The Bullard TACSIGHT thermal imager for law enforcement now has expanded capability with the addition of the Utility Block accessory. This multi-function tool attaches easily to the TACSIGHT camera, allowing it to be used for extended fixed position surveillance. Fitted with a standard tripod thread, the Utility Block fitted TACSIGHT can be pole or tripod-mounted for stationary positioning. Because the Utility Block is outfitted with power-in and power-out connections, TACSIGHT can be power-supplied by an external source for extended run times. Recording or transmitting devices, when connected to the Utility Block, can also derive power from the same extended source.
