By Yogesh SagaleIP or analog CCTV should be selected based on the site, not only on the camera box price. For new societies, offices and commercial buildings, IP CCTV is usually the better long-term choice. If good coax cable already exists and the client only needs local monitoring from the security cabin, HD analog CCTV can still be a practical option.

“IP better or analog better?” is the wrong first question. The right question is: what does this site need to see, how far is the rack, is there already cable in the wall, and who will pull footage six months later?

Both systems record video. They do not behave the same on a society gate, a shop, a warehouse or an office floor. Analog today is mostly HD-over-coax. IP is a network camera. Pick the one that matches the building, not the one a quotation pushed because the margin was higher.

Short answer

• Existing coax, small site, budget tight, guard watches a local screen: HD analog, such as TVI, CVI or AHD, is often the practical choice.
• New building, society, office, commercial site, remote viewing, face or number-plate clarity, future cameras: IP is the better system.
• Old analog cameras already on coax and client will not recable: stay on HD analog or use a hybrid recorder. Do not rip out good coax just for fashion.

For most new APYS sites — societies, offices, commercial buildings — IP is the system we design, because cabling, rack, remote access and the next phase all sit on one network.

What “analog” means now

Old analog CCTV was CVBS: one camera, one coax, a DVR, and a soft 700-line picture. Current analog on live sites is mostly HD-over-coax: HD-TVI, HD-CVI and AHD. These send 2 MP, 4 MP and sometimes 5 MP or 8 MP video down RG59 or RG6 coax into a DVR. Power is usually a separate 12 V line, or a siamese cable with coax plus power.

HD analog can work well when coax is already pulled and healthy. It is simple for local viewing on a monitor in the security cabin and it needs less network skill for a basic install. But every camera still needs its path back toward the DVR, power and video are separate problems, analytics stay limited, and remote viewing depends entirely on the DVR.

If a quotation says “analog” and does not name TVI, CVI or AHD and the megapixel class, ask. A 2 MP HD analog camera and a 20-year-old CVBS camera are not the same product.

What an IP camera actually is

An IP camera is a network device. It compresses video on the camera and sends it over Cat6, fiber, or sometimes WiFi, into an NVR or VMS. Power is usually PoE from a switch, so one cable carries data and power.

IP gives practical 2 MP, 4 MP and 8 MP images, better lenses and wider dynamic range on good camera bodies, PoE cabling, labelled patch panels, spare switch ports for future cameras, ONVIF compatibility if specified, and stronger options for remote viewing, user rights, playback and analytics.

But IP also demands a real network design: cable length, switch, rack, UPS, earthing, storage, passwords and proper handover. IP is not “plug a camera into the office WiFi router.” That shortcut is how footage disappears.

Side-by-side comparison

Point	HD analog (TVI / CVI / AHD)	IP
Cable	Coax, usually RG59 / RG6, plus power	Cat6 / Cat6A, or fiber for long runs
Power	Separate 12 V supply	PoE from switch, one cable
Recorder	DVR	NVR
Typical clarity	2 MP common, 4 MP available	2 MP, 4 MP, 8 MP routine
Best use	Retrofit on existing coax, small local system	New societies, offices, commercial, multi-gate
Adding cameras later	New home-run coax	Spare port and a new outlet
Remote viewing	Only through the DVR	NVR, app and user rights
Analytics	Limited	Available if specified, not automatic
Cyber risk	Lower only if DVR is not exposed	Real if passwords and ports are ignored
Upgrade path	Ends at that coax standard	Same cabling can take a better camera later

Image quality: megapixels are not the whole story

A 4 MP analog camera does not automatically beat a 2 MP IP camera. Lens, mounting height, WDR, night performance, frame rate, bitrate and compression decide whether the footage is usable.

• A wide camera on a high pole will not read a face at the society gate.
• Lobbies and gates need WDR because of strong backlight.
• IR range on the box is a lab number; gate depth, wall colour and rain change it.
• Number plates need enough frames and the right angle.
• A starved IP stream can look worse than a clean 2 MP analog picture.

For a society main gate and office reception, design the view first: face at entry, plate at the lane, door in the lobby. Then pick IP or analog. Do not start from “8 MP” on a quotation.

Cabling, distance and power

Analog coax runs are simple until they are not. A long, damaged or poorly crimped RG59 run drops the picture. Power drop on a thin 12 V line makes night IR weak. Every camera still needs a path home.

IP over Cat6 has a practical channel limit near 90 to 100 metres. Beyond that, use a mid-span switch, a fiber pair, or a different topology. PoE removes the separate power supply, which is the failure point on many analog gates we are called to repair.

Monsoon rule for both: outdoor junctions need proper boxes and drip loops. IP cameras also need surge thinking on long outdoor copper. A camera that works in May and dies in July is usually a joint or a power issue, not a brand issue.

Recording, storage and playback

Analog recording lives on the DVR hard disk. IP recording lives on the NVR disk. The method is the same: resolution, frames, compression and retention decide the disk, not the sticker on the box.

A 4 TB disk is not a design. Thirty days of 4 MP cameras at a high bitrate will not fit where fifteen days of 2 MP might. Playback is where sites feel the difference. A guard needs last night’s gate clip in under a minute. An admin needs the same clip on a laptop without standing in the cabin. IP NVRs, set up with named cameras and user logins, usually do this more cleanly.

Remote viewing and security

Both can be viewed on a phone. The difference is how safely and how stably. A cloud P2P login on a cheap DVR or NVR is convenient, but weak passwords and open ports expose the site. For an office or a society, remote access should be a chosen method: recorder app with a strong password, proper user list, and no default ports left open to the world.

• Default passwords removed
• Operator login separate from admin
• Recorder not left open to the world without a reason
• Camera list and passwords handed over in writing
• Guest WiFi separated from camera and office networks

Scalability and the next phase

Societies add a second lane, a basement, a terrace door. Offices add a floor or a server room. This is where analog hurts. Each new analog camera is another coax and another power feed back to a DVR that may already be full. Each new IP camera is a port, a labelled outlet and a disk check.

If the building is new, pull Cat6. Do not pull coax “to save money” and then pay for a second route when the client asks for remote viewing.

Analytics, alerts and integration

Human and vehicle detection, line crossing, face capture and number-plate capture are IP features. They are not free because the camera is IP. They need the right camera, the right NVR or VMS, and a view that can actually see the target.

Analog DVRs can do basic motion, but motion on a society gate at night is mostly trees, rain and headlights. Integration also sits with IP more naturally: camera events beside access control, a barrier lane beside the plate view, attendance beside the lobby camera.

Cost: do not compare only the camera price

Analog looks cheaper on the camera line. The full cost includes coax, power supplies, power cable, DVR, disk, monitor and the day lost when a 12 V adapter fails.

IP looks higher on the camera line. The full cost includes Cat6, a PoE switch, patch panel, NVR, disk, rack and a UPS that also keeps the switch alive. On a new site with networking already in scope, the gap narrows, because the pathway is shared.

The expensive system is the one that is replaced in eighteen months because faces are not visible and the client cannot pull footage.

When analog is the better fit

• Healthy coax is already in place and the client will not recable.
• The system is small: a shop, a small godown, or a single gate with local monitoring only.
• Nobody needs reliable remote viewing or analytics.
• Budget is the constraint and the picture quality required is modest.
• The DVR can be replaced later without a civil job.

Analog is a valid scope. Pretending it is “same as IP” is not.

When IP is the better fit

• The building is new, or ceilings and routes are still open.
• It is a society, office, school, clinic, warehouse or commercial site.
• The gate must show a face or a plate, not just movement.
• More than one person must view or export footage.
• Cameras will be added in phase two.
• Access control, barrier, WiFi or structured cabling is already in the job.
• The client wants one rack, labels and a proper test handover.

This is the default for new APYS ELV work.

Hybrid sites

Some sites are mixed. Old floors on coax, new gate on IP. A hybrid recorder can take both, for a while. Use hybrid as a bridge, not as the design for a new building. Document which cameras are analog and which are IP. Do not leave the next vendor to discover it with a toner.

WiFi cameras are a third option, not a substitute for either on a permanent gate or perimeter. They fit a temporary view or a place where no cable can be pulled. They drop when the WiFi drops.

Common mistakes on both sides

• Buying 8 MP cameras and recording them at a bitrate that looks like 1 MP
• Mounting the gate camera too high and too wide
• No UPS on the recorder, or UPS on the DVR but not on the PoE switch
• Analog power run on thin wire, so IR fails at night
• IP cameras dumped on the office WiFi router
• No labels, so “Camera 7” on the app is not the basement door
• Retention never calculated
• Default passwords left in place
• No as-built, so the next fault is a search

What to freeze before ordering

1. Views that matter: gate face, plate, lobby, basement, server room, terrace.
2. Days of recording.
3. Who watches: cabin, admin, phone.
4. New cable or existing coax.
5. Hours of backup when mains fails.
6. Phase-two cameras, so spare ports or spare conduits exist.

APYS recommendation

For a new society, office or commercial building, design IP: Cat6, PoE, a dressed rack, named cameras, calculated storage, and a handover the guard can use. For a small retrofit on live coax, HD analog is still the honest option — specified as TVI, CVI or AHD, not as a vague “analog CCTV.”

APYS Projects handles both, including the pathway, the rack and the handover, as part of ELV and networking work.
