These turret cameras solve three different viewing problems. DS-2CD2387G2P-LSU/SL uses dual 4 mm lenses for a 180° panoramic image. DS-2CD2387G2-LSU/SL provides a conventional 8 MP fixed view with ColorVu, strobe, and two-way audio. DS-2CD2H86G2-IZS uses a 2.8–12 mm motorized lens, IR, and an IK10 housing for adjustable target framing.

| Night imaging | ColorVu with light, up to 30 m | ColorVu with white light, up to 30 m | IR, up to 40 m |
| WDR | 130 dB | 130 dB | 120 dB |
| Audio and warning | Built-in microphone and speaker; strobe and audio alarm | Built-in two-way audio; strobe and audio alarm | Audio and alarm interfaces |
| Protection | IP67 | IP67 | IP66, IK10 |
| Best-fit task | Continuous wide-area overview | Detailed fixed view with local warning | Adjustable framing with IR and stronger impact protection |
The panoramic model is marketed in the 8 MP class, but its frame geometry is 5120 × 1440 rather than conventional 3840 × 2160 4K. Compare pixel density at the actual target, not the marketing resolution alone.
DS-2CD2387G2P-LSU/SL: 180° panoramic overview
DS-2CD2387G2P-LSU/SL combines two 4 mm lenses into a 5120 × 1440 panoramic image with approximately 180° horizontal and 44° vertical coverage. It is designed for entrances, courtyards, loading areas, intersections, and other scenes where a continuous wide view can reduce blind zones.
The camera provides ColorVu imaging, light specified up to 30 m, 130 dB WDR, human/vehicle classification for supported events, a built-in microphone and speaker, and active strobe and audio warning. Its enclosure is IP67.
Panoramic width spreads pixels across a large scene. A target at distance may receive fewer pixels than it would in a narrower conventional view. Pair the panorama with a focused camera when identification or plate detail is required.
Frame rate also deserves attention. The current specification lists 5120 × 1440 at 12.5 fps for 50 Hz or 15 fps for 60 Hz when WDR is enabled, and up to 20 fps when WDR is disabled. Confirm whether that suits the expected movement.
Review the official DS-2CD2387G2P-LSU/SL data sheet for stitching, streams, audio, alarms, and environmental specifications.

DS-2CD2387G2-LSU/SL: fixed 8 MP view with active warning
DS-2CD2387G2-LSU/SL produces a conventional 3840 × 2160 image and uses a fixed 2.8 or 4 mm lens. It provides ColorVu imaging, white supplemental light up to 30 m, 130 dB WDR, human/vehicle classification, a built-in microphone and speaker, strobe light, audible warning, and audio/alarm interfaces.
This model suits a fixed entrance, yard, gate, or approach lane where local deterrence and two-way communication are part of the response design. The warning schedule, duration, volume, light behavior, event verification, and nuisance-alarm controls should be approved before activation.

DS-2CD2H86G2-IZS: motorized varifocal IR coverage
DS-2CD2H86G2-IZS provides 3840 × 2160 output and a 2.8–12 mm motorized lens with approximately 108° to 46° horizontal coverage. It uses IR specified up to 40 m, 120 dB WDR, and human/vehicle classification for supported events.
The camera offers audio and alarm interfaces, IP66 ingress protection, and IK10 impact protection. It is the relevant option when the installer needs to adjust target framing after mounting, visible white light is undesirable, or the site requires the stronger published impact rating.
Audio interfaces do not mean the camera has the same built-in speaker and microphone as the two LSU/SL models. Plan external devices and wiring where audio is required.

How to choose
- Choose DS-2CD2387G2P-LSU/SL when one continuous 180° overview is the primary goal.
- Choose DS-2CD2387G2-LSU/SL for a conventional 8 MP fixed view with built-in two-way audio and active warning.
- Choose DS-2CD2H86G2-IZS for motorized target framing, IR night imaging, and IK10 impact protection.
Deployment checklist
- Define overview, recognition, identification, and response goals separately.
- Calculate pixel density across the full panorama or fixed target width.
- Decide whether white light, IR, strobe, and audible warning are acceptable.
- Confirm frame rate with WDR enabled for moving targets.
- Check PoE power, speaker use, audio policy, alarm I/O, and network bandwidth.
- Verify NVR support for resolution, aspect ratio, analytics, audio, and event search.
- Test stitching, glare, movement, reflections, rain, and night evidence at the real site.
Frequently asked questions
Which model has the widest view?
DS-2CD2387G2P-LSU/SL, with approximately 180° horizontal coverage from two 4 mm lenses.
Which model has a motorized lens?
DS-2CD2H86G2-IZS. Its 2.8–12 mm lens allows remote framing adjustment within the fixed camera direction.
Do all three provide built-in two-way audio?
No. The two LSU/SL models list built-in microphone and speaker functions. DS-2CD2H86G2-IZS provides audio interfaces and may require external audio devices.
Is 5120 × 1440 the same as 4K UHD?
No. It is a wider panoramic format. Conventional 4K UHD is 3840 × 2160. Compare aspect ratio, frame rate, NVR support, and pixels on target.
