Channel Vision Frequently Asked Questions
|
Topics:
|
Amplifiers and Splitters: FAQ
What does a splitter do?
A splitter takes one RF or television signal and multiplies it to your desired number. Channel Vision makes the highest quality RF splitters available. Please note: each time a coax cable is split the signal strength decreases. Additionally, the larger the splitter the more signal loss you will experience. Signal loss must be accounted for when designing an RF system.
My picture looks bad, do I need an amplifier?
Not necessarily. Remember ... garbage in - garbage out. If you put a poor signal into an amplifier it will only amplify the poor signal and in many cases make it worse. If your television picture looks "grainy" you may have too many splits in the signal or because the signal is travelling too far of a distance, an amplifier is the answer. Now you simply need to decide how much amplification is required for proper signal distribution. Please check our RF System Design Chart to calculate signal loss in a system.
What is the difference between a Channel Vision splitter and other brands?
Unlike the majority of inexpensive "off the shelf" splitters commonly found at various electronics retailers Channel Vision splitters are PCB based. That is, there is a sophisticated printed circuit board in every splitter to provide a very high level of isolation between signals. Better isolation means less chance for interference and distortion such as "ghosting" which is often caused by substandard splitters.
Connectors and Accessories: FAQ
What is an F Connector?
An "F" connector is the most common connector used to link coax cables to electronic devices. The F connector is threaded for easy connection to antennas, televisions, VCRs and CATV/RF splitters.
What is a BNC Connector?
A BNC connector is weather-proof twist lock coax connector commonly found on commercial video and surveillance equipment. With a simple twist, the BNC locks into place and provides the most secure way for connecting components and coax cables together.
What is an RCA Connector?
RCA connectors are most commonly used for connecting home theater components together, including: televisions, VCRs, satellite receivers, CD players and audio receivers. You can easily identify an RCA type connector as it is usually color-coded: Yellow (video), Red (audio left) and White (audio right).
What is a Low Pass Filter?
A low pass filter passes all television channels below a selected frequency. For instance, Channel Vision's model 3102-60 filter passes all channels below cable channel 60 while blocking everything above 60. A low pass filter is a "key" component for proper RF distribution where modulators are involved as it prevents broadcasted information from interfering with the "in house" modulated channels.
What is an Attenuator?
An attenuator is a passive, in-line device that decreases the amount of signal strength by a specified amount (usually expressed in dB). For instance, Channel Vision's model 3000-3 attenuates or reduces the incoming signal strength by 3dB. Attenuators are normally used after an amplifier in an RF system to decrease the signal to televisions located on short coax runs.
Distribution Panels: FAQ
What is an RF distribution Panel?
An RF distribution panel combines multiple modulated sources with an incoming television signal and sends the combined signal to multiple locations. Distances from the distribution point to each television tend to vary. In order to provide the proper amount of signal to each television set, the panel routes the signal through a variety of amplifiers, splitters, taps and attenuators.
At what point would a distribution panel make sense for me?
Commercial applications such as restaurants, sports bars, hotels, schools as well as large custom homes may require specific amplification for each television drop. Any system with over 8 televisions at distances farther than 100 feet from the distribution point are prime candidates for an RF distribution panel.
What size panels do you build?
Channel Vision makes two standard panels: a 3 input to 8 output and a 3 input to 12 output. We also build custom made-to-order distribution panels for larger systems. In fact, thousands of Channel Vision custom RF panels are installed in some of the most recognizable places and owned by some of the most well-known faces throughout North America.
Modulators: FAQ
What does a modulator do?
A modulator provides a very cost-effective way to distribute audio/video signals to multiple locations by creating a distinct television channel (Cable or UHF) for virtually any audio/video source. Viewing each source becomes as simple as changing the television channel.
My television isn't "cable ready", can I still use a modulator?
Yes. All Channel Vision modulators allow you to create UHF channels as well as cable channels. Or, if you use a cable box to tune to channels you can route the modulated channel around the box via a Channel Vision model 3101 cable box converter kit.
Sounds simple, can I install a modulator myself?
Maybe, if you are skilled in low-voltage installation techniques. Otherwise, we highly suggest that you consult one of our many professional installers.
Can I use more than one modulator in a system?
Yes. In fact you are only limited by the amount of unused channels in your area. Our modulators tune as high as cable channel 135 so it's not unusual for a homeowner to create channels for 9 or more sources such as satellite receivers, VCRs, DVD players and surveillance cameras. "Closed systems" that excludes broadcast television such as hotels and sports bars can create as many 30 channels for their in-house television networks.
Surveillance Cameras: FAQ
Should I buy a color or black and white camera?
Color cameras produce images that are more familiar to most people. However, color camera performance is subject to the available light within the surveillance area. Meaning that a color camera may be the right choice for an area with optimal lighting but may perform well below expectations when the lighting is poor. Black and white cameras, however, generally have a lower "Lux" rating meaning that they perform well under a variety of lighting conditions. Black and white cameras are less expensive than comparable color models.
What is the most versatile camera Channel Vision makes?
Channel Vision's most versatile and popular camera is our black and white bullet camera. The 5005 comes in black or white and includes a built-in 3.6mm wide-angle lens, universal mount and 12VDC power supply. It's aesthetic design applies to both interior and exterior surveillance applications. Additionally, the 5005 and the color version (model 6005) are waterproof so they perform extremely well in humid and/or wet climates.
Can I record a surveillance camera?
Absolutely. The beauty of modulating a CCTV camera is that the modulator creates a television channel for it. Which means that you can record the camera with a consumer-grade VCR. Simply program the VCR to record the camera channel for a selected period of time just as you would if you wanted to record the news on channel 4, it's just that simple.
Leaving your children with a babysitter? Before departing, change the channel on the VCR's tuner to the camera channel and press "Record". When you return you'll be able to view exactly what happened while you were away.
Channel Vision Telephone Entry Systems: FAQ
What is a telephone entry system?
A telephone entry system creates a communication link between an external intercom zone such as a front door or entry gate to every telephone in the home. When a visitor arrives and presses the doorbell, a distinctive sound is sent to the phones to alert the homeowner that someone is calling in from the intercom. With a Channel Vision system, the person inside the home can simply pick up any telephone handset and press a key to begin speaking to the visitor. Additionally, the Channel Vision system includes a relay closure to send a signal to an electronic door strike to release the lock on the door or entry gate.
Isn't telephone entry usually just for gated communities?
No. Actually, with improvements in technology teamed with mass production, telephone entry systems have become affordable for most homeowners. Channel Vision telephone entry systems are a cost-effective way to increase security while adding convenience in any home.
