Prama PT‑HTH112E‑ITF is a 5MP outdoor EXIR bullet camera for HD‑TVI, AHD, CVI, and CVBS systems. It uses a 5MP CMOS sensor and supports 5MP@20fps, with 4MP@25fps (day) / 4MP@30fps (night) as default options. The camera comes with 2.4 mm, 2.8 mm, or 3.6 mm fixed lenses. So, you can choose wider coverage for perimeters or tighter views for entrances.

Therefore, it suits small and medium CCTV setups that need higher‑resolution outdoor monitoring.

Resolution and frame rates

The camera runs up to 5MP@20fps for TVI signals, and switches to 4MP@25fps in the day and 4MP@30fps at night by default. As a result, you get a good balance of resolution and smooth motion.

AHD also supports 5MP@20fps and 4MP@25fps, while CVI uses 4MP@25fps/30fps. CVBS runs in standard PAL/NTSC. This makes it compatible with many DVRs and existing coaxial cabling.

EXIR night and low‑light performance

The bullet has EXIR (extended IR) with Smart IR up to 30 m. So, night images stay clear without overexposing very close objects.

The minimum illumination is 0.01 Lux at F1.2, or 0 Lux with IR. ICR day/night switching gives color by day and crisp B/W at night. DNR (digital noise reduction) improves image clarity in dim scenes.

Design, durability, and power

The camera uses a rugged metal bullet housing with IP67 rating. Therefore, it resists dust, heavy spray, and outdoor exposure.

It runs on 12 VDC and connects via coaxial cable. So, installation is simple and cost‑effective. Mounting brackets support standard wall or eave installs.

OSD menu over coax and lens options

The camera includes an OSD menu that you can control “up the coax” through the DVR or monitor. Therefore, you can adjust resolution, signal mode, and IR settings without touching the camera.

Lens options are 2.4 mm, 2.8 mm, and 3.6 mm fixed. For example, 2.4 mm gives a wide view, while 3.6 mm suits closer areas like gates and entryways.

Compatibility and video output

The model supports 4‑in‑1 TVI/AHD/CVI/CVBS output. So, you can switch modes at the DVR to match your recorder.

As a result, this camera works with many modern TVI/AHD/CVI DVRs and can also integrate into older CVBS systems.
