ok. we should always comply thanks

so we should position the camera far and use high focal length lens. can we use ordinary camera and just use non explosion housing?

what type of cabling do we use for these environment? what type of piping do we need to conceal the wires?

thanks for the advice. usually where do we position the cameras? and what specification to use?

you need to setup port forwarding on your router. you also need to check if the gateway address is correct on the dvr. if this is incorrect , it will not work.

any comment on 8 ch and 16 ch DVR of AVermedia? is the online quality good?

what brand of mobile dvr have you encountered and what is your feedback regarding the performance of it?

i can't make it work. even if all the setting is correct. is the dvr on passive or active ftp? have anyone tried using filezilla server?

i'm planning to use ip cameras on a ship yard. it has an area of 1 square kilometer. which connection do you prefer wireless or fiber optic? if wireless what equipments do i need ? if fiber optics will be used what equipments will be used?

there is a new model of AVTECH AVC760AS. it is sata HDD already and its web transmit format is mpeg4

ok . sir for gas station and petrol refilling station can you identify the area of hazard ?

thanks alan. so ordinary camera can be used at least 1.5m radius from the pump.

i think the problem there is the time setting for your email.

it might be a bandwidth issue here. you must consider the data traffic for all the switch/hubs from the encoder to the decoder. are you familiar with the Qos(quality of service)? if your switch hub and devices are Qos ready, you can set the priority for you bandwidth. how many encoders and decoders are you currently using? are you already using Gigabit Lan?

we just finished a 3 day installation today. we used CAT5E as signal cable and the weird thing is only the pair of green and orange shows good picture quality. while the pair of blue and brown will give black and white picture and distorted video. what we did was to run a new CAT5E and just use the pair of green and orange. what do you think is the problem with these? can't the CAT5E handle the four video signal? or the cable i used was poor quality? does this have an issue with the computer color coding scheme (only pair of green and orange was used for computer also and not the blue and brown)

don't eat it.. hahaha funny

1. click start (on lower left) 2. click run 3. then type "ping YOURDOMAINNAME -t" then if there is response then it can be reached. if it is request timed out means it can't be reached

try to ping the domain name or ip address to see if it is online. then try to connect using video server e you can if you want to use the software to view. you can also use internet explorer but you need to add it to your trusted sites and set the security to low. not sure about this.

thanks. sir what are the do's and don'ts of using CAT5E?

ok. may be it was just because of poor quality cable

The runs are to long for 2 pairs of the 4 pair. Can you not run a second cat5 cable? or upgrade it to a cat 6 cable, that will work maybe.. that's what i did. i run a second cat5 cable. the original plan was to run four cat5 cables and utilize all the wires then the distorted pictures came up. even if the run for the (blue or brown pair ) was short the picture was distorted. so after figuring out that only green and blue pair is good. we rerun another four wire. only green and orange pair were used the picture was good. at first we thought it was the balun because the run was short. then we tried to swap the good cameras and it was still the same. then we tried switching the wire and we got it. since the the four pair inside the cat5e have same length. it should work for all the color since only the color of the insulator is not the same. but unfortunately it did not. strange isn't it?

ok. just shared what i experienced till now i don't know what went wrong. strange

everything is ok .just got your pm . sorry i was not aware that you created a topic on test bench. competition here is tough. also most of the products here are for low end market. people tend to look at the price rather than the quality. just done a 3 day job on a supermarket here. had problems with the CAT5E its weird that only the green and orange pair have good picture quality while the rest are distorted and bad. how are you scorpion? how's florida ? how's your business?

blue, orange, green and brown have a all diverted twist. You can see it clearly on my picture the deliverance between orange en blue: Here a other picture, green and blue heve the same twist: yes there is a twist. did you tried running 4 cams on a single cat5e?

it also acts like a TDR. i think it was a bad batch of CAT5E.
