Point-to-Point Wireless Video Systems

The point-to-point system is used when a single, remotely-located camera must be connected to equipment that requires a coaxial cable input, such as a DVR, matrix, or analog monitor. Point-to-point can also be used when two or three remote cameras require wireless transmission, but the cameras are physically too far apart to allow for point-to-multipoint implementation.

Point-to-point is the most straightforward wireless system and usually consists of a single Nextiva S4100 transmitter/receiver pair.

Point-to-Multipoint Wireless Video Systems

Point-to-multipoint systems incorporate two or more Nextiva S4200 transmitters and one or moreNextiva S4300 access points. Point-to-multipoint systems allow several S4200 transmitters to share the same RF channel, enabling multiple cameras feeds to be received by a single S4300 access point. This accommodates locations where there are several remote cameras that require wireless connections to the receiving end.

Since point-to-multipoint systems support channel sharing, many more cameras can be deployed in point-to-multipoint systems than in point-to-point systems, which have a finite number of channels available.

For point-to-multipoint wireless video over 802.11: This infrastructure system is used integrate the Verint wireless video encoder with an existing 802.11 WLAN. Data (such as video, audio, meta-data, etc.) can be sent to Nextiva, nDVR, a Web client, or a standalone video receiver.

Point-to-Point and Point-to-Multipoint Wireless Systems with Repeaters

These systems are similar to the standard point-to-point and point-to-multipoint systems, respectively, with the addition of one or more Nextiva S4300-RP repeater units.

Repeater units are necessary when the transmission path of the receiver is blocked by obstacles or when the transmission distance is too great. Deploying repeaters will further delay data being sent through them.

Wireless Bridge Applications

Bridge applications are normally deployed when data in one building is required in another. Two Nextiva S4300 bridge units would be deployed in this case, with one on each building. At times, a bridge system is deployed when a project requires network equipment to be deployed in remote locations that must communicate with a network in another location. In some of these cases, Nextiva S4300-RP units are converted into bridges since they may require 24 VAC power.
