The world of monitors is changing. The highlights:

We have tested and taken order of a new and superior wireless monitor system.
Sony has stopped making the CRT (Cathode Ray Tube) field monitors that have been used for so many years and is switching to LCD (Liquid Crystal Display) models only
We now offer a Panasonic 17-inch high definition-standard definition LCD monitor

WEVI CAM-WAVE Wireless System With Marshall LCD Monitor
This month we take delivery of a new wireless LCD monitor system. We have been using Black Box wireless links with Optex and Teletest LCD monitors. We’ve never been too happy with this combination because of frequent break-up in the signal and a lack of robustness with the monitors but we were not aware of any other system. Well, a new one is available and we’re so optimistic it is a dramatic improvement that we ordered 15 of them. We expect delivery by late January.

The new system uses a WEVI CAM-WAVE transmitter and receiver which transmits and receives both video and audio signals using wireless LAN technology the WiFi system used with computers for wireless networking. In the tests we’ve done we found this to give a more stable and consistent signal than the RF system used in Black Boxes. We had virtually no break-up while walking around with the camera and remote monitor on several occasions. By contrast, we frequently had break-up with the Black Boxes under the same conditions.

There is a delay of about half a second between the transmitted and received image but we don’t have a problem with this and nor did any of the more demanding clients we asked. The ability to also monitor sound with the same kit is a huge attraction. No more need for a separate director’s audio feed using a radio microphone from the sound mixer or camcorder.

You can get the technical features of the WEVI CAM-WAVE by visiting www.wevi.tv.

We are also changing the brand of LCD monitors we’ve been using. The monitors we’ve used until now are what’s been available and are okay. But again, they never impressed us. The 7-inch Marshall V-R70DP is a different story. It is made in the U.S. by Marshall Electronics. It is a robust piece of kit and from the tests we’ve done it has the feel of being more reliable than other portable LCD monitors. It also has a nicer picture with sharper resolution.

This increased reliability has a price. The WEVI-Marshall combination is heavier and more expensive. But these are minor inconveniences to get what we believe will be a superior and more reliable system.

The transmitter fits onto the battery mount on the rear of the camcorder which means you don’t have to Velcro or otherwise secure it to the side of the camcorder. The battery is then mounted directly onto the transmitter and that battery powers the camcorder and transmitter. This eliminates the need for a power cable.

The director has to carry the Marshall monitor with a heavier and larger CAM-WAVE receiver with two antennae and a slimline IDX Endura 7s battery. To also monitor audio, a special cable that goes into a small amplifier has to be carried. This is more to carry but we are having special bags custom made to make it comfortable to carry this larger load and again, we are convinced this is a much better system.

The jury is out and I hope my optimism is not premature. If you’d like to test this new system yourself phone Dennis or John on 020 7622 9888 and arrange to come in and do so.

Sony Now Only Makes LCD Monitors
If you go onto the Sony web site (www.sonybiz.net) and look up the PVM series of CRT monitors most widely used for as long as I can remember you will find “This model is discontinued” beside each one. To replace them Sony is now offering the LMD series of LCD (Liquid Crystal Display) monitors. There are a number of reasons for this but high among them is the fact that LCD monitors are environmentally friendlier:

the EU considers CRT monitors hazardous waste because of their high lead glass content
LCD monitors consume less than half as much power as CRT monitors
LCD monitors generate less heat and so can help reduce air conditioning costs
LCD monitors require fewer components
LCD monitors last significantly longer
LCD monitors are lighter and slimmer so cost less to store and transport

If you’re concerned about the environment, you can make a small contribution by going LCD. That sounds good to us so we are going to begin phasing out our stock of CRT monitors gradually. The pressing concern among many lighting cameramen is how LCD monitors compare to CRT monitors when it comes to the purity and quality of the colours and the sharpness of the image when you’re lighting an interview or scene.

Sony contends “the LMD range delivers superb picture quality.” We have tested one and are quite happy with the image. We think the LMD models will become the new standard in the coming year so we have ordered ten 8.4-inch models which should be with us by the end of January. The models include the LMD-9050 which can handle standard definition (SD) and high definition (HD) signals including HD-SDI.

The 9050 has been made for broadcast and professional use. It can be battery or mains powered and because it draws less power it will run longer on a given battery than a CRT monitor. It has a full range of inputs: analogue composite, Y/C, analogue component, SD SDI, HD analogue component and HD SDI.

If you’d like to see or try one of these monitors call us during the third week of January and some may have been delivered.

Panasonic 17-inch HD-SD LCD Monitor
We also now offer a Panasonic 17-inch LCD monitor that has HD and SD SDI inputs and the full range of analogue SD inputs: composite, YC and component. If you need a large monitor on location, this is an ideal solution. Unlike large CRT monitors, this one can be powered by batteries. It’s also produces an excellent image and is lighter, slimmer and easier to carry around.

Summary
The world of monitors is changing: CRT monitors are being phased out and LCD monitors are replacing them. This has significant advantages in terms of size, weight, power consumption, flexibility and versatility. Some people may still prefer the colours and image on a CRT monitor but the new LCD models do produce good reference pictures.

If you use wireless monitors a lot, you should try the new WEVI Marshall combination we will be offering later this month. Our tests indicate it is more reliable and produces a better image than other options.

Call us on 020 7622 9888 if you have any questions. Ask for Dennis or John or me (Cal).

This Month’s Question
I’m rethinking how to handle the quiz I have held previously because getting the answer has become more a test of how quickly someone can use Google rather than a challenging test of knowledge. For this month, I am going to handle it by saying if you have a suggestion about what we could do to improve our service or make it more useful to you, please e-mail it to cal@procamtv.com. If we like your suggestion best, you will win a bottle of good champagne. Read below for inspiration.

This Year’s Message
The biggest challenge we face is consistently providing reliable kits. Despite our best efforts, mistakes are still made thankfully on relatively few occasions and it drives us nuts. To address this issue, we have created a policy of “Every Step, Every Time.” It means what it says. Every time a kit is prepared a set group of steps must be followed to ensure each piece of equipment is working well and that everything needed to make that item work is included. In theory, if everyone preparing kits follows every step every time we should be able to virtually eliminate all problems. So that’s what we’re drilling into everyone at Procam. If you have a suggestion that helps improve our reliability and the quality of our service that’s what we’re especially interested in.

And if anyone would like to see an article on something in particular just send me an e-mail and I’ll see what I can do.

Until next time, happy shooting.

Ok, so you’ve read all the cool stuff and heard all the great things about going wireless and then it just hit you. However, that works you don’t know or care but it hit you. That was it, the little voice in your head said, “do it” and that was that. Unfortunately, that was awhile ago and since that “moment” you’ve done your part. You did some research into what was needed to upgrade your computer but it’s all just so darn confusing. You keep thinking, why can’t someone just give me a few basics so I feel more comfortable about this whole “upgrading” process.

If the above paragraph describes you and if you’re the typical computer user it probably does, then it’s time to exhale, calm your nerves, grab a latte and settle in because hopefully this article can shed a little understanding on at least one aspect of going wireless – the network card.

Like most “typical” computers users, you love your computer and you’ve pretty good at surfing the net, using email and you’ve probably even gotten fairly proficient at using your favorite word processing program but when it comes to some of the more technical aspects of your computer or computing in general, you are probably about as close to a “deer in the headlights” as you can get.

Hey, no problem because you’ve stumbled across a source that hopefully can shed a little light into that wireless networking card abyss. See, those searching skills do come in handy.

Let me start out by saying that when it comes to selecting a wireless networking card you can pretty much ignore all the hoopla except for the following three key factors: range, speed, and standards. Ok, let’s do it and take a look at a few specifics.

Below is a typical specification for wireless networking card. This one just happens to be for a Linksys wireless PCMCIA laptop card. Frankly, I can’t tell you if this card rocks or it stinks, I’m simply using it as an example. And with that, let’s take a closer look.

Here’s the description from Amazon: 11 Mbps high-speed transfer rate; interoperable with IEEE 802.11b (DSSS) 2.4Ghz-compliant equipment; plug-and-play operation provides easy set up; long operating range (up to 120m indoor); advanced power management features conserve valuable notebook PC battery life; rugged metal design with integrated antenna; compatible with virtually all major operating systems; works with all standard Internet applications; automatic load balancing and scale back; model no. WPC11

Like I mentioned above, most of the specs can be ignored. To start with, “compatible with virtually all major operating systems.” That means nothing. It’s simply fluff to expand the description to make the card appear better.

Range
Take a look at where it says “up to 120m indoor”. This means that the maximum range of the wireless card is 120 meters — sure if everything was perfect. And by the way, one meter is equal to about 39 inches or 3 feet. However, in the real world where nothing is ever perfect interference caused by thick walls, other power sources and the list goes on could reduce this number by as much as 90% – so just be aware of this.

And without enough range, your wireless network is no longer wireless and therefore – worthless. It serves no purpose to go wireless if you have to keep your computer next to the wireless port in order for it to work or if you have multiple computers to keep them all in the same room to get them to connect to each other.

As a rule of thumb, unless your walls are made of drywall or wood, it’s best to buy about four times the strength you think you’ll need. Even in perfect conditions, get twice what you think you’ll need – just to be safe.

Speed
Take another look at the description and find where it says Mbps. Mbps is the speed of the wireless connection – 11 Mbps is about one and a half megabytes per second. All 802.11b wireless cards have a speed of 11Mbps, while 802.11g cards run at 54Mbps or nearly 5 times faster. And of course, the next generation will be even faster.

Clearly, speed is important to your wireless network because it’s going to directly influence how long you have to wait to connect, how fast pages upload, file transfer rates, and your overall computer experience is always better when things download faster. I don’t know about you but if something takes more than a few seconds to download, I start to get impatient.

However, because there are currently very few Internet connections running at speeds over 11Mbps – it’s really as much as you need, at least for now.

Standards
You’ve probably noticed in the above specs the number 802.11 followed by a letter b. The b is the standard that the wireless device conforms too. Currently, there are 3 standards – a, b and g.

In a nutshell, 802.11b and 802.11g are compatible with each other while 802.11a isn’t compatible with either. Due to the incompatibility issues with the other two standards and because it’s an older less robust standard I would stay away from cards using it.

Between b and g, b is cheaper but slower, while g is more expensive but faster. It’s also worth considering that adding a b-speed device to a network that has g-speed devices will often slow the whole network down to b-speed, making the g-devices pointless. Basically, the network will operate at the speed of its weakest link.

If your wireless device doesn’t conform to the right standards, it’s not going to be much good to you. I often see uninformed people bidding for used wireless equipment on eBay, not realizing that it’s going to be terribly slow and may not work with other equipment they might have. Always check what standard the wireless equipment is using and if you don’t know the 802.11 letter, don’t buy it!

Over the years the wireless technology has made easy to get rid of cables and has taken the task of computing away from desk.  As the technology is advancing it is becoming a household norm and there are some easy things that you can do to improve your wireless connectivity. Let us learn how to do this with the help of computer repair expert.

The first thing that you should do is to position your router. Always remember that a wireless router does not carry far so there should not be any walls that might act as interference. For this reason a wireless router should be centrally located in your home to get the best possible range. All you need to do is to place the router on a flat surface off the floor and away from obstructions. Additionally you will find that there could be interference from the wireless signal. Just make sure that you are using unique wireless channels to limit any sort of interference.

The next thing is to replace your antenna. Most of the antennas that are shipped with routers are small and have omni-directional capabilities. These antennas broadcast signal in every direction and proves to be quite useful if you want wireless connection throughout your house but the range is quite short. A directional antenna can improve its range by focusing the signal in one direction. These types of antennas are known as “high gain” and the increase in signal is measured in decibels (dB).

The other thing that you can do is to get a repeater. A wireless repeater is an easy and safe way to boost the strength of your signal. The function repeater is almost like a router but instead of creating a signal, it relays an existing signal. A repeater is much easy to install but does not require additional wires and cables. You can create a complete connectivity in a home or business network with the help of multiple repeaters. The next thing is to get an antenna booster because it is possible to make antenna and homemade reflector to improve the wireless signal. You can seek information about this online which will help to use materials like foil and cardboard. The common designs are parabolic satellite shape and a “coffee can” yagi antenna. Both can help you to increase range and direct signal though the quality varies in the homemade one.

The last thing that you can try is to upgrade firmware. Router manufacturers often publish firmware updates therefore upgrading your router can provide a performance boost and helps you to access new features. If you are tech-savvy then you can try to install third-party firmware. There are a number of free and safe alternatives that are compatible with your router. You can easily find the ones that have robust infrastructure than official firmware packages.

With the help of these tips you will be able to improve the performance of your wireless connectivity.

Everybody wants to get on wireless these days. It is sort of “the thing to do.” Funny thing though is, nobody seems to know what they are doing when it comes to wireless. They think they crack open the box plug in some cables and away they go. Well, it isn’t really quite that simple.

Issue number one, would be security. You absolutely MUST think about security if you implement a wireless network at your home or office. If you think you are helping out your IT department by putting an access point up in your office so you can move the stuff around your desk more freely, you are sadly mistaken. If you have done this without setting up any kind of encryption, you have just opened a huge back door to your companies network. At home, you may not be so worried. If someone shares my internet, so what? Someone next door could easily setup a phishing scam in the apartment next door, and use your wireless connection for the internet access. Then guess whose door the FBI will come knocking on? That’s right, yours. So encryption is a must, I highly recommend using WPA and not WEP because WEP has been proven to be easily crackable.

Issue number two, would be placement. Before setting up anything, you should do a site survey. Walk around your home or office and look for things that can cause interference. Map things out, and take notes. Take a laptop with netstumbler installed and look for other wireless networks in range and see what channels they are on. Some things that can cause problems are:

*Cordless Phones/Microwave Ovens: These devices operate at 2.4Ghz, which is the same frequency Standard 802.11G/N routers use. Since they both operate at the same frequency, they will interfere with each other’s signals.

*Concrete Walls: Concrete causes a problem, not because of the thickness or the re-bar in it, but because of the water in the mixture. The magic thing about concrete is that it never stops curing, and the water in the wall can cause signal loss.

*Pointing your antenna: Some people think that pointing the antenna is self explanatory, but it isn’t. You can’t point your antenna like you point your finger because the signal coming off the antenna radiates from the sides of the antenna, not the top.

*Wireless Channels: By default, almost all routers come pre-configured to use either channel 6 or 11 (if I’m not mistaken). Find out what channel the surrounding networks are using and select a different channel. As mentioned above, Netstumbler for Windows works well for this as well as kismet for Linux and Kismac for MAC.

*Chicken Wire: That’s right, I said chicken wire. I didn’t come up with this one myself. I had a wireless class at college, and my professor told us about chicken wire. Chicken wire is used in some houses to either hold in insulation in the walls, or is used when putting up plaster walls. The holes in the chicken wire are not large enough to allow the sign wave of the wireless signal to penetrate the wall and thus creates a Faraday cage of sorts.

Issue number three, compatibility. Almost all wireless devices come with the WiFi logo which is supposed to indicate some sort of standard. It suggests that if you have a Belkin router, your Linksys wireless card should be compatible. Well, 9 times out of 10 that is true, but every once in a while there is that 1 time where it is not true. It is almost always best practice to stick to the same manufacturer. If you are a D-Link person, stick with D-Link, if you like Linksys, stick with linksys and so on.

Issue number four, Firmware. The manufacturers of your equipment frequently come out with firmware updates for their products. If you notice issues with your router or card, look on the manufacturers website for a possible firmware update. Lots of times, the update can correct the problems you are having.

Issue number five, loss versus gain. Every time you have to send a signal down a wire you have loss. If you have a long cable going from your modem, CSU/DSU etc going to your router there will be loss of signal. The longer the cable, the more loss. Likewise, the air creates signal loss as well. The farther you are from the antenna, the weaker the signal. On the flip side, whenever you have an antenna, you have gain. Every time the signal comes out of the antenna, or is received by an antenna there is a little bit of gain in the signal. So what does that mean to you? Shorten your cables if possible, and buy higher gain antennas for your routers if you need the signal to travel longer distances.
