HIKVISION DS-2CD1021G0-I (2 MP/4 MM) - PoE IP CAMERA

A 4 mm lens for a somewhat greater distance at a simple price

DS-2CD1021G0-I differs from typical budget cameras with a 4 mm lens instead of the standard 2.8 mm — a narrower 94° field of view is compensated by better detail on subjects positioned somewhat further from the camera.

Where this camera is actually used

A plastic bullet housing with an IP67 rating and a -30°C to +60°C operating range fits well at a driveway, a small fence perimeter, or an entrance where the typical observation distance is somewhat greater than a room's.

What problem this camera actually solves

A standard wide 2.8 mm lens covers nearby space beautifully, but at 5-8 meters, details shrink. DS-2CD1021G0-I solves this with a narrower 4 mm lens at the same simple price as a base model — detail at a somewhat greater distance with no extra cost.

2 MP with a simple, dependable build

An extended -30°C to +60°C operating range — rare for such an affordable model — confirms readiness for demanding climate conditions even at this base price tier.

Only ISAPI and SDK — no ONVIF

Unlike most models in the lineup, this camera doesn't support the ONVIF protocol, only proprietary ISAPI and an SDK — worth checking compatibility with your existing NVR or software beforehand if your system specifically requires an ONVIF connection.

PoE and a microphone

PoE 802.3af power (6.5 W) means a single cable to the camera. A built-in microphone adds an audio track to every recording.

When to factor in protocol limitations upfront

If your surveillance system is built on a multi-vendor NVR requiring ONVIF, this model won't fit without additional verification — better to check compatibility before purchase than run into the problem after installation.

Stable operation all year round

A -30°C to +60°C operating range allows mounting where other electronics would need heating or extra protection in winter — an unheated corridor, an unheated storeroom, an outdoor canopy.

Predictable cost with no hidden markup

The lack of ONVIF support here isn't a result of cutting corners on components, but a deliberate choice by the manufacturer for the most affordable segment of the lineup — the owner pays specifically for base functionality, not for a protocol that might never be needed in practice.

A practical use case

A typical scenario for this model is a private home with Hikvision's own app, where the owner wants a clearer picture at the distance of an entrance gate without paying extra for third-party NVR compatibility that won't be needed in practice.

Simple installation with no special preparation

The bullet housing's standard mounting pattern lets you install this model in place of an aging camera without a new hole in the wall and without bringing in an additional narrowly-specialized installer.

Who this model is for

DS-2CD1021G0-I is the pick for an owner who needs a simple, dependable camera with a somewhat greater viewing distance at an affordable price, and who uses Hikvision's own software or a compatible NVR without an ONVIF requirement.
