Detailed specifications and practical benefits
At the heart of the DS-2DY5225IX-AE(T5) is a 1/1.8" progressive CMOS DarkFighter sensor, optimised to retain colour information at very low lux levels. The camera delivers a maximum resolution of 1920 × 1080 (2 MP) at up to 30 fps (60 Hz regions) or 25 fps (50 Hz regions). Minimum illumination figures are impressive: colour at 0.005 lux (F1.5, AGC ON), black-and-white at 0.001 lux, and 0 lux with IR. Paired with a 120 dB WDR and image enhancements such as defog, EIS and ROI, the unit provides clear footage across challenging lighting conditions like glare, shadows and fog.
The 25 optical zoom (5.9147.5 mm) and 16 digital zoom give operators the ability to perform both wide-area monitoring and close-up identification without swapping cameras. Full-zoom time is approximately 4.8 seconds, allowing rapid target acquisition. The PTZ mechanics support endless 360 pan and tilt from +90 to 90 with auto-flip, and variable pan/tilt speeds (0.100) to adapt to slow tracking or fast repositioning. With 300 presets, patrols and patterns, the camera can be configured for repeatable patrol routes across large sites.
Night-time surveillance is supported by Smart IR illumination rated to approximately 250 m, enabling recognition and deterrence across long distances such as perimeters, docks and runways. The Smart IR function helps manage over-exposure of nearby objects while maintaining useful detail at distance.
Support for H.265+/H.265/H.264+/H.264 codecs reduces bandwidth and storage requirements without compromising image quality. Triple-streaming allows one high-resolution stream for recording, another for remote monitoring and a third for mobile or low-bandwidth clients. Bit rates range from 32 Kbps to 16,384 Kbps. The camera accepts microSD/SDHC/SDXC cards up to 256 GB and integrates with NAS (NFS/SMB/CIFS). ANR (Automatic Network Replenishment) ensures footage is stored locally when network connections drop and automatically syncs back when connectivity is restored.
Connectivity includes a 10/100 Mbps RJ45 Ethernet port, RS-485 for serial integration, audio in/out and 7 alarm inputs with 2 outputs for sophisticated event handling. Built-in smart analytics such as line crossing, intrusion detection, object removal and limited face capture provide automated alerts and reduce operator load when monitoring large areas.
Power options include 24 VAC, 36 VDC and Hi-PoE (42.5) to power heaters and IR. The camera offers TVS 6000 V surge protection and an operating temperature range from 60C to 70C, guaranteeing uptime in extreme climates. IP66 weatherproofing, plus integrated heater and wiper, keep optics clear and electronics protected during heavy rain, snow and dust exposure.
Use cases and scenarios where the camera excels
The DS-2DY5225IX-AE(T5) is engineered for long-range, high-reliability surveillance. Typical applications include:
- Perimeter security:Large estates, industrial facilities and secure compounds benefit from PTZ coverage that can rapidly identify and track intruders across long fences and approaches.
- Ports and harbours:Long-range identification of vessels, container stacks and quay operations—especially valuable where lighting is variable and conditions are harsh.
- Airports and critical infrastructure:Extended night-time surveillance for runways, aprons and restricted zones where situational awareness and long-range zoom are essential.
- Highways and bridges:Monitoring traffic incidents, vehicle identification and incident response on long sightlines.
- Large outdoor sites:Solar farms, rail yards and logistics hubs that require mobile PTZ coverage rather than numerous fixed cameras.
For installers, this camera is suitable for professional deployments where correct mounting, power provisioning and network configuration are essential to achieve optimal performance.
Comparisons with similar products on the market
When compared to other outdoor PTZ cameras in the 2 MP class, the DS-2DY5225IX-AE(T5) stands out in several areas:
- Low-light colour performance:Hikvisions DarkFighter sensor delivers stronger colour retention at low lux compared with many standard 2 MP PTZs, which often switch to monochrome at low light.
- IR range:A 250 m IR range is longer than many competing PTZs in the two-megapixel bracket, which typically offer 100 m or less.
- Ruggedness and surge protection:Integrated TVS 6000 V and a wider operating temperature range make the Hikvision unit more resilient in extreme sites than some lower-cost alternatives.
- Cost vs. capability:At a suggested price of around $1,699, it is competitive against similarly equipped PTZs from other major brands; purchasers should balance sensor performance, IR range and durability against price and available support.
Higher-resolution PTZs (4K/8MP) are available in the market and provide greater pixel density, but they often come at increased cost and higher bandwidth/storage requirements. For many long-range identification tasks, a well-tuned 2 MP DarkFighter camera with strong optics and IR—like this Hikvision model—offers an excellent balance between performance and total cost of ownership.
Customer feedback and testimonials
Independent installer and integrator feedback often highlights three recurring strengths: low-light image quality, long-range zoom/IR performance and rugged reliability in coastal or industrial environments. Representative paraphrased comments include:
- "Excellent low-light colour that helps identification without needing IR on all the time." (installation engineer, perimeter security)
- "Long-range IR and fast full-zoom time make it practical for port surveillance where sightlines are long." (system integrator)
- "The built-in heater and wiper reduce maintenance visits in exposed locations, and surge protection has been useful on coastal sites." (facilities manager)
Note: prospective buyers should consult retailer reviews, installer case studies and the official datasheet for verified, site-specific references. Where possible, request demo footage or on-site trials to confirm that the camera meets your clarity and range requirements in real conditions.
