cctv_down_under 0 Posted January 31, 2006 As I am sick to death of suppliers telling me their product is the best I have arranged for all suppliers to send me samples for testing, I have promised a report on the dome cameras in return for the loan of their equipment. I would like to know what parameters other than the obvious to look for and to place in the report, could anyone please advise on anything I may have overlooked Ease of Install Voltage 12/24 360 Gimble Vandal Resistant or Not Vandal Resistant Range Of Lense Type of additional mountings Dip switch options Test monitor outputs Resolution Lux Rating Warranty S/N Rating Sample Picture of standard picture Sample Picture of Test Chart Sample Picture of BLight scenario Sample picture of night scenario As I do not own an osciliscope...nor can I spell it... is there anything else I should look for in my testing?

JMANOFNVS 0 Posted January 31, 2006 Are you going to rate each dome on different applications such as no lighting, low lighting or various lighting conditions like parking lots, drive threws, halogen versus floresent or phosphorous and such? Share this post Link to post Share on other sites
jisaac 0 Posted January 31, 2006 In order for it to be fair comparison you are going to have to test the cameras under the exact same conditions. Facing the exact same thing. At the exact same time. I recentlly came to that conclusion. You should see the back of my house. Wait i will take a picture and post it. Share this post Link to post Share on other sites
jisaac 0 Posted January 31, 2006 ok now as we talked about this in one post the way this is wired is never how i would hook up cameras on a job site. But for ease, accessibilty, and ability to swap out you will see these done like we fired someone for if they did it in the real world. ( hints as to why this is on the back of my house and not on our office) Share this post Link to post Share on other sites
cctv_down_under 0 Posted January 31, 2006 Yes all will look at the same conditions, well as close as I can get, there is a room here where I can take a BLC shot infront of a window and then close the blinds for night ability as well as look at an oject on the wall with straight edges to test reolution as best as i can and also on the back of Vlado's book is a resolution chart, however it is not ideal as it is so very small. I can not do a true thorough test as I do not have the time, however it should be enough to get a rough guage! Can anyone tell me good reasons why to use full body cameras instead of domes, I prefer full body but customers think they are ugly, need technical reasons...... Thanks Guys as usual!!!

Jasper 0 Posted January 31, 2006 Domes are vandal resistant. Shield camera from environment. Camera position can’t be disturbed. Less lens cleaning with a dome. Share this post Link to post Share on other sites
Gesualdo 0 Posted January 31, 2006 The list looks good so far. You might include ease of access for settings and assembly, any options or modifications available, materials and construction, accuracy of manual and usability of product and manual. Still thinking what I would want to see. I appreciate what you are trying to do. Gesualdo Share this post Link to post Share on other sites
cctv_down_under 0 Posted February 1, 2006 I actually wanted reasons to use Full Bodies instead of domes, I hate using dome cams as they do not give as good an image, but that is not a good enough reason to tell the customer Share this post Link to post Share on other sites

Jasper 0 Posted February 1, 2006 I actually wanted reasons to use Full Bodies instead of domes, I hate using dome cams as they do not give as good an image, but that is not a good enough reason to tell the customer I knew that. Someone had to speak on behalf of the domes. Now that is out of the way. How about those box cameras. Share this post Link to post Share on other sites
rapid 0 Posted February 1, 2006 You've brought up an important point regarding optical aberration (distortion) as this is quite common with dome cameras. Camera view can be clear looking straight out and then distorted if adjusted at an angle. I prefer the box cameras as well, although my clients would like the discrete dome cameras. Nice thing about domes is you can't see what they are actually looking at whereas the box cameras you can. Box housings tend to displace the activity elsewhere. Other items for your list (or clarification) minimum scene illumination focal length fstop backlight compensation power consumption mounting to standard electrical box dome material - clear, smoked, again optical abberation.

JMANOFNVS 0 Posted February 1, 2006 I like domes...more specifically PTZ's but they are easier to set up and so forth but what about dome our wedge or box style housings with box cams in them they have there uses, I think definitly do it all!!!! So how many domes are you going to try? Are you going to use IR domes to? You should ptu them all in there own catagory and put the outdoors on the back wall for the envirnmental effect. Like fogging up and even mese with some flask lights or if accessable by car drive by to get the effects of headlights and such. Share this post Link to post Share on other sites
