I would use the ASC-VRCH wedge camera it is a vandal resistant camera in a housing that will fit into a corner, the camera inside will rotate 360 degrees to allow you to install it either in a corner or up against eve for an easy and secure installation. It is available in a 2.5 or 3.6mm lens (Sony CCD, 50dB S/N ratio, .1 lux) Price is about $165.00 250.426.8100

couple of suggestions: 1. Are the PTZ camera's ID setup at the individual cameras? If for example the camera input into the DVR is on channel 3 is the dome ID setup as adress #3 2. Are they wired in in series or parallel with EOLR (end of line resistor) installed to increase the signal strength?

I would suggest the ASC-AV4120160 - 4B24IR kits It is a complete camera kit including the following: 1 - 4 channel triplex standalone MPEG4 DVR with CDRW and USB for video back up with a 160Gb HD, mtion recording (should get about 3 to 6 weeks of storage depending on the amount of motion recording setup) 4 - 24IR bullet cameras weatherproof 4 - 12VDC power supplies 1 - VGA adaptor (your Dell monitor will work fine) If you set up a internet connection on site, you can review live or stored images and retrieve them if required. Complete system around $1100.00 250.426.8100 is their main office phone number

I would recommend the ASC-540D256 color dome camera 540 line relolution 2.5 - 6mm lens OSB programming to compensate for any ambient light situations

When did this happen?

The ASC-540WPC72IR- 615 camera will be perfect for the job, it has a 540 line color camera with 500 line B/W at night with 72 IR LED's with external trap door for easy lens adjustment, built-in heater kit and cooling fan, IR rated for 265' comes complete with mounting bracket and the lens is a 6 - 15mm varifocal Manual Iris lens for easy installation. 12VDC/24VAC (dual voltage)

What brand of Baluns did you use? It could be the baluns but if you are using a good quality balun then please note the following options. he quickest way to clean up the vdeo signal is to install active (powered baluns on one side of the feeds. This will clear your images up instantly. Another way (less expensive) is to use individual power supplies. The reason this will work in most applications is that with passive baluns and a common power supply you provide a common ground to all of the cameras and the passive baluns will provide a clean path to ground that will be common to all the cameras. This is a perfect scenario for "hunting", ground loops to occur especailly where there are differences in the length of your cat5 cable and 12VDC power applications. When you install individual power supplies the common grounding point is no longer available and in most cases it will help to solve your problem The active balun option will be the surest way to solve your problem, but it is more expensive.

The best way to prevent camera theft is to install cameras in such a way that you have cameras watching cameras so that if one is damaged or stolen they are being recorded by the other.
