CCTV Camera Specifications: A Complete Guide to Choosing the Right Camera in Nepal

01/11/2026 · CCTV Camera

CCTV camera specifications are the numbers on a spec sheet that describe how a camera sees, records and survives weather. Resolution shows picture detail, the lens sets the view, the night vision distance sets dark-hour coverage, the video encoder sets storage use, and the IP rating shows protection from dust and water.

A spec sheet can look like a wall of codes, yet each CCTV camera specification answers one plain question. Two cameras with the same megapixel label can behave very differently at night or in a Nepal monsoon, so read the lines that match your site.

This guide explains each line using the published spec tables of NV NightVision’s own cameras as examples. For the pixel side in more depth, see our CCTV resolution guide.

Quick summary

  • Match the megapixel count and lens angle to the area you want to cover.
  • Treat night vision distance as an ideal-case figure and test it at your own site.
  • Look for H.265 and an SD card limit if you want longer recording.
  • Check the IP rating for any camera that will face rain, and ask if none is listed.

Resolution and Quad HD Describe How Much Detail the Picture Holds

Resolution is the number of pixels in each frame, and a megapixel is about one million of them. Quad HD resolution usually means 2560 by 1440 pixels, which is about 3.7 million pixels and is often rounded up to 4MP.

The spec tables for the Ratri G11, T5P-Ratri Bullet, Y1-Ratri Dome and Netra V6Z list 4MP. The Netra S8 table lists 3MP, so read the number on the table and not the general marketing text on the page.

More pixels help you see a face or a number plate when you zoom in. They also create bigger video files, so a higher number needs more storage and a stronger Wi-Fi signal.

A CMOS Sensor and Aperture Decide How Much Light the Camera Gathers

A CMOS CCTV camera uses a chip that turns light into the picture. A larger chip and a wider lens opening gather more light, which helps at dusk and in poorly lit corners.

All five NV NightVision spec tables list a 1/2.8 inch CMOS sensor and a maximum aperture of F1.6. A smaller F number means a wider opening, so F1.6 lets in more light than F2.8 would.

Lens Size and Angle of View Set What the Camera Sees

The lens focal length controls how wide or narrow the view is. A smaller number shows a wider scene, and a larger number shows a narrower, more zoomed view.

The spec tables list a 4mm lens on the Ratri G11, T5P-Ratri Bullet, Y1-Ratri Dome and Netra V6Z, and a 3.6mm lens on the Netra S8. All five list a 104 degree angle of view.

Our guide to CCTV camera lens types explains when a wider or narrower lens suits a room, a gate or a long yard.

Night Vision Distance Tells You How Far the IR Lights Reach

Infrared lights let a camera see in the dark, and the night vision distance tells you how far they reach. All five NV NightVision spec tables list 8 to 10 meters.

Four of the tables list 8 infrared lights and 12 LED lights, and the Netra S8 table lists 6 infrared LEDs. Treat the distance as an ideal-case figure in clear air, because dust, glass and shiny walls can shorten it.

Our post on night vision versus infrared in CCTV explains how the two differ.

Frame Rate and 3D DNR Shape How Smooth and Clean the Video Looks

Frame rate is the number of pictures per second. All five spec tables list 20 frames per second, which is smooth enough to follow a person walking through a doorway.

DNR means digital noise reduction, and 3D DNR compares several frames to remove the grain that appears in low light. All five tables list 3D-NR support, which keeps night video cleaner.

The H.265 Encoder Cuts Storage Use for the Same Picture

The video encoder compresses the picture before it is saved or sent. An H.265 encoder is the newer standard, and the ITU-T lists H.265 as High efficiency video coding, with a January 2026 edition in force.

The spec tables for the Ratri G11, T5P-Ratri Bullet, Y1-Ratri Dome and Netra S8 list H.265. A good encoder means a memory card lasts longer and live view uses less data.

Storage, Wi-Fi and Power Lines Decide How the Camera Fits Your Home

Storage is the SD card limit. The Ratri G11, T5P-Ratri Bullet, Y1-Ratri Dome and Netra V6Z tables list a card of up to 256GB, and the Netra S8 table lists up to 128GB. No card is included with any of them.

All five list Wi-Fi to the IEEE 802.11b/g/n standard, a DC 5V 1A power supply and ONVIF support. Ask your recorder maker before you rely on ONVIF with a specific recorder.

Plug-in power means the camera stops when the supply does. Load shedding made that point clear for many Kathmandu families, so a small backup battery on the camera and the router is worth planning.

IP Ratings Show Dust and Water Protection and Nepal’s Monsoon Makes Them Matter

An IP rating has two digits. The first shows protection from dust and the second shows protection from water, and IP66 means the enclosure is dust-tight and resists powerful water jets.

myRepublica reported in June 2026, citing the Meteorological Forecasting Division, that the monsoon had reached Nepal from Koshi Province. The monsoon usually lasts until September, so an outdoor camera faces months of rain.

All five NV NightVision spec tables list an operating range of -20 to 50 degrees Celsius and 10 to 95 percent non-condensing humidity. None lists an IP rating, so ask before you mount any camera where rain can reach it.

Pan Range and Smart Features Are Spec Lines Too

Pan range is how far a camera turns left and right. The Ratri G11 table lists a 355 degree pan range, and the T5P-Ratri Bullet and Y1-Ratri Dome tables list 180 degrees. The Netra V6Z and Netra S8 show a fixed view.

All five tables list two-way audio, a built-in siren, human body detection, motion tracking and privacy mode. Our types of CCTV camera guide shows which shape suits which spot.

The CCTV Camera Specifications That Matter Most for a Nepal Home or Shop

Pick the lines by the job. For a front door, look at the angle of view and night vision distance. For a shop counter, look at the megapixel count and the storage limit.

For a compound with rain exposure, look at the IP rating first. For several cameras on one router, look at the encoder, because it decides how much data each stream uses.

Check the Spec Sheet Before You Buy and Again After You Install

A spec sheet is a promise in numbers. Read the CCTV camera specifications before you buy, then test each line at your own site, because walls, dust and Wi-Fi change what a number means in practice.

Here are your next steps:

The right camera is the one whose numbers fit your walls, your router and your weather.

Common Questions About CCTV Camera Specifications

What are the most important CCTV camera specifications?

Among all CCTV camera specifications, resolution, lens angle, night vision distance, video encoder, storage limit and IP rating matter most. Choose by the job: a door needs angle and night distance, a shop counter needs resolution and storage, and an outdoor wall needs an IP rating. Everything else is a bonus.

Is a higher megapixel number always better?

No. More pixels add detail but also create bigger files that need more storage and a stronger Wi-Fi signal. A 4MP picture is plenty for most doors and rooms. Lens angle, light gathering and night distance often decide if you can recognize a face.

What does H.265 mean on a camera spec sheet?

H.265 is a video encoding standard, formally titled High efficiency video coding. It compresses the picture more efficiently than older standards, so a memory card lasts longer and live view uses less data. Check that your phone app and recorder can play H.265 video.

What does an IP66 rating mean for a camera?

IP66 means the enclosure is dust-tight and resists powerful water jets. It is the kind of rating to look for on a camera that faces rain. If a spec table lists no IP rating, ask the seller about weather protection before you mount it outdoors.

How far can night vision on a spec sheet really see?

The listed figure is an ideal-case distance in clear air. Dust, glass, shiny walls and rain can shorten it. All five NV NightVision tables list 8 to 10 meters, so plan to cover a room or a gate and not a long yard, then test at night.

Where can I get help reading a spec sheet?

Ask a dealer to walk through the lines with the camera in hand. You can find an NV NightVision dealer near you and compare the spec tables before you buy. Bring a note of where you plan to mount the camera.
