The IPC6828EL-X42-W-VH1 is an 8MP (3840×2160) PTZ dome camera with a 42× optical zoom lens (6.0-252mm, 16× digital zoom) and LightHunter low-light imaging (0.0005 Lux color, 0 Lux with IR). Auto tracking classifies and follows human, non-motor and motor-vehicle targets; smart intrusion prevention covers cross-line, intrusion, area-enter and area-leave detection with false-alarm classification filtering, and people-flow counting with crowd-density monitoring runs alongside. Pan is continuous 360° endless rotation, tilt runs -15° to 90° with auto flip, and the unit stores 1024 presets with 16 preset/route/recorded patrols. IR illumination reaches 500 m at 850 nm, gyroscope stabilization (EIS) steadies the image, and a wiper plus heater support the IP67 housing across a -40 °C to 70 °C working range.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Perimeter & long-range patrol42× optical zoom (6.0-252mm) reaches deep into a plant boundary or highway shoulder; smart intrusion prevention covers cross-line, intrusion, area-enter and area-leave detection with human/vehicle classification filtering to cut false alarms.
Auto-tracking on people & vehiclesAuto tracking classifies and follows human, non-motor and motor-vehicle targets automatically, so one operator doesn't need to manually pan-tilt-zoom to keep a moving target in frame.
Low-light & night operationLightHunter imaging keeps color detail down to 0.0005 Lux; once it's fully dark, 850 nm IR reaches 500 m so the zoom lens still has something to work with at range.
People counting & crowd densityBuilt-in people-flow counting and crowd-density monitoring run alongside the patrol/tracking functions — useful at gates, entrances or transit points without a separate analytics camera.
Rain, snow & dusty polesA wiper keeps the lens window clear in rain, and gyroscope stabilization (EIS) steadies the long-zoom image on a pole that sways in the wind — both useful where the camera can't be cleaned often.
Harsh outdoor & wide-temperature sitesIP67 sealing, a built-in heater and -40 °C to 70 °C operation cover cold-winter or hot-summer poles; 6 kV surge protection guards against lightning-prone lines.
Not the right pick if you need…
- No PoE listed on the datasheet — power is AC 24 V±25%, DC 24 V±25% or PoE (IEEE 802.3bt). If you plan a PoE-only run, confirm 802.3bt (PoE++) switch/injector support and max. 67 W budget before ordering.
- 6.9 kg, Ø226.7 mm × 440.3 mm: this is a full-size PTZ dome, not a light mini-PTZ — plan a mounting bracket and pole rated for the weight (bracket options listed below).
- The datasheet lists IR illumination only (850 nm, 500 m) — no separate laser or warm-light distance figure is given, despite the product name. If a confirmed laser-illuminator distance is required for your spec sheet, check with us before quoting.

How wide a view at each distance
Scene width covered at typical mounting distances — the number you need to work out how many cameras a wall, yard or aisle takes.

Calculated from the horizontal field of view in the specifications below: width = 2 × distance × tan(FOV ÷ 2). Lens distortion and mounting angle are not included.
Who uses it, where it goes and how to install it
Written for the IPC6828EL-X42-W-VH1 from its own datasheet: 8 MP (3840×2160) at 30 fps, 42x optical zoom (6.0–252 mm), 850 nm illumination up to 500 m, auto-tracking, wiper and gyroscope EIS, IP67, AC/DC 24 V or PoE IEEE 802.3bt (max. 67 W).
Who it is for
- Wide scenes that need detail at the wide end — 3840 pixels across a 57.96° view give about 69 pixels per metre at 50 m even without zooming, against about 47 for the 4 MP IPC6824EL-X42-W-VH1, so the overview itself is more useful as evidence.
- Plant boundaries, highways and ports — 42x zoom (6.0–252 mm) identifies a person up to 333.1 m in daylight; smart intrusion prevention with human/vehicle filtering raises the alarm and auto-tracking follows the target.
- Investigation-driven sites — Multi-target detection captures human body, motor and non-motor vehicle images with attributes, and best-snapshot selection keeps the clearest frame, so events can be searched later instead of watched live.
- Integrators with alarm panels and VMS — Alarm I/O 7/2, RS485 and audio I/O 1/1 for detectors, sirens and external speakers, plus ONVIF Profile S/G/T/M and the EZStation, UNV-Link and UNV-Link Pro clients.
Where and how to install
- Height, reach and tampering — Mount high, typically 6–10 m on a pole or tower. The housing is IP67 but no IK impact rating is listed, so keep it well out of reach and away from where stones or tools could hit the dome.
- A rigid mount for 6.9 kg at 252 mm — At 252 mm the view is only 2.15° wide. Use the pole brackets TR-UP08-A-IN or aluminium TR-UP08-B-IN on a thick, well-anchored pole, or the corner brackets TR-UC08-A-IN / TR-UC08-B-IN; on walls use TR-WE45-A-IN (long) or the gooseneck TR-WE45-B-IN, which move more in wind. Ceiling: TR-CE45-IN, TR-UF45-A-IN, TR-SE45-IN (200), TR-SE45-A-IN (500).
- Power: 24 V or 802.3bt PoE — Maximum draw is 67 W with heater, wiper and illuminator running. Use AC 24 V or DC 24 V (±25%) from a supply near the pole, or an IEEE 802.3bt PoE port able to deliver it; 802.3af/at (15.4/30 W) ports are not enough. Join the cold-pressed power wires, network and alarm wiring in the TR-JB12-IN junction box.
- Network run and surge — The port is 10/100 Mbps RJ45, copper up to 100 m per run; use fibre to a switch near the pole for longer runs. Surge protection is 6 kV; on towers add surge protectors on power and network at both ends and earth the structure.
- Keep the illumination path clear — Keep walls, eaves, railings and branches out of the wide-angle frame: 850 nm light reflects off close objects and washes out the night image. Run the wiper after rain or dust, and check every preset at night after installation.
Wide or zoomed in: what you actually see
At 6.0 mm the IPC6828EL-X42-W-VH1 covers about 55.4 m of width at 50 m. At 252 mm the view is about 1.9 m wide at 50 m and 3.8 m at 100 m, which puts roughly 1023 pixels on each metre of the scene at 100 m (3840 ÷ 3.75), about 1.5x the 4 MP sibling at the same distance. The 500 m illumination applies at full zoom and is shorter at wide angle.
| Wide · 6.0 mm | Tele · 252 mm | |
|---|---|---|
| Horizontal view angle | 57.96° | 2.15° |
| Width covered at 10 m | 11.1 m | 0.4 m |
| Width covered at 50 m | 55.4 m | 1.9 m |
| Width covered at 100 m | 110.8 m | 3.8 m |
| Pixels per metre at 50 m | 69 | 2046 |
| Identify a stranger's face up to | 10.7 m | 333.1 m |
| Recognize someone you know up to | 21.4 m | 666.1 m |
| See what a person is doing up to | 42.9 m | 1332.2 m |
| Detect that something is there up to | 107.2 m | 3330.6 m |
| IR night distance | < 500 m | 500 m |
- Use the wide end as a high-detail overview: at 50 m the 6.0 mm view covers 55.4 m with about 69 pixels per metre.
- Save tele presets on distant gates and fence corners: at 252 mm a person is identifiable up to 333.1 m in daylight.
- At night, distant presets must be zoomed in to get the full 500 m illumination reach.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per metre = 3840 ÷ width. Identify/recognize/observe/detect distances are the manufacturer's DORI figures (EN 62676-4) from the datasheet. Illumination range is proportional to the optical zoom; the datasheet gives it only at full zoom.

8MP 42x PTZ Camera FAQ — IPC6828EL-X42-W-VH1
How far can the IPC6828EL see at night?
Per the product data IR reaches 500 m, and the LightHunter 1/1.8-inch sensor works down to 0.0005 lux in color (F1.2, AGC on), 0 lux with IR. HLC and BLC tame headlights, and digital plus optical defog keep long-range views usable in haze.
What do 8MP and 42x zoom give me in practice?
The 6–252 mm lens covers 42x optical plus 16x digital zoom, recording 4K (3840x2160) at up to 30 fps. DORI figures at telephoto: detect 3330.6 m, observe 1332.2 m, recognize 666.1 m, identify 333.1 m — enough pixel density to read details at long range.
Does it follow moving targets automatically?
Yes. Auto tracking filters targets by human, vehicle and non-motor vehicle, with multi-target detection support. Smart intrusion prevention provides cross-line, intrusion and enter/leave-area detection with false alarm filtering, and people flow counting plus crowd density monitoring cover busy entrances.
Will the image shake on a tall pole in wind?
Gyroscope-based EIS compensates pole sway, which matters most at the 42x telephoto end where small movements look large. Ultra motion detection, tampering alarm and audio detection run alongside, and two-way audio (G.711U/G.711A) lets operators warn intruders directly.
What operating conditions is it rated for?
Per the product data it is IP67 rated and runs from -40 to 70 °C, covering desert daytime heat and highland cold. Bit rate is adjustable from 128 Kbps to 16 Mbps with Ultra 265 and U-code, keeping the 4K stream practical on site networks.
Can the IPC6828EL-X42-W-VH1 run on PoE, and which kind?
Yes, the datasheet lists PoE (IEEE 802.3bt) alongside AC 24 V and DC 24 V (±25%). Its maximum draw is 67 W, so under 802.3bt you need a Type 4 (class 8) port, which gives 90 W at the switch and about 71.3 W at the device; a Type 3 port (about 51 W at the device) or any 802.3af/at port is not enough. Keep the copper run within 100 m on Cat6, or use 24 V where no such port is available.
Does the IPC6828EL-X42-W-VH1 use a laser or normal IR, and is the night image in color?
The product name says laser, but the specification table lists 'Illumination Distance (IR) 500 m' at 850 nm, proportional to the optical zoom, without naming the light source; if your tender requires a laser illuminator, ask us to confirm before ordering. Either way it is infrared light, so when it switches on the image is black and white. LightHunter keeps color down to 0.0005 Lux (F1.2, AGC on) where there is some street or yard lighting.
IPC6828EL-X42-W-VH1 (8 MP) or IPC6824EL-X42-W-VH1 (4 MP): which should I buy?
Both use the same 6.0–252 mm 42x lens, 500 m night range, wiper, auto-tracking, alarm I/O 7/2, 67 W power and brackets, and the datasheets give them the same DORI distances. This 8 MP model has 3840×2160 at up to 30 fps, so a wide view or a partly zoomed preset holds about 1.5x more pixels per metre. The 4 MP IPC6824EL-X42-W-VH1 runs up to 60 fps, has slightly better low-light color (0.0003 Lux vs 0.0005 Lux) and adds IK10. Choose 8 MP for detail in wide scenes, 4 MP for fast traffic, vandal-prone sites or lower storage.
How much bandwidth and storage does the IPC6828EL-X42-W-VH1 need?
The bit rate is adjustable from 128 Kbps to 16 Mbps. Assuming 8 Mbps continuous recording for the 8 MP stream, one camera writes about 86.4 GB per day, about 2.6 TB for 30 days; at 16 Mbps about 5.2 TB. The camera port is 10/100 Mbps, which is enough for one camera, but 8 cameras at 16 Mbps add up to 128 Mbps, so use a gigabit uplink from the PoE switch to the NVR. Ultra 265 and event recording reduce both figures; the 512 GB microSD maximum holds about 5.9 days at 8 Mbps.
Will the IPC6828EL-X42-W-VH1 work with a Hikvision, Dahua or other third-party NVR?
Usually yes for live view, recording and PTZ control: it supports ONVIF Profile S, G, T and M plus RTSP. Check that the recorder accepts 3840×2160 streams on that channel; if not, record the 1080P sub stream. Auto-tracking runs inside the camera, so it works with any recorder, but intrusion events and multi-target attributes reach a third-party system only if it supports them. Tell us your NVR model and we will confirm before you order.
Is the IPC6828EL-X42-W-VH1 vandal-resistant?
No IK impact rating is listed for this model: its protection is IP67 against dust and water only, while the 4 MP IPC6824EL-X42-W-VH1 and IPC6824ER-X42-W-VH2 list IK10 (except the front window). In practice that matters little on a 6 m or higher pole, but where the dome can be reached or hit by thrown objects, mount it higher or choose an IK10 sibling.
