Looking for the following Indoor camera Ip Poe Day/night Box/dome Camera will be about 20' from product shelves Lighting is good Budget is 600-700 What have you had good experiences with?

buy a Pelco Cm6800 matrix loop out to the DVR's for recording output coax to the 3 monitors buy 3x kdb300a keyboards. you can then program the cm6800 to grant rights over which cameras to which monitors/keyboards. BTW: Stay away from netvision. William seems pretty eager around here, but the stuff is Mickey Mouse.

I have a client looking for a 24 to 32 channel hybrid dvr. How are the Dahua systems at this level? I've used exacq, but a 32channel hybrid exacq would be over their budget. They only view the dvr when there is an incident from a remote client pc. No realtime monitoring. Nothing too fancy, just something very reliable that they can add IP cameras to. (i.e. onvif would be good) Any input is appreciated. Good/bad experiences with Hybrids at this level. Thanks!

Very interesting. I'm not experienced enough to comment on the voltage difference issue, but it could be a cause. On another note, what kind of monitor are you using? VGA or bnc? Can you try a different monitor? With all cameras connected and in a state of displaying horizontal lines on the dvr. Can you then hook a monitor to each one individually and see the image? (bypassing the dvr)

If the wiring is to changing then the ground loop is present at all times. Most likely at night the ir LEDs are powering on and drawing more power thus generating more current in the loop. Also at night the b/w accentuates the horizontal lines on screen because the contrast is higher. At this point I would say trying out a ground lifter on the dvr is your best direction. The principles of ground loop causes are quite simple, Too many grounds. However, an easy solution is often difficult to implement.

You have a classic ground loop. The reason the wall warts (110 ac adapters) work is that they eliminate the common ground. A ground loop is just as its name implies. Current is looping through your equipment via a common ground. To elimate the problem you either. 1) change cameras to dual voltage 12vdc/24vac cameras which by design elimate ground loops. 2) determine which pieces of equipment share a common ground and remove the ground from one of them. If you google "ground lifter" you will see an example. Looks like a an ad plug with no ground peg. It seems the logical answer is that your dvr and altronix are sharing ground and looping through the power ground and coax. Think of it as an actual loop. Current is passing through the camera, back trough the power supply, into the ground, back into the dvr, out the dvr via the coax and back into the camera. Or maybe the opposite direction, but you get the idea. When you switch to the power adapters, you removed the ground path shared by the dvr.

1) Is the cat5 shield touching (grounded) to any of the equipment? Try ensuring it is not touching/grounded on both ends. Try grounding just one end (via Drain wire) to dissipate the RF to ground. 2) Are you using just 1 pair of wires for the balun? i.e. use just blue + white/blue. Do not double-up (use multiple pairs) 3) You could try using a ground lifter on the DVR to see what effect it has on the noise.

Try this to start. Power up just one camera at a time and see if the lines are present on all, some or in some combination. If you isolate it to one camera, power that camera from a separate power supply. Also, are any of the cameras mounted onto/touching metal that could be linked to ground? What kind of baluns are you using? Have you tried swapping those? I've noticed poor quality with cheap or mix and match baluns.

I've used the 2.5 wrist LCD's and found them too small to properly focus a camera. I've used a 15" 110vac monitor and found it difficult to work off a ladder and find power. I'd like to know from anyone that has had a good experience with any particular LCD test monitor. Budget is not a concern, don't need PTz control, but would like pattern generation. Battery is a must, and would like water resistant. Thanks for any input!

Right now I'm deciding between 1) http://www.camera2000.com/en/cctv-tester-optical-power-meter-multimeter-video-signal-intensity-test.html 2) ideal Securitest 3) http://www.amazon.com/Defender-Security-82-12460-Monitor-Generator/dp/B008I5QHJ2/ref=sr_1_15?s=electronics&ie=UTF8&qid=1356478042&sr=1-15&keywords=5-inch+CCTV+test 1) has a fiber optic tester and a voltmeter 2) ideal is a good name brand 3) has a large 5.6" LCD and also does pattern test I think I would go for option (1) if I knew for certain a 3.5" screen is large enough. Thoughts? Merry xmas

Just realized I may want more in a tester than I realized. The specific client I am doing testing for has many fiber optic multiplexers in place and I have seen a few testers than include an optical power meter. Does anyone have any experience testing the optical signal in/out of a fiber multiplexer? Most of these testers have a 3.5" LCD screen. Is that large enough? Thanks again

Does anyone know if the 9700-MGR software can be downloaded from the pelco site? or can someone send to me by email? I've purchased a CM9700-CC1, CM9760-MXB, 6800E 48x8, KBD300a and 9760kbd (all off ebay) and will be attempting to configure the 6800e as a satellite device via tie lines. This is all for a lab environment so I can prepare for a clients production environment. Thanks

http://buildingskb.schneider-electric.com/pelco/print.php?AID=10386 So it appears it requires 15vdc/2a. So...can anyone confirm that pelco uses the standard of pins 1/2 and7/8 to carry data and pins 3/4 to carry power? Lastly, I currently have a universal laptop power adapter that lists an output voltage range of 15v-20v dc. Am I safe to use such a power supply? Thanks

Bought a 9760kbd off eBay, but it doesn't have the Kbd-ps-1 power supply. I was hoping to make my own power injector. Can anyone tell me what the voltage input should be for the 9760kbd OR the output voltage on the kbd-ps-1 ? I believe power is carried on pins 3/4 Thanks!

Hi there, I'm looking to purchase a CCTV tester. A client with approx 200 analog cameras has asked me to help troubleshoot their system. Which includes, camera signal loss, poor image quality, and the odd failed camera. To help with this I'd like to bring along a tester designed for such troubleshooting. I've looked at the below tester http://www.bytebrothers.com/bb_tester/Low_Voltage_Pro_Main_Page.htm This tester includes a 1vpp test, length and impedance mismatch. I've read elsewhere that peak to peak voltage is better measured with an oscilloscope (which I have never used) Just wanted some on advice on what troubleshooting equipment others may use/reccomend. FYI:analog equipment is not my core business, but the client is very remote and I try my best to help them out when they ask. Thanks!

Looking for a portable CCTV LCD tester that supports coaxitron. Can anyone recommend one? Thanks!

Thanks for the replies! I did look at the cm2 camera master which does measure ire, but since I deal only a little in analog i didn't want to invest in an $800 composite video tester. I guess I am specifically looking to know if Testing for 1 volt peak to peak and/or impedance mismatches(i.e. using the lvpro) is going to lead me to uncovering a solution. Or if I would be better to invest in some other tool better suited to find problems I would otherwise not easily find. Ideal makes a CCTV tester that has a LCD screen and measure ire as well, but once again it's about $800. This is the only client in my area with this many cameras, and all the setups I do are megapixel. So any specific CCTV tester is going to be shelfed after this project. Thanks again for the input

Can the CNB VCM-24VF be used outside? It's cold here in the winter -30c If not, do that make a camera with the same/similar specs that can be used outside? Thanks!

William: 1) The Netvision software supports dual monitors. 2) Netvision support 2x 16port Compression cards (32 channels) in one computer 3) Netvision sells and supports IP cameras to work with their software i've got all of the above. You mention that I need an i5 processor. OK, I've got an i7 processor (even better) What 1155 based motherboard have you set this up with? I'm really on the edge of my seat here...

It was recommended to me to use the dahua/Netvision cards due to cost. I was told by my dealer that the cards would perform the same as hikvision, but the dahua cards were 1/3 the cost. If I could get the cards to boot in the new i7 system, then maybe my problem would be solved, but with the dahua cards installed, the PC just turns on for 2secs then off then on...repeat. BTW: The cards are Netvision DG4216HF (but actually manufactured by dahua PN: DH-VEC8016HB) William, can you recommend to me a motherboard that will work with 2x Netvision DG4216HF cards, an i7 2600 CPU, and 2x Asus Radeon 6850 videocards? Thanks!

Ok. You recommend a core i5 processor. I'm using dual xeon 5160's. Passmark scores the i5 750 @ 4266 and the dual 5160's @ 4201. Almost identical. You suggest 2gb of ram. I've got 4th of ram. You recommend a 512mb video card. Im using 2x ati radeon 6850 1gb cards. You suggest using a raid configuration, which i am using. So, it seems I'm using a more powerful system than you recommend for 30 analog + 6 2mp. However, even with no ip cameras added, im at 90% cpu usage. Once i add an ip camera I'm at %100 CPU. Do you have such a configuration setup in your lab? Have you tested a setup like this. Your company is very reputable, you must have large settle like this?

Thanks for your insight William. I've done as you suggested and setup remote access for Netvision support to log in. I've sent my dealer this info. Can you give me your suggested hardware specifications for the following setup. 30 Analog cameras- D1, 20FPS 6x 2MP cameras, 15FPS Dual Monitor Thanks!

I've got this exact scenario right now with a new client. I've installed 2 dauha 16 channel cards(pci). I'm recording 30 cameras @ 20fps d1 res. With single monitor the system uses about 20% CPU. With dual monitors, the CPU usage jumps to 80% usage. As soon as I try to add just 1 ip camera (2mp) hikvision, the system maxes out at 100% CPU. The system I'm using is a 2x dual xeon 5160 3.0ghz Wd black 2tb drives, raid 1. 4gb ram and dual ati 6850 1gb video cards. It seems the application that displays the 2nd monitor is a CPU hog. I'm thinking net vision is not going to work for dual monitor. I also built an i7 2600 system, but the system will not boot with the dauha cards. I'm thinking the motherboard does not work with the 32 bit cards. Problem is, I can't find a new motherboard that will work with the cards, and an old motherboard won't work with a new i7 processor. I had high hopes for the net vision software after reading good things about it on the forums here. But it seems like maybe it's geared more towards mom and pop stores and not enterprise. Back to exacq...

Or...avermedia. They must have something decent in that price range?

Looking for some feedback on which hybrid systems have worked well for you. I quoted an exacqvision 16channel hybrid, but it was out of their budget. I'm looking more in the $3000 range. Requirements: 16 port analog + IP remote viewing (software/IE) H.264 Must Support well known IP cameras (axis, iqeye, arecont) Thanks for the input!
