IDS or IPS has its specific position within a security strategy.

Intrusion Detection Systems (IDS) is now moving towards Intrusion Prevention Systems (IPS), largely as result of organisation questioning the point of a technology that did little more than alert you to a threat, rather then doing something about it.

Generally a firewall will block on what (protocol / service) and who (IP address and/or resource location/name), it will not protect against: an unwanted protocol masquerading as an authorised one, or an authorised protocol with a security weakness or an origin/location that has been spoofed. IPS is beneficial in that it can thwart the determined hacker, block zero day attacks, protocol weaknesses and give the network support staff time to act.
