Getting rid of Hum Bars within a Video Camera Surveillance System

By Tim Norton

Any time you put in a surveillance camera system, you might on occasion end up with these types of nasty lines across the display. Usually the initial thing you end up doing is return the camera since it has to be defective, only to discover it works perfectly while in the workshop or that the new unit does a similar thing.

The most common cause of it is really an ground loop, in which a voltage variance has developed on one side of the coax cable to the other end, with respect to ground.

They'll occur as various patterns on the screen and even make a DVR to not record due to a distorted sync pulse. Below a few of the visible effects you may see.

There's really no point in accusing anyone for these because they are unforeseen as to when they are likely to occur but they are more prevalent where the surveillance camera is installed in a location that has a different grounding point to the Digital video recorder or display. For example a security camera pole isn't earthed to the same point as the building where the Digital video recorder is. The fact is it is possible to earth loops in lots of other applications like data as corruptions and audio as a buzz.

There are several procedures that should decrease the odds of finding an ground loop but not one will prevent them.

1. Insulate your camera on the bracket. This requires taking away every electrical bond from the video cameras metal case and the mounting bracket but is only required if your mount will be on a conductive area such as a tin shed or a light pole.

2. When ever putting in the coax , be sure there aren't any lacerations in the insulation as a result of pulling it across jagged edges .

3. Where practical, join the earth of both ends with one another. However this is costly as you will have to install extra ground cable to each camera.

4. You can install fiber optic cable connections to your distant security cameras. This is often pricey but does offer additional added advantages. You've also eliminated lightning strikes from flying through your complete system, destroying almost everything. You can put numerous video cameras on one fibre.

Doing at least points 1 & 2 above, in the event you get an ground loop you'll have to purchase a gadget known as a hum bug eliminator and the issue shall magically vanish.

The unit comes in many forms which includes DIN rail or rack mounted but a beneficial one to have in the tool kit is this in-line hum eliminator, which can be put in between the Digital video recorder input and coax heading to the surveillance camera.

Is the HTC 7 Mozart Smart Phone A Phone That Will Meet Your Needs?

By Ahmed Anwar Akkare

A lot of the smartphones nowadays have been taking advantage of the Android operating system, and HTC is jumping in with everyone else with the HTC 7 Mozart; still, it has opted to go with the Windows platform. HTC has also gone a little bit further because most of its current smartphones are in reality a little bit larger than the iPhone. However, HTC hasn't forgotten about Windows Mobile and since Microsoft launched the new Windows Phone 7 operating system, HTC quickly made a statement that it is interested to support both operating systems. Together with the newer platform, the new HTC 7 Mozart features a rather impressive 3.7 inch screen and they have also added many great features.

The Benefits

The Windows Phone 7 platform already counts as a positive for the HTC 7 Mozart Smart-Phone since the Windows Phone 7 operating system is the newcomer gaining a lot of fanfare on its interface and growing selection of quality apps. Microsoft also imposed strict but fair hardware requirements displaying proof that the HTC 7 Mozart has some serious horsepower. 576 MB of RAM is what is making this HTC smart phone operate using the Snapdragon CPU. Microsoft has two projected updates, the first will up the performance and the second will add multitasking, this is where you will actually see the power of this HTC smart phone. To distinguish it from the other Windows Phone 7 siblings, HTC brought in some special software like the HTC Hub app which functions as the portal for other cool applications like the Photo Enhancer and Sound Enhancer for adding effects to those types of files.

HTC has clearly concentrated more on the design than older HTC phones. One glimpse and you will find that the HTC 7 Mozart smart phone features a brand new design that looks great no matter how you're looking at it. Additionally, you need not worry that the improvements will put too much of a drain on the battery as the batteries life is still 6 to 8 hours of use, which is the industry standard. Recording videos is also hassle-free with the HTC 7 Mozart smart phone and with the 8 GB of storage you will have enough room to save all these videos. One thing that some smartphones have had trouble with is the audio, but you will be very happy with the audio in the HTC 7 Mozart smart phone. Even though this unit is great for using with Facebook, the fact that it has an Office document editor is something that really makes this smartphone stick out from others.

Disadvantages

The camera quality of this smart phone from HTC isn't really the best when compared to other phones with the huge 8-megapixel sensor but the Xenon flash and geotagging features pretty much make up for it. In addition, it is not possible to expand on the 8 GB of storage although it should be sufficient especially if you aren't going to record video. Another drawback is that this phone has not reached its full potential yet since the Windows operating system is still being updated.

The Verdict

The fact that updates will be put out for the HTC 7 Mozart smart phone means that your phone will keep getting better as time passes rather than becoming outdated. Windows Phone 7 is a great and entirely original OS and the HTC 7 Mozart Smart-Phone builds on that nicely with hardware and software to back it up.
