Features
The front panel of the NV-32 looks more like a network switch or PoE injector than a UTP hub, and NVT made good use of the available real estate. Each of the RJ45 connections includes two bi-color LED indicators, with the left one indicating video and the right showing power status. There’s a diagnostic level to these LEDs, with indications for good video, poor video that cannot be equalized, signal present without video, or no signal (off). Similarly, the power LED can detect continuity errors as well as proper operation. There’s a power-on-self-test (POST) that verifies that you don’t have a burned out LED.
On the back, there are BNC outputs for video, RJ45 jacks for telemetry data inputs, a detachable power cord, power switch and a fuse holder with a spare fuse. The bottom of the unit has a main power switch (120V/240V) and a guide to the different power connector requirements for a variety of countries making this truly an international unit. We particularly like the detachable power cord. Many competing units use external power supplies, which can make installation difficult as they need to be secured to power strips and can block adjacent outlets.
Setup
Setup was very simple, and we tested the units with both NVT baluns (power, video, data) and those from other manufacturers. Compatibility was not an issue; we did not see a difference in video quality between the NVT baluns and those from other makers. We connected various inputs of the NV-32 to cameras from American Dynamics (SpeedDome p/t/z) and Pelco, and the outputs to an Intellex DVR, an Axis encoder, and directly to a monitor. Tests were run over 1,000 feet of Cat-5e cable. Lighting conditions were simulated (indoor) and varying (outdoor).
Testing
The NV-32 was tested with inbound video utilizing the aforementioned setup and the lighting was turned up and down to cause the IR cut filter of the SpeedDome to repeatedly activate. The SpeedDome was also put into motion and set into patterns and presets to observe any video problems. All through the testing the video appeared acceptable, especially considering the low lighting conditions in the testing location. The video remained functional and no tearing or problems were noted, even when the only ambient light came from the test monitor.
Conclusions
The NVT NV-32 performed within its rated specifications and no problems were noted during the testing. The unit was intuitive to install and there were no functional problems noted during setup and connection. The automatic equalization worked flawlessly, despite our attempts to “trick” it with varying light levels. While there are other similar products out there, we know of none that have a better combination of features and implementation that exceed what the NV-32 has to offer.
