H.264 Baseline, Main or High Profile; H.265 Main Profile.

Bitrate control

CBR or VBR

Listed security controls

Password protection and complexity, watermark, HTTP basic/digest authentication, security audit log and MAC host authentication are listed. This is not a security certification or a current-firmware assessment.

Simultaneous viewing reference

Up to six simultaneous live-view channels; not six camera inputs.

Integration references

ISAPI and SDK are listed. Verify the actual recorder/software combination; this does not mean a website or OS integration has been implemented.

Listed network protocols

TCP/IP, ICMP, DHCP, DNS, HTTP, RTP, RTSP, NTP, IGMP, UDP and QoS. Additional protocols are not established by this row.

User-account reference

Up to 32 users; administrator, operator and user levels.

Client reference

iVMS-4200 is listed. Confirm the supported version and actual system.

Legacy browser reference

The sheet lists IE 10/11 plug-in live view and local service for Chrome 57.0+ or Firefox 52.0+. This historical minimum list is not a current browser-security recommendation or a plug-in-free compatibility guarantee.

Image, interface and events

Dynamic range

Digital WDR; no numeric true-WDR rating is established by this row.

Day/night modes

Day, night, auto or schedule.

Image enhancement

BLC, HLC and 3D DNR.

Image adjustment

Saturation, brightness, contrast, sharpness, gain and white balance are adjustable through the client software or web browser.

Ethernet interface

One self-adaptive RJ45 10/100 Mbps Ethernet port.

Basic events

Motion detection and exception events. Human/vehicle classification and face recognition are not established by this event row.

Event linkage reference

Surveillance-centre notification is listed. Actual delivery and system configuration require testing.

Power, environment and mounting

DC power reference

12 VDC ±25%, 0.41 A, maximum 5 W; 5.5 mm coaxial plug with reverse-polarity protection.

PoE power reference

IEEE 802.3af Class 3, maximum 6.5 W. This is an alternative to DC, not an added power requirement.

Housing material

Plastic

Overall dimensions

138.8 × 60.9 × 57.9 mm; allow separate mounting and cable clearance.

Package dimensions

163 × 75 × 75 mm; package contents require separate confirmation.

Storage and operating conditions

-30 to 60 °C; relative humidity at most 95%, non-condensing.

Listed interface languages

English and Ukrainian. Confirm the actual supplied firmware/language configuration.

General functions

Heartbeat, anti-banding, mirror, password protection and password reset via email are listed. This is not an ISD customer-message delivery claim.

Ingress-protection reference

IP67 is listed against IEC 60529-2013. Confirm mounting and sealing; this is not an impact or corrosion rating.

Corrosion selection

No specific anti-corrosion protection is assigned to this model. The generic top-level and moderate examples are not this model rating.

Mounting accessories

Optional DS-1276ZJ-SUS, DS-1280ZJ-XS and DS-1275ZJ-SUS are illustrated. Confirm the full mounting combination; accessories are not assumed included.

Mounting combinations

Corner: DS-1276ZJ-SUS + DS-1280ZJ-XS; junction box: DS-1280ZJ-XS; vertical pole: DS-1275ZJ-SUS + DS-1280ZJ-XS. Confirm the selected assembly and fixings.

Selection notes

• The cited datasheet lists multiple complete ordering codes. Match the full code; other versions are not merged or automatically approved.
• These details apply to IPC-B121H-C non-(B), non-CKD configuration only. Confirm the selected lens and supplied hardware/firmware; other complete ordering codes require separate confirmation.
• Lens-specific FOV and DORI values apply only to the selected lens. DORI and IR-distance figures are planning references, not identification or scene-coverage guarantees.
• Keep the full -C model. (B), CKD and other complete ordering versions are not interchangeable or automatically approved.
• The sheet does not establish audio pickup, a speaker, on-board recording, human/vehicle classification or a verified third-party integration for this selection.
• Digital WDR is not a numeric true-WDR claim. IP67 does not establish IK impact resistance, marine/coastal or chemical-corrosion suitability.
• Use currently supported recorder/client software and firmware. Historical browser minimums are not security recommendations.
• ISD supplies products only. Confirm stock, price, lead time, local warranty, actual package and supplied configuration separately.
