1. What do the Omni Directional antenna connect to? Is this equipment supplied under this project? If so what brand?
· Omni direction antenna are intended for cellular signal boosters. Engineer does not have a band preference. Coordinate with VA for products that work with existing VA systems.
Omni-Directional Antenna: Omni-Directional Coverage Antenna(s) shall feature a multi-band design that accommodates multiple RF band and channels in a single unit.

2. There is also still not a section in the specifications for cameras/Video Surveillance systems but there are cameras listed on the prints. We are unsure how to proceed with those as we do not know if those are to be rough in only or if cameras are also to be included in the quote. Division 27 does not specify if camera cabling is included, and if it is to be included it does not specify what color the cabling should be.
2. Are cameras/Video Surveillance systems to be rough in only or if cameras are also to be included in the quote? ? Cameras needs to be included in the quote. The camera should be a Hanwha model QNV-6012R unless changed by the VA PD. (QNV-6012R - Hanwha Techwin (hanwhasecurity.com) Placement to be determine by the VA PD. It is noted that there is room for only 23 more cameras in the switch.
a. Is cabling included? Yes, To be installed.
b. If included specify what color the cabling should be? Blue CAT 6 E
3. Panic Buttons.
