Hikvision DS-2CD3686G2HT-LIZS(Y) 8MP Smart Hybrid Motorised Bullet Camera with Darkfighter, Varifocal 2.7–13.5mm, IR 60m
The Hikvision DS-2CD3686G2HT-LIZS(Y) is an 8 MP (4K) motorised varifocal bullet camera built for demanding, exposed sites. A 2.7-13.5 mm motorised lens lets you set the field of view remotely, Smart Hybrid Light switches between infrared and white light for discreet or full-colour night images to 60 m, and AcuSense deep-learning analytics flag people and vehicles to cut false alarms. It is IP67, IK10 and carries a NEMA 4X anti-corrosion rating on the -Y model for coastal and industrial use.

§ 01Overview
What the DS-2CD3686G2HT-LIZS(Y) is
The Hikvision DS-2CD3686G2HT-LIZS(Y) is a premium 8 MP 4K bullet camera for sites where image quality and durability both matter.
Its 2.7-13.5 mm motorised varifocal lens means you can dial in exactly the field of view you need - a wide 112° overview or a tight long-range shot - from the software, without climbing back up to the camera.
At night it uses Smart Hybrid Light: it can stay in discreet infrared for black-and-white images, or switch on white light for full-colour footage, with supplementary lighting reaching up to 60 m.
130 dB true WDR keeps faces and number plates readable against headlights and bright backgrounds, and AcuSense deep-learning analytics classify human and vehicle targets so motion alarms and perimeter rules ignore animals, rain and swaying trees.
It is built to survive harsh locations.
The housing is IP67 against dust and heavy rain and IK10 against impact, and the -Y version adds a NEMA 4X anti-corrosion rating, which is what makes it suited to coastal, agricultural and industrial sites where salt and chemicals attack ordinary cameras.
Power it from PoE or 12 VDC and connect it to a Hikvision NVR for recording and AcuSense search.

§ 04Why choose this
Built for the way you actually use the DS-2CD3686G2HT-LIZS(Y)
Two ways to see at night
Smart Hybrid Light gives you discreet IR or full-colour white light to 60 m, so you choose detail or stealth scene by scene.
Fewer false alarms
AcuSense human and vehicle classification keeps alerts focused on people and cars, not animals or weather.
Survives harsh sites
IP67, IK10 and NEMA 4X anti-corrosion on the -Y model suit coastal, rural and industrial locations.
§ 05Where it fits
Right at home in these scenarios
Coastal and waterfront properties
NEMA 4X anti-corrosion stands up to salt air where ordinary cameras corrode.
Industrial and agricultural sites
Cover yards, sheds and laneways with a tough, long-range varifocal bullet.
Driveways and perimeters
Zoom in on the entry and use AcuSense rules to alert on people and vehicles only.
Car parks and forecourts
Read plates and faces across a wide area with 4K detail and WDR against headlights.
§ 06Setup
Installation & setup
What's in the box
One DS-2CD3686G2HT-LIZS(Y) 8MP motorised bullet camera with mounting template and fixings. Power supply, network cable and any NVR are supplied separately.
Installation requirements
Mount it on a wall or eave aimed at the area to cover, and power it from a PoE switch or NVR or a 12 VDC supply. Connect the network, then set the motorised zoom and focus, the day/night Smart Hybrid Light behaviour and the AcuSense perimeter rules in the software. Add it to a Hikvision NVR for recording and event search.
