Video and control

Frame-rate reference

50 Hz: 25 fps at 1920 × 1080; 60 Hz: 30 fps at 1920 × 1080 as listed. Confirm the selected signal format and compatible recorder; not an every-output-mode concurrency guarantee.

DVR control protocol

UTC protocol, or HIKVISION-C protocol in a previous DVR, is listed; confirm recorder compatibility. The source heading Network does not establish TCP/IP networking for this analogue camera.

Image settings

AGC and white balance are listed; confirm the required scene settings.

WDR reference

At least 120 dB WDR is listed; confirm scene and image configuration.

Image stabilisation

EIS is listed; confirm the intended scene and settings.

Image enhancement

BLC, HLC and 3D DNR are listed; confirm the actual exposure and noise-reduction settings.

Privacy masks

8 programmable privacy masks as listed; confirm the required masking configuration.

Regional focus

Regional focus is listed; confirm the intended focus-control setup.

Video output

Selectable TVI / AHD / CVI / CVBS output with BNC and NTSC/PAL composite reference as listed; confirm recorder format. This does not imply four simultaneous video outputs.

RS-485 control

Half-duplex RS-485 with self-adaptive HIKVISION, Pelco-P and Pelco-D protocols as listed; confirm controller/wiring. Half-duplex here is serial control, not an audio or talk feature.

Power and mounting

Power reference

12 V DC, maximum 20 W, with IR 7 W shown in parentheses as listed. Confirm actual supply sizing; do not treat the IR figure as a separate extra allowance or assume an included adapter.

Menu language

English as listed; confirm the actual firmware/menu language.

Protection reference

IP66 for the outdoor dome, TVS 4,000 V lightning protection, surge protection and voltage transient protection are listed. Correct installation and external protection remain necessary; this is not a direct-lightning guarantee.

Anti-corrosion reference

The manufacturer assigns no specific anti-corrosion protection to this model. IP66 must not be interpreted as a coastal or chemical-corrosion rating; confirm suitability separately.

Optional mount references

HIA-B473, HIA-B471-P, HIA-B172, HIA-B171, HIA-B471-B, HIA-B371, HIA-B471, HIA-B471-BP, HIA-B571, HIA-B173, HIA-B471-BC, HIA-B472 and HIA-B471-C are listed as optional references. Confirm the exact supplied hardware and accessory fit; not assumed included.

Selection notes

• Manufacturer references for the explicitly listed base PTZ-T4225I-D require confirmation of supplied hardware/firmware, analogue DVR compatibility, power, mounting and scene conditions.
• The cover and complete Available Model list explicitly name PTZ-T4225I-D; this reference uses only that unsuffixed model and does not declare other listed editions equivalent.
• Confirm the complete model, stock, price, ETA, supplied package and local warranty with ISD. Similar suffixes are not interchangeable.
• ISD supplies products only. Confirm mounting accessories, power, camera/recorder signal format and configuration separately.
• The cited source separately lists multiple hardware/branding editions. Confirm the actual supplied unit; the list is not a catalogue-model alias or approval to substitute.
• RS-485 half-duplex and UTC are control references. They do not establish audio, Ethernet, PoE or IP-streaming capability.
• IP66 and surge protection do not create a coastal-corrosion or direct-lightning guarantee. Confirm site conditions and mounting accessories.
