  • We use the NEC 280/380 projectors in out classrooms.
  • I highly recommend NEC LT280 series projectors. They have a network interface

  • We have not had good luck with our Sanyo PLC-XU73s. We installed 5 at the beginning of the school year. Two had to have the bulbs replaced by January. -Grace Community School, Tyler, TX
  • We had a vendor show us an Epson Powerlight 82C - 2000 lumens, XGA, 2 year waranty, lamp life projected for 2,000 hours, contrast ratio of 400:1, 5 watt speaker, instant off (no required cool down time), replacement lamps under $280. Next week we are going to look at: Hitachi CPX250 and CPX255, 1 year lamp warranty, 2000 lumens, XGA; and Panasonic PTLB20U (will be replaced with the PTLB50U in a few weeks but nothing to look at yet). -Minot Public Schools, Minot, ND 58701
  • BenQ projectors: They are digital, have wireless models and begin at under $1000. They best thing about them is that they are QUIET and our teachers have found them easy to use. The replacement bulb cost is also reasonable and the service is great. -Mounds Park Academy, St. Paul, MN
  • We have been using Epson projectors for 5 years now. During a renovation we purchased 75 Epson 70c in the summer 2001 and have used them quite well since. This past summer we started upgrading them again and chose the 765c. It has similar specs to the one you mentioned with the addition of wireless. The only problems we have had related to kickballs or volleyballs hitting the projectors (ceiling mounted), other than that we haven't had a single failure. We have only replace 4 bulbs in 5 years. - Roland Park Country School, Baltimore, MD
  • I really like the Sanyo line of projectors. The PLC-XU73, for example, provides astounding projection quality. The 3 year warranty and long bulb life make it a very nice choice. District 128 Palos Heights, IL
  • I compared the IP streaming capability of an NEC NP-901W against the Epson 826W (testing on wired connections only). Both are 1280x800 16:10 projectors. The NEC streaming was much smoother -- good enough for fullscreen video (no audio) and excellent in a window. The cursor moves smoothly around th screen. The Epson performed okay, but not nearly as well. It was good for static images, powerpoint, but just not good enough for video, in my opinion. Too bad -- since NEC dropped the NP-901W and there is no replacement. The LT280 (XGA) performs slightly worse than the NP901W but significantly better than the Epson 826W. Also, the NEC software turned on and off the projector. Whereas, you had to use the remote to turn on the Epson before the software could see the IP address assigned to the Epson. - Michael / Burton School District, CA

"Wireless" ProjectorsEdit

  • There are several ways that wired or wireless projectors are referred to:
    • A "wired projector" is most commonly used to describe connecting your computer to the projector with a VGA cable.
    • A "network-wired projector" or has a CAT5 Ethernet cable running to an Ethernet port on the projector, and might also be referred to as a wired projector, but the teacher's laptop that is connecting to this projector is wireless, so it is also referred to as a wireless projector
    • Another version of the "wireless projector" or "wireless VGA" is when the projector has its own wireless card (either integrated or optional) which adds the projector as a wireless device on the network.
  • With the network-wired projector the laptop connecting to it is still wireless. So the laptop connects to the network wirelessly, but the mounted projector is connected with an Ethernet cable. This has more inherent stability and bandwidth than the "wireless projector" in which both the projector and the laptop are using wireless cards. Also, in both scenarios we run the projector ports through the wall to a wall-plate. At the plate (mounted in the front or side of the classroom) you can plug in a normal VGA cable, red/white/yellow video cables, computer mini-plug sound, S-video, etc. and these connect up to the projectors. -Demetri
  • At Norwood School we were very pleased with a Sanyo model of network-wired projector that has the built in Ethernet port. It comes with manufacturer software for the laptops/tablets that initiates the video connection (and allows complete projector control). It also has moderator/client software capability so the teacher could choose any student computer screen to display. This system works well for internet video (but not great for DVD quality video and the audio signal is not carried on the network. We were using the Sanyo Pro xtraX multiverse projector model. At my current school, BGA, we are using Panasonic projectors that have a built-in wireless card. These have been stable, but I don't think they have the same bandwidth as a wired projector. Their software allows us to set a password for projector control. -Demetri
  • Also, bear in mind the audio considerations... both schools I've been involved with also decided to include speakers on the ceiling with a volume control on the wall. this was all extra equipment. -Demetri
  • The Sanyo units that are networked are the PLC-XU87, the PLC-XU83/84, PLC-XU86/87 and the PLC-XU110/111 (lower numbers indicate older models, higher numbers newer models-but the only thing that really changed was the country they are manufactured in). You can try my vendor if interested, he has always been good to me. He is local to DC/VA/MD area, but there are CCS offices all over the country: CCS Presentation Systems 410-796-6001 phone,
  • LFCDS has deployed Epson PowerLite 835p projectors connected our wired Ethernet network and uses video-over-IP Epson NS Connection software to project from Fujitsu LifeBook T4210 Tablets over our wireless network. The setup works very well for displaying Web sites, Windows Journal sessions, PowerPoint presentations, still photographs, and other computer documents. I recommend wiring the projector to the Ethernet network & leaving the Tablet PC wireless. Since the projector remains stationary & the Tablet PC is mobile, this gives the best combination of fast, stable & flexible connectivity. In this setup, the projector just becomes another = device on your wired network, accessible from any computer on your wired or wireless LAN that has the correct video-over-IP software installed. I have not seen streaming video work well over Ethernet connections, whether wired or wireless. First, the video-over-IP software I've seen does not transmit the audio signal to the projector, only the contents of the screen, so the audio only plays from the computer's speaker, which is generally not sufficiently loud for classroom use. Second, the video transfer rate of the video-over-IP software has difficulty keeping pace with some full-motion video, leading to display lag that puts the video out of synchronization with the audio. A VGA cable with 1/8" audio headphone cable whip to bring analog video & audio to the projector will give you the best presentation quality for displaying streaming video with synchronized audio. For all other presentations, the video-over-IP software delivers excellent video quality using your wireless network. For video with synchronized audio, such as a DVD or downloaded or streaming video clip, use the standard VGA+audio cable.

Other items to considerEdit

  • Drop-down motorized screen
  • DVD/VCR/S-Video jacks
  • VGA jack for laptop use
  • Are you installing speakers too? (the speakers of many projectors are pretty small),
  • External speakers might need an audio controller unless they are controlled by the projector remote (speakers can be plugged into "audio out" on projector)
  • Rear Projection: Q: Is anyone using a rear projection system? We are looking into installing a rear projection screen for auditorium use, and I would like to know of any advantages or disadvantages you have experienced using this format. A: It'll eat some of your lumens (so larger projector sometimes needed), and distance between screen and projector will dictate size of image.
