OK, just to share my short user experience on 4 cameras which I have laid my hands on recently.
2 were from IPS while 2 were from VStarcam. All these were from MARIX. IPS were sample units MARIX brought in to test its features.
The 2 models from IPS were IPS-Eye01W (2M HD), IPS-Eye02W (1M HD) and T6836WIP (MJPEG), T7838WIP (1M HD) from VStarcam.
A short summary first on each camera for now.
Starting from IPS.
IPS-Eye01W, this is a 2megapixel camera with resolution max at 1600x1200, the max bitrate supported is 4096kbps. It supports LIVE Streaming like VStarcam using the same P2PCAM264 or RSEE APP (RSTP). The camera supports ONVIF so, Synology NAS can pick up the video stream and records to it. It supports local recording to MicroSD Card. Image is definitely sharp on webUI
CONS: No built in speaker, so can only listen but not speak, need to attach external speakers. Not exactly plug and play, factory set IP to fixed IP. so camera will not work in other subnet other than 192.168.1.x. Sound quality wise, I don't think they can match VStarcam for now. There is no AUDIO recording for this camera. It is on only wireless-G max. Slow PAN/TILT swipe on mobile devices
IPS-Eye02W, this is a 1megapixel camera, it have almost the same features as the E7839WIP that I had reviewed before. AUDIO recording, networking drive saving. Wireless-N support. Image wise is sharp.
CONS: No built in speaker, so can only listen but not speak, need to attach external speakers. Not exactly plug and play, factory set IP to fixed IP. so camera will not work in other subnet other than 192.168.1.x. Slow PAN/TILT swipe on mobile devices
T6836WIP, this is a MJPEG camera, improved with PnP feature and LIVE Streaming on mobile. Sound wise is clear as per H6837WIP, wireless-N support, IR-CUT Filter.
CONS: LIVE Streaming on mobile APP will lag more compared to H6837WIP, expected as it is MJPEG. But is clear if you compared APPLE to APPLE with other brands. As you get LIVE Streaming over frame by frame updates.
CONS: no built-in microSD Card slot, this is purely for monitoring only.
T7838WIP, this is the 1megapixel HD camera. Same PnP and LIVE Streaming as H6837WIP. Looks wise, I like it cos it looks cool. Sharp images.
CONS: No AUDIO recording. No recording to Network Drive also. Plastic Mounting bracket is suitable only for up side down mounting. Side mounting will make your viewing looks weird. I really mean weird. This is the same for any models that uses flat mount to the wall.
Above are my personal experience. As of my writing, I know MARIX had release sample clips of the streaming for the VStarcam on their own blogspot. Haven't seen anything yet for IPS.
