06Setup

Installation & setup

  1. Check power capacity

    Provide IEEE 802.3at PoE with capacity for 19W, or a suitable 12V DC supply.

  2. Set warning events

    Configure detection zones, target types and warning schedules for the site.

  3. Confirm recording support

    Choose recording equipment compatible with 12MP streams and the required camera events. Protect external cable connections.

08Questions

Frequently asked about the DS-2CD20126G3-IUY/SL

Q.01

Will this 12MP camera work with my existing NVR?
Check the NVR's supported camera resolution and incoming bandwidth, as well as its PoE budget. This model outputs 4608 × 2592 at 20fps and supports H.264/H.265, with a configurable video bitrate up to 20Mbps. In 50Hz mode, 4K and the listed lower resolutions run at up to 25fps. A recorder's channel count alone does not establish 12MP support.
Q.02

Can I use the same PoE port as a basic fixed camera?
Check the port specification first. This Liveguard model requires IEEE 802.3at PoE, Class 4, and can draw up to 19W. Its DC alternative is 12V DC +/-25%, up to 15.6W. Plan the per-port rating and total switch or NVR power budget for this model.
Q.03

Is the white light a warning strobe or continuous colour-night illumination?
This SL model has a white warning strobe and an audible alarm. Its specified night illuminator is infrared, up to 40m at 850nm. These are separate functions; the white warning light is not a specification for continuous full-colour night recording. Red and blue warning lights belong to the separately ordered SRB model.
Q.04

Does the camera provide both audio capture and an audible warning?
Yes. It has a built-in single microphone and a built-in speaker, specified at up to 2W. The microphone supports mono audio recording through a compatible setup, while the speaker provides the audible-warning function. Check the recorder or client support for the audio functions you intend to use.
Q.05

Can alerts focus on people and vehicles instead of every movement?
Yes. Motion detection and supported perimeter events can trigger on human or vehicle targets. The perimeter functions include line crossing, intrusion, region entrance and region exiting. Configure the target types and detection area for the scene; classification helps reduce unwanted alerts but does not promise that every false alarm will disappear.
Q.06

Which junction box is listed for this camera?
Hikvision lists the DS-1280ZJ-XS-Y junction box as an optional accessory. It also lists DS-1276ZJ-SUS for corner mounting and DS-1275ZJ-SUS for vertical pole mounting. Choose the accessory for the mounting surface and cable arrangement; these are separate accessories, not a statement of box contents.

Buying from Smarket

Is your Hikvision, Dahua, HiLook and TP-Link VIGI stock genuine Australian stock?

Yes, 100%. Every Hikvision, Dahua, HiLook and TP-Link VIGI product we sell is a genuine Australian-market model sourced through Australian supply chains — never grey imports. That means factory-sealed units, Australian-region firmware that works with the official apps out of the box, and a full 3-year local warranty.

How long does delivery take?

Metro delivery usually takes 2–4 business days after dispatch, and regional areas may take longer. You'll receive a tracking number by email as soon as your order leaves the warehouse.

How much is shipping?

Standard shipping is free on all orders over $300 AUD, Australia-wide. Orders under $300 ship at a flat rate of $25, calculated at checkout. Tracking is included on every order.

What warranty do you offer?

All cameras, NVRs and DVRs come with a 3-year back-to-base manufacturer warranty covering defects in materials and workmanship, in addition to your rights under Australian Consumer Law. Hard drives and accessories are covered as set out in our Warranty Policy.

What is your return policy?

You have 30 days from the day you receive your order to request a change-of-mind return. Items must be unopened, factory-sealed and in resalable condition. A 15% restocking fee applies and return postage is at your cost. Faulty or incorrectly supplied items are different: we cover the return shipping and refund or replace at no charge. Read the full Return & Refund Policy.

Do you offer installation?

We can connect you with licensed installers in Sydney and Melbourne. Installation typically starts from around $200 per camera depending on cable runs and site conditions. Email sales@smarket.com.au with your address and camera count for a quote.

Recommended packages

01

Recorder selection

Choose an 8CH M-Series NVR for a small system, or 16CH for more capacity. Start with 4TB for 1–2 cameras, 6TB–8TB for 3–4 cameras, or 8TB–10TB for 5–8 cameras; size storage for your required retention. These are starting capacities, not guaranteed recording days. The listed recorders support H.265/H.264 and IEEE 802.3af/at PoE. Options marked 4TB included already contain a hard drive; choose No HDD to add your own capacity. Recording inputs and simultaneous full-resolution playback are different limits.

02

Camera count and power

This camera is specified at up to 20Mbps and 19W over PoE. The configurator uses those maxima and reserves 10% of recorder PoE capacity. The 8CH M2 has 128Mbps incoming bandwidth and 120W PoE; the 16CH M2 has 256Mbps and 200W. More cameras may require adjusted bitrates or a separately powered design.

03

Storage planning

Use surveillance-grade SATA HDDs such as WD Purple or Seagate SkyHawk. At a constant 8Mbps per camera, 24/7 recording uses about 86.4GB per camera per day before overhead. Four cameras therefore need about 4.84TB for 14 days; eight need about 9.68TB. Actual retention changes with bitrate, motion, recording schedule and usable disk capacity. Hard drives install in the NVR, not the camera.

04

Cabling and mounting

Allow one correctly sized Ethernet cable per camera. The PoE recorder supplies camera power; a separate camera power adaptor is not required for that connection. DS-1280ZJ-XS-Y junction box; DS-1276ZJ-SUS corner mount; DS-1275ZJ-SUS vertical pole mount. Optional accessories are separately selected. Exact -Y junction-box and bracket versions are not currently linked for purchase; do not substitute a similarly named older mount.
