I need a specific mini cctv I have had in the past, but cannot seem to find now. It is ideal for the application I have in mind.

It was a two part set a cctv camera and a rx box that would be wired to a monitor. Both powered by PP9 batteries.

iirc they were used in bird nesting boxes and things like that?

Any thoughts?

Not seen these for years they were only ever composite and the batteries drained out very quick to be useful.

Still being sold on bird/animal watching websites but expensive for what they are IMO.

Chinese product, the Chinese tend to only make stuff if they can sell a lot of them. If they cant sell them they stop making them. Nowadays most cameras go via Wifi to a smartphone hence why sales slowed and they eventually stopped making them, the WiFi ones are available and cheap though https://www.aliexpress.com/item/1005010041998667.html?spm=a2g0o.detail.pcDetailBottomMoreOtherSeller.2.1b2aUCaNUCaNkt&gps-id=pcDetailBottomMoreOtherSeller&scm=1007.40050.354490.0&scm_id=1007.40050.354490.0&scm-url=1007.40050.354490.0&pvid=3c70f2ac-93e8-4464-a3c5-0eef5af9e28d&_t=gps-id:pcDetailBottomMoreOtherSeller,scm-url:1007.40050.354490.0,pvid:3c70f2ac-93e8-4464-a3c5-0eef5af9e28d,tpp_buckets:668%232846%238115%232000&pdp_ext_f={"order"%3A"162"%2C"eval"%3A"1"%2C"sceneId"%3A"30050"%2C"fromPage"%3A"recommend"}&pdp_npi=6%40dis!GBP!3.08!3.08!!!28.58!28.58!%402103919917609541928144809ea156!12000050922449320!rec!UK!1686170910!XZ!1!0!n_tag%3A-29919%3Bd%3A2a4f45d5%3Bm03_new_user%3A-29895&utparam-url=scene%3ApcDetailBottomMoreOtherSeller|query_from%3A|x_object_id%3A1005010041998667|_p_origin_prod%3A
