Marcel, That distance I would use use CAT5e. With a lot of research you can find why CAT6 isn't what I would use. Coax is great for SHORT runs or with expensive repeaters. I've run over 1200 feet lengths with passive baluns with perfect quality. Skip the cheap baluns. I wouldn't use active / active unless you find it is necessary. It can actually give you a much worse signal than if passive / passive works. Depends on a lot of factors. I use passive / passive first, if needed I upgrade to active / passive, and lastly active / active. Might want to research type of mounting (eg on metal buildings, and the problems you have to deal with correctly - and any lightening, close high voltage, etc). There are a lot of awesome pros on this forum, and each has a different set of experiences and solutions. Some may disagree with each other but all I have seen are incredibly great sources. Good luck with your project, TJ

You can try here: http://www.duncansonline.ca/FAQs/DicoFaq.htm If the link doesn't work on this forum, just put the following together (removing the spaces) http://www. duncansonline. ca/ FAQs/ DicoFaq. htm They have the software for server and client, and manuals. The manual has everything you need. Each of your camera systems w/Pico have a card in them. Each are the servers, and you put the server software on each. Setup per the manual. Yours that accesses all of them is the client. Load the client software on yours, following the manual. You can view multiple Pico servers at once. It's all in the manual. TJ ********************************************* TJ I was looking for Dico Comander in the internet but cant find anywhere to downaload, and to use this software as server do i have to install any dvr card on server computer or not.... Thnx for your help...

Good news! I have successfully used DICO Commander, to do what you are wanting, for a long time. It's free, but watch where you download it from. A quick Google and you will find places to find it. Careful: There are a lot of sites which have it that will dump viruses, etc on your system. I haven't found trojans or any other problems with DICO if you get it from a reputable site. It has been working great for me. The setup is easy and you can view multiple locations at the same time. If you need help just let me know. I'm not affiliated with DICO at all, just like what it does. TJ

I haven't seen this particular problem addressed anywhere. GV-800 with 16 cams hooked up. Worked beautifully for about a year. 1. Now it is taking some cameras and duplicating them into two positions on the screen at the same time. 2. Some (tested/working) cameras are showing as no signal being received. 3. Some cameras have magically moved into appearing on other camera positions. (They were not changed). 4. Since it thinks it has video loss on some of the cameras it automatically reboots itself repeatedly. Think it is a software or card issue? Checked and card is still seated perfectly. Suspecting the GV system has simply glitched and needs to be reloaded, but wanted to get the opinion of you guys before taking any drastic measures. The DVR has been checked thoroughly and it is operating perfectly other than the GV programs. Any experienced ideas are appreciated. TJ

Has anyone on here actually tried Spiderex, or is there something (including home remedies) that help to reduce or eliminate spiders building webs on CCTV cameras? They've been driving us buggy and it's only Spring ! Any sincere ideas are appreciated. TJ

Plexdata / Plexcctv (out of Florida) I used to buy from them and had really good experience with their products. Great shipping and support all the way. They used to use Geovision which is great. Now they say they use something different out of Tiawan and their own software. After several inquiries of them, they have no demo, offer no information as to a manual, and no clue which card so I can at least research it, and see if it is suitable for my clients. Does anyone have any clue which equipment they are using in their DVRs so I can get the info I need? I hate to give up on what was once a terrific supplier, and have to go looking all over again for top-notch equipment and service for my clients. I'm just not inclined to buy blind like that. Thanks!

Oklahoma yes on security systems and CCTV

"I live in San Francisco, CA is this legal?" Yes, it's legal to live in San Francisco. Just not my choice. (Sorry, couldn't resist) Might check the California Statutes. Not an attorney, but likely ok as long as you aren't recording or viewing your neighbors. No audio at all.

Attached are images of the original lens that I am needing to upgrade. Hope they are of help. Still haven't identified type of mount. It's smooth and 13.8-13.9mm, and depth of 7.2 mm. (my measurements) Thanks for helping.....

I have an original lens that I am needing to upgrade. The camera is an outside IR. Any help is greatly appreciated. The replacement lens needs, of course, to fit into the case by being same size or smaller. Here's the puzzle: I have been unable to determine the exact lens mount type. The lens slides into the body (smooth, no threads) and tightens down with a couple of set screws. Lens mount (smooth) outside diameter is 13.8 - 13.9 mm 7.2 mm - Depth What kind of lens mount is that? Don't think it is an M17 "NF Mount". 4-9mm Vari-focal Manual Iris IR Lens Per Manufacturer: C/CS Interface I don't see how.... 1/3" interline Sony SUPPER HAD color CCD Lens Dimensions (my measurements): 40.5-6 mm - Top to Bottom Height 13.8-9 mm - Lens bottom (mount) OS Diameter 27.9 mm - Lens TOP O/S Diameter 7.2 mm - Depth of mounting surface Needing to upgrade the lens from 4-9mm, but first have to determine the type of mount for one to even install. Any ideas? Thanks!

I have a video problem that I haven't seen the answer to yet. Doesn't appear to be a ground loop issue. Am I correct that a ground loop problem should be pretty much consistant 24/7? This problem occurs at specific times of the day when specific heavy industrial equipment is turned on / off. System specs: 12v. Some cameras are powered through box power supply. Affects three cameras which have separate video cabling (cat5e/baluns), and due to their distance from the power supply box, are running off their separate transformers. All three transformers (due to their location), are plugged into the same power plug-in. 1. After exhaustive testing and analysis of video I have narrowed down that the three experience the interference and clarity in unison. 2. The events occur when an employee starts up / turns off a specific piece of heavy industrial equipment that is crucial to the business, in an adjoining section of the building. The interference clears after the piece of equipment has had time to "wind down" and not immediately when it is turned off, if that helps. Any ideas on this one? I'm not having much luck yet..... Thanks! PS. Please don't post any images I may have sent. I will PM them but can't have them floating on the internet or I can have a really upset client on my hands to deal with. Everyone's help is truly appreciated and welcomed.

Probably everyone enjoying the eggnog. Anyone have ideas on the resolution question above? Thanks!

Almost finished with my project and you guys have been a tremendous help. Two Questions: 1. - System with GV-800 16 channel card. I'm running 15 Sony GS262B 520TVL cameras. The quality is not great at all. They were from Gadspot and their other cameras have been great. Any idea how to improve the resolution to get the image quality in a good range? I realize the question is pretty vague. Running at 640x480 and have tinkered with the settings in the Directdraw and De-interlace. Live and recorded are both not great quality at all. Did better with cheaper cameras in the 400 TVL range. Any ideas how to check / improve the quality? The cameras have zoom/focus screws at the back and have adjusted both the full range. 2. Any idea where to get lenses to match those cameras? The factory ones are 4-9mm and I'm needing more in the range of 25 or 50mm that can fit in the housings. The factory has them, but won't let them go unless they are mounted in one of their much more expensive identical cameras. I have the lens specs (dimensions) if that would be a help. Help.....

Thanks Guys! As always, you are the greatest. That was my bet, but I definately appreciate the second-opinions ! TJ

The experts here at CCTV Forum have come through 100%! Soon I hope to help others as much as they have helped me. Here's the problem: Installation nearly completed. Longest range is 1,200 ft with Cat5e and baluns. All cameras so far running perfectly and crystal clear. Sound great so far? Conduit for one of the main trunks was over a commercial garage door. Was temporarily held up in position with zip-ties (which held great) until the final run was completed. Some of the ties released, which let the conduit lower in range of the huge commercial garage door (manual lift). Guy on site was lifting door and when it hung up on "something" (being the CCTV conduit) he repeatedly jammed the door till it opened. Cat5's not broken. Receiving signal. Now has lots of small lines in nearly all of the cameras. I've heard that if spliced (I use 3m connectors that seal) that you can loose half or all of the signal due to the change in the twist, etc, of the wires. So - replace a total of 4,000 feet of underground cabling, or try active receivers, or cut / splice out the section that was damaged..... Damage consists of the cables apparently being pinched at 90 degrees. Any thoughts?
