Hikvision DS-2CD1021G0-I(4MM) – 2 MP Fixed Bullet Network Camera
The Hikvision DS-2CD1021G0-I(4MM) is a 2 MP fixed bullet network camera designed as a straightforward, budget-friendly entry point for basic surveillance. Specifically, it uses a 1/2.9″ progressive scan CMOS sensor paired with a fixed 4 mm lens, giving an 80° horizontal field of view and a detection range up to 55 m. As a result, it suits small shops, gates, and single-point coverage where advanced smart features aren’t required.
Illumination and Build
Furthermore, the camera includes a standard IR illuminator with a supplementary lighting range of up to 20 m, so it captures usable black-and-white footage after dark. Unlike the Smart Hybrid Light models in this catalog, it does not include white-light illumination, human/vehicle detection, or built-in audio — this is a simpler, budget-tier design. The housing carries an IP67 rating for dust and water resistance, and it operates across a -30°C to 60°C range.
Power and Storage Note
Either 12 VDC or PoE (IEEE 802.3af) can power it, making installation straightforward. Note that this model has no on-board microSD slot, so it depends entirely on an NVR or VMS for recording. Buyers who need local storage or smart detection features should consider a Smart Hybrid Light (G2) model instead.

Who This Camera Suits Best
- Budget-conscious NVR installations – its low cost and NVR-dependent recording suit buyers who already have centralised storage and don’t need smart detection.
- Small shops and single entry points – the 4 mm lens’s 55 m detection range fits gates, doorways, and small storefronts needing basic coverage.
- Straightforward PoE deployments – simple installation over a single Ethernet cable suits small offices or homes without complex requirements.
