Megapixel Cameras

camera includes an array of 31 LEDs with a

range of up to 30 metres.

Connections include an alarm input and

output. Two-way audio is also supported. The

camera utilises 12V DC, 24V AC or PoE power

input. It is fitted with an integral 2.8-10mm

F1.2 varifocal lens.

Features and functions include backlight

and highlight compensation, SSDR (dynamic

range), SSNR (noise reduction), privacy

masking, support for an SD/SDHC card and

video analysis. The latter includes virtual

tripwire, object appear/disappear, directional

motion detection and scene change detection.

The camera is supplied with a quick start

guide and a mini CD. At first glance you might

think the quick start is a full manual, but it

includes 10 pages per language, in a huge

variety of languages. The CD includes the full

manual, plus a utility to address the camera. A

second mini CD includes a copy of the Net-I

Viewer software.

Installation is simple; connections are made

via the attached flyleads, and a utility supplied

on the CD quickly finds the camera on the

network and allows access. Once connected

the menus are fairly straightforward, but

navigating them is slower when compared to

other cameras. It’s not agonising, but you will

notice a delay when moving from page to page.

The camera has M-JPEG set as the factory

default, but this can be changed. Switching to

H.264 shows that Samsung has done a good

job of implementing the compression, but

latency is just shy of one second. There isn’t

really a lot you can do to ruin the H.264 image.

From 2Mbps downwards motion does create

rebuild artefacts, and forcing it to prioritise

quality over frame rate at lower bandwidths

increases latency, but at the test bandwidth

cap of 5Mbps the camera works well.

Image detail is high, and colour accuracy is

spot on. Greyscale fidelity is good too. The

camera does have a high level of functionality,

and whilst you don’t get the degree of

flexibility available from some of Samsung’s

other cameras, you do get more than many

similar network cameras offer!

As light levels fall, the image retains a high

degree of quality, although you do see a slight

increase in rebuild artefacting following

movement. Colours retain a good level of

fidelity, and the various camera settings

include SSNR, so noise can easily be

eliminated. As with most Samsung cameras,

there is a lot of processing on offer, and over-

use can affect image quality. If the effect is

increased degradation, back off some of the

settings. There is a balance to be achieved, but

overuse of the functionality can be worse than

under use!

The camera holds a relatively noise-free

image until the point when a lack of light sees

colour fidelity slipping away. There are two

settings for the day/night switching point: Fast

and Slow. There’s not much to glean from the

descriptions, and indeed we didn’t find too

much variance between them. The fast setting

saw the camera switch at around 1.8 lux, and

the slow setting saw it switch at around 1 lux.

To our way of thinking, both switching points

occurred a tad too late as the lack of light

pretty much reduced the level of colour fidelity.

A note about the IR illuminators is that the

camera has an adjustment for the intensity of

the LEDs. This can be controlled manually, or

automatically. In the automatic mode, the

camera compensates for objects close to the

camera to ensure that a bright spot isn’t

created.

The IVA function works well, and adds

another dimension to the camera. It may well

sway a number of installers and integrators

looking for a competitive edge.

Verdict

The GXC-1606M from Eneo does deliver a

decent level of image quality, and whilst

functionality is limited, the camera presents a

credible option. The unit would benefit from a

tweak to the compression settings, but it’s not

enough to make it a bad choice.

The GT79AD/P from G-Tec is a budget

camera, but despite that tag - which often

implies lower quality - the unit does perform

well. There are a few niggles: the IR

illuminators do create a bright pool of light in

the middle of the image.

Samsung’s SNO-5080R offers good

functionality, good image quality, and very

good IR illumination. The IVA features are the

icing on the cake for what is a very cost-

effective camera. However, there is one small

fly-in-the-ointment, and that’s the switching

point for the day/night mode. There are two

settings, but the difference between them is

miniscule.

Finally, the SNC-CH180 from Sony is a good

performer, and has the depth of functionality to

address most needs. Image quality is good,

and when all is said and done, it’s the image

that the end user will focus on.
