Imou isn't a brand that's crossed my radar so far, but if you're looking for one of the best outdoor wireless security cameras its new Cell Go smart camera may be worth considering. It's one of the cheapest solar-powered systems I've seen, and has a decent specification for the price.
The camera is available without solar panel for £69.99, and it's just £20 more to add the solar panel. According to IMOU "it takes only a few hours of sunlight" to provide sufficient charge to keep the camera operating continuously. That means you can get a camera you'll very rarely need to recharge for only £10 more than the non-solar Blink Outdoor.
