camera location to the DVR, instead of three separate runs. The result is a cleaner, faster installation with fewer connection points and less risk of wiring errors.

Technical Construction: What Makes the D25 Cable Exceptional

Understanding the internal construction of a coaxial cable helps you evaluate whether it is suitable for your security system. The D25 cable is built with the following layers:

Center Conductor — 23 AWG Solid Copper: The innermost component carries the video signal. 23 AWG pure copper provides the ideal balance between flexibility and low resistance for CCTV applications. Thicker conductors (lower AWG) carry signals further with less loss — and the solid copper construction ensures the D25 cable maintains signal quality over the full 90-metre run without the degradation seen in thinner or CCA-based cables.

Dielectric Insulation — Foamed Polyethylene: Surrounding the copper core, the dielectric layer maintains consistent impedance (75 ohms for RG59) and reduces signal leakage. A high-quality dielectric is critical for stable video at HD resolutions such as 1080P, 4MP, 5MP, and 4K.

First Shield — Aluminium Foil: The first shielding layer is a bonded aluminium-mylar foil tape that covers 100% of the dielectric. This provides excellent protection against high-frequency RF interference — the type commonly generated by mobile towers, Wi-Fi routers, and electrical panels that are prevalent in Indian urban and industrial environments.

Second Shield — 95% Alloy Braiding: On top of the foil, a high-density 95% coverage alloy braid provides low-frequency EMI protection and structural strength. This dual-shielding system is what separates professional-grade CCTV cable from budget alternatives, which often use only a single thin braid with 40–60% coverage. The result is virtually noise-free video transmission even in electrically busy environments like factories, server rooms, and commercial markets.

Outer Jacket — UV-Resistant LLDPE: The outermost layer uses Linear Low-Density Polyethylene (LLDPE) — a premium outdoor-grade material that resists UV radiation, ozone, rain, extreme heat, and cold. In Indian conditions, where outdoor cables are exposed to intense monsoon rainfall, summer temperatures exceeding 45°C in many regions, and strong UV radiation, the quality of the outer jacket determines how long the cable lasts. Cheap PVC jackets become brittle and crack within two to three years when exposed to direct sunlight. The LLDPE jacket on the D25 cable maintains flexibility and integrity for many years of outdoor service.

Where to Use the D25 90M CCTV Cable in India

The D25 3+1 coaxial cable is an excellent choice for a wide range of security installations across India. Here are the most common applications:

Residential Homes: A typical 4 to 8 camera home CCTV system requires cable runs of 10 to 50 metres per camera. A single 90-metre roll is usually sufficient for a standard 2BHK or 3BHK installation, covering all entry points, the main gate, parking area, and common areas. The 3+1 design simplifies routing through walls and conduits.

Shops, Showrooms, and Retail Outlets: For small to medium retail outlets, the 90-metre roll provides enough cable to cover the full shop floor, billing counter, storage room, and entrance. The all-in-one 3+1 design keeps wiring neat — an important consideration in customer-facing environments.

Offices and Commercial Spaces: Corporate offices often require cable runs along false ceilings and through PVC conduit, where the flexible and slim profile of the D25 cable makes routing straightforward. The UV-resistant jacket also makes it suitable for exposed outdoor runs between buildings on a commercial campus.

Warehouses, Factories, and Industrial Facilities: These are among the most demanding environments for CCTV cable. The combination of long cable runs (often 40–80 metres), high ambient temperature, heavy electrical machinery generating EMI, and harsh industrial conditions makes the D25 cable an ideal choice — particularly its 95% braided shielding and LLDPE jacket.

Schools, Colleges, and Institutions: Educational institutions need reliable surveillance covering gates, corridors, classrooms, and parking areas. The D25 cable supports multi-camera installations with confidence that signal quality will be maintained across the entire campus network.

Petrol Pumps, ATMs, and Banks: High-security locations that operate 24x7 require cables with consistently low attenuation and strong shielding to prevent interference from electrical equipment. The D25 3+1 cable meets these requirements reliably.

Camera and DVR Compatibility — Full Details

One of the most important practical considerations when buying CCTV cable is ensuring it works with your camera technology. The D25 cable supports all current analog and HD over coax formats:

Analog CCTV (Traditional): Standard composite video cameras — whether CIF, D1, or 960H resolution — work perfectly with RG59 coaxial cable. The D25 cable is backward compatible with all legacy analog systems.

AHD (Analogue High Definition): AHD cameras (720P, 1080P, 5MP, 8MP) transmit HD video over standard coaxial cable. The 23 AWG copper conductor ensures minimal signal loss even at 5MP and 8MP resolutions.

HDCVI (High Definition Composite Video Interface): Dahua's HDCVI cameras at 1080P, 4MP, 5MP, 8MP, and 4K are all fully compatible with RG59 type cable. The D25 cable's low attenuation and strong shielding are essential for maintaining HDCVI signal quality over longer runs.

HD-TVI (High Definition Transport Video Interface): Hikvision and other HD-TVI cameras at resolutions up to 8MP and 4K operate perfectly on the D25 cable. The dual-shielding system is particularly beneficial for HD-TVI, which can be susceptible to interference in high-resolution modes.

HD-SDI: Professional-grade HD-SDI cameras and broadcast-quality security systems require high-quality RG59 cable with precise 75-ohm impedance — a specification met by the D25 cable's construction.

4K Ultra HD: Modern 4K security cameras (8MP and above) demand the lowest possible signal attenuation and the best possible shielding. The D25 cable's copper conductor and 95% braid make it suitable for 4K installations over appropriate distances.

How to Plan Your CCTV Cable Installation

Planning your cable runs before you begin installation will save you time, money, and frustration. Here are the key principles to follow when using the D25 90M 3+1 cable:

Measure all cable routes: Walk the route from each camera position to the DVR location, measuring the actual path the cable will take — not the straight-line distance. Add at least 1.5 to 2 metres per camera for connection loops, bending radius, and terminal connections at both ends.

Keep power cables away from AC lines: Wherever possible, run the D25 CCTV cable in a separate conduit from AC mains wiring. While the dual shielding provides strong EMI protection, physical separation from high-voltage AC lines remains best practice for professional installations.

Use appropriate conduit for outdoor runs: For outdoor installations, route the cable through UV-resistant PVC conduit whenever possible. Although the LLDPE jacket provides strong UV and weatherproofing protection, conduit adds an extra layer of mechanical protection against physical damage from tools, pests, or accidental impact.

Avoid sharp bends: Coaxial cable has a minimum bend radius — bending the cable too sharply can distort the dielectric and affect impedance. The D25 cable is designed to be flexible, but maintain a minimum bend radius of approximately 5 times the cable diameter (approximately 37mm) when routing around corners.

Label both ends: For multi-camera installations, label each cable run at both ends before connecting — this saves significant time during final termination and troubleshooting.

Buying CCTV Cable in India — Common Questions Answered

Is 90 metres enough for most installations? For residential homes and small commercial installations of 4 to 8 cameras, a single 90-metre roll is typically sufficient. Larger installations — factories, schools, multi-story commercial buildings — may require multiple rolls. WeKart offers bulk pricing for larger orders; contact us for a quote.

Can I use this cable with my existing power supply? Yes. The power cores in the 3+1 cable are designed for standard 12V DC CCTV power supplies. You can use a central multi-output power supply at the DVR end, running the positive and negative power wires within the same cable bundle as the video core.

Does the cable work with IP cameras? No. IP cameras use a Cat5e or Cat6 Ethernet cable (with PoE power), not coaxial cable. This D25 cable is designed for analog and HD over coax cameras — AHD, HDCVI, HD-TVI, HD-SDI, and standard analog — not for IP camera systems.

Is this cable suitable for direct underground burial? The LLDPE jacket provides good moisture resistance, but for true direct-burial installations (where the cable will be buried directly in soil without conduit), additional gel-filled or armoured cable is recommended. For wall-mounted, overhead, and conduit-routed outdoor runs, the LLDPE jacket is fully adequate.

What connectors do I need for installation? Each camera end and DVR end requires a BNC connector crimped or soldered onto the coaxial core, plus a DC barrel connector on the power wires. Compression-type BNC connectors are recommended for professional installations as they provide the most reliable and weatherproof termination. RCA connectors can also be used where BNC is not available.
