Lately, I've been installing alot of AD drones using twisted pair. The problem I'm having is I can only focus with the help of another tech due to the twisted pair being wired directly into the I/O board. The only other alternative I have, is to remove the camera and change the jumpers on the I/O board so video is output on the mini coax tail. I would then use my field monitor to focus the camera and then switch the jumpers back. As you can tell, this is very time consuming and sometimes, the process of removing the camera to switch the jumpers back causes the camera to shift, making me have to repeat the process. Is there anyone out there having the same issue as myself? What are you doing about it? Is there a simple solution that I am overlooking? If there are any AD product developers reading this thread, can you engineer a focusing jack (like the discover camera has) on the camera itself, on the side of the I/O board's base or have the I/O board auto sense termination on the mini coax tail (so if i plug a field monitor onto the mini coax, it will automatically switch from twisted pair to coax)....

I have been having problems with these on every site...(32 channel) Problems include but are not limited to; 1. Faulty power supplies 2. Loss of PTZ control (coaxitron) 3. Ground loop problems 4. Issues with termination (i'll have to explain this) If anyone has had any issues with these units, feel free to join this thread. I am relentlessly seeking a solution...I'll post an equipment list for these systems when i get a chance. But every issue that I'm having all roots back to this active receiver... Any input would be greatly appreciated...

I really appreciate the advice from both you guys (surv and cctv sup)... As for the termination on the matrix. On the 6800, the only termination switch I am aware of, is on the back of the unit at each port. Is there another one in the unit, or is that the 9700? I have to do one of these systems today. It's not very big, it's for a very small store (20 cameras). I will verify the termination on the switch and I will also run my cables to the switch first and then loop to the Intellex...I will post when the system is up and running and let you know if the problems persist..

I am in full agreement with the info you both are providing and I fully understand the concept of termination. However, what I am trying to say, is whenever I apply proper termination to this system (meaning, unterminate looping devices and terminating the last in the chain). I am having problems with the images looking white washed and as a solution, I would have to terminate the looping device to correct the issue. I understand this is not proper, but for this system, this is what is required to obtain a usable image... This is what I am try to explain as being weird with this system. I apologize for not thoroughly explaining the issue before.

That's exactly my point. The Intellex is between the active receiver and matrix, yet it has to be left terminated... If not, the images would look white washed...

Yup, I understand exactly what you're saying, What I'm saying is, when I have my matrix connected (looped from Intellex), I always unterminate (hi-Z). However, lately the problem I have been encountering is, when I set the ports to hi-Z, the images on the Intellex becomes extremely white washed as if I did not have a device connected to the looping port... Weird huh ??

Yes it will...AD coaxitron also works with Cat5e and baluns...

Rain-X works great...I'm not aware of any products specifically designed for a CCTV application...

I appreciate the response. I have already put my money on all these issues being root back to the active receivers...I think Pelco is having growing pains... The AD PTZ's are addressed to "893" to accept Pelco's coaxitron protocol...The problem is, some sites look mint, with no problems what so ever. However, other sites has lots of hum bars and over amplification of the video signal (the receiver is set to auto mode) just to name a couple.... As I mentioned in the first post, lately, i have been having some issues with termination...This is what I mean: I have the video looped out of the active receiver to the Intellex then looped to the Matrix...Naturally you would think that I would have to unterminate all my Intellex ports in order to loop through to the matrix....Not so, when I unterminate the ports on the Intellex, most of the shots become extremely white washed and almost looks as if there was no proceeding unit (matrix)....I know it's not faulty patch cables, because I can view the shots through the matrix and the images look fine... Also, these systems are all being installed in the same type of buildings with almost identical infrastructure...The cabling being used is a custom made siamese consisting of Cat5e and 16/2 (power is run home to an Altronix 32 channel rack mount power supply...

Yup, they are designed to support coaxitron protocol...

The equipment these systems consists of, are as follows: (2) Pelco 32 channel active receivers (2) AD 750 gig rack mount Intellex units (2) Pelco CM6800E 48x8 matrix units linked (96x16) (1) Pelco KBD 960 keyboard controller....(wired remotely, approx 300 feet) All cameras are ultradomes, stationary cameras and / or discover mini domes....(All AD) Protocol being utilized is coaxitron.... Everything in the system is running on Cat5E, the only coax are the patch cables linking the active receiver to the Intellex and linking the Intellex to the matrix units... If you need more info on system, let me know...

Currently, my company has decided to trial the march networks 4316 alongside the current Intellex at one of their sites. I am extremely familiar and versed with the Intellex and it will take quite a bit to sway me from that position...Does anyone have any experience with both these products and can give me an honest opinion on the advantages and disadvantages both??... Thanks...

Nope. I still support the Intellex 100%. I think it's one of the best DVR's on the market today...

I figured that much....I think the Intellex is much more user friendly and anyone can spend a few minutes with it and understand how to do basic functions...I visited the location with the march set-up and I had a very hard time figuring out how do do basic things such as search etc...We'll see how my company likes it...I'm still hard set on the Intellex and American Dynamics....

One of the sites I am currently looking after has a National Electronics NLCD16 mux and I can't get this thing to record on a tape. I have used three different time lapse VCR's and all my connections were checked and verified. What happens is, I sometimes get the message "wrong format" at the top of the screen or only 4 out of 12 cameras would be recorded and the quality is the worst I have ever seen. I constantly get these bright green and bright pink flashes on the screen that disrupts the whole image....Can anyone help me out? PS The VCR's are not the issue because I have used all three VCR's with Sensormatic's RV2216 and RV1316 mux's and they work perfect...

Hi, I was researching some CCTV related stuff on the internet and stumbled across this website. I had a look around and it seemed to be very informative . So, I decided to sign up. I work in the security industry as tech support, field support and primary in-house installation tech for approx 60 sites of large retailer in Ontario...

All my projects are inside 94 000 to 194 000 square foot facilities that are temperature controlled... Oh Yeah...Although I do think its rather cold when I have to unload and load my equipment and tools from my car in the parking lot...

Where did you get that from and how much? I need a set like that...

Did you contact your American Dynamics supplier? They should be able to get you the pigtail terminal block and the mirco co-ax or the I/O board...

I have an no-name stripper and crimp set I got from one of my suppliers, I use this on a very consistent basis and have never had a problem. i simply take care of all my tools and they tend to last... PS I did an installation last night and guess what I used to strip my power wire .....My teeth....Works everytime....
